Pte 6262BB won't spool on 2.0L block.
 

Hey, Car was on the Dyno yesterday, and we couldn't get the turbo to spool. It would hit full boost (17Psi) at 7500rpm and at 3000rpm -200 Trq

We did boost leak, compression, leak down... all the tests were properly done..

Anyone have and idea ? So far, Ive been told my injectors are to big 1425 for 94oct. and my GSC S2 cams might be an issue also..

Please help me out guy's

Thanks

have you checked the condition of the turbo? perhaps it is blown. an smoke at WOT or in/out shaft play?

Sounds more like a turbo issue. Take the turbo off and check compressor and turbine blades.

It is for sure not the cams and those injectors should have no problems on pump gas. It's most likely a problem with the turbo or wastegate. Is the wastegate stuck open? Is there any strange noise or smoke while the turbo is spooling? Will the car idle and cruise correctly?

sounds like a wastegate/boost controller issue.

Turbo is brand new... no issues. Wastegate is unplugged ... plz keep sending ideas guys,

The Grimmspeed boost controller is unplugged therefore running wastegate pressure?

^ and that would make about 17 psi

yes

sounds like a winner,check and see if you have the 17psi spring in the WG and if so,you know that's what's up.

but then why would only hit full boost at 7500rpm ?

Wastegate or BOV bleeding off air is my guess.

Pull your wastegate outlet/dump and see if the valve is stuck open. If you have a dump tube, I usually undue it then use a mirror and flashlight to look at the valve. I use a bicycle pump with a gauge to pressure the lower port on the wastegate to ensure it is opening at the proper pressure and doing it smoothly.

Are you running a catalytic converter that could be clogged/broken?

bang, right on the kisser!

If that all checks out ok then check that you don't have any rags or newspaper stuffed in your intercooler piping from when the car was taken apart. I've seen that happen before, found it in the intercooler inet.
