Ok it is possible to just mount the modifide engine, tranny, and driff and use the factory wiring just change the ECU of thr N/A for the turbo...? There is a friend that want to race with me when I put all together he has a sr20T 240sx... Do you have any advice? Plus I'm not worry about the diff or changing the engine I know that it will fit, including the tranny but I'm worry on the wirring and ECU the sender unit of the N/A of the fuel pump will it be the same part as the turbo? will the volt gauge will funtion? By putting bigger pistons wil I be having a weak bolck?
