Hey guys I just purchased a h22a prelude and it seems somehow it may be boosted to 8psi. I know stock JRSC setup is 6psi and I always hear of people boosting stock h22's to 9psi with a Motorvations pulley or accord crank pulley. My first question is is it still possible to obtain this Motorvations pulley or is he out of business? Does he have a website cuz I can't find it? If I go with Accord pulley option is it the 98-02 Accord crankshaft pulley I purchase? Can I use an aftermarket lightweight/underdrive Accord pulley instead? Second does anyone know how a H22 can be tuned to run at 8psi? All my research has not come up with an 8psi JRSC setup. They all jump from 6 to 9 to 12. I can't even find 10 or 11psi setups if they exist. So I'd like to push as much psi while maintaining a stock motor, but I don't know what pulley setup to get or where.
Secondly I keep seeing people going back and forth on the 2.5 inch exhaust vs. 3 inch exhaust. I believe Preludes are the exception to the rule and actually do run better with a 3 inch exhaust, especially if I go 9psi but I need some expert advice here. I tried on preludeonline.com and got nowhere, thanks.

Actually I have called that number and got no answer or voicemail so that's why I questioned whether or not he is still in business and he actually has no other way to contact him or learn about his company but to call him? (no website)...Anyways what about the exhaust question

No idea. I haven't talked to Jim in a while. Google him and see what's up maybe? I know he used to hang out at the Forced Induction Integras forum.

As far as exhaust, I'd say go with the 3". Only use 2.5 if you want more torque down low and a more restrictive top-end.
