2zz Swap on Vitz/Yaris SCP90 - Toyota Yaris Forums

I'm a regular over Newcelica.org. as "many".
Ive been building these engines for a while and know their potential and their problems.

Nice swap but why are you using the auto ecu...of course your going to have problems...it's meant to be used with an auto 4 speed and it's gearing. You might not even be hitting Lift(second cam) and having the auto ecu I bet your not even getting higher then 7900 rpm.before it's pulling timing and fuel. Get the proper ecu for that engine combo....or get a power fc which is a very descent standalone for the 2ZZ.

2.25 isn't enough for a high revving 1.8 ltrs. get a minimum of 2.5" exhaust.

The Transmission doesn't come with LSD in any configuration (C56, C60 , C64 e.t.c). There's a couple of good one out there that will do the trick. Monkeywrench has a couple available. The left wheel has less weight on it making it easier to go into a wheels spin. Your torque steer is exactly whats happening to the right wheel that is doing all of the pulling, effectively pulling you to your left.

The only concern of using the stock AC is the pulley size. The 2ZZ can rev safely to 8400rpm (stock valves and springs) so that small pulley is going to be over spinning from it's intended use.

Your next mod should be a wide band.
