I'm planning on useing a stock 1981 thru 1983 wiring harness and Nistune on a fairly stock engine( 60mm TB, .57 trim turbo,41mm wastgate, 12x8x4 intercooler, Z31dist,2mm head gasket). I'v heard the stock harness is slightly better on the 81, is this true? will it matter with the Nistune?
Any thoughts for injectors-fuel rail for this setup? how much boost would I have to run to get 275 to 300hp(my goal)?
WAADaya think?
