Then I pulled the tiny little 2.5 out of its hiding place...AX5, NP231, and all




Exhaust is overrated. Will probably keep the cat and scrap the rest.


No need for the radiator anymore

Transfer Case...Picking up a 23 spline NP231 with a SYE

Driveshafts...

Transfer case will mount back into the stock location allowing me to keep the stock front driveshaft. To keep this build on a budget, I'll be pulling a front driveshaft out of an XJ and shortening it for the rear to use with the SYE.

Motor work...

Previous owner said he was driving and the oil pressure dropped so he shut her down and towed it the last couple miles home. From what I've read, it could be as simple as a clogged pickup or something easy. I'm going to pull the pan and probably replace the rod and main bearings.

Cracked heads seem to be a problem with the 318/360, so I plan on pulling the heads and getting them checked. I may have a simple port/polish job done on them while they are out.

Cam shaft. Its highly likely that I will replace the cam, but we will see what the funds allow.

In order to keep the tcase in the stock location and retain my driveshafts, I'll be using Summit's block hugger headers so I can scoot the block closer to the firewall. I plan on building my own motor mounts. The AA mounts are nice, but I'm on a budget and 150 seems a little steep.

Wiring...

Wiring could be a bit of a tedious task, but it shouldn't be bad. I'm in touch with a couple people that have done the swap, and it sounds like the wiring appears more discouraging than it should be. I have some experience wiring things up, so I don't foresee it being a problem at all.

Here's where I'm at right now.

200 for a trans
200 for the motor
200 for the tcase

Sold my motor/trans/tcase for 500, so I'm only down 100 at the moment. And as far as time goes, it took me half a day to yank the stock drivetrain by myself. Now I just need to start ordering some parts and tear the 318 down to make sure everything looks okay.

I did the same swap in my 98 with the 5.9. You are going to love the power! Also I found the swap radiator on ebay for 230.00 shipped, it's direct bolt in and made in the usa. The grand v8 fan works great with the factory 6cyl shroud as well. The 03 od switch is great too. It fits right in the dash knockout and looks factory.

Thanks for the heads up! The radiator that you used, does it have a tranny cooler as well?

I plan on ditching the mechanical fan and just running an electric. What do you think?

I thought when doing an engine swap that you had to have the same year engine or newer than the vehicle's year?
