I recently bought an 83 prelude parts car with a manual transmission in it. The motor and transmission have about 130k miles on it. I pulled the motor last weekend and realized there are a few differences between the 83 and 84. One of the differences was the engine code, the '84 being a et2 and the 83 an es1, 2, or 3. Looking through engine parts, the only differences I could see were either in the intake manifold gasket or the exhaust manifold gasket. I'm wondering if the transmission will bolt up to the et2 block. I think it will, but I would like to confirm it here.
The 84 prelude has 50k miles on it. I'm torn on if I should see this project to the end, or just leave it untouched.
My possible plans are rebuilding the es1 motor, and installing a weber carb, or only swap the transmission in there.
