EFI Throttle body hood clearance.

DaveBB · #1 (**permalink**) 02-21-2012, 07:05 PM

I'm helping a friend put a 2001 5.0l from a mountaineer into his 73 Bronco. The IAC on the throttle body sticks up far enough for the hood to hit it. I wonder if the throttle body can be rotated on it's seemingly square mounting. Anybody know? Suggestions?

Yes the TB can be rotated.. though your only other option is probably 180deg from the stock position and even then I'm not sure what else you'll have to modify to make the throttle linkage work.

Thanks Conanski. I'll try it and see what happens.

I am not an EFI/5.0 expert(dummy even), however this is a common problem putting a 5.0 in the EB. I believe the cure is using a Mustang intake. There is a difference in the height of them.

Sorry, this comment is more about looks (but it DOES have implications for under-hood mechanicals) ALL EB's were made, just screamin - for a 1 inch body lift. Looks are a personal opinion, but I'm not alone in this one. Many tranny swaps include one as well. I will most likely add it for the 250/4.1 swap-in. Same issue, bronk hoods are low! (No scoop for this 1, the w'shield hasta drop for some of the access trails.)
Let us know how U do, pic R great.

We're thinking about removing the elbow from the plenum and mounting the throttle body there. That's like the Mustang intake I think. There's a little more room under the hood back that far.
Think that'll work?

I'm not up on the "newer stuff" keepin most of the bronk more 'period correct'. Will not ask for more specifics on mountaineer vs mustang vs T-Bird; the years, etc. Scan the 4WD or Off Rd forum on here. Some over there R up on this stuff. One really good referral in ur area is Wild Horses in Stockton, CA. They've been buildin bronks for decades. They have done this install and as a commercial enterprise would advise expecting to build a relationship that may turn into a future sale. I'm sure they got some ideas. Also CB (started by J's Bronk Graveyrd in LP of MI) is a fantastic EB owner's site w/plenty of tech advice by guys who've 'done it'. Build threads, pic, chat n several tech forums...
Bout 30 yrs. ago the PO put a car 170 in mine. It's got 2 dipsticks (1 each side)! It hits the hood (even after all the body has been rebuilt to orig. specs) with out the air cleaner on! I feel yer pain bout the hood clearance on these rigs.
Keep in touch, people HAVE done this swap.

Does your intake have the integrated elbow(top pic) or does it have a seperate detatchable section? If it's detatchable then yes you could remove it and mount the TB directly, this also means you could reverse the upper to face the other direction if it would help.

Well. We got it running. The hood clears just great. The biggest problem so far was finding a shop that could access the PCM and turn off the PATS function. It wouldn't turn on the injectors until we did that.
Now I have another question. We're trying to hook up the cruise control from the 2001 Mountaineer. I found out that the signal from the Mountaineer rear wheel 4wabs sensor goes to the 4wabs module for conversion before it sends the signal out to the places it needs to be. We got a vss that goes into the speedo cable to send a signal but now realize that the signal has to go through the 4wabs module for conversion. The cruise control module has a vss input wire but I don't think the 2 wire vss signal can be used by the cruise control module. I've been searching the net for a signal converter to use but can't find anything. I think gm uses a thing called a vssb or vehicle speed sensor buffer to do this job but I can't find out if I can use one of those. Any ideas?

I took a picture with my phone. It kind of gives you an idea of what we did.

pic's fine. Thank you for sendin! motor looks as low as the fill cap for the break master. Howja finally do it? Upper rad hose & fill for the PS looks too hi tho....
;^)

I think the Bronco already had a 1 or 2 inch body lift because the body mounts look thicker than what I remember. All we had to do was move the throttle body to the plenum not using the egr elbow and rebuild the coil bracket to make the coils lower.

Sure wish I could find a company that makes a vss signal converter aftermarket that makes it so I won't have to use the 4wabs module to get a signal for the cruise control. Anybody know what to do here?

Again, all Greek to me.
Have U tried another (more accurate) forum on this site? another site? (pirate 4X4?, CB?)?
Our buddy "house o deisel" may have info - search the 'member list' here...

If you don't mind me asking...where did you find a shop in Socal that could disable PATS? Seems like most local shops are more schooled in the Mustang 5.0 OBD1 stuff vs. the OBD2 of the later 5.0 Explorer. I'd like to use an Explorer ECU someday with a 4R70W trans under it's control someday but the info I've ran across in the past was that using the OBD2 Explorer 5.0 is uncharted territory. Thanks in advance.

JBA Racing ask for Bruce. I found them looking for dealers that carry SCT tuners which I heard can also disable PATS. SCT tuners cost too much for just that function. They seem like the way to go if you want all the great stuff that thing can do.
