Hey I got a great deal on this SS downpipe for the stock t3. Its made to bolt up to the stock turbo with the wastegate housing removed. As of now Id just have to find an external wastegate, which I could pick up for around $120-150 locally used.
My other option is to just use the stock internal wastegate. I have all the parts needed and ready to go.
My question is should I stay with the external and the above downpipe or just use the stock internal wastegate. From my research Ive found the above setup will start to cause boost creap at higher boost because of the size of the opening on the turbo. My motor will only be running around 12 psi, and if I ever wanted to go higher Id move to a different turbo (different downpipe). Im assuming 12 psi wont be to high of boost for this to be efficient, but is it worth the money (cost of wastegate) to have a externally wastegated system?
So ultimately, I have the money to get a external wastegate but it would just mean it will take a bit longer to get the motor in the car. Is sit worth it, or should I just sell the downpipe and make a few bucks?
Thanks!
