So... I am about to begin building a VG33ET for my '85 2+2. I am a professional mechanic, so I am well versed on how to actually perform the work, but I have been unable to find the answers to a few questions before I get started. The overview is I have a VG33E from a late '90s Pathfinder, and I plan on using my stock VG30E to supply the crankshaft, camshafts, and accessories. I will be using a new VG30E oil pump, as well as all the VG30E pulleys (see below) and accessories (alternator, water pump, etc.). Now to the questions...
1. Did Nissan use the same crank pulley between the Turbo and NA versions from 1987+? I have done some research, and according to courtesyparts.com, Nissan only had one part number (12303-21V10) available for any 300ZX, whether Turbo or not, after 04/87. If this is the case, that means I can run this crank pulley in lieu of having a true '84 - '86 Turbo crank pulley? Obviously I would use an '87+ alternator, as I believe the only difference between the crank pulleys to begin with is the water pump and alternator belt. I also checked with 300zxparts4you.com, and he seems to have the same consensus, but I want clarification before I buy one. The main reason I ask is because locating a factory Turbo crank pulley seems to be ridiculous, and I have no availability on a true VG30ET to scavenge parts off of.
2. Turbo manifold. I know the '84 Turbo came with an air-cooled T3, the '85 - '86 Turbo came with a water-cooled T3, and the '87+ Turbo came with a water-cooled T25. Forgive me, but I am a novice when it comes to turbo flanges. I plan on running a T25 turbo on my VG33, so does this mean I specifically need a turbo manifold from an '87+ model?
