Hey whats up...
Just bought a 91 240sx, will def have some questions lol as I will be doing a manual swap, building the motor and turboing the hell outta it lol....not new to boost tho I have a 2001 supercharged Cavalier...pretty quick little thing can keep up with slightly modded SR's.....

 

welcome to the forums

 

sounds like your on the right road to speed....i recently did a motor swap, i swapped the ka24de with the rb20det, from auto to manual...post if you need more info or have problems

 

Good stuff, hopefully i'll be one my way soon also
