Evo 7 8 9 T4 Twin Scroll Turbo Kit

  • 5,19999

Starting with the head flange, we use CNC billet 1/2" flanges for a strong, consistent and smooth transition into the runners from the head. From there, the exhaust travels through 316L stainless steel weld els that have been back purged with full penetration welding. While using our unique welding techniques, we are able to get full penetration, single pass welds while minimizing heat input to prevent warping of any of the flanges. Each port runner, vband outlet, and wastegate outlet are all ported for smooth transitions and proper boost control to prevent boost creep. 

Fitting the large frame EFR turbocharges on a 4G63 is no easy task, and the install of the larger frame turbos does require some trimming. There is a tab on the transmission that must be ground down (non structural) and the corner of the OEM front transmission mount must be trimmed off. This kit must be used with an Evo 6 style radiator, and slim fan. This kit will work with Mishimoto and Koyo racing radiators. Thicker radiators may need custom brackets made for the radiator slim fan on the 8374 and up turbos.

  • Borg Warner T4TS EFR Turbo (7670, 8374, 9174, 9180)
