f22b1 turbo stock fuel pump and injecters. do i need to upgrade if im only pucking 10 psi? and i have a bypass valve on my map sensor but the check engine light keeps comming on from time to time. i have a acf vtech and i played t=with the settings and got a huge performance boost but it runs like **** sometimes, when i full throttle it, i acts like its not getting anough fuel but when i back off to half throttle it has the power. and one more thing should i invest in a turbo tuned map sensor if so please throw me any web site for parts.

thanx much

 

Yes upgrade.
Also if your running auto think about a 5speed swap. autos don't like much more power over stock unless built.

 

yeah at 10psi!? thats pretty high for a stock motor no tune. youre gonna burn it up along with that transmission. back that boost off until you can get some fuel upgrades and a tune. run 6 psi and take it nice and easy until you fix everything. youre probably running very lean and are going to burn valves and damage other internals.

 

You definitively need bigger injectors, and if your running at 10psi, I hope your tranny has been either overhauled or built up, or it will go.

Second, make sure you tune your timming correctly, especially with that big of a boost.

If you have a rebuilt Auto tranny you will have more power then a 5-speed, reason being is you don't lose AS MUCH boost with an Auto, as opposed to a manual, and you probably can't shift anywhere near as fast as a built auto tranny can..

 

Sweet! what would be the best injectors and fuel combo?
And will I need and engine management system?

 

get a hondata and you will need some good old 550cc backed up by a nice walbro 225...

p.s: this should be under the turbo section

EDIT: also get a tranny cooler
