Budget is low but I'm saving to put my into my nx2000.. and when I'm finished with it I want like 250 HP?? Not sure into wanna do NA or turboed And not really looking for running it down the track mostly auto crossing it. And I can do a bit of mechanics I can swap engines but not to much more then that but i do all my own work on my cars.
DET for the exact reasons @ny5speed quoted you, sir.
Find a stock SR20DET engine from a Bluebird or Avenir. Swap that into the car, get a DET ECU if you wish, an intercooler and piping, and a DET MAF and go to town.
