if there are certain things you want me to take a pick of just let me know

[BMWZ318is]

one thing that is also different from the last time i had it running is im using the stock exhaust manifold gasket before i was using the one they sent with the turbo mani

[Mr. Burns]

well now...thats a nice and clean setup for sure.

I would start simple in that case...

open BOV/wastegate?

vac leaks?

nothing obvious jumps out to me...

[ak-]

I skimmed over the thread and just read this;

My boost gauge doesnt show boost but it will show vacuum. all the pipes are connected nice and tight. and one of my friends suggested that i change it to see if it would read differently.

This, leads to this:

its a t3/t4 .60 a/r its an ebay turbo

I'm willing to bet your turbo is blown.
Ebay turbo's are hit and miss. Took a friend 2 weeks to blow his, and another 1 year.
There is also a thread on here with some dude in a bronzit running one for 2 years lol.

I have eBay turbo. The guy before me used it for a year, and I almost have a year on it now. So that's about 2 years, and I have a bronzit. I know they guy you're thinking of though ^^^


Good luck finding the problem!

[kamotors]

setup is a lot cleaner and simpler than I had envisioned. only thing I can think of is a dead turbo, BOV constantly leaking air, wastegate open. If your boost gauge is showing vacuum its all good its just the fact that your simply not making boost.

is the gauge getting close to zero under load?

[Mr. Burns]

running ebay turbo here too.

.60AR CX Racing whatever the generic chinabrand is...

over 1 year no issues...

but I wouldn't rule out blown turbo.

certainly you would not of installed it with a grinding wheel etc

[blueapplesoda]

Wastegate stuck open? Do you have its vacuum lines plumbed correctly? Have you got a new boost gauge? they sell them at pepboys...just grab one and return it when you are done.

The turbo is such a simple device I don't know how it could be bad...but don't rule it out

[BMWZ318is]

i tested the wastgate and its functioning properly and yes the gauge will go up to zero but wont go past zero thats under a load while im driving. If the turbo is spooling and the BOV is releasing pressure when i let off the throttle could the turbo still be blown. im running an i head on an e block could that be an issue?

[einstein57]

Those T3 gaskets suck. I've blown them out in a week. Would be hard to hear the leak with an open down pipe.

[BMWZ318is]

thats true and ive reused my turbo gasket like 3 times ha ha

[TS87325IS]

Sounds like an exhaust leak inbetween the head and the turbo or the waste gate is stuck open, or an intake leak on a charge pipe. Thats the only things that come to mind. Its a head scratcher for sure :-)

[BMWZ318is]

could it be a mix that my boost gauge doesnt work and im making boost but im not feeling it hit boost cause my tune sucks

You should get a wideband before you go on.
