Ok, I think I got this thing working now....


Here are some pics of my intake/intercooler piping

For the piping I just bought a box of random exhuast pipe "test" bends off of ebay and pieced it together.

So I spent a TON of time redoing my firewall to fit an XJ HVAC system, I will save that for another thread, but I also had to make a new battery tray, and fixed the firewall by the master cylinder to relocated the bulkhead connector.

I also made a dual power distribution mount, and mounted a dual pump washer bottle from an XJ.

XJs are allllll over junkyards, so I tend to just use parts from them.

Last night I managed to get my vacuum pump wired again through my auto shudow relay, and ran all my vacuum lines.

I am quite proud that I got the 2 position switch o the left to control my parking lights/headlights, and the dimmer switch to work, to dim or brighten all the dash lights.

Pulled an 8.8 from an explorer with 3.55 gears. I got the axle, calipers and rotors all for $105, not too shabby.

It is not my first choice in rear, but for sure the cheapest and easiest to get rid of the D35, it will do for now.

Thanks guys, it has taken a backseat to a boat I am re-building lately. I hope to get back on it in April.

That's actually a whole lot less than I thought.

The more important question is;
Have you been tracking hours?
If so how many hours are involved in the project?

Where is the fun in tracking hours!?! Haha, this is just my project when I have time.

The first go around just to get it running I can say I spent 5 days a week about 8 hrs a day, for 6 weeks, and probably that over again since then, soooo, around 500 hrs?

I bet I have about another 1000 hrs on this thing, I still have a ton of plans for it.

A shop near me quoted me $10k to do mine. That supposedly includes everything.

That is actually a really good price. There is a shop called Jeff Daniels Jeeps in PA, they do 4BT swaps a lot, and quoted me at around $20K , including engine, trans and everything, which I thought was absurd.
