Here are the specs for my 86T:
86 300ZXT -- 87+ front end conversion and SS front spoiler, maxima intake with 370CC injectors, chipped ecu (now with expanded maps up to 7200rpm and increased load range), full T4 turbo, external wastegate, Z32 MAF, BOV, 944T intercooler, 3 inch mandrel bent exhaust, walbro HP fuel pump, 88T LSD, FS5R30A with short shifter, ACT S/S clutch, ACT HD pressure plate, Fidanza flywheel. ST springs, tokico illuminas and poly bushings. Schneider cams (280/270, part# 17076 with schneider valve springs). Port and polished cylinder heads/intake manifold. External Oil Cooler.
I'm going to get new injectors (550's or so) and the T4 turbo that I've got is probably not going on. The specs on it are: p-trim .81 a/r, 50-trim .63 a/r. I bought this turbo off of ebay a long time ago and it WAS NOT WHAT WAS IN THE AUCTION. I dont even want to tell all of the problems with this thing (custom machined turbine housing, had to modify exh. manifold to accect T4 turbo etc..) and on top of all this, I can't even trust that it was rebuilt properly.
Criteria for turbo selection:
350-450hp (I guess I'm governed by the stock pistons)
7000-7500 RPM (max)
Prefer to use T3 exhaust manifold... but I guess I could do T4
Thinking about a T61 with a T3 turbine housing (compressor map seems to be real nice, IN MY OPINION superior to the 60-1)
So my questions are: what a/r on the hot side? Stage 3 or stage 5? Is watercooled center section a must?
OR - other suggestions on turbo selection?
Jason - how do you like the GT35? Anyone else running one? Any dyno graphs?
