Borg Warner S300SX 91-79 Turbo
Rated at 550-830hp
The S300X 91-79 is the byproduct of BorgWarner/Airwerks' engineering efforts to deliver massive boost performance with excellent fitment. This turbocharger is one of the highest power and fastest responding turbos that fits in a true street car with Air-Conditioning. This is the largest, most efficient and highest power T4 twinscroll turbocharger available in a midsize frame with a 4" inlet compressor housing.
It uses a 7-blade Extended Tip compressor wheel w/ 66mm inducer & 91mm exducer rated at 82lb/min. 4" Ported shroud Inlet, 3" outlet compressor housing. Turbine side is a 79mm inconel turbine wheel on a 4340 steel shaft. It uses a .91 A/R T4 twinscroll turbine housing, and can be easily converted to a singlescroll T4 .88 A/R by swapping the housing or ordering it as a single scroll.
Optimum for use in very high power street cars pushing 550-830whp that can not fit larger than a 4" inlet, certain AC compatible applications and twin turbo V6 or V8 non-AC engines. Journal Bearing and Oil Cooled only (watercooling and BB CHRA not applicable). WE RECOMMEND 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.
3AN oil feed line is recommended. If -4AN or larger is used, an oil restrictor is required (just like GT turbos)
Available with 90 degree compressor outlet
