^ a bone stock KA24DE (FWD) will take 300fwhp. the ringlands will blow in acouple of months though. thats the weakest part about the KA motor. the ringlands. get forget pistons, and you could run some boost. In the RWD KA community, people have run up to 15psi on stock block, some last some dont. With a good tune, proper TIMING, you could easily make 250whp. I would recommend a fuel pump and injectors....
