Turbo b16 problem

[MonKK]

I got a jdm OBD0 b16 in my 90 civic EF hatch. I just put a turbo kit on the car. Turbonetics t3/t4 turbo, dsm 450cc injectors. I took it around the block and it runs fine if I barely tap the gas. But when I want to gas it half way or more, it seems like the fuel just stop and the car just dies. Anyone have any suggestion on what the problem is?

Fuel pump?

hey man have u figured it out yet? i boosted my b16a ej1 today and does the same thing as yours...engine stalls at like 7,800rpm around there...let me know.

Sounds like you need a tune lol.

 

[dookiehatch]

defenitely lol...maybe fuel cut-off?

 

[bud6770]

Well you cant just throw on a turbo and expect it to run right lol, obviously you need to chip ur ecu and after that go to a good shop and get a tune, should run anywhere from 300-450. Its well worth it tho, until you get a tune dont go over like 4.5k rpm's unless you wanna blow ur s**t up

My ecu is chipped for my mods. I'm guessing it would be a fuel problem. Fuel pump maybe or bad injectors. Other wise would be spark plugs somehow.

mine did the same thing and it was the map sensor but you say you have your ecu chipped. any error codes?

 

[dookiehatch]

i have a missing link, but cant figure out how to install it...my throttle body is weird....its not bolted to the t. body...instead it just hangs there with a little vacuum hose goin to it and the wire harness...would i have to bolt it to the map sensor and run a vacuum hose from under the missing link, would this help so the engine does not stall anymore? thanks.

Fuel.

My bet your ecu or "modded" ecu isn't "modded" for fuel.
I would suggest seeing a local tuner before you lean her' out and before it goes... "POP"

what basemap is the ecu running on?

Yeah, double check yur spark plugs(make sure there the ones you need for setup,make sure the gap is correct too). At what boost pressure is it cutting out at? if you figured it out already let me know how you make out, im boosting my b this summer too. im curious, thanx

 

[MonKK]

ECU i'm running is the OBD0 PW0 ecu for b16. Spark plugs are gap at .030.

wat injectors do you have?

 

[MonKK]

450cc DSM injectors. Fits perfectly. But there is only thing, one of the injector is crack on the tip. But i'm guessing that shouldn't matter but I will go try a new injector to see if it does the same thing.

you're probably guessing wrong.

 

[MonKK]

Nope still does the same thing. except runs a lil smoother. And I am wasting a whole Shyt load of gas.

 

[Shiznit]

ya it doesnt matter that the pintle cap is cracked. i think you should stick that missing link on and see if thats your problem. if it fixes it then get a 3-bar map sensor and take that POS missing link off

walbro 255 in tank fuel pump

buy a walbro 255 in tank fuel pump for 100 shipped. maybe a "fmu" fuel management unit..

 

[MonKK]

Damn that means gots to drop the fuel tank to replace the fuel pump. O wellz start on it this weekend. Another problem is when my idle starts to bounce from like 1k rpm to 1.3k rpm, I can't even drive it because when I gas it even a lil it will fuel cut but when I shut off the car and turn it back on it will get fix. TPS or MAP sensor problem? Also, On my old OBD0 b16 header, It had TWO O2 sensor and the downpipe I have right now has only one slot for O2 sensor, So which one would I use? The yellow plug or the green plug O2 Sensor.
