It's out there already. I have a 20r/22r hybrid motor from D.O.A. racing, and was interested in getting a EFI intake on. Turns out Tim Jenkins of D.O.A. can make you the adapter to bolt on; sandwiched between the EFI intake and the 20r head. Though Tim said it was easy to do, you have to drill out a hole in your 20r intake :cry: :sob: for the coolant passages, and also drill and tap some new bolt holes for the adapter and intake since the 20r doesn't match up
I decided I'll wait until I have to rebuild the head, and then swap in a late 22r EFI head. Or just sit and see who is gonna figure out a throttle body injection for the early toy motors, I have a Holley 4bbl now, and it wouldn't be to hard to move over too set that :up:
Call Tim for more info (you can get his number off his website doa racing). Good Luck!!!!
