Can you convert a 97 Jeep Wrangler 2.5L Manual Transmission to a 4.0L Manual transmission without changing a bunch of stuff?
No. You have to change everthing. The wiring harness, radiator,
computer, and the engine mounts will all have to be changed. Not to
mention possibly the gas tank and fuel pump, bc some years they ran
at different fuel pressures. Sell the o'le under powered
four-banger and get the six. It would be alot easier. Good
