Im not sure about $18K...Im doing a RB20DET into a 71 Z and so far my expenses are about 4.5K including the engine, intercooler, emanage, down pipe and "headers", engine mounts, and new gaskets and injectors...I still need to a 3" exhaust. Now saying that Im only including the price of engine install...no suspension or cost of car.... Oh ya I still need a fuel pump, boost gauge and and piping and a few odds and ends but with wise shopping that will be no probs. And yes the turbo will be stock....for now!
My old engine was a 280 turbo block bored and stroked to 3.1L with all the bells and whistles..mikunis, nissan motorsports parts etc and believe me its alot more expensive!!!!!!! And it runs like an SCCA racer....burps and farts at low speed and loud and fast as the RPMs grow! Best time I got with carbs on the quarter was 14.5sec at 98.9mph I cant wait to finish this install and drive the old gal.
