What kind of power gains rough numbers would i see with a set of cosworth m3 cams on no tune just bolted in an evo with basic bolt ons

 

^^ first off you need to be tuned. what size turbo you running??

 

put them in and dont tune it and let me no how it turns out.

 

no tune and your car will run like $h!t. I have the M3's with every possible bolt on for the most part as well as a ported IX turbo and on 91 I put down 355/355 on a dynojet. This was in a evo IX too if that helps you any.

 

Thanks i thought for sure you have to tune with them but people kept telling me no they bolt in ****ty cams need a tune but there....I have a stock turbo now but soon to have a fp red its on an ix
