Our current cartridge turbo upgrade the SPE750 has proven great power results without sacrificing any low end response. This package has been tested by not only Jay Leno, but customers worldwide. Our SPE750 has been tested on our "R" package which produced over 790 AWHP using C16 or E85 on a 3.8L VR38DETT.

SPE750 Turbocharger

SP Engineering has now developed our SPE950 which houses a Garrett GTX center cartridge providing over 950 AWHP using our engine package. The GTX-R turbocharger features a forged machined billet compressor wheel which will provide higher flow and response throughout the entire power band.
