I should be wrapping up this swap in the next couple of weeks. Ran into a neighbor on another forum and I decided to spread this to the other Jeep forums on the net.

Dude this is beyond awesome. I always thought this or a Nissan RB26-DETT I6 would be awesome swap for a street XJ.

1JZ, 2JZ, RB25, RB26, RB30, etc.... would be AWESOME in an XJ. All of those motors sound so great!

I've been following your build over on NAXJA, killer work bro!

Yet everyone *****es at me when I say a turbo done right would be perfect for an XJ.

only on the right engine...

I did put an RB-26 dett into a 78 Nissan 280z. I love the way that engine looks.

Updates on parent forums!

I just messed all over myself.

Sounds like it idles a bit rough.

It's a junk yard motor that has been sitting for who knows how long. Good observation though.

I guess.

It wants to stall if you open the throttle with any sort of quickness.

Boost leak would be my guess.

Are you running blow through? I'm not super familiar with that motor, but I know enough to get myself in trouble.

Boost leak testers are really easy and cheap to make.

Get a 'test cap' from the hardware store. Should be a rubber cap with a hose clamp around it. Get the size of your turbo inlet. Drill a hole in the top the size of a tire valve stem plug the hole with the stem. Clamp this new assembly to the inlet of the turbo and use your compressor to pressurize the system. If you lose more than 1 psi per second you know there is a leak.

Spray soapy water over the IC pipes and look for bubbles.
