Evo-Chamal

dam! That's one hell of a lineup. I'd really want to see a Zonda in real life. That's got to be the most rare and outrageous car in that group!

So recently I noticed a ticking had developed that sounded like valvetrain issues, so I pulled the valve cover off to see what was up and here is what i found: A chunk of cam lobe about 1cm square was missing from one of the intake lobes of cylinder 2! Preliminary inspection seemed to indicate that the closing side of the intake cam lobe looked to have been smashed repeatedly as if with valve float. Several of the lobes on the intake sides also showed signs of severe beatings. I thought this was odd since titanium springs and retainers were installed, specifically to prevent valve float, when these more aggressive GSC 272 cams where installed. I know I've never had the car above 7000rpm so I was concerned as to why the damage had occurred. So I contacted the manager at GSCMotorsports to ask him about the failure. Turns out that my batch of cams was one of their earliest sets for the 4G63t and it has a known manufacturers defect! Incorrect lobe surface hardening Well it sucks that nobody told me that until after they had failed!!!! Ah well, such is life! We have a saying in the tuning world: "The candle that burns twice as bright, only lasts for half as long." I'm using this downtime as an excuse to do more stuff to the car heehee! I will post more updates in a little bit!

Yes! I think I found a long lost uncle on here! He pm'd me. Turns out Nishan is an uncle too, what a small world It took less than a week on the forum to find relatives.....only in SL hahahaha Yey for long lost relatives with Evo's

Hahaha thats the man!!!! OMG lol ahh its asitha the man lol The Rising Suns!!! hahaha what a small world

Ah nice! Do you know any SL's currently working at Cummins? I only know of 1 fellow but I don't even know him well. This place is full of suddhas and indians... **************EVERYBODY PLEASE READ THIS************* On a completely unrelated note. My mom just returned from Sri Lanka and she was telling me that while she was there, she had gone to some relatives house and found out that the husband of that house was into Evo's! She mentioned his name, something like Nishan or Nishanth or Nishantha I think? Is there anybody in SL like that you guys have heard of, I expect him to be a bit older maybe 30's, because apparently he is a family man now. But my mother tells me he was a big Evo nut in his day, and he even got some of his young nephews involved in the Evo scene as well. I don't know any of these fellows personally, but it turns out we are distant cousins and the husband fellow is some sort of distant uncle! I can't help but feel that despite being half a world away we are being drawn together by fate and Evo's! How cool is that? If anybody here knows the people I'm talking about PLEASE PLEASE direct them to this thread so I can meet them! That would be the coolest thing ever!

Oh snap! Vishnu tuning, I used to hang out with those boys when I lived in Cali! In fact, I had 2 close Sri Lankan friends out their (both with Evos as well) who were two of Vishnu tunings first customers. In fact, the black and silver Evo 8's in the pictures here: http://www.vishnutuning.com/evo.htm both belong to Sri Lankans And on top of it all those Vishnu Spec Ohlins where actually prototyped and developed on my buddies silver 8! The same car was even taken to American Touge with the final produciton Ohlins and driven by Keiichi Tsuchiya (Drift King) himself! Small world huh? Sri Lankans representing in the evo underworld hehehe!

Good lord you have a real 6.5 TME???? They are so rare I've never even seen one in real life! How did u manage to get that piece into SL?

Sweet man! Great pics, looks like you've done lots of track events/autoX's! Maybe we'll meet at a track one day And machan I want Ohlins coilovers you lucky bastard. dream top of the line pieces in my opinion. You going with newer models? DFVs or Flags?

thanx man I'm working at Cummins engine company these days. The auto industry is hurting bad! I'm lucky to even have a job in this field... Awesome! Pics and details plz!

