I just bought a 2.3 EFI motor for my VW Fiberglass buggy. It weighs about 1100lbs, What can I expect in horse power ? Also what computer do I need, the motor came out of a automatic 1992 EFI Mustang non turbo. Dose it have to be an automatic or can I just buy the one for the standard . The cost is different at the parts storeby about $75-85. And I just ordered the wiring diagram from Helm Inc for about $18 . I will be only running an altanator and belt. I will have to get a header made for it to come out the back as it sit in the car as would a Air Cooled VW motor also using a K&N air filter. . If any one can help me I would be very thankfull.
