I'm doing a top swap here relatively soon. I have a low mile L36 that I bought with 20k miles on it three years ago. It now has 60,000 miles on it and is in great shape.
For my top swap, I will have ceramic coated TOGs with ZZP's catless TOG downpipe, intake, colder plugs etc.
I know for sure I can run a 3.8" pulley with the higher compression and that setup. Would it be worth it to get a MPS with a 3.6" pulley? It will obviously be tuned, but if that is pushing it I'll save the $100 dollars and stay with the stock pulley.
What kind of gains (whp) would I likely see? How much boost would likely be produced?
