TURBO PROBLEM

[mk3_supra]

Didn't get an answer in the other thread so here it is again.

Just got an 89 turbo supra turbo was working fine for a while. But after my clutch burnt out i noticed i wasnt hitting boost i'd just floor it and nothing. When i drove it before i would start to hear this high pitch whistle but now its gone any help?

Have you checked for boost leaks. Can you hear the turbo spool up? Is it smoking at all? Do you have an accurate boost gauge? What does it show?

^ What he said. Also, take the accoridan hose off, and check to make sure the shaft spins.

Take your bov off. Blow through it. If you can blow through it, its toast.

ummm when i started it in the morning when i first noticed the problem it would hit boost then after a while it won't even hit that high pitch whine anymore. No boost gauge doesnt go up i dont feel any extra power even when i've got it at 6ks...

Take the intake hose off and check for play.

hmmm I think I figured out what caused the problem
haha the supra was my first turbo car and that was my first year driving
when I'd gun it down the high ways and i see my turn coming up
I'd be going 5500 in 5th and I'd just drop it in neutral and coast to the red light... anyways I'm planning on buying that baby back around summer hopefully original owner did some work on her

no coast for about 10 blocks in neutral at 5500 then come to a stop
I know it was stupid but I'm guessing throttle closed turbo still goin=bad?

 

[mk3_supra]

again that was the first time I drove stick+turbo =( I noob'd up

How in the hell to you just coast 10 blocks from going 5500 RPMs in 5th gear? And you left us hanging by not telling us what the problem was...

I read this year old thread and im still lost:3d_frown:

 

[starscream5000]

FYI 5500 RPMs in 5th gear with your year, tranny, and diff is almost 140 MPH with stock sized tires. Coast just 10 blocks? I don't buy it.

noob'd up again that wasn't it sorry guys and haha I guess 55K is a bit of an exageration 3-4K in 5th iunno that was a year ago
