I've done a few odd re-engines -- Pinto motor in a 55 Nash Rambler, and various other motors (mostly in Ramblers!). The J-10 I'm building now might be getting a 2.3: turbo four from a Merkur XR4ti. All the Jeep/Rambler guys are skeptical about the turbo four in a full size Jeep, but it puts out about the same torque (albeit at a higher rpm) as the original 258 six and about 50 MORE HP. I know I really need torque more than HP, but the thing has 4.10 gears and will have a Ranger five speed 4x4 trans. Should be at least as strong as the original six and get better gas mileage. Only drawback is the 175 hp four needs premium fuel, but 16/22 mpg on regular or 18/24 mpg (city/hwy) on premium is about the same cost. The 16/22 is about what I was getting with the 258 and a four speed with 2.73 rear gears (4th is 1:1, but with 2.73 gears was about like OD with a five speed and lower gears), 18/24 is what I expect from the turbo four. Would be a lot more interesting vehicle with the turbo four too!
