I have new Y hoses but suspect my orific hole is wrong size. I'm also pretty sure that my wastegate solenoid is bad because I'm overboosting like made until I block off the line leading to it with a nail. If anyone has these parts new, please contact me either here or at [email protected]

It's all in the orifice. I could be wrong, and don't quote, but I believe the opening is supposed to be .045. Check me on that. This more than likely is the problem..

I just recently had my wastegate actuator and solenoid replaced...also got new vacuum hoses and car runs perfect...I was overboosting just like u when I plugged that hole up...so much powa now! I ordered mine from Poston's since I ordered all new exhaust from them at the same time.

Here you go (love that search feature)!

If the link doesn't work, they mention. .043, .048, ..050. You should be able to find a drill bit very near that size. (or a hot nail)
