hey whats goin on guys. so i have had my turbo civic for 6 months now and im looking for a little more power. its LS/VTEC. factory B18B1 bottom end, with b16 head and gsr head studs. im also utilizing a garrett t3/t4 turbo. im running 7psi right now. i just got a greddy profec-b boost controller and im wondering what i can eek out of my motor without sacrificing head gaskets or my ring landings. any advice? oh and i have a walbro 255 310cc injectors. i have a p28 ecu chrome style with a gsr map and a cartech fmu.

 

get bigger injectors, ditch the FMU, get it tuned to 12-15 psi. i'm running 16 lbs on my bone stock LS

 

Yeah, I wouldn't go much higher than that with an FMU. I know the "tuning is everything" mantra is overplayed, but it is very true.

 

yeah what bigbadboy and 91da9 said....310s might be cool for what your doing, but play it safe, make sure you got the fuel to support your goals....and if you got something to tune it with....get a tune on it....and then you should be fine