Thanks for the kinds words guys. The short answer to that is no, not reliably. But that said, its not a fair comparison to make. The all new aluminum block open deck 4B11t motor in the new Evo X does not have the robustness under extreme stress that the iron block closed deck 4G63t has. Its not a matter of technology, the dual MIVEC system in the 4B11 is far superior to the standard 8 or the single MIVEC 9, but the 4B11 motor from the get go has been designed with future emissions regulations and fuel economy in mind. I have done a lot of research on the X motor and everything from the cam profiles to the piston bowl shape take obvious compromises in the name of improved emissions and fuel efficiency. Sadly that is what needs to be done when developing an engine these days. I know first hand, I deal with these issues every day it's fulltime job as a performance engineer. When the 4G63t was designed the rules were much more lax. That era in the late 80's and early 90's allowed engineers the freedom to create heavily overbuilt motors (something cost would not allow today) with relatively little restriction in terms of emissions and fuel economy. The results of this can be seen in several motors of that era, specifically, the 2JZ GTE 3.0TT I6 from the Supra turbo, the RB26DETT 2.6LTT I6 from the Nissan Skyline GTR, and the 4G63T from the Lancer Evolution. Did you ever wonder why those specific models were able to reliably turn out double or triple their factory power output with relative ease? And why we don't see any new engines these days that have the same capability? The culprit is cost/emissions/and fuel economy restrictions. From a purely technical perspective, the days of the common street driven 500-900awhp Evos died with the Evo 9. Does that mean it is impossible to have a 800hp Evo X? No, but it will be a far more difficult project. With upgraded internals and upsized turbo I would expect to see Evo X's pushing between 500-600hp, but that is approaching the physical limits of the block. There are ways around it through serious block work, like re-sleeving the bores with uprated steel sleeves, but the cost and reliability issues still need to be proven. Reliability is key. Any motor can be boosted to oblivion and make 500hp for one dyno run. My car has 78,000 miles on it (125,000km) and is daily driven in the rain and the snow, and the salt, and the heat 64,000 of those km have been on the built motor and it has never let me down in any way despite hard driving, track days, and attacking the mountain roads like you would not believe. Yes! I agree wholeheartedly, passion for cars seems to be a standard part of Sri Lankan guys! All my cousins back there are just like me in that regard. And I absolutely don't presume to have the best or anything near it. I'm just another crazy nut of a guy who has to work his ass off for every $ that goes into his car. I don't get handouts of freebies or any of that its blood and sweat and tears. I've been dreaming of cars for 23+ years but I've only been driving and experiencing performance and engine tuning for 10 years so in the wide scheme of things I'm still a noob compared to many many far more experienced people in the industry. yea, took of the plates for the photoshoot. I don't need my license plate floating around the internet. I'm currently located in central Indiana, but I used to work in Silicon Valley for VW/Audi Advanced R&D and most of my tuning and driving and general tomfoolery happened when I was living in Cali :-) Thank you, that was the exact idea. You'll note that I've gone for a more stealth look with the car, removed the big wing, fitted Evo 7 lights instead of the clear stock Evo 8 pieces and blacked out the "Evolution VIII" badging. The reason is, I would rather nobody else know that I'm driving an Evo. The car draws enough attention as it is due to the noise and wheels/brakes. The place I'm living in is full of suddha's who like to drive big pickup trucks and I would rather they think that I'm driving a regular Lancer. That saves me a lot of hassle from police jumping to the conclusion that I'm "Fast and Furious" and other such BS. I can do without all that headache, hence the stealth guise on my car. Subtlety is the name of the game, and unless you know Evo's you probably won't notice it in traffic. "it's not only about # of bhp and the torque, it should be a combination of handling and control" I couldn't agree more. It seems some on here have taken the fact that the car was built to 800hp specs to mean I drive around with such a setting. Don't get me wrong, lots of people in US do that, but having that much power in an Evo means the car is basically a drag machine only, and I am not a drag racer. The car has never been launched in its entire life. Not even once. In fact, I'm still running it on the stock clutch despite the power upgrade :-) The car is 800hp capable but like you said, numbers are not the only piece of the puzzle. To be fast on the mountains roads or the track the car needs a balance of power and handling. And that is what this car has been built to achieve, the heavily overbuilt motor was done for the sake of reliability more than anything else. I am far more into roadcourse and technical track/backroad driving. I just find it to be far more interesting and challenging than steering in a straight line and upshifting as fast as you can. Which is ok, but requires little skill in comparison. As a result, my car is setup to handle, and without trying to sound like a cocky asshole or anything like that, as it sits in daily mode, it would crush an Evo X on a tarmac race track. That is exactly what I have built it to do. I've driven an Evo X many times and it is a fantastic car, I'm not going to try to say its not a good vehicle, because it is easily the best in its class (head and shoulders above the latest generation STI which is, sadly, useless in comparison). But there have been some major changes made to the Evo X design philosophy that have, in my opinion compromised the essence of Evo somewhat. First of all, the Evo X is ~300lbs heavier than an Evo 8/9. That kind of weight gain in a car as focused as an Evo is sacrilege in my opinion. Its like driving around with two buddies in the back seat all the time! (... or maybe one fat buddy lol) The interior trim/features are far better and far more refined than either the Evo 8 or Evo 9. The cabin of the Evo X is a genuinely comfortable and pleasant place to be, and it can be outfitted with fancy things like Bluetooth, 30GB HD, touch screen Rockford Fosgate sounds system, etc... Don't get me wrong, these things are nice to have, BUT, if I wanted a luxury car, I could have a BMW 335 for the same money as a Evo X and have a far nicer interior as well as a fancy badge. What has happened here is that Mitsubishi has "softened" the Evo X a little bit to appeal to a broader market. They have succeeded in adding some refinement, and luxuries, but the penalty in terms of weight and isolation is too high a price in my opinion. The Evo is supposed to be a focused performance machine, not a soft comfortable luxury cruiser. In trying to steal some BMW 335 customers, Mitsubishi have lost a lot of the raw, undiluted, violence, the brutal feedback that made the older Evos so awesome. I didn't buy my Evo for the interior, or the paint, or the looks, or any of the poser BS, the car was built to perform. That is all. And the Evo X compromises some of that purity to appeal to the mass market (in my honest opinion). The aftermarket for the Evo X is still maturing, but even so, comparing the on track performance of the Evo 8/9's and the Evo X's, the difference is immediately apparent. A stock evo 9 runs away from a stock Stock evo X (GSR or MR). example: http://www.edmunds.com/insideline/do/Drive...rticleId=124246 And the heavily tuned Evo 8/9 runs away from the heavily tuned Evo 10. example: http://www.youtube.com/watch?v=ZAbD4QLMQvs Technically speaking thought the Evo X is a tour de force. The AWD system in the Evo X is, in a word, stupendous. It is HEAD and SHOULDERS above the AWD system in the USDM Evo 8/9's and a step up from the AWD system in the UKDM/JDM Evo 8/9's. Torque vectoring allows you to throw the car into a corner beyond what anyone would consider the limit, and the car will actively send torque to outside wheels to rotate the car around its center of gravity and get it back on track. It works very, very well. I wish I had such a system in my car. In stock form, the Evo X motor feels more like a V6 than it does a boosted I4. The small turbo spools very quickly and the torque punch comes in as low as 2000rpm. The downside is that the little turbo runs out of puff at the top end, making the car feel like its run out of breath when the revs get up high (although I'm sure this can be addressed with aftermarket tuning/bigger turbos). Its not a bad thing, just a notable difference. Also as I mentioned earlier, there are mechanical limitations inherent to the aluminum alloy block that will limit the 4B11's potential. It's still a fantastic engine, its more than a match for a stock or mildly tuned 4G63. But at the same time, whether it can match a 4G in the long term in performance and durability, remains to be seen. Conclusion? As a street car in stock form the Evo X is the better car. More refined more comfortable, looks cooler, better fit and finish, equally fast on the street. But if you are a dedicated performance nut? the car for you is not the X.

