This turbocharger is a 90% bolt-on experience for any performance Z31. Not only does it fit in the factory location, it provides the added benefit of modern turbocharger technology, the accompanying power boost that comes with it, as well as a lightweight, compact package.

FITMENT NOTES:

• Has not been tested with A/C equipped vehicles

• Requires fabricating your own 2.5” downpipe. 3” is too large to fit around the steering shaft

• For customers wanting to run an intake to the turbo, you will need RevShift engine mounts to add additional clearance around the engine mount bracket for a pipe and filter. Or you can run a Turbo-Guard.

• Further fitment details can be found HERE
