"Y" tubing!!!! Part# needed

[cesarp]

What is the correct GM part# for the "Y" restrictor that goes in the turbo (wastegate actuator). I want to make sure I have the correct one.

This if on a 84 T-Type.

Thanks.

Well mine's white so I'm gonna guess its been replaced with a regulat Y . If the parts departemnt at the local GM dealer is open at all tomorrow (doubtfull), gonna go mess with em with this one.

will this part# work for the 84 T-Type because that is for the 87 ?

I am never going to the local GM dealer again.............they have converted their parts department into a shrine of nascar hats, $15 matchbox cars, and $400 models of Dale Earnheart's engine. Not even a computer or microfilm viewer..........all that is somewhere way in the back out of view. I told the guy I needed a part for the vaccum system on an 84 buick grand national..........explained to him what it was..........which line it was on.........and he went on his way into the back. About 15 min later he comes back with a printout of a 2 barrel 3.8 engine telling me he can't find what I am asking for. I explain the engine is a 3.8 but it is a s.f.i. turbo engine...........to posibly look under regal/t-type..........back he goes again. Bout a half hour later he returns with a printout of a 86 turbo engine and says this is all they show............nothing else. I need to try another dealer

Guys

I put this Y hose on my car and it listed on an 84-85 GN. I saw the exploded digram myself at the GM dealer.

I used it all last year and it worked no problem.

25518438 is what I show in my parts book for 84-85 Restrictor, and I think it may be a .050 ( fifty thousandths ) orffice.
I beleive I read somewhere that the 87's are more near a .040 orffice, and the the TTA is .035.

you CAN just drill the newer 25525576 out WITH A .050 bit or punch ream it through with a ROUND feeler gauge.

I use a DELTROL easy read needle valve for an ADJUSTABLE ORFFICE< it is only about twenty bucks from the valve store online ordering, has 1/8" npt female fittings, and GIVES YOU FINE TUNNING TWEEKING ability to adjust boost, JUST PLUMB it in between a regular unrestricted tee or Y from the pressure output fitting port on the turbo to the wastgate actuator and solenoid vent.

GOOD LUCK AND REGARDS

Talked to a few BUICK dealer's today....out of production.....was told on a parts search, no one locally, nationally, or inter-nationally has it. 100% unavailable

Go take a look at johnsperformance.com . I think they make furnace gas orifices this size I can fit in a vaccuum Y . Dunno, gonna check at home depot
