I need some sugestions on moding a stock L28et with a P90a head out of a 83 280zx turbo with t tops and a 5 speed. Trying to get someware between 300hp and 400hp for a street ride. I have had the head port and polished, block cleened and honed at the standard bore. I have a t3t4 turbo with intercoller kit instaled. I am planing to convert the fuel injectors to 14mm and find a new fuel rail. Need to find some forged pistons and decide on stock or aftermarket rods. Big decision on which stand alone EMS to go with. Any sugestions would be apriciated, this is my first turbo build.
