The S300X 83-75 is quite possibly the best value in today's high performance street-turbo marketplace. The 83-75 has an ultra-high flow 68 lb/min 7 blade extended-tip compressor wheel and a 10 blade 75mm inconel turbine wheel with 4340 shaft. Recommended for use in quick spooling 500-680+whp applications, this is an excellent turbo for a very fast 4cyl street car. It uses a 7-bladed Extended-Tip compressor wheel w/ 60mm inducer & 83mm exducer. 4" inlet compressor housing with 3" outlet. Comes with a .91 A/R Twinscroll T4 hsg standard but upgrading to a 1.00 a/r T4 Twinscroll housing is recommended! .88 A/R T4 Singlescroll also available for undivided applications. This compressor moves more air than a 61mm GT3582R but with only a 60mm inducer compressor wheel to keep inertia low. Capable of efficiently pumping up to 45+ psi boost, this turbo generates big torque numbers. Journal Bearing and Oil Cooled only (watercooling and BB CHRA not applicable). Similar to a twinscroll GT35R with higher boost capabilities at a lower price. FULL RACE RECOMMENDS MODIFYING THE TURBINE HOUSING TO 3" VBAND. (this allows for fitment identical to 40R, letting you swap between any t4 turbocharger with 3" vband outlet and guarantees perfect fitment to Full-Race turbo kits)
This dynoplot compares the BW/Airwerks S300SX 83-75 1.00 A/R to the Twinscroll Garrett GT35R 1.06 A/R
Full-Race Recommends machining the BW/Airwerks turbocharger outlet and welding on a 3" Vband flange in the garrett 40R location. This allows the BW/Airwerks turbo to bolt up to ANY aftermarket twinscroll T4 that would normally fit a T04Z, GT40R, T66, etc.
