When basic bolt ons won't do or you have simply stalled out with the performance of the factory turbo then PERRIN Rotated Turbo Systems are the place to go! With kits that range in power totals from 250WHP to more than 600WHP we have any boost junkies needs covered. PERRIN offer a range of turbos to fit a mild 2.0L engine, all the way to a crazy 2.5L wanting to break the 600WHP barrier.

The PERRIN Rotated Turbo kits include everything to bolt your turbo of choice to your properly tuned WRX/STI. The kits are designed to bolt to factory exhaust manifolds, and to factory cat-back exhaust. This allows the use of existing aftermarket headers, and cat-back exhaust systems to be used.
