the sr20det is a 2.0L with a turbo and an aluminum block. the ka24de is a 2.4L non-turbo(NA) with an iron block. while the sr20 does have 50 more hp stock the ka is still a great engine. the advantages of the sr20 are that it is turbo'd from the factory and has huge aftermarket support since the silvia (japanese version of the 240 if you didn't know) is about the most popular car for young auto enthusiasts over there. the ka24 on the other hand, has 400cc's more displacement, giving it better torque an iron block, and a fairly low (read: turbo-friendly) compression ratio. these all add up to an engine that can take 300+ hp with out building the internals. once you do build the internals, the ka still has the advantage of being an iron block, allowing it to hold more power than the sr20. the sr20 block is not really reliable past 500hp. getting more than that would require you to put iron cylinder liners in. then again, do you really need that much power? the fact that the sr20 is designed for RHD also means doing that swap will require modification of the wiring harness. boosting the ka would still be my choice though, since it will have more low-end torque. the only disadvantage to the ka is that there is no way to adjust cam timing due to its two stage timming chain. also, it will be a little hardr to find parts, but just about anything you could need is made for them, there just aren't 50 different companies to make each part.
