You can use the truck fuel rails, but they need to have adapters made and new o-rings since they are longer than the car injectors. You can use car injectors and rails if you change out the wiring harness pigtails. The rest of the difficulties involve cutting the alternator braket, relocating the idler pulley, relocating the water pump outlet neck to clear the TB, fabricating an CAI that is lower for the lower car intake, which may or may not clear a mechanical fan shroud.

Search for threads by Kano, he did the swap recently and it came out very nice.

why do you say you need a 90mm tb? that may hurt your performance actually if your combo doesnt need it

Well that is some good info. One less thing to deal with.

i was just going to get the 90mm because i thought it would be a good idea, i'd be running a 226 .575 114 cam and eventually a 150 wet shot sometime. ill have to search kano's thing. i'd like to do the intake right. keeping the truck fuel rails would be nice but with all the braket and neck and other modifications seems like a pretty difficult job. i wonder how much someone would charge to do all that stuff...
