you can adapt the mfi inlet by opening up the injector seats, then use a fez turbo fuel rail and reg, youll need to weld on some sort of posts to hold the rail though.

the efi inlet can be used but if youre going to be keeping your mfi head youll need a conversion plate as the mfi head doesnt have the cut outs for the injectors.

injectors wise, all depends on what sort of power you want.
