I tried searching but can't find any good info on whether it has really been done. I own a 92 b2200 and just picked up a 2004 explorer with a 4.6 4×4 with a blown tranny from a friend for free. Im looking for some solid answers if it will fit. Hate to pull both motors and find out later it don't fit at all. Thx

Also ill be adding a t45 tranny instead of the auto that it came with.

 

A 5.0 L V8 will fit, so I imagine a 4.6 L would too.

I would take my tape measure out and start measuring just to be sure.

 

It's funny I can't find one picture of a b2200 with a 4.6. I would think it would be semi-common since they are everywhere now. I wish Mazda trucking was still up probably would have found my answer there.

I just did a full rebuild on the 2.2 and the transmission. Barely got it running a few days ago and now I got a 4.6 in my driveway. Fun times.

 

Got the tape measure out. Motor measures 30inches wide. Thats valve cover to valve cover. Issue i see so far its very close if not over the master cylinder. Going to pull the motor next weekend and go from there. Hopefully i can find some info somewhere or from someone.

 

This guy got a 1UZFE Toyota/Lexus engine in his B2200.

 

The 4.6 is a WIIIDDDE engine. I bet you have problems with the steering gear and master cylinder/brake booster.
Those valve covers are sort of big...
A Ford 5.0 is almost a drop in.
There is a guy in Louisiana that had a B2200 running low tens at the 1320. It had a small block Chevy in it. I looked at it many times - looked like it came from the factory. He said it was an easy swap

Free is really great, but sometimes it is more work/trouble to install a free engine than it's worth.
Don't misunderstand, any engine can be made to fit... just a matter of how much work it will take.
Good example is a Morris Minor with a big block Chevy jammed into the engine compartment.
Cut car to pieces, build entire new front end, cut out firewall, reconfigure steering, brakes and cooling, place engine carefully - then go fast … in a straight line.

 

Not to mention that for a V8, the Ford 4.6 L engine was a dog.

 

Think I'm going to throw away this toilet paper idea down the drain. Ill keep the engine for now but I'm better staying on course with the 12v turbo set up. Already have the turbo fmic and manifold. Just need to get car smoged (CA) than start the turbo build.

I'll post some pic up tonight. I know we all love pics.

 

here is how she seats right now. Doing some drop spindles and all ball joints replacement.

just installed rear 3in drop leafs new shocks.

 

Where in Cali are you?
Good idea to not get into that conversion.
Also... a few other considerations
Oil pan. I don't know how it is shaped, but that could present an issue.
Exhaust manifolds or headers...

Setting up a turbo isn't all that easy either.
Once you have all of the piping and intercooler done, then there is tuning to deal with.

I am guessing there is someone out there that has developed hardware to interface with your Mazda ECU so it can be reprogrammed.
Even on low boost, you will need to remap the timing and fuel maps.
If your engine is pretty much stock, you may want to limit boost to 7 or 8 lbs to keep the grenade from going boom...

Pix are good. Keep up the progress!
