Title: 1986 Wagon Project
Post by: Nightpath on August 01, 2014, 05:00:52 PM
I've been debating for a while whether to keep the old girl stock (or as stock as possible), do a SFA conversion...or tonnes of other things. I really can't decide what to do.

Here is what I'm definitely doing though...so I need more suggestions!

- XJ motor/drivetrain conversion
- D35 rear axle w/3.55
- replacing windshield, resealing back windows, new window seals (have all the stuff)
- almost have the interior done (ceiling left, some trim to install)

Here's what I'm looking at :

- need replacement seats - might rip these from an old Eagle, but open to alternatives
- replace the stock steering wheel. I can only imagine stopping fast and becoming toothless
- stereo + speakers -rear XJ speaker bar?
- Jeep rims/bit larger tires

Possibly :

- repaint


If you had a bit of cash, what else would you do to your wagon? Nothing overboard or insane, but upgrades and other stuffs that would make the car that much better.

I havent done it yet because I am getting the major body/interior issues fixed but the following in that order (pending on parts availability) is what I see as worth while modifications for a nice riding eagle.

Front SAS- I would like to replicate what the factory 4 link JGC's have as best I can and that should open up all JGC aftermarket parts.
Rear axle swap- also replicate the 4 link the best I can for aftermarket parts reasons.
5.0HO SBF engine- light, small, aftermarket parts, reliability and power. Engine/Trans harness pretty much standalone.
Explorer trans/tcase-matches SBF pattern obviously, reliable and upgrades readily available.

People on forums swap EFI SBF's into jeeps all the time...should make most of it pretty straight forward.

For me the XJ drivetrain is a solid upgrade, and there are chips and tuners out there for it to eek out bits of performance/MPG and so on.

Sounds liek a sweet plan though :D

Skid plate, if it doesn't already have one.

Save yourself a ton of digging. Look into a long arm set up from an XJ to put in at least the front of your Eagle to do a solid diff swap. 3.55 with stock Eagle tires will SUCK the fuel down.

I'm swapping over to P235 75 r15 when I get the chance, and if things go right I hope to dig up some 3.21 gears. The responses to 3.07 were that they would be too low for the AW4 to work properly.

Might be an idea to look at OBD1 tuners and chips if I want better MPG. I have co-worker who sunk some money into one for his Liberty, went from 15-16MPG to 24MPG (less torque at the low end, few more differences)

I ran my first Eagle wagon with 2.37 gears, a high stall lockup converter and 235/75/15s. It was a bit sluggish off the line, but cruised at 70-80 mph no prob with the 282 motor I had in it.
Title: Re: 1986 Wagon Project
Post by: Nightpath on August 04, 2014, 08:33:59 AM
What motor is the 282?

Think 3.07 would work with the stock Jeep XJ drivetrain?
Title: Re: 1986 Wagon Project
Post by: carnuck on August 04, 2014, 02:18:43 PM
http://en.wikipedia.org/wiki/AMC_straight-6_engine#282

3.07 is what Jeep ran with the 5 speed stock with bigger tires than the Eagle came with.  I ran 33" tires on my '87 Comanche back when it was 5 speed and still had 3.07 gears. Off the line with a load wasn't speedy, but about the same as my Eagle with 2.72 and 235s. The AW4 has a better torque ratio in their converter for taking off but you still want to match the original ratio to tire size within a percentage. It will also depend on whether you go HO or Renix EFI. The HO really needs lower gears for takeoff but it's within the percentage to run the same as Renix. They just changed the O/D ratio to keep it in the power band.
   O/D for Renix is .70 and HO is .75 which doesn't seem like much but at 60 mph it's 1564 rpm vs 1676

Mine is from a 94 xj. HO and obd1

Title: Re: 1986 Wagon Project
Post by: Nightpath on August 05, 2014, 01:43:19 PM
Automatic....has the aw4 transmission common to the 94 xj.
Title: Re: 1986 Wagon Project
Post by: carnuck on August 05, 2014, 01:55:34 PM
Then 3.55 ratio or 3.07 will work.
Title: Re: 1986 Wagon Project
Post by: Nightpath on August 05, 2014, 03:50:50 PM
Hmmm....3.07 is tempting. I just don't want to have it go too low rpms wise since I plan on putting on some 28-29" tires. Some of the Jeep guys and a few here said that with the 3.07 fit that it didn't like overdrive too much.

I'll get the swap done and 3.55 axles then work from there maybe.
Title: Re: 1986 Wagon Project
Post by: eaglefreek on August 05, 2014, 04:35:19 PM
In my opinion the 3.55's are almost perfect with that size of tire. 3.73's if you plan on towing anything with some weight to it.
Title: Re: 1986 Wagon Project
Post by: attemptnumber2 on August 06, 2014, 09:57:57 AM
IMO, your RPM range should match or be slightly above the factory RPM Range. For instance, you want drive to match drive not drive to match overdrive. this is so when pulling sumething you put it in D and pull it and it is just like it was designed. when DD'ing you put it in OD and away you go. OD was not meant to be used to tow until around 2000'ish. with electronic control, solenoids and what have you being fine tuned manufacturers have it down to science.
Title: Re: 1986 Wagon Project
Post by: Nightpath on August 06, 2014, 10:37:54 AM
I don't tow, just my daily driver.

I've been asking the Jeep guys who have the same ride what they think. It's the same with them, 3.07 would work as long as I don't go too large of a tire. I think it'd work with the AW4, but with 27"ish (P205 60 R15 maybe) tires...I'd like to rock out 29"ish (P235 75 R15) since they are uber common around here and look really nice on the Eagle with Jeep rims.

