5.0 ho tj engine conversion

I have had a couple of requests for prices and time length... so here is everything that i had to do.......


( also the 5.0 is an efi engine .... the 5.0 HO is a full roller version of the 5.0 efi... minus the rocker arms.)

First I found a complete 5.0 ho at a junk yard out of a lincoln mark 7....

then I got a ford 302 bellhousing and an adapter for the ax15 transmission...

I should have bought a painless wiring kit but I am stubborn and did it myslef

Tore down my jeep now

pulled the whole front nose clip and engine...
put the adaptor on the tranny...
and then the bellhousing.
hammered all the seams in the engine compartment so that the engine would fit.
I used a ford 3 prong pressure plate and my jeeps clutch disc -- use a chevy 11 inch disc.
I also put on a 2.5 inch body lift to help this
bolted the bellhousing to the engine and layed it where I wanted it to sit...
Made the motor mount brackets myself....... straight off of the upper control arm brackets..... just a straight piece of metal to and a flat piece of metal... easy to fabb
sat the engine in and then the hard part...........
...............wiring.................
2 weeks figuring this out..........
total of like 10 wires to connect................ stupid me.....
then exhaust was crazy,,, drivers side is over the tranny.... thanks to the body lift..... to a 3 inch exhaust and a meanstreak muffler.
slave cylinder I made my own bracket, and used a chevy 4.3 slave cylinder.....

I also used the stock radiator .... works just fine.... You have to run an electric fan ..... my personal one is off an 87 ford taurus.... 120 amp fan....

Now with my bracket I used for my clutch I had to have a suspension lift of at least 6 inches........

but After I re did it I could probably use a 4 inch lift ... but I like mine.
You see I never wanted to be this big



prices

engine- 650
misc stuff that i can't think of - 300
adaptor - 350 for rush
bellhousing -90


So in all I spent 2000
and that included 500 bucks I spent for the shop I kinda rented.

It took me about 3 weeks total to get mine done... but if you have everything and have the time I would say about 2 weeks


tools

torches
welder
sockets and wrenchs
manuals



I may have forgotten some stuff so any questions let me know

tj/5.0 swap

Nice work. I've been contemplating the same swap in my '98/2.5L--can't stand not having any power!! I was wondering how your tranny is going to hold up and is that the same one Jeep used for 4.0L and the 2.5L? My plan is to use the 302/AOD from my Grand Marquis and either get ahold of a Ford t-case or get an adapter for the NP231. See, I always thought the trans behind my 2.5L was way too weak to support any V8. Although, the way you did it seems like it might be easier. Also, any tips on the wiring end...not looking forward to figuring that one out. I have all the wiring, computer, etc. from the 'Merc and I was hoping to use it instead of going the "Painless" route($$$toomuch$$$). Oh, about your body lift...was that necessary and did you have to go 2 1/2 inches high?

Thanks, I'll let you know what I do.

Well I have the ax-15 with the 231 transfer case... and I broke a driveline and a yoke... and when I thought I took out my tranny it was actually my throw out bearing... and I pulled my tranny apart and found no metal shavings... And I am very surprised to see this tranny hold up so well.


Now if you want to do this swap stout...

5.0 ho engine
t-18 transmission
and a 205 transfer case

bombproof setup

all ford and your pumpkin is on the left side drivers

I did't expect to find a 5.0 TJ guy...

I was starting to wonder if I should get too deep into this project since I hadn't seen anyone else doing it. Any regrets? And do you think you would go with that T18/NP205 setup if you did it over?

Which Fords came with the T18(I don't even know if its a auto or manual) and the 205? I'm guessing its a manual out of an F150/Bronco, and also which years?

I was considedring using the AOD but the adapter is $640.00.
and you can find a complete drivetrain that will work for less than that.
I found an np435 with an np205 complete for $200. Keep you eye out in the local trader papers

I still plan on putting a t-18 manual transmission --( 4 spd granny low ) to a married 205


just haven't had the time to put it in.....

Also if you do an automatic..... I would go with a c6 just cause its a strong tranny... You should be able to find one married to a 205
way stronger and cheaper than a 231...



try to find a 70s ford to get these parts from,,, and bring a ford tranny number book if you junk yard hop... t 19 looks just like a t 18 -- only difference is the gears

jeep t 18 have a long shaft, not good for us short wheelbases

Yeah the ax-15 that I have has held up pretty good so far...

And I have around 325 horses pumping into it

I would stay away from the aod tranny they suck the stock jeep trannny is stronger then they are. not to mention fixing anything on an aod would be spendy. I check prices on them and its a joke. On my 302 swap I went with a truck 4 speed out of an 84 ford bronco. T18 tranny and the np205 transfer case off the same vehical. fits fine.

Ford fan??

I know from being familiar with Fox Mustangs that the AODs in a mustang can handle gobbs of power. Depending on how much power you're putting through it, that trans can be built to handle it.
But anyway, for my application, my motor will probably only put out around 200 hp (initially). I'm still researching my options, but I still think my AOD will be ok--and most likely aquire a Ford t-case instead of the adapter/231 deal.

If you go auto I would recommend getting a C-6 tranny......


they are pretty strong and would handle the abuse of offroad

but if you pavement pound then the Aod is a good choice,
Even occational offroading would be a load on the aod ... seen many a broncos go through those trannies...

price what it would cost to get that aod rebuilt.. then price a manual


aods are super spendy....

the c6 tranny is really long your drive line angle might be pretty short with a c6 . If i was to go with and auto I would switch over to a chevy 7004r tranny. ITs as short as a t300 and stronger then a t400 and its a 4 speed tranny with a locking torch converter. you can get them with both driver side and passanger side droop tranfer cases. and advanced adaptors makes a bellhousing adaptor for them to mount to the 5.0 that would be my choice for auto. oh and deffently need to go wheeling next time we get together Josh

I see your point about the aod. If I go through all of this, I wouldn't want to worry about my tranny breaking.

Did you(s) retain your original driveshafts or at least the same lengths? I've been told when doing a swap to start at the t-case mount so your driveshaft lengths don't change. But then I suppose the overall drivetrain length is the most important.

Oh yeah, I remember a c6 being on the long side. Seems like it would be too long for a jeep.

...you answered my question before I sent it out...

I think I'll look into getting a t18/205.

my rear drive line lenth changed on my convertion. the drive line accually Is longer now with the convertion. the front drive line is just a little shorter then it used to be. and with the np 205 tranfer case it already has the slip yoke eliminator on it. so i was able to put on a better drive line.

Very cool. I have a 89 5.0 H.O. that I hoped to put into my 81 CJ7. My problem is that I am in So. California( No, I'm NOT happy about it) I lucked out and got the complete wiring harness and computer and everything I need for the smog caca. Now I just gotta do it. Your post will be helpful. One question....how did you handle the fuel injection pump? Did you get a new fuel tank or find something aftermarket? I haven't researched it that far yet. Any one got any input?
Thanks.
