Block/head combo for turbo swap
Whats up everbody, its been awhile, Ive been busy securing cars. Heres the deal, I finally scored a 82 ZXT, and a 75(N42, got hit) and a 77(N47, body donor) 280. So the game plan is to put the turbo into the 77. But I want to drop the compression(is that right? low comp=turbo, high comp=N/A). I'm thinking about keeping the F54/P90 combo but considering swaping the dished pistons from the N47 to the F54. Or should I just put the P90 on the N47 bottom end. It will get intercooled, bigger injectors, turbo yada, yada. I figured the more fuel/air I can fit in the cylinders the better

yeah get a an IC and exhaust made up, then you can get a new fuel rail with w/e injectors you want, after that you gotta find a better way to tune it. up the boost some and you may have to change the headgasket to a metal one depending on how much boost you wanna run but thats no big.

Thanks guys, figured it would be easier to run the stock set up with a few bells and whistles. Totally forgot the weight is already gonna play a big factor as well. Do some of the Supra injectors swap in or not? Thanks for the advice, much appreaciated!!

The factory ECU is set for a certain size of injector. It will not lean your fuel mixture out based soley on the O2 sensor.
The short answer is, don't up the size of the injector without a programable computer that can use those bigger injectors. You'll be running rich 99% of the time.

RX7 supra and DSM injectors are all the same 11mm injectors low impedence, so i dont think they will even work on the stock injector plugs with out resistor packs or w/e they are and are much bigger, DSM are 450's stock out of 1G AWD manual, auto's are like 350cc. and yeha they will all run to rich the easiest way to get tehm to run in your favor or at least the cheapes is an SAFC
