First I would like to say thank you for putting a KA into your 510, belive me my dad has one already finished and I Love driving it It has awsome power and for a little extra money and a turbo you can smoke the SR fans and still be under there budget doing so. FOR THE TIPS, just let me know. I am currently doing my own 510 KA swap so shoot me a question on wiring, motor mounting, tranny mounting, vacume, emissions removal etc. I have one good tip though. You can use your old alternator on the KA motor! If interested I can tell you or show you a pic!
JoeyP.S. I can build you a custom front crossmember cheaper then you can find one online, no ! I use your crossmember and modify it accordingly. let me know if your interested, I can send you a pic as well!
