You could Swap Either a D15B, D16Z6 or if you are looking for power B16A (SIR engine). But for economy try to find a D15B2 with 3 stage VTEC.

Its Non Vtec buddy.

Merry Christmas and Happy New year . Happy Motoring

It could be the Strut top mounts or else the front cross bar as suggested by john cooper .Before replacing the rack get a 2nd opinion. I would advise you to get it checked by the agents.

If you need more power you could get a port and polish done while the head is being rebuilt. Also you could opt for performance cams with performance valve springs.

Never trouble trouble till trouble troubles you. As suggested by the other members use it for sometime till a repair comes up.Doing an engine swap cause of an engine head rebuild isn't feasible. On the other hand if budget isnt a constrain get down an M50 or an M52 that would make the car a lot more fun to drive.

1 You will have to buy 2 sets of speakers. If you go for Components in front you will have a total of 6 speakers. The tweeters can be mounted on the dash or the doors 2 Main consideration is the clarity and quality you are expecting and the amount you are willing to spend. If you will have to consider the brand name, Watts RMS, and whether 2 way or 3 way. I would suggest a set of component speakers for the front. You could buy a set of Infinity or JBL components for less than 18K. 3 If you have a good set of 6X9s you wouldn't actually need a Sub unless you are a Bass freak. But if you really need a Sub a 10" or a 12" would do. And one is enough if you wont play it outdoors. 4 An Amplifier amplifies the sound signal generated by the Head unit resulting in a more powerful and clear signal. Most of the High end speakers are designed to be driven by amplifiers. Most of the modern Head units has around 50W R.M.S per channel and provides good music till about 50% of its total volume without much distortions. But if you are looking for high quality music invest on a 4 channel amplifier as suggested by Komi. Listen to different brands by playing different types of music and select the one which makes u r ears happy

If you want more light 4300K is the best. This temperature has the highest lumens output and wouldn't be an issue when driving in bad weather too. If you want it to be a bit more bluish go for something between 6000-8000K. They would have a bluish tint but will have a lesser output than the 4300K ones. The visibility in bad weather woudn't be great in the 8000K ones so better stick to 6000K bulbs. Try to buy a brand like BOSCH or Philips as they would last longer than the cheap bulbs. HID bulbs never conk off but will loose output over time.

It depends on the upgrade. If you are going for a 6 pot you'll definitely need to upgrade the master pump because extra fluid would be needed to push the extra pistons resulting in longer pedal travel. But for a 4 pot the difference in more or less negligible yet it depends on the car, the piston size of the calipers and the piston size of the master cylinder. If the stock master cylinder has a big piston then you needn't worry much if you are going for 4 pots but would be different if you are going for 6 pots and they are rarely being used on a daily driven car. Hope it cleared your doubt

Brakes It's one of the most important systems in the car. A failure in this system could cost lives ,therefore one must make the car stop faster if it's being made to go faster. Most of us only think about the 0-100kmph time but 100-0 time too is very important. The major areas of improvement are the brake pads, calipers and discs. Brake pads The brake pads are important in any car equipped with disc brakes. A good quality set of brake pads could make things stop well but a better set would bring things to a halt faster. What I refer to as a better set is a performance set of brake pads. These brake pads use rubber with special qualities used to improve braking. Most of the performance brake pads provide a better bite over the stock ones. Also they are more resistant to heat and will result in lesser chances of brake fading. Brake discs The more area of contact means better stopping, therefore bigger discs would result in shorter braking distance. Slotted discs and Drilled discs cools faster because they dissipate heat better than a solid disc but the latter is prone to cracking .Mostly these are for the looks factor. Brake Caliper Performance calipers is a good upgrade because they provide more brake force on the disc due to the increased no. of pistons. Normally an upgrade to a 4 pot set would be adequate but would have to go further in race applications. Rear Disc conversion This is a great thing to do if parts are available freely. It would improve the stability during hard breaking . The flaw in drum brakes is that they get heated quickly under continuous hard use which would result in the brakes fading. If there is a big difference in brake forces between the front and the rear wheels the car wouldn't feel stable under hard braking. Braided steel hoses The braided steel hoses improve the pedal feel which improves the response. Since the expansion due to the increase in temperature of steel is lesser than that of rubber the alteration of fluid pressure is minimal due to the increase in pressure. This improves the response and wouldn't fade even if the fluid temperature increases greatly. - END-

