Garage Tuning's Twin Scroll turbo kit is the ultimate in Subaru turbo technology. Twin scroll turbos provide more efficient turbo spool with higher power output than conventional turbos. All of our piping and flanges are 304 stainless steel, tig welded in our very own shop, right here in Southern California. Our flanges are the highest quality available. Half inch thick stainless steel guarantees our kit will be leak free for a lifetime.

When it comes to turbos, nobody beats a Garrett. Garrett GT series turbos don't have seals like other turbos. This allows them to spool up faster than any other available turbo. This also means that the turbo must be parallel with the ground to prevent leaking oil and ensure faster spooling. The Garage Tuning kit makes no compromises on turbo placement just for bolt on front mount compatability. We believe that going the extra mile for smooth airflow pays off on turbo response and peak power. Our headers, up pipe and downpipe are as smooth and straight as possible. Our headers have plenty of clearance for aftermarket oil pans like the Moroso pan allowing you to add much needed oil capacity for road racing.

Currently, we offer the GT30/35R turbos in .82 and 1.06 ARs. We also build at T4 flanged up pipe for GT40+ sized turbos. These kits include an untrimmed and unfinished downpipe with all of the needed parts to build your own downpipe for your custom application.

All kits have an O2 sensor bung placed at the top of the downpipe for your front O2 sensor. There is no second O2 sensor bung included. The factory ecu uses the second sensor to verify that the catalitic converters are functioning properly.

Track, drag or street, all racers will agree that the Garage Tuning Twin Scroll Turbo Kit is the most responsive and affordable twin scroll kit you can buy.
