This winning combination results in the best all around turbo kit for Z32s over 500 whp, at a great price!  Will produce 28psi and can make 600+ whp on race fuel with proper tuning and appropriate modifications.  These turbos feature all new components; high output compressor, high-efficiency GT series turbine and compressor wheels.  Comes with flange adapters and couplers for a bolt-on setup to stock pipes. 5 bolt downpipes are required and available as an option below.

With the addition of camshafts, intercoolers, portwork, upgraded manifolds, and proper tuning abilities, these turbos are capable of producing up to 700 whp. We've always been impressed with the performance of the HKS 2530s now you can purchase almost identical turbos built by the same manufacturer (Garrett) for over a thousand dollars less!
