damn! that sucks, sorry to hear that. the thing i think you should do is get another ka24e or ka24de. it will be allot cheaper than swapping it to a sr or any other motor swap, it will be allot less hassle because you won't have to do the 27 extra things to get an sr working perfectly with your car. and don't forget the most important, the price, you can get a ka for $200. in working order. you can get a rebuilt block for like $275. and drop it in to your car. you can always rebuild your own motor too, but that will cost from $200. to $1000. its your call. good luck!