Transmission The transmission system delivers the power of the engine to the wheels. A stock setup on a high powered motor would lead to loss of power ,therefore the correct combination of components should be used based on the application and the conditions. The main components of the transmission system are the gearbox,flywheel,Clutch and pressure plate. Gearbox This area needs changing only if one is planing to do a high powered build or else a conversion/ race application. Would be most probably a waste of money on a car with subtle modifications. For those who think of changing the gearbox an LSD box with Dual synchro would be ideal because dual synchro would hold up to high rev shifting and the LSD will make sure that power is generated evenly enabling the owner to keep all the power down to the wheels. For race application a close ratio box would be ideal because it provides better acceleration through the gears but the term defined as "Close" would vary between manufacturers. Clutch and Pressure plate The clutch transfers the engine power to the transmission. A slipping clutch would result in loss of power. When considering a clutch upgrade drivability should be taken into account. A Racing clutch would keep the power down when shifting at the redline yet would be a real headache to drive in the stop and go conditions. Also the pedal pressure increases with the use of a performance pressure plate cause a performance pressure plate uses more force to engage the clutch that results in minimal slippage. There are many types of clutches in the market other than the stock replacement ones others are graded as Heavy Duty, Stage 1, Stage 2 or else as Street ,Street/Race and Race. The latter being the more aggressive type and is not advisable to use in a daily driven car. A good Street or heavy duty clutch would be the wiser choice considering the level of traffic we experience daily Flywheel A most common fly wheel modification is the lightening of the fly wheel. A lightened fly wheel provides better acceleration due to the decreased moment of inertia. But if its too light it would affect engine braking which is necessary in a daily driven car. Also if its the stock fly wheel that is being lightened the strength of the fly wheel could be hindered by the removal of mass. Also it should be balanced properly once lightened.

1 Could recommend WEPR 2 Would close somewhere between 25-45k (Depends on pipe diameter) 3 Might be not. Could take a day depending on the place u get it done 4 Can be a bolt on no modifications if it's stock diameter 5 Hidden factors like what? Btw whats the point of doing this? Are u planing to go for a bigger pipe diameter?

Handling "Power is nothing without control". In order to utilize the maximum power the handling department should be improved. The improvements would be based on the requirements,chassis strength and the suspension setup of the car. The basic principle of attaining better handling is lowering the center of gravity which could be done by either lowering springs or Coil overs. The tires too play an important role in handling because they are the things which keep us connected with the road. So lets see what changes could be made Tires Tires govern at least 50% of the handling department. Good tires could improve braking, traction, cornering and ride quality. The quality of rubber, thread pattern, traction rating etc should be taken into consideration when choosing a tire. A tire with soft rubber would provide better grip and braking and also would improve handling but it would be prone to punctures and will wear out easily and for tires with hard rubber it's the other way around. Low profile tires would improve the looks and handling at the cost of ride quality therefore they should be chosen wisely Lowering springs Lowering springs is the cheapest way to lower the car yet it's not the perfect measure cause the lowering springs reduce the suspension travel and would result in a very stiff bone jarring ride on stock shock absorbers But it would improve cornering and the looks and also will provide more traction during a hard launch. Coil over kit Coil over kit consist of sports shock absorber which has adjustable dampening and coil springs with adjustable ride height. This is the perfect setup for someone looking for perfect handling without compromising ride quality greatly. Yet coil overs are very expensive when compared to the lowering springs but would be the ideal setup specially for our roads. Strut bar A strut bar could be used to strengthen the chassis and to reduce body roll. This connects the two strut towers which would provide additional reinforcement and will reduce chassis flexing during hard cornering. It also improves the vehicle stability while speeding. There are 3 types of strut bars, they are 2 point, 3 point and 4 point namely. The commonly used ones are the 2 point and the 3 point strut bars. The 3 point provides additional stiffness by connecting the strut tower to the body of the car. Lower tie bar / Sub frame brace This is used to connect the two lower arm mounting points. It strengthens the subrame and would result in better cornering. The main disadvantage is the reduction of ground clearance and could lead to damage of the sub frame if it hits and object at a high speed Suspension bushes Suspension bushes could be replaced with either polyurethane or hard rubber. Polyurethane could be too stiff for a daily driven car therefore hard rubber is what is recommend. Start off by replacing the front sway bar bushes with Polyurethane / Hard rubber ones if one needs improvement go ahead and replace the rest but not advisable on a daily driven car as it could hinder ride quality.

