Probesport's 1988 Grand Wagoneer build
So far I have been posting threads as projects, but there are so many little things I do on a regular basis that I wanted to consolidate it into a build thread. This is a daily driven Jeep, moreso in bad weather or parts hauling situations.

When I got it it looked like this

which now looks like

and the engine was

and as of this thread it's now like this

Here are some of the builds/projects so far.

Aluminum (eBay) 3 row radiator and contour fans

Painted the top of the tank black

and added the contour fans.

The fans are triggered off of the Megasquirt and powered by a small relay and fuse box

For this and other new loads, I also added a 165a Alternator - forgive the chrome, its just how it was....

and I recently replaced the overflow hose with a tube

I bought a carpet kit from BJ's (which seems to be my most go-to supplier) with mass backing and new floor mats. I also got new door sills at the same time.

I strippped the inside, repaired some floor issues, primed, painted, sound deadened, made new backer panels, and finally installed carpet. While I was there I installed some audio via new tweeters, subs, capacitor, amps & amp rack.

I have not put the strips in the cargo area yet, I plan on redesigning them a bit.

New exhaust from BJ's, saved a ton of time versus making my own. The kit is wonderful, the supplied clamps are not. Washers make teh clamps usable, but I ended up replacing them with auto parts store ones

$5 Amazon cup holder

cut out the CD storage section.

slide under center armrest

Under the carpet there is a 'christmas tree' that holds it in place after drilling a small hole in the tunnel

Probesport 02-01-2019 01:57 PM

Random wiring cleanup, I've avoided using plastic tape and zip ties to keep noises, rattling, vibration down.

also added a battery charge/trickle port

and fixed the underhood light

Power wire for amps go through the bracket/hole under the heater core.

Amps are all mounted in a rack to hold them in the rear fender well

LED headlights

Aux and USB ports, RS232 for Megasquirt in the ashtray.

Probesport 02-01-2019 02:08 PM

I just did new pads, discs, and drums all around weeks prior) which then got me on a path wanting all new lines and hoses and found me wanting calipers as well.....

Track arm mount repair...

and everything got new bushings

and diff fluid changes with new HD Dana covers

You do tidy work. Thanks for sharing.

I like the EDIS coil pack setup. I used one after I went to crank trigger on my MS car. They are really neat.

Probesport 02-04-2019 11:39 AM

Thanks, I do like to keep it neat enough to work around comfortable, especially being a daily driver it gets its share of abuse.

Yeah DIS is great, its always step 2 of any Megasquirt install we do so much better control. With the Jeep being EFI and DIS it's become so much more consistent and I am finally at a point that I just get in and drive anywhere.

This past weekend I shortened the Crown Vic wire set I was using and put 45deg boots on there. The crown vic ones worked, but were longer than necessary and the boots were just huge.

Here is the original wires.

Probesport 02-12-2019 10:25 AM

I was replacing a flickering bulb in my cluster so I decided to clean it up, resolder some loose joints and color the gauge needles red.

The contrast is so much nicer, I never liked how the white needles just seemed to wash.

I also addressed a turn signal cancel issue (broken spring) and some misc cleanup while I had things apart.

Total drool. Amazing stuff.

Do your USB ports go to your amp or do they just do recharge?

Probesport 02-13-2019 08:02 AM

Thanks for the compliments.

The USB ports in the cigarette lighter area are just power (QC/FC) and the one in the glovebox goes to the head unit.

Just ordered a twin stick setup from rocklaurence, so that will be next up.

I also have new oe style door seals ordered from BJ's but they are on backorder, but that should be a welcome improvement over the universals I have on there now once they ship/arrive I'll post them as well.


Probesport 02-25-2019 02:04 PM

I received my rocklaurence twin-stick over the weekend, based on the install instructions I received prior I felt I was going to be re-doing quite a bit of it but luckily those appeared to be prototype or older pics because this unit is actually quite well made for a small (individual?) operation.

Really, even from a perfectionist perspective the only thing I would change is the linkage connection - I think rod ends would be a better solution but that is not to denigrate this kit at all as I rarely leave anything stock, even aftermarket products.

I plan on doing the install this week as-is most likely, and will document as I go.

I also polished up the wheels nad put a coat of wheel guard on them, the salt/snow and bare aluminum is a terrible combination - I may have these powdered clear or finally refinish my original wheels.

and I got this too

Subscribed. Nice, very clean build.

Do you have any sound clips of that BJ exhaust?

Probesport 03-11-2019 01:17 PM

Thanks for the compliment, no I do not have any audio/video yet. BJ's has a few clips on their site but I will try to grab one next time I'm out taking pics.

In other updates: I haven't put in the twin-stick, some projects with other cars have been taking up some of my time.

The door seals from BJ's have shipped and I should have them here on Friday! Took about a month to get them due to them being out of stock but out of the blue the other day I got a notice that they have arrived and are on their way. I have usually received most of my BJ's stuff quickly (within a week) so this is probably an outlier, hope they were worth the wait...


pickledtoast 03-11-2019 01:50 PM

I'll end up getting the BJs exhaust as it's a deal, but I figured it couldn't hurt to ask for a video. The old youtube videos on BJ's site are not very good.

Probesport 03-11-2019 02:02 PM

No worries, and yeah they will all sound different. I have shorty headers, EFI. and the BJ's 3". I will say I do not like loud exhausts nor the 'muscle car' sound so I was a bit concerned but it sounds great without being obnoxious at any speed. I had a Borla muffler on earlier before I went to a stock style muffler because it sounded like hell and crazy loud.

I have done a bunch of custom exhausts myself, and while its a simple setup I think the price is very reasonable. Once you price out the mandrel bent SS piping and the magnaflow muffler it's not much of a markup so that's why I ended up pulling the trigger.

My only complaint was that the clamps were not great because the nuts pull into the lower clamp. Either address with some thick washers or just toss them for better clamps. From a stock replacement setup to this was an absolute necessity, especially after EFI you can tell this engine needs to breathe. I consider the 3" exhaust a must-have now on a JGW.
