  1. TJ Wrangler Technical Forum
    I know I may get a lot of heat from this one, None the less, I have swapped a Ford 302 Drivetrain into my 97 Wrangler. The Ecu is basically a gauge mule at this point. However, the tach and speedo do not work. I found that in order for the ECU to send a tach signal it has to see the crank and...
  2. KL Cherokee 2014 & up
    alright so let me start by saying that the odds of me doing this are insanely low and i only thought of this because i'm in love with smaller engines with turbo kits (and also big NA V8s but that's not important) and i want to drive a faster car as most guys in their early 20s do. so my idea...
  3. TJ Wrangler Technical Forum
    I'm swaping a VW TDI engine into my TJ and I'm wondering what others have done in general about possible check engine lights. I'd like to avoid simply taking the bulb out if it makes sense. I'm going to be sending the Jeep ECU a converted crank trigger signal for the tach. At the very least...

    I currently have a 4.0 engine that just crapped out on me. Rod knock and is looking like an engine rebuild. I don't want to sell the car because I finally finished the interior before competition safety requirements. I'm trying to do rallies, unconventional already I know. Due to class rules...

    The first car I ever has was a '86 CJ7 - that was in 1988. It was stolen from me a few months after. I always thought I'd get another one day.

I had originally planned to rebuild the engine, but today I found a 1995 Jeep Cherokee Sport with a 4.0 and 133k miles for $500, so I bought it to serve as a donor.

  20. Engines & Drivetrain
    I have an 89 YJ with the 2.5/5 speed. For a while now I've been thinking about doing a 4.0 conversion. It just seems that 4.0 YJs are almost nonexistent around here. There's a place a little ways from me that specializes in Jeep parts. I talked to them a week or two ago and he said the only 4.0...
