Hey Gore, nice deal. I just paid $2000 for my 93 240sx with 140,000 on it, BUT SHES BEAUTIFUL!!
Anyway Dareo, it sounds like you might want to reconsider that KA if you're not prepared to do the rebuild yourself. If you want to realisticly hit 300-400 hp, you're talking about an assload of bolt-ons. ANd I mean an ASSLOAD.
Why not swap that old KA for some thing a little closer to your goal? I'll admit I don't know all the prices out there off the top of my head, but a serious rebuild on a block alone(forged pistons, shotpeened rods, moly-coated crank, full balance and blueprint, etc...Not to mention the labor charge anal-rape by which ever shop does it for you...) can more than pay for a whole SR-20, and put you within close range to afford an RB25det. After you have the head ported on a flow bench(you got one of those?) and replace all the guides, valve springs, valves, bearings, re-balance and blueprint your're still not done. What else, then you have to go buy the turbo, boost controller, intercooler, ecu, injectors, fuel pump, etc...
I'm just trying to say, **** bolt-ons. You're going to nickel and dime yourself to death for minimal horsepower and maximum headache. Swap that motor FIRST and then see where you can go from there.
Oh yea, speaking of nickel and dimed to death, anyone wanna buy a SLIGHLTY USED
