20 psi

[killab443]

Could I run 20 psi reliably with a MBC, FCD, 255 intank and a turbo back exhaust. Using the stock 14b turbo and stock everything else. Im not looking to drive it like this everyday. Someone told me it was possible

I think 20psi is out of the 14b's efficency range, but I'm not sure. If you really want to try and get away with it, get a hold of a logger and a full tank of 116 leaded and start raising it slowly from 15lbs. But I'm no expert.

You MIGHT be able to do it on 94, but I would have a logger to make sure. You should be able to get away with it easily on higher octane gas, but I agree that it's out of the 14b's efficiency range, you will heatsoak pretty quickly if boosting on the street. I would keep it around 18 or so, that should be plenty for just running around.

Add injectors and a front mount to that and you would be fine at 20psi.

I would not attempt it with stock injectors. As meantioned, 20psi is out of the 14B's efficiency anyways. Of course theres always C16, but that would get quite spendy driving around all the time on that.

Buy a small 16G, 550cc injectors, do it the right way and be faster than a 14B @ 20psi on stock injectors.

Yea do you think 18 psi will bring my fwd into 13s with the mods listed. I also am running the cylone intake (as it was ment to be used) and polyurethane mounts. also took out the shafts and a/c

Well, I knew a guy who ran 13.5 in his '91 GSX with MBC, K&N, ACT 2600, 3" turbo back, and 14B @ 18psi on 94 octane (with a logger ofcourse). High 13's are definitly a possibility depending on your driving.
