i think i am wanting to go with a "bigger turbo", probably the ko4 just cause i will have money for that and i wont have enough for the gt28r. so what kind of mods will i need for it? i know exhaust and chip but i will get thechip with it and i already have turbo back exhaust,so i know it helps to have injectors and fmic and then fpr but can you run the ko4 without thosefor awile and getthem eventually?

 

im looking to do the same thing im kinda peicing it all together such as the fmic, stage 2 clutch, i am not too sure what ll is need besides turbo and programming i just kinda find out as i go

 

one more question is what kind of programing are you guys running with a 2000 a4 with the ko4 cause i know that was a weird year and i cant fined anything out about a chip for a 2000?
