Thread: Knock Ret. reading at 3.

oh! we'll im going back to that muffler place and telling them i dont want the res. and fix the other piping. and them im going to do some insane tuning. my belt i got i can fit on the 3.5 pulley.

Im about to order some rocker arms from zzp. Do you know if i have to port my heads and stuff to even run that small of a pulley.

If you look at the zzp website. they had a gtp that he did alot less mods than i did and ran a 3.2 pulley it was a 99gtp. he didnt port anything. he just had a 160 t stat
