7670 T3 IWG B-Type Turbocharger (375-650HP) By Borgwarner

EFR 7670 is ideal for road racing and time attack applications, as well as responsive high power street driven vehicles. Engineered for great spool, quick response and the potential to surpass 640hp - the 7670 is capable of 64lb/min compressor flow - unheard of for this size compressor wheel. The 7670 is an excellent turbocharger for road racing and time attack applications, as well as responsive high power street driven vehicles.

The 70mm Gamma-Ti turbine wheel is the optimal match for the 57.2mm inducer / 76mm exducer FMW compressor wheel and is capable of 45+psi boost. This turbo uses the mid-size EFR ported-shroud compressor housing, great for fitment in cramped engine bays. Ideal for use in single turbo applications for the 375-650hp range, or as twin turbo applications 800-1200+hp. Ceramic Ball Bearing only, watercooling recommended (not mandatory)

A fittment pain worth having.

Bought this baby for my 92x and even though not forced up yet it's a thing you can hang in your man cave and enjoy. But that's not what am all about it will be under that 92xs hood. As the picture will suggest custom up and down pipe is a must I insisted to creep out as low as possible unlike other not so sweet looking rotated kits. It won't be long now before I can post some all done pics before any numbers. I upgraded the plastic BOV cover to a billet one and customer painted the compressor and the turbine stainless cover. The green brown looking color is a jet hot 2500° coating didnt want to hide the beauty with a blanket. The red is a power coat.Definately will be back to update.