Fuel System It is one of the most important systems in an engine.Modifying it could lead to more power and better throttle response at the cost of mileage.The basic components that could be modified are the Fuel pump, Fuel pressure regulator, Fuel rails and the Injectors. Adjustable Fuel pressure Regulator This component could be used to adjust the fuel pressure in the fuel lines as required. An increase in pressure would lead to better flow specially at a demanding instance (Full throttle). Also it could be used to alter the drop in fuel pressure incurred when opting for higher capacity injectors. This could solve the delay in throttle response which could result in using higher capacity injectors with the stock fuel pump. Very high pressure is not recommended on stock fuel lines. The forced induction engines should have rising rate fuel pressure regulators to vary with boost. Using it on a NA car would lead to the mixture running rich. Injectors The injectors doesn't need changing unless it's being used for a high compression NA motor or else a Forced Induction motor running on high boost. When choosing injectors the spray pattern and the impedance should be taken in to account. The point to change the injectors is when fuel starvage occurs. So it isn't advisable on a daily driven car as the full potential will not be taken use most of the time. Fuel Rail A performance fuel rail will lead to better fuel flow and fuel atomization. Will also improve the throttle response and will lead to a gain in full throttle. The interior of a performance fuel rail is smoother than a stock one which improves flow but some fuel rails have a very large difference in internal diameter to that of the stock one. So this could cause a drop in fuel pressure so the internal diameter should be considered when selecting one. Fuel Pump An uprated fuel pump will definitely lead to better flow. This this upgrade is required only if you are running an aftermarket engine management with higher capacity injectors. When selecting a fuel pump the flow rate should be taken into consideration. The flow rate is measured in liters per hour. Also some of the aftermarket fuel pumps are noisier than the stock ones this too should be taken into account if its a daily driven car. Most of the fuel system modifications are interrelated with each other. Therefore one should select the best combination considering the application. In my point of view for a daily driven car a good quality adjustable fuel pressure regulator would be more than enough to meet the demands.

Iridium is stronger than platinum and also lesser resistance than platinum. So Iridium has better conductivity and longevity than platinum. But considering the price difference i would suggest platinums

Ignition Spark Plugs A Spark plug is used to ignite the mixture of petrol and air inside the Cylinder.The choice of spark plugs should be made depending on the application. A stock motor wouldn't benefit from a set of race plugs because it wouldn't be exposed to such conditions more often. The factors to consider when selecting a plug are the plug gap and the heat range. A spark plug with a small plug gap will produce a weak spark while a it would cause misfiring if its too big. Also a hot plug could lead to pre ignition causing detonation while a cold plug could lead to a loss of power in the high revs Iridium Spark plugs Iridium is a very rare metal which is related to platinum. It is stronger than copper yet has more resistance than copper. Copper is the best conductor but it erodes away easily. The plus side in using Iridium spark plugs is there longevity. The iridium spark plug has a thinner pointed electrode when compared to that of a conventional spark plug this could improve the ignitability slightly but will have negligible effect on performance. Plug wires A wire with a larger cross sectional area made out of a better metal than the conventional wires could improve the spark when coupled with a performance ignition coil. The larger cross sectional area means lesser resistance which would result in higher voltage passing through it. Also most of the performance plug wires are colored so it improves the engine bay look too. Performance Ignition Coil A performance ignition coil will produce a higher voltage than the stock coil which would result in better burning. And engine running a rich mixture would benefit more because more gasoline particles would be combusted during the cycle which would lead to more power and lesser emissions. A proper ignition system with good spark plugs, performance wires,performance coil with proper ignition timing could lead to an increased in the low end torque which would improve drivability in street

