Is the compressor trim of the 617 the same as the 603 or is it a standard T3 which is less? 55 trim for the 3.5L, 50 trim for the 603 and ? for the 617.

I want to replace the bigger turbo I have because it has been a nightmare. First 3 lasted a week each. This one they built is lasting but the wastegate is not working. It must be just a crack open because I can get 20psi but no more. Not that I want anymore but the wastegate actuator does not even have a pressure line to it.

It is a borg warner product. The car does run quite nice but I want everything to function properly and who knows how long this one will last. It is on about 2 months now.

I am taking matters into my own hands and I want to build a kkk or garrett that will match my fuel delivery. I have a custom chip that has maxed out my ip delivery at full throttle. I believe I have 6mm elements compared to the 5.5mm elements in the 603 pump.

I was thinking a T3/T4 hybrid but I am not sure what size compressor wheel and turbine wheel I ought to use?

Also what is a comparable KKK product trim?
