JRSC setup
I got some questions regarding my JRSC setup, heres the parts i have
LS/vtec, gsr head
forged pistons, GSR comp.
CTR cams
DC header
One question is what size throttle body should i use, eventually i want to run 12pounds, also will an AFC with 440's be sufficient for this if i use a boost retarding ignition?
Thanks in advance

Re: JRSC setup (93supercoupe)
The GS-R throttle body should work just fine. The S-AFC can support 550cc injectors and that should be more than enough for 12psi. If you opt to use the S-AFC I've got one that was installed but never tuned and i am getting rid of it for a stand-alone unit, let me know if you are interested.

Re: JRSC setup (turbodav)
When you up the TB size on a supercharged car, you'll see some real positive results. Most blower tuners will agree that tha biggest TB you go that will still allow for a good idle and throttle response is the best bet.
FYI, Richard Holdener found a 10whp gain going from a 60mm tb to a 65mm unit on a SOHC jrsc powered car. More recently, I found some really nice gains going from a stock GSR tb, to a tapered GSR tb.
