Okay guys I'm going to try to make the most complete build thread I have ever made to date with lots of pictures and such.
I'm waiting for my ride to get back then I'm picking up a fresh clutch for the M5OD trans and wading over to my cousins pole barn to complete the swap in 1 day!!!
I know...
Ok so I'm moving my build thread from the b2 area here to get a little more traffic and insight from the experts
So here is the build plan,
Starting with my 86 bronco 2 it's got a 90 4.0 and dash and front clip
It does need a little tlc, and I'm working on that
I'm keeping the 78-79 axles...
There is two ways gas could get into the oil
The first and most likely is the lower intake manifold gasket, although if this went, I would think you would have coolant issues as well, but i guess it could happen
The other is that your rings are shot, and a combination of bad spark could allow...
I'm not running ac or a auto trans
so my question is , will the 2.9l radiator hold up behind the 90 4.0
I know the warmer you can run your engine the better fuel mileage you will get
I have the 2.9l radiator in now, but it has a pretty big leak in her so I'm always adding coolant, I'd like to...
So I finished my 4.0 swap in the 86
I have just a few minor problems
First the bigger one
She starts up cold like a bat out of hell
Once let her set and idle she will idle for about 15 mins until she gets good and warm then she just chug a chugs and does out
When I try pushing that gas it...
What I want is full size axels under my b2 I've seen a few with full size axels and some lift and I love the look.
I'm up for anything I know there's going to be some cut and pasting
I also am looking to get 3-6 inches of lift..
I've heard of using early bronco axels,
But I wouldn't mind a...
Starting my build thread to give you guys some motivation to do your own 4.0 swap
!! Here's some picsstarted ripping her apart
the first gen front end is going bye bye.
the old 2.9 is coming out
its out!!
So I think I have the basics covered
I've done this swap once before in a 89 b2 so it was a lil easier then this one is gonna be,
I have a 86 b2 made 10/85 2.9l efi
The donor is a 90 ranger 4.0l I'm not sure if it is auto or man trans I'm guessing auto, I know the harnesses are the same I had...
I've never seen this clip or had to do this before and you can't really get to it, and I don't want to break my speedo cable.. I already broke the clip, here's a pic, what's the secret??heres before I broke it
N after
Okay so finally got the beast road worth but their is still a few hiccups.
86 b2 man trans 2.9l efi
Put all new motorcraft spark plugs in yesterday, it ran a lot better after that, wires looked visually appetizing, so going to wait on those for now..
But...
She doesn't want to start in the...
This is my first b2 with a manual trans case, it's the original in the 86 although it was built in 85..
When I bought it I asked if the 4x4 works he said there was a belt that was broke in the t-case?? I was thinking belt?? It's a ford not a Cadillac, lol what I think he was talking about was a...
so i have a 1986 b2 500$
picked her up last friday
she was sitting for 10 years
i got the mouse nest outta the intake, unstuck the throttle body, and she fired right up, after i put a new ignition lock and tumbler in.
i backed her outta the drive and went to hit the brakes and they went...
