86 XJ w/MPI budget (re)build

I hope you all are interested, I've been trying to get some response and help elsewhere but this seems like a good place to post up my original plan and how things have progressed.

Background: Got my 86 2.5TBI 5spd Cherokee when I was sixteen, after totaling my 97 Dak. The jeep ran great and had cold blowing A/C, but things went downhill quickly... I'm basically a broke pre-college student, minimum wage trying to gather parts, so bear with me please!

First mod: Junkyard lift! (most of these are crappy cell phone pics, sorry... I'll replace them with real ones soon!)





Front lift: Approx 4" (had a nice little gangster lean, get to that later)



Rear lift: Approx 3.5"



I apologize for the random sizing and such, I was barely seventeen and just learning how to get my intarwebz pics working!

My process was as follows;

ZJ V8 springs front w/1.25" spacers replacing my old isolators. That's about 3.5" with the coils alone.

Rear XJ pack (main and second leaves) bastardized into mine for 3.5"

I couldn't find a cheap shock solution at the time, and my stock shocks were okay, but last year I found JK shocks for $50 bucks, so I put them on and made BPE's for the rear with my stock rear sway bar brackets.

I wanted tires but I've never had a consistent job to pay for them and my parents haven't supported me much the whole way...

Until late summer '08 I beat the living crap out of the thing to try and finish off the old TBI system, and in the mean time started gathering parts and researching for an MPI conversion. The system never got worse, but the engine decided to blow its' #2 cylinder rings... on to the next stage!

Tear down! (still more cell pics)





This thing was DIRTY!

Old trash:




New stuff:







... I'm getting there! Got it started today, but only after rigging up the starter, something is wrong with that circuit and I need to do some rewiring... But other than that the idle immediately shoots WAY up and stays there, I think my IAC is seized, it's one of the few electrical things not brand new...

Jerry-rigged, semi-working order (finally real camera pics):




Custom cable-to-electronic pass-through adapter from dakota digital (made for GM transmissions, but should work), it's half-wired up too, haha:



... and that's it for progress, I'll get pics up of the free 15x8 eagle alloy rims I got, hopefully with some new rubber mounted to it... planning 31's, finally got some money from a consistent but low paying job. I also obtained a rusty's adjustable TB, but no bracket, so I'll have to purchase that to solve a small (.5") lean I have from the axle being offset. I'm gonna install some chevy 3/4ton shackles in the rear to even it out, then probably go DB's to improve ride/flex, but all of this is going to be fairly slow to happen.

I need you guys to help me figure out the idle problem though... Is the likely culprit the IAC? I don't want to start throwing money/parts at anything yet! I want it running/drivable this week... it's been down for 5 months now!

Thanks for reading this far! Please post with feedback/criticism/help, I still have plenty of other small plans for it, so if you have questions please ask!

Oh yeah, and I'm only almost 19 now, trying to get this thing working and reliable for college this fall (I took a year hiatus from school).

Drove for the first time since tear down in early december! 4/20/2009!

Nearly NOTHING is hooked up, no evap system, no CCV, no blower motor, no heater, no washers, no fuel gauge, no vac disco, no vaccuum canister, and a whole bunch of things need to be secured properly...

But I figured out that the high idle was from a massive vaccuum leak at the manifold gasket, just needed to torque down the nuts/spacers.

The starter problem was a lack of ground to the starter relay, we just jumpered the wire to a ground with alligator clips and it started with its' own relay this time!

As for how it feels to drive it now; definately more power than before, but I know I still have alot to do before it feels as nice as I want, there are various holes and leaks past the muffler, I'll have those welded up for now.

I'll update with pics of new tires and everything when it all happens.

I think I'll just blog this or something, no one is responding anyways.

Looks like you are doing a great job with the build. Keep up the good work. Good looking XJ by the way. It'll look great with some new tires.

Haha, wish it was good looking! I'm going to remove the pin stripe, paint the hood black, then bedline the entire front fenders and the lower half (below door handles) from the fenders back, as well as trim the both front and rear fenders. I foresee four wrangler flares in the future if arizona decides to step up on the "flare" rule.