Don't limit yourself though. Keep your eyes open for ZJ (Grand Cherokee pre '98) 16" rims and you may be able to go 235/85/16 which is also common on newer trucks.

235/85/16 is around 31.7".  Way too big for most eagles.
Title: Re: 1986 Wagon Project
Post by: Nightpath on August 06, 2014, 01:58:07 PM
I think I'll stick to the 15" rims...maybe 16" but the tires will not be really large.

The raging debate between 3.07 gears and 3.55 is still happening. Heck...in this post alone I have 2 people saying either is good!
Title: Re: 1986 Wagon Project
Post by: attemptnumber2 on August 06, 2014, 11:41:20 PM
My opinion but 3.55 if you do any in town driving. I Had 3.08 in a 3 speed auto truck with 35's and quickly toasted the transmission. OD and less than 3.50 gear ratio will be really hard on powertrain.
Title: Re: 1986 Wagon Project
Post by: Nightpath on August 07, 2014, 05:33:44 AM
Did you drive with smaller tires? 35", 3.05 and OD no wonder...you must have been ridiculously low in regards to RPMS.

When I do the checks with 3.07 vs 3.55 and a set of 29" tires it seems that the rpms are around 1650-1700 in OD. 3.55 is around 2000-2100.ill be leaving the stock axles in after the swap (for testing purposes). Depending on the rpms range I get with 2.73 and p205 70 r15 it might help me make up my mind.
Title: Re: 1986 Wagon Project
Post by: attemptnumber2 on August 07, 2014, 11:50:48 AM
at what speed? i had 30-31" tires on it initially and it was at 24-2600 highway speeds and not having a lock up converter.

overdrive is ~.70.
the way i look at it is your engine is putting ~220 hp out to the flywheel at 2200 rpms. by the time it makes it through to a .7 ratio it puts a lot more stress on transmission.

turn the driveshafts to the ring and pinion. a 3.07:1 ratio vs a 3.55:1 ratio  puts you at a 2.149:1 vs 2.485:1. theoretically you now have 330.946 hp vs 382.69 hp.,

turn the axles to the tires. 29" tires sets the torque finally at 136.941 hp vs 158.352. 22 hp difference is pretty noticeable by the time you break it down through the system.

I realize these cars dont have 220 hp but just used it as a reference number. I could be wrong but i am pretty sure hp is more applied to actually driving down the road than torque.

also i did not figure in lost power due to resistance. at 1600 rpms you are not in a power producing area of the engine. at 2000 i feel like you would be.
Title: Re: 1986 Wagon Project
Post by: Nightpath on August 08, 2014, 07:14:08 AM
I was rooting around at different ideas for the past few days. I think what I will do is stick with 3.55 and run a bit larger tires.

Down the road I'll probably snag a throttle body spacer and upgrade the distributor to run hotter. IA what was suggested to me on another site... For a bit of extra it ought to give me 20-23 mpg easily, and the car isn't a brick like the Cherokee.

I am mighty tempted to keep my stock transfer case though. Having full time 4x4 is so so tempting.

It's been a long time since I've posted about my Eagle.

Since last March, I've had a lot of ups and downs. The original fuel tank was blocked at the vents so it didn't pressurize properly, then the fuel pump burnt out...it stopped me on the side of the road about 20 times until if finally croaked in front of the Wing Commander's house on the main drag at 3:00 on a warm sunny long weekend Friday afternoon.

Yup, I was THAT lucky.

At this point in time I parked it in my driveway and gave it the middle finger. I went to the bank, got a loan and purchased a Jeep TJ which I enjoyed. I did a bit of work on it and drove it, enjoyed it.

I decided to wash the Eagle with a pressure washer from a friend before I tucked it away in my garage (this was in July or so). Huge chunks of paint sloughed off onto the ground...I'm talking dinner plate large, 3 huge chunks. I almost cried. At this point I started to look at buying a deck sprayer and giving it the olive drab + satin black treatment and make it a badass looking rig.

(http://i85.photobucket.com/albums/k78/nightpath/1986%20AMC%20Eagle/FB_IMG_1441134068176_zpsab23tp9s.jpg) (http://s85.photobucket.com/user/nightpath/media/1986%20AMC%20Eagle/FB_IMG_1441134068176_zpsab23tp9s.jpg.html)


I tucked the Eagle in my garage for several months until I decided to get it running first, so I wasted a bit of money then got smart and I bought a Cherokee XJ tank and sender. I pulled my old tank, cut out the fill hole, had it welded to the XJ tank and slung it up underneath. This was in February/March when I got it running again. After it smoothed out I was pretty ecstatic to have it running.

I pulled all the interior out (well..still need to pull 2 more pieces but oh well), outside trim, and whatever else. I decided to get it painted properly so I sold my Jeep TJ and started to make things happen. I called around until I settled onto a buddy of my brother in law. It's now sitting at his house getting a nice new paint job. I have a tub full of suspension components, a box full of new electronics (speakers, wiring, amp, sub, etc). I cut out the cancer in the rear and had it fixed.

So now I sit, waiting to get it back from paint so I can reinstall all the trim, etc and get it inspected.

Finishing up the exterior. I still have a lot to do, but most of the big stuff is done. The interior needs attention (basically install and some wiring), and the front suspension needs a few odds and ends replaced (which I have).
