Cole; Some of the 2.3 turbo's were run without inner coolers. They were limited to 8 PSI boost I think. I already have a complete driveline. I'm looking put it in a Model A or B. I see that the 28-29's are a little narrower them 30-31's. But the 28-29's seem to be easier to find and cheaper. I think I need about 26 inches width because of the turbo.
latech; I put one in a 84 Mustang. These 2.3 turbo's are fun to drive. The little booger pulls pretty hard. It's a 190 Hp stock with the small inner cooler.
