I mean this in the nicest possible way, but I hope your friend is a tried and true pro with throwing a turbo on the IS. It's not like doing a supra or any of the previous 2jz because of fly by wire. Good luck in your adventure and be sure to keep us updated!S38 FLY said:Well check this out. My friend has all the software and wire harnesses for the E-Manage set up. He told me that he can reprogram and retune the whole system. What a lucky break! So far it's worked out that I had all the right connecitons to get what I need (so far).