Twenty three years of heat practically fused the lower trim to the paint, so when I removed it alot came with, on top of that I picked a fight with a hidden fence post and gouged my front fender real good, so I figure I might as well bedline the whole lower half.

Believe me I am incredibly excited that I pulled this off! I spliced three completely different year/vehicle (86 XJ, 94 YJ, 97 XJ) wiring looms together and managed to get it running, all with NO prior vehicular control system knowledge! Props to my dad and my electronics/engineering/physics teacher who both learned me ALOT about general electronics over the course of six years!

Hey man, what's up? sorry I'm slackin and just saw your thread, actually caught the link in your sig somewhere else. Guess I'll have to start looking in the registry once in a while. So looks like you finally did it and got all those jeep genes hybrid-ed into one, props on that!

I'm cheesin on the like zero rust you're sportin, must be nice to see a jeep last like that. Around here it's a constant battle to keep rust at bay, and it gets everwhere!
So are you thinking maybe some white bedliner on there? Seems like black might generate a lot of heat.

Nah, Black bedliner still, plus I'm moving to Prescott in a couple weeks so the climate will be MUCH more tolerable. I'm anticipating salted roads during the winter up there, but I ran a complete coat of underbody coating so not only is the original stuff in tact, but it's reinforced w/o any rust... I hope it holds!

As an update, hooked up vac lines for the 4wd, but it's making horrible sounds and the front DS seems broken.... I'll chase that down soon.

Got some Goodyear Wrangler 235/75r-15's mounted to my 15x8 (3.75" BS) cragar 51 (I think) mags. Not the preferred tires, but they still look awesome and make the jeep sit very nice. I still want to install some shackles, but that will be my next day off (sunday).

Wipers, blower motor, and all lights are hooked up... now all I need is to wire in the back-up light (not a big deal), hook up my fuel guage, and install my stereo in order to finish ALL wiring!

I need to fab a way to mount the front fenders again, the aluminum mounting strips destroyed themselves upon removal. With 31's I thought I would have to trim, but the 235's are fine stock and all.

I'll get pictures up, my mom sneaked in some older pics that I didn't realize so I'll have her send them to me and I'll include them with a current shot!

Pictures:

unfinished hood mocked up.



First picture with new meats.



Nice profile shot with mocked up hood



Scars from an incident with a bent fence post



Little paint picture of how I'll bedline it, had to shade for contrast. I'll probably just get rid of the rear flares anyways, looks funny how it is...

It is truly surprising! It'll look 200% better without the damned pinstripe, and with the sides/hood clad in black paint/bedliner!

I was skeptical about the rims, but they ended up looking good so I'm happy. Anyone know where to get center caps?

Ps: LOVE C&C

Well I registered here the first of 08, so two years counting only me! haha. I've loved them since the release of IKSSE:III, it's still kinda my favorite album, but I went back and love SSTB now, not to mention the newer Good Apollo albums...

Ha, I was thinking of ones that look like they were supposed to come with the Pro-Comps... I got them for free, so I aint complaining about missing them, I'd just like some in the future!

When I started I was 17, now I'm approaching 19... but thanks! Age doesn't matter as much as sheer stubbornness in any case... The only part of this NOT beyond my expertise was the electrical, and even that took freaking forever... I'm not sure how many people appreciate the amount of thought that goes into such a thing...

sawzalled off the ends of the front bumper and killed the lower parts of my front fenders, looks a bit better, but I also mashed a lower control arm mount and drag link, fixed the link, and have a new (super beefy) LCA mount I got from a local guy for cheap, just need to install it.

I also exploded my front (crappy CV boot) driveshaft, does anyone know if an np231 front yoke will fit a 207? I need a cheap solution for now, an AX-15/np231 upgrade is being planned before the year is out.

I'll try to get pics up, might just be cell pics though. disco'd the sway bar and got some flexing pics, it actually does pretty well!

I moved to Prescott, AZ, and now have more places to offroad and better weather to work in, progress will be slow due to getting settled in.
