i have a b20v fully built. i dont know exactly what i have. but what i do know is the head is stage 1, the block is 50 over, and im running hondata. i also have srt competition fuel rail and aem fuel regulator. the car turns on but it doesnt even idles it just turns off and if i take the vacumm from the brake buster it stay turn on but i sound like crap. this is my first time with a fully built engine so im pretty lost any help will be appreciated

 

you have a built motor & you don't know sh*t about it.
who did the work & tuning?
make sure you not dumping too much fuel inside the engine

 

jerrybuilt did the work it has his mark. i lowered the fuel regularto pressure like to 5 psi and it turns on but mest up. i think the manifold need more air.

 

have you dyno your car?are you using hondata?crome?or etc.....

 

no and im using hondata s200

 

hondas need 45 to 50 psi of fuel presser

 

yeah i know but it wont start the manifold is not getting air because when i open the throttle and it gets air it star or if i disconnect the vacumm that goes to the brake buster

 

give me a call and i will explain it better. 760-791-5838

 

try adjusting your throttle cable i built an a fully built ls-vtec that i put in my friends car and we ran into he same issue......you need to turn your fuel pressure way up to like 45 psi and try holding the throttle open the smallest amount possible.....odds are it is somthing dumb like that.......you really need to find out what that motor is made of.....never buy a built engine without reciepts/papers the tolerances of a built engine can be very finnaky...... let me kno how that works u prolly need a vacuum block too

 

nope it didnt work it stays on but it sounds like ****. i think im going to need to take it to a shop.

 

is it tuned or anything? have you tried a stock/different ecu

 

no do think it may be the ecu

 

try a different ecu. just because its a S200 doesnt mean its running a map for that setup

 

compression test

 

i put a stock p28 and it turn on those anyone know if the hondata needs to be reprogram

 

did it run better with the p28? if so then yes the s200 needs to be tuned

 

the thing is hondata doesnt even turn my car on to do u know were can i take it so they can check if its burn

 

take it to a shop that has a dyno and tunes hondata
