What size of turbo do I need for my oz rally 03
Do I need a programmable compurer to do performance changes??

 

depends on how you want the car to drive, and yes you will need to reflash and tune the ECU...also larger injectors...


smaller turbo's will spool faster, but won't be efficient at higher rpm, so they fall flat well before red line. bigger turbos will be laggy, but will be more efficient at higher RPM, in turn making more power.

 

Thanks but...can i get a performance chip for all these changes?? If not...how do i reflash and tune my ECU??

 

Nicksega,

There is no easy route when boosting. It will need to be tuned. All boosted applications are different so each car has a different tune. You'll need a tactrix 1.3U cable or a 2.0. The 1.3U logs faster and is cheaper. Most of us also just buy a used evo 8 turbo. They're cheap and easy to find here in the evo for sale section. The hardest part of boosting is finding a manifold. There's no longer anyone producing them. Take a look in the "forced induction" section and read thru some builds.

 

ive been told that the best turbo option for our lancers its to get an evo 8 turbo

 

16g is a pretty good size for a 2.0L engine.