Thank you. More to come soon

Thankx. Yup a lot more to come

The main aim in creating this thread is to educate people about performance modifications and to share the knowledge regarding them. And also to build a more performance oriented car community rather than one based on fiberglass and huge spoilers Why do modifications? It's done in order to improve things in various departments of a vehicle such as handling,looks,speed,braking etc. A modification can make or break a car,so it's important to choose them wisely. What to start with? It depends on ones preference and what one really wants from his or her vehicle. If it's just the looks a good body kit and a set of alloys would be more than enough to satisfy ones need.But if you are more of a petrol head and into performance one might take the performance path. Performance path is for those who like to feel,hear the difference and not just see it. In my opinion its the best path to take because you can enjoy it at the end of the day. Where to start? It depends on the vehicle one would select for modifications. To make things better the weaknesses should be treated first."Power is nothing without handling" but to start with handling one should know what the final product would be and what figures he is looking for, so for someone who hasn't got an idea about it, starting with engine modifications would be the wiser thing. But for someone who would feel that stock power is enough the brakes and handling is the way to go. Engine Modifications The extent of the modifications depend on what one is hoping to achieve and the amount of cash allocated. Then one would have to choose whether he is going in the NA route or the Forced Induction route.But if it's someone whose wanting to get more power from an everyday car whilst keeping its drivability and practicality it's better to go in the NA route. Some of you'll might disagree but its cheaper when compared to forced induction. The power of an engine is mostly based on air,fueling and ignition,so in order to improve things these departments need improvements. So lets see what could be done. Intake The intake provides oxygen for the combustion of fuel in the cylinder. Therefore more oxygen leads to complete combustion which leads to more power. Colder air contains more oxygen, one might have realized slightly improved throttle response during a cold day or in a cold area like Nuwara eliya. The EFi engines consist of various sensors located in the intake route in order to measure the flow,Oxygen percentage,Intake temperature etc. The values obtained by these will lead to the performance of the engine. If we could decrease the intake temperature more fuel would be added to the cylinder due to the more oxygen present in the air resulting in more power and vise versa. In order to do this most performance engines come with a cold air intake which manages to keep the intake temperature down most of the time Cold Air Intake (CAI) and performance filters Cold air intake is one which is directed in a manner which sucks in air which is cooler than the air inside the engine bay. Normally these intakes are routed through the front bumper or else below the engine bay. These systems have proved to improve the gains but has their down sides. The increase in pipe length will decrease the throttle response slightly and there are chances of water going into the system due to floods etc. If one has a well ventilated engine bay (preferably one with a large front grille) a performance filter will improve the power slightly. A performance filter is one which has better flow than the stock filter whilst filtering the dust and particles. But most of the time the filtration suffers. So one should consider the filtering property too when choosing a performance filter because it would have adverse effects on engine life specially in a country like ours. Cone intake vs Stock replacement performance filter The cone intake would let in more air leading to a slight power gain and also will produce the induction noise which some prefer. The gains will be mostly in the high rpm range and the low end gain would depend on the car and sometimes might be negligible. Also when fixing a cone intake it should be fitted in a place where it could draw in cool air sometimes placing in the stock location of the air box might lead to a drop in power once the engine heats up due to hot air being drawn in. For better performance a heat shield could be used to prevent it from drawing in heated air. The stock replacement performance filter would improve the low end mostly and is not fancy as a cone intake. It doesn't alter the induction noise either yet quite practical for a daily driven car. The gains from these modifications depends on a lot of factors such as the displacement