Based on the Garrett GT BB design of the GT2854R, this kit offers a bolt on solution with all the parts necessary for installation on a Z32. Z1 has invested in having all of the brackets, flanges, adapters, and fittings mass produced in order to provide you with an economical trouble free bolt on solution.  The Z1 GT555R kit uses the same off the shelf Garrett turbos as the JWT Sport 550BB kit.   Great response and reliability from the new Garrett GT BB cartridge with max power potential of in excess of 550 rwhp with appropriate modifications, race fuel, and tuning. 450 whp to 550 whp is typical for pump gas.

Applications using aftermarket exhaust manifolds that mount the turbo down lower, may require light shaving of the left side motor mount bracket in order to clear the compressor inlet pipe, as seen HERE. For those that prefer not to perform this relatively simple modification themselves, we do offer the LH motor mount bracket pre-modified as an option below.
