I am currently in the very early stages of a ~300hp L28ET build and am just trying to feel out what I want to put behind it. The car is 73 240z and had an L24 with an auto in it and barely ran, so I barely have any seat time in an S30. I know very little about the cars history so I am not sure if it was originally an auto car.
When I bought the car it came with, what I have detemined is a 4 speed in the trunk. So far, I havenˋt opened the rear end to figure out what gear ratio that I have.
I have been doing the research on the options, but know very liitle about the hp/
