Has anyone successfully done this yet? I'm sure this has been discussed before but I am somewhat new here. Will the motor handle the stroke at high rpm's? longevity? Also, which internals to use?(KA crank, sr rods and pistons, etc.)

one of my friend told me he had a 240 and i ask him did he had sr20 heads on the ka and he said something like that so i dont know.. i was pretty lost but his car was pretty fast.. he had custom intake with a supra adapter and just free mods he did himself.. he showed me vid of him beat some turbo cars.. pretty crazy

Yeah, what all do u have to do, now that i am putting in a jdm engine in my car, I have a spare sr20 to rebuild. Might as well go all out!

It can be done. JWT is working on their kit as we speak. I believe you have to redrill the flywheel holes, bore out the main caps and whatnot. But watch the rod length!