First let me introduce myself as I am new to this forum. My name is Chamal Abeysekera, I'm 25, I have a masters degree in mechanical engineering (automotive!) I currently live in USA and work as a performance, combustion, and emissions engineer doing engine calibration. My extended family lives in Rosmead, Colombo? I think. I'm sorry I don't really know the exact names and locations in Colombo. Anyways I came across this Lankan car lovers forum and had to join! I know the car passion burns strong (its got to be in the blood!). Despite the fact that I've lived most of my life nearly 14,000 km from SL I find whenever I visit, the passion for cars runs equally strong in all my Lankan aiyas and mallis So without further ado, let me introduce my current vehicle 2003 Mitsubishi Lancer Evolution 8 Highlights include a fully built 2.3L stroker motor, turbo upgrade, titanium valvetrain, 3" turbo back exhaust, ceramic coated tubular headers, 780cc injectors, etc..etc.. I'll post the current state of tune and list of mods for those of you who like such details. In daily driver mode the car is making around 480hp at the crank (400awhp) on the lowest boost setting (21psi). The pistons/crank/rods/bearings have been upgraded to withstand 750-800hp (650awhp) reliably on higher boost and the titanium valvetrain is built to withstand 10,000rpm (with increased stroke I limit shifts to under 7700 for safety margin). The car was overbuilt so that there would be a nice big margin of safety for reliability purposes plus the option for upping the power if I feel like it. Depending on boost settings and available traction 0-60mph time's are somewhere around 2.9-3.3s and the car will easily pull more than 1.05G lateral acceleration. I never launch the car hard though, (I'm not a drag racer) and it physically hurts me to think about abusing the drivetrain like that, but I do push the car hard on the curvy mountain roads and on the racetrack. The car is built more to be a quick street car that will see occasional track days at the local roadcourse. The advantage of the 2.3L stroker build over the standard 2.0L Evo motor is greater low end torque as well is ~20% increased exhaust flow which gets the turbo spooled up much quicker than the 2.0L for more power at lower rpms. Ideal for street use.
