Asked in Jeep Wrangler
You want to replace the 2.5 engine in your 1994 jeep wrangler with a 4.0 v6 is this possible And if so would you need a new transmission to replace the manual you have already?
I'm considering swapping the engine in my 98 Jeep Wrangler (a 2.5l 4) with the 4.0l 6. I haven't done so yet, but I came across a website of someone else that has: http://www.jeepaholics.com/tech/25to40/25to40.htm That may help you out, or at least give you a little more to go on. Sorry, I realized I didn't make it clear: My jeep is a 98, but the jeep on the above website is a 94.
