i vaigly remember some one posting about the 300 somthing hp ka24de thats NA thats built for the nissan mud trucks that they race i tried to search for it here, and on google, i was wondering if anyone remembers this as well.. i just wanted to see what tehy did so special for that kinda power NA

 

that is more than likely a very non-streetable engine. and on top of that a very costly engine. if you crunch the numbers maybe getting 230rwhp is about 1500-3000 depending on what you use. and getting another 70 on top of that is even more. because the price above is just about everything i can think of doing to a KA.
