its going into a mk2 golf, i have a 1.8t engine with forged rods. Ill be using an AGU Head too. What i know is the std ko4 turbo off an S3 etc won't get me past 285 isn, but I've been told a ko4 off a tfsi engine will. So will i need bigger injectors than the 440cc std ones - like genesis 550's with a 4 bar fpr. and will the tfsi ko4/manifold fit straight on an AGU head. Ive had a ko4/023 bam engined mk2 golf before and when i convert the next one ill be looking for a little more power as is the usual way i guess cheers for any advice given.
