GenTT
Intercooled Twin Turbocharger Kit for GM VT-VZ and Pontiac GTO

Gen-TT dominates the twin turbocharger market for LS1 and LS2 powered GM cars, being designed as a straight bolt on fitment for all Holden Commodore based, Sedan, Utility, Coupe (including US GTO), and all wheel drive vehicles. Providing up to 700hp of seamless boost from its twin KKR330 turbochargers, and feeding the engine with super cool air via the fitment of a large front mount intercooler, Gen-TT represents the very best value complete twin turbocharger kit currently available for the L series GM engines.

Answering the call for more top-end horsepower to give even more impressive dyno figures and trap speeds, Gen-TTR; a larger turbocharger equipped kit is available. Built on the same successful platform as the Gen-TT kit, the TTR is matched to higher output forged internal or stroker engines being able to push over 15psi of boost pressure and with the potential to generate over 850hp from its twin 480 horsepower compressors. Great news is that the Gen-TTR turbochargers sit in exactly the same place as those on the Gen-TT kit which makes an upgrade for power hungry Gen-TT customers a simple conversion. This is a genuine 9 second quarter mile capable combination, but due to the tuneable nature of a twin turbocharger system it still delivers the excellent driveability and everyday street manners of the original Gen-TT kit.

Note: Pictured (below right) is a side by side comparison between the existing Gen-TTR (left) and Gen-TT (right) which shows that the extra power offered by the TTR kit is due to a much larger compressor wheel being used which in turn will flow far greater amounts of air.
