Just turbo the KA on the stock block...it has to be cheaper than an SR swap, plus you still have the extra .4 liters of displacement to play with (torque

). If anything throw a little thicker headgasket (like stated above) to lower the compression a bit, tune it and take care of it and it'll last forever. Besides if shit breaks on the KA you can go to any mechanic to get it fixed easily, SR isnt so easy to do that, I know, I have one.