of the engine,compression,flow rates etc. The gain in figures would be anywhere between 2-5bhp (*subjective) Throttle body and intake manifold modifications Increasing the diameter of the throttle body will lead to a gain in some engines while it would kill the low end in some others. The ones running high compression would gain from this cause of the increased amount of air fed into the engine yet it might lead to a drop in air velocities in the ones with normal compression. Throttle body polishing would increase the air velocity which would lead to a slightly better throttle response. Bigger intake manifolds will make a difference in a high compression NA engine or one which is having forced induction but will not be ideal to be used one cars with normal compression ratios. Exhaust The Exhaust system consist of many parts namely the Exhaust manifold,down pipe, catalytic converter,muffler. Exhaust Modifications Before doing an exhaust modification one should know what he wants from it. If it's just the sound a free flow muffler a.k.a Beat barell would do. But if it's performance one would have to modify the components of the exhaust. The exhaust system is based on the backpressure which is needed to some extent for a daily driven car but too much of it will hinder the performance. So the the extent of the modification depends on which rev band power is needed. If one wants to squeeze a bit of power with a tight budget a Cat back system would be ideal. Cat back exhaust It is a system consisting of piping with larger diameter and a performance muffler. But the changes are done after the catalytic converter. This would lead to a better mid and high end whilst keeping the stock low end power. But when choosing the pipe diameter bigger isn't always better. Therefore the piping with the correct diameter should be selected. Exhaust manifold (Headers) These would be changed according to the gain expected. If its a turbo conversion these would definitely need changing. The pipe diameter depends on the application its being used on but they have a gain over the stock manifold which sometimes reduces the velocity of the exhaust gas due to its size and construction. So for someone looking for more power the headers would be a good option. But they should be fabricated by professionals and also it's better to use thermal insulation to keep the engine bay temperature low. Muffler The muffler is used to muffle the sound of the exhaust. The choice depends on the owners preference but most of the time a proper performance muffler which is made by a reputed company sounds better than a Beat barell which is made in Sri Lanka. The free flow is said to reduce the back pressure slightly but the gain in negligible in some cases. The sound it makes depends on the size of the internal pipe of the muffler, The amount of glass wool, the size of the tip etc. A small muffler on a large engine will make is sound real bad while the other way around will hinder the performance of a small engine. There are two types of exhaust setups that could be used in a conventional 4 cylinder engine. First one is known as a 4-1 and the other is known as 4-2-1 4-1 Exhaust Here the 4 pipes on the exhaust manifold is fitted to one exhaust pipe which is known as the down pipe. The gains of this kind of system is mostly on the mid and top end. It is an ideal set up for racing because the engine is running in the high rev range most of the time. 4-2-1 exhaust Here two pipes from the exhaust manifold is joined to a single pipe. This setup improves the mid and low end gain and most suited for street use. Please feel free to share your views regarding these and to correct me if I'm wrong. More information to be posted soon Drive Safe

Since yours is a Spoon tuned engine it doesn't need any headwork. The ITB's will kill the low end and would be a pain to drive in the traffic.

If you want a brand new one you could checkout the Volkswagen Polo.Also try Suzuki Swift Sports,Honda Fit RS.If you want very good performance and Fun and wouldn't mind a two door try a Honda Civic EP3 Type R. There was one for sale sometime back

I've been following this thread for quite a while and it's really nice to see people doing something different to stand out from the rest and make the ordinary extraordinary. What I feel is that if you are customizing a car u should sit back for a while and think what u want out of it and how it should look like. Once that goal is set it's just about achieving it step wise Komi's Project R is a good example for it. And one day you'll have a thats BUILT NOT BOUGHT and drives and performs in the manner which u want. Hats off to all your efforts and Good luck for the oncoming ones

congrats komi . Patience paid off finally. And its built not bought here after
