It would seem far less logical to buy an SR20DET and then pay even more to modify it to the hilt, when the KA24DE can make significantly more power for the same price. For what it would take to buy and modify the SR, you could build the KA through the roof. The benefit of doing this is better low end torque, and greater airflow potential throughout the RPM band without having to bore the block out and doing a bunch of machine work. You could just as easily port/polish, and gasket match the intake and head for even greater flow. I would bet that you could save so much else where in the upgades that you could pay to have proffessional head work done, and upgrade to larger valves and better valvetrain components for the same or even less than the cost of the SR swap with bolt on upgrades. There are tons of cams, rods, pistons, valvetrain components, drivetrain components, ignition, turbochargers, manifolds, BOV's, wastegates, intercoolers, and whatnot that are made specifically for the 240SX/KA motor that it is rediculous. Even better, you can buy a KA for about $700, complete, and it will be newer, cleaner, and lower miles than the SR is likely to be (Not in all cases, but hunting will certainly pay off). Sorry, it just seemed to me that there was a lot of KA hating going on, and as compared to the SR, they are actually really great motors for modifying.
