Re: Can I run 6 psi on a stock LS?

I am glad im not the only one that that didnt make sense to

! I would say it would be safe to run 10psi (possibly 12psi) with some good tuning reliably.

You can run 10 psi but not with an FMU. If you are only thinking about using an FMU do not go past 6psi. I didn't read the whole thing, but you also need a missing link or some check valves for your map sensor, so it doens't read boost, or positive preassure.

If you decide to go with the AFC, you should also get bigger injectors, the DSM 450cc injectors are good for 10-12 psi safely, if tuned properly. This is one of the best options if you do not know how to tune and do not want to learn. Go to a shop get it dyno tuned, and don't touch anything.

Uberdata is free, but you would need to go with an OBD1 ECU, and someone that can install the chip and tune it for you, if you can't do it yourself.

Hope this helps

well yes I do have a B20B block with a LS head in a 94 hatch, and a OBD-1 ECU, but really I only want at least 6 psi...YES i'am a -----..very scare i might blow the motor.... if i get a AFC and bigger injectors like the DSM 450cc..will the injectors bolt-right into my fuel rail and what about the wire-connectors?? or do i have to modify.....what else do I need
