The new EQT Vortex is a complete bolt-on turbo that is manufactured with all brand new components. The housings are modeled after the OEM IS38 turbocharger for proper fitment, but they are all brand new and original castings made and machined for the specific wheels we use. The turbine is a TD06SL2 wheel measuring at 61mm/54mm with an 8cm housing. The compressor is a custom billet wheel measuring at 53mm/71mm. The entire turbo is manufactured, assembled, and precision balanced in a state of the art facility. The EQT Vortex is good for 450whp on pump gas and over 500whp on race gas or E85. Note that upgraded high pressure and low pressure fuel pumps are recommended to take full advantage of this turbo.
