Well I just picked up a HAHN s20g and manifold. The turbo has dyno time and 600miles on it....but I want a smaller turbo. I need something just for around the city and up the hills. I have a 99 10th anniv eclipse 420a with an automatic and I want incredibly quick boost times and to not even have to run an intercooler. What do you think? Is the s15g what I need? Anyone know when it will make 6-8lbs of boost? Anyone willing to trade my s20g for their s15g?
