bucking on turbo'd y8

JK19 · 09-27-2009, 02:28 PM

ok searched and found 1 thread that was "kind of" like my problem and everyone said get a tune but heres the problem.

I put a turbo set up on my 96 ek coupe with a d16y8. boosting 6psi. i have colder spark plugs(NGK bkr7e's). now it started fine, idled great. took it for a test drive hit 3500 got to full boost then i let off. all of a sudden when i go to let out the clutch it would buck and jerk and almost die. I had to rev it up to about 4K and let out the clutch every time to make it back and I constantly had to push in the clutch cuz the rpms would drop. when i popped my hood the turbo was smoking...

I know for a fact its getting oil(it may not have been enough tho)
my tank is half full with 87 I know i should run 93 I knew it would run like crap but i didn't think it would be THAT bad.
and my spark plug gap is at .028 someone said that was good for boost(was i misinformed?)

EDIT:Found out the problem. my spark plug gap was WAY to small .028 was not correct. I changed them to about .048 and fixed my vacuum lines made a mistake runs good now no problems. thanks for all the help guys.

it sounds like you are hitting fuel cut but the turbo is smoking what size oil line u hae goin to the turbo might have blown the seals?

its a normal size feed line its the same size as the one on my boys turboed bubble so I know the feed line is good I think the oil restricter might not be letting enough oil in, and my return line is huge. but if I blown the seals wouldnt it leak oil into the exhaust and intercooler piping?

not real good with turbos but if you blew a seal pull ur intercooler piping and see if you have oil in there does the car smoke when u drive it ?

not really I'm running open down pipe right now so I can't really see it cuz when im idling and look under there is no smoke.

honestly right now im leaning towards the spark plug gap and the gas. until others chime in and tell me what they should be, I'm kinda thinking thats the problem(lol hopefully...easy/cheap fix)
