Abysmal perfromance of 2005 Vitz RS

[ncp13]

Mine has the factory 15inch rims and stock size tire and 180000km and it revs out without hesitation


I dont know the weight difference of a NCP13 with a NCP91 maybe it gained a few kilos..


Stock factory figures where 0-100km/h 9 sec and 190km/h at the limiter and about 107bhp.

I would still check for compression though as I am weird like that

Well, my wife's IST (NCP61 same gen as your NCP13) is fine as well.

Will see how it (vitz rs) behaves with 1ZZFE throttle body...

Regarding compression: there is no need to check it, as it does not consume oil, there is no blow by, there is no idle issues, oil is clean etc.

What I believe has happened is that Toyota was lazy and used the same CVT safe tune/throttle map on manual car. While throttle response on CVT equipped car is not important on manual car it is somewhat important (unless you hate driving).

If I wanted a boring car I would have bought an automatic Tiida for half price.

Regarding performance difference between two - yes Gen2 is slower than Gen1 due to 80kg difference (Gen1 950kg vs Gen2 1030Kg). This difference would not explain anaemic throttle response.

What I am saying is that toyota took all the fun out from the engine with their very conservative tune. Bloody 3 cylinder Sirion is more fun to drive than this thing.

Well if emissions is not a problem in NZ maybe you should backdate your ecu and throtle to gen 1 :)
Or try those kits that remove the lazynes from the systems with e-throtle.

Good luck
