Im looking to rebuild the engine on my 2002 sti, but looking to go down a stroker 2.1 kit build, can i buy this kit and fit it all bolt my heads to it and fit a md321t turbo and have it all mapped or will i be looking to have head work done aswell?
Im talking porting, injectors? and maybe even a seperate fuel pump in the boot.....?

 

I went the same route.
At first just wanted to go stroker at the end changed injectors, went parallel fuel rails, silicone intake, turbo etc etc

My thought is no need for porting heads but bigger injectors and uprated fuel pump is a must.

 

i running a walbro pump already and silicone intake so really a rebuild with a 2.1 and a bigger turbo and bigger injectors is all really
