  1. Congratzz mate! That looks an awesomely clean car. Are the tail lights an aftermarket addition? Seems different to the one I remember from FD1. Please post some interior pictures as well. I only have driven FD1 autos, I'm sure the manual would be even better. Enjoy your new ride!
  2. Now where are the photos that we all are eager to see? 😁
  3. Congratz! She looks stunning, great color as well. Am also a huge Mazda fan Headlight modification looks cool as well (Hope it has been done properly). Waiting to see some detailed pics in a new thread!
  4. @chan5 if you are still in the hunt, saw that there are couple of Mazda2 cars around Colombo for sale in ik***.lk site - 2016, imported by agent as per the ads.
  5. Hi @chan5, @iRage won't a properly maintained Mazda 2 be another viable option for these requirements?
  6. For this specific engine (1KR-FE), I think there weren't a lot of gains. Hence, for this specific case only, I would say its not worth it. But depends on what you expect really. But if it was a larger engine / an engine with forced induction IMO it could have been different.
  7. Reconditioned TB = 15k Aluminum spacer = 2k for material and lathe work Extra long bolts and nuts = 0.5k Gasket paper = 0.5k Other stuff I already had, including a cone air filter (unbranded), silicone couplers etc. I did not go for a proper CAI, but assembled one from PVC pipes and a few bends. Idea was to test it out first.
  8. Just putting down what I think.. Spacers would work in engines with carburetors.. it could improve the air fuel mixture uniformity since fuel and air is mixed inside the carb and then you get this swirling/circulating effect right after by this spacer.. but with EFI, even if the air swirls just after the TB, not sure how it can have the same effect.. Again, this is just what I think.
  9. Hi, This is a short summary of what I did. Got the throttle body from a 1300cc engine (1NR). This has a significant size different compared to the Vitz 1KR original one. However the bolts positions which fixes the TB to the intake manifold are the same. Swapped out the control boards from the original one to the new one. The manifold side opening is around 35mm while the new TB opening is about 45 mm. Therefore, made a small adaptor plate from a block of aluminium to have a gradual reduction from 45mm to 35 mm. Thickness of the aluminium block was 3/4 inches. Its similar to a throttle body spacer like below, but not neat as this of course Got some help from a local lathe shop. Also cut out a small gasket from gasket paper to fit between the adaptor plate and new TB. The installation order from the side of the intake manifold was Manifold with original gasket | throttle body plate | custom gasket | new throttle body Afterwards got some help to fabricate a small CAI (pipe diameter: 3") and used an unbranded cone air filter with a dust cover, and was good to go Improvements that I noted: Induction sound change due to the CAI. Had a bit of a growl in it now. For me was not really important tho - I know many of you petrol heads will disagree Increased pulling power in the mid to high RPM range. After about 4000 RPM it has a improvement in the pulling power, but not anything ground breaking - can't expect anything of that sort with this 1KR engine. Downside: Decrease in torque/pulling power in the lower RPMs. I think this could be because of the intake air velocity being low due to the wider TB and air intake. So yeah, this was my experience after doing it. Since this mod kind of reduced my low end torque, I have reverted back to the original setup. However, I now use a drop in K&N air filter with some custom air tubing routed to an opening in the front grill of the car where it can suck in colder air specially when the car is moving. The original air tubing sucks in air just from the left side of the engine, which IMO is not the best place for a cold air feed.
  10. So, I actually went ahead and tried this out. Did it out of curiosity mostly, to find out what happens. And yeah it does change the throttle response characteristics, but could not drive around a lot after the mod. Also, I'm still to pair this mod with a better air intake. Will post the results once I do.
  11. Thanks. I checked the some of the popular throttle controllers like P***l C*******r, but yeah those are awfully expensive. No idea about the price of the Toms. Guess it should be pretty expensive too. There are few people who seem to have done this. Therefore I thought the throttle body swap should be workable.
  12. Thanks @ajmand @iRage. I actually thought the ECU will compensate with adding more fuel. Isn't that the case ? And yes, can get a ECU tune too. I'm looking for quicker throttle response yeah. wouldn't the ECU add more fuel when it detects the larger amount of air via the MAF sensor? Thanks, did not know about throttle response controllers. Will certainly check them out. And I assume I can anyway do a tune after fitting a throttle response controller (If I'm able to get one down amidst this situation)?
  13. Hi folks, I own a Vitz 1.0L (1KR-FE) car. I'm looking for options to increase the initial throttle response - and thought whether swapping the throttle body for a larger one, possibly the throttle body from either Vitz 1NR-FE (1.3L) or 1NZ-FE (1.5L) - would make any difference. The stock throttle body inlet diameter is 38 mm as I found. When swapping, I suppose matching the larger throttle body outlet to the intake manifold would need to be sorted, but I guess a matching plate (starting from the new throttle body diameter to gradually reduce to fit to the intake manifold) would do the trick. In addition, will be coupling this with a CAI. My questions are: Anyone who has attempted the same here, who can share their experience? Could this give a improvement in the throttle response? Or is it not worth it? Thank you.
  14. I went ahead and switched to 175/65 R15 and have no complaints so far. No noticeable reduction in acceleration and the car seems much more planted and stable.
  15. Nice! Lol same concern here mate. Thankfully the Vitz is happy with 92 octane. Is it in the same stretch of highway you get this noise? I experienced a similar noise from tires few times in the highway (in a different vehicle though). Checked the tires and then noticed that in the particular stretch of highway, the carpeting has been removed and roughened for re-carpeting, hence the noise. The noise went away once the re-carpeting was done.
