i have a obd1 b18a w je forged 9-1 comp pistons brian crower h beam rods arp bolts
95 gsr head stock besides larger exaust valves and sk2 pro1 cams aem adj gears
i have stock pump rail and injectors 240 cc on a hogged out stock gsr mani this is where my problem comes in.People say thats not enough fuel for a boosted engine but with a 50 trim t3t4 and my plx wideband and hondata s300 i have got boost a/f around 12.5-13.7 wich isnt to bad on a built motor w 5lbs right if im wrong where should my a/f be? am i working my duty too much? am i wrong please chime in fellas. Car runs and drives good besides the turbo smoking a little bit just stressin this is my first turbo car and im also tuning the car myself

 

i would deffinately get a bigger fuel pump and injectors and lose the stock intake mani! thats all you need to do and you'll be good

 

Are you running the stock valve springs with the pro1s?

Is it tuned?

Sounds like a decent setup so far just need a few things to make it complete. You need some bigger injectors and a fuel pump.

 

correct me if im wrong but wont the spring in the gate go to the amount of pressure its rated at anyways?????

 

13.7 is way too lean.

 

WOW FAIL !

You mean to tell me your running a comepletely stock head with pro1 camshafts? either your full of crap your dont have a clue what your doing. first off pro 1's are way to much cam for that setup and will result in a loss of power throughout rather than a gain. Secondly stock valve train will absolutly fail with those cams. the and running oversized valves with a cam that has that much overlap is a disaster waiting to happen. before you ruin the whole motor, ptu the stock cams in please.

then get injectors and a fuel pump and take it to someone that knows what they are doing and have them look it over and what else is wrong

 

first off i dint build the motor im going bye what i was told was put in it the guy who built it for me had a terrible bike accident and dosent know whats what anymore so for all i know they might not be pro 1 but i do know the motor has been running for three years now with these cams ive never reved it past 9k but it sees plenty of vtec no prob then two monthes ago i put on the turbo no problems yet i know eventually i have to do bigger pump and i want 440cc injectors and then have a profesional tuner dyno tune my car but for now i can only do what my budgete allows me im sure most or yall have been ther before

 

so you have the turbo on there with stock injectors etc. and your driving this around

 

If I was you I wouldn't hit boost at all until you upgrade injectors, fuel pump and get it tuned. ur going to end up destroying ur motor.
