wastegate

[jerrad]

i have my boost at 24#s but when the car is starting to shift it slowly starts to lose boost until it ****s then it starts the process over. would a new waste gate cure this? thanks jerrad

Do you have the stock WG that is a 13# spring or a Heavy Duty WG actuator with an 18# spring? I would guess that a strong spring WG actuator will help solve it because it sounds like the WG flapper is being blown open releasing the boost prematurely.

im not sure it had it when i bought it. can i buy just the spring or do i have to get the whole wastegate? where should i get one from? thanks jerrad

Have to buy the whole assembly, wastegate actuator. Most vendors sell these, PT&E has them for $79 and they have the HD 18# ones if you run 24# all the time with alky or something, this is probably what you would want...just be careful if you don't have race gas or alky otherwise sometime.

Also, be sure your "Y" orifice is setup correctly in the vac tube from solenoid to turbo and actuator....straight side goes to turbo compressor housing. I've switched these on mine and had no effect, but others have found an effect...it keeps the full boost pressure from being at the solenoid, but functionally should do the same job, just don't know if full boost all the time will hurt the solenoid.

thanks for the relpy and i always run the alky (its such a nasty habit)
