The circumstances are too long to list in this thread.. The main point is that i need to make a custom wastegate spring, or find one for sale that will run around 3 pounds. ( I need to run a T04S04 on stock injectors). The wastegate is a trust 47mm. Just wondering if anyone has seen small springs for this size wastegate, or anyone has successfully run a custom made spring before.

i bet even if you left it open all the time it would still do over 3psi.



stock ecu or aftermarket? if its not a stock ecu, i bet you could run 8-10psi

Well I can't leave it open all the time (noise issues). I have a power fc, but 8-10 psi is no where near possible with stock injectors....Just wondering if anyone has had success making a custom spring before.

Tial w/gs have several springs, one of them is 3psi or near that I believe...
