Get a better turbo, precision sc61's are t3/t4's but have GT wheels. They don't cost much more than a t3/t4 too.Also an RB25 and vg30dett have the same size injectors.

I see, I have 50 Trim .63 A/R Turbine t3/t4 with internal wastegate. It's a standard garrett item. I had to have a new down pipe fabbed for it. I recently bought a turbonectics t3/t4 ball bearing turbo (suppsoed 62-1 comp)If i had to do it it over i'd get the SC61. They go for a little over $700.

You may need to use a spacer between the turbine flange and manifold.

I thought precisoin sc61's weren't all GT series? I thought it was like you can get a precision turbo the come standard polished, 360 degree thrust bearing, optional ball bearing 1 side, and optional wet center section?

the gt series turbos by garret is dual ball bearing wet center, internal/external of your choice?

They have GT wheels, not center sections but have options for ball bearing too. Not all GT series are ball bearing though, those that end with an R will be, ie GT30R.

I have an "SC61" It's an APG's version of it. Spool isn't that bad. At first I though it sucked but after some tuning and getting used to it I would accually like to go with either an .82 ar exhaust or a T4 hotside. I start to see boost around 3200 in 3rd 4th and 5th gears. I get full boost around 4K but the car really takes off around 4500 to 5000 RPMS.

No I never had that problem. I did have a problem with the PFC not working at all since the power battery + wire wasn't hooked up.
