Precision SC50 Turbo April 04, 2007, 09:14:45 PM I'm looking at one of these for my '87. Is this a good turbo for my application? It has a 50mm, 50 trim compressor wheel with a 2.123" inducer and a 3.000" exducer. It has a T04E style compressor cover with a billet aluminum backplate. The turbine wheel is a T31 76 trim with a 2.559" inducer and a 2.228" exducer. The center section uses the upgraded 360-degree thrust bearing, which lasts much longer than the standard 270-degree bearing found in most low priced and/or off s turbochargers. The exhaust housing is a Precision Turbo casting with a T3 inlet , 5-bolt discharge for the downpipe and a 0.48 A/R for quick spooling.Let me know what you guys think. Thanks! Quote Selected

Precision SC50 Turbo Reply #2 – April 05, 2007, 12:58:33 AM The .48 SC50 is good for stock-ish motors. Layla has had the ball-bearing SC50R for 18 months with the .63 SIII housing/wheel and even with a heavily modified engine it spools a little on the slow side. Quote Selected
Precision SC50 Turbo Reply #3 – April 05, 2007, 09:33:13 AM IMO you should probably worry about maxing out a stock T3 before you worry about stepping up to a bigger turbo.I recently bought a 57 trim, and even with everything I've got done, it's too much for what I have right now. It his full boost around 3500 RPM, but doesn't really start pulling until 4000+ RPM.Considering that you're working off a stock head, stick with a T3 for now. Quote Selected
Precision SC50 Turbo Reply #4 – April 05, 2007, 04:51:07 PM I run the same turbo, but in a .63 A/R.My car is very mild, run a Bobs log header, the SC50, full 3" exhaust, cold air intake, ranger roller, race engineering cam pulley, and 20psi of boost.I love it. Quote Selected
