I was looking at a previous thread about someone installing a 60mm throttle body from an escape onto their ranger and I thought this would be a good idea.

But after it was installed on my 03 ranger, it started to backfire and the engine died, so the old one was put back. Now I'm a little stumped about why it worked for one ranger and not mine, so can anyone tell me what might have gone wrong?

 

Did you bore out the intake manifold? I *think* you have to swap the ranger sensor onto the escape throttle body. Other than that I have no idea but am curious because I also want to do this mod.

 

No I didn't. I don't think that the intake is thick enough to bore it out. Then again, I'm not really much of an expert.

 

The butterfly on the 60mm probably isn't opening all the way, if much at all. This link might help. I forgot I had it saved for future reference.

Sounds like air leaks to me. It's not a bolt on -- you have to modify the manifold. Boring it out isn't what you HAVE to do -- creating a correct mounting surface for the Escape TB is necessary.

You also didn't say what year your truck is -- which doesn't help. Do you have a metal or plastic manifold? 3.0 or 4.0? 3.0 I presume since that's who uses the Escape part.

 

I did say the year. It's a 2003 ford ranger. The manifold is made of plastic. All 4 screws on the escape throttle body fit the original holes in the intake.

 

But what about the seat and seal between the two? Yes, the bolts fit, but if it's not an airtight fit, you get problems.

 

Not sure about those.

And looking at the link provided by smash_lizard, I skipped step #4. Does JB weld work best on a plastic manifold?

 

will this work on a 94 3.0?

 

Zach, yes, that's what folks have been using for this mod even on the plastic.

Travis: love your username, lol. Check this site for a lot of information on older 3.0's: http://www.rogueperformance.com and click the rogue performance link on the right to go to a page of many 3.0 mods. That's Fred's page (who is also a member here) and he's been a source of info for us 3.0 guys for some time.

I think the answer to your question is probably yes. There's also a Mustang 3.8 TB replacement that can be adapted and he mentions that over there. I think it's BBK part number 1458, but read the TB mod page and you'll find mentioned in there.

 

Is there anything else along with that that could have made it backfire like that? I really want to make sure before I start gluing things together with that stuff with that. Anything else I need to look out for?

 

ok thanks

 

You must do the step where you use epoxy to fill in the gaps around the intake opening. If you do not do this, you WILL have a vacuum leak. Make sure to file and sand the epoxy down so you have a good sealing surface. You will have to port, or open up, the opening of the manifold. The 60mm is roughly the same size as the outer opening of the stock O-ring type throttle body gasket. The Escape throttle body bolts directly up but you have to modify the intake to accommodate it. You cannot simply bolt it up and go.

 

I'm working on adding a 60 mm Escape Throttle Body. I ported it and added a new TPS, put it on and it worked fine - EXCEPT - the cable going to the cruise control servo is too short! It attaches to the TB great, but it holds the TB butterfly partly open. Any suggestions on how to fix this? I'm considering fabricating an new bracket to move the existing cable connection closer to the TB. It would be easier if someone out there knows how to "lengthen" the cable. Any ideas?

 

Well, I made an extension to the bracket holding the cable for the cruise control servo. Hooking it up in the morning, so I think I will put the 60mm TB back on and see how it runs. I'll post pics if it works...

 

FINALLY! Got 'er done! Got the 60 mm Escape TB installed (and painted blue...went with a Ford Blue look in the engine compartment...) with only minor mods - including porting the TB. Made a thick rubber gasket for the IAC to raise it above the new TB. Did this rather than grind away excess metal on the TB - worked really well. Added a Helix TB spacer - yeah, yeah, I know - waste of $$$ some say, but I got this one on eBay for $20 and it actually works really good. Solved a nagging low idle RPM problem I was having - its now at about 1,000 RPM. Added a Spectre aluminum cold air tube which connects to the stock MAF sensor and air box. Put a K&N flat filter in the air box (again, little $$$ thanks to eBay!). Did the mod on the air box that is posted elsewhere on the Forum - thanks for that cool post, by the way! Painted a couple of things in engine compartment to accent the blue I had already done. I really want to pull the aluminum head covers and paint them blue and also paint the plenum aluminum, but that will have to wait until spring, I think. Oh - the extension to the cruise control servo? Worked great. Here are some pics for ya"ll...
