Bolt on Throttle body info

[solo92s10]

I said I would do this a little while back so here is some specs and pics of three of the oem throttle bodys that will (some with slight modification) bolt onto the svt. Hoping maybe some other members will contribute some info on aftermarket tb's as well, such as csvt49 with his 75mm bbk tb. I believe it was understood on here that the F150 tb was a 65mm tb but as you will see that is not the case.

First up is the CSVT throttle body- 60mm butterfly plate with a 63mm inlet and a 60mm out. Comes stock, Not much to say about it as it is what comes on the svtc.

96-04 4.6L Mustang Throttle body- Also found on some mid-late 90s crown vics and town and countrys with the 4.6l. Can be found for $25-$50 Used. They have a 65.36mm butterfly with a 68.5mm inlet and a 65mm outlet. This throttle body requires a bit of modification to work with the svt throttle linkage and clear the intake manifold. That info can be found in THIS HOW TO .

97-03 5.4L F150/Expedtion Throttle body - Can be found for $20-$50. They have a 70.48mm butterfly with a 68.5mm inlet and a 70MM outlet. This throttle body requires minimum modification to work with the svt and the throttle position sensor is the same as the svtc. Also this is larger than the svt intake manifold inlet so a little porting may be benificial. This is probably over kill for a 2.5L but for someone with a 3.0L and a tune it could yield some cheap hp. Though there is not much history of this throttle body being used but a few have i believe.

Pics are from left to right. SVTC, Mustang, F150









In short.
SVTC - 60MM
Mustang- 65MM
F150 - 70MM

I used a BBK 70mm from a Mustang application on my 3L swap. Used an SVT throttle shaft (slightly modified) because the BBK throttle shaft was cammed differently and didn't quite fit the linkage right even after I had modified it.

For the larger inlet sizes, do you need a new accordion, or can the stock unit stretch out enough ?

I've got an F150 TB the stock spring on it is way to soft so I added another on to help out with it which made it better. Also you can use the stock accordion tube but I wouldn't.

If the stock unit isnt a great idea, would the BAT, Inc. part be a better match ?

BBK 75mm Part# 1703 (Power Plus BBK Performance Throttle body fits all 90-95 4.6 2V Applications - Also 1997-03 4.6 & 5.4 F150 & Expedition Models.)

-Can use OEM TB bracket (to use on the ST220 UIM I had to create my own bracket using the OEM brackets from both the ST220 and the SVT)
-the OEM cruise control cable is slightly to short and holds the TB throttle plate open a hair. I have not yet addressed this issue.
-BBK TB comes with a new TPS sensor. I currently have the new one installed, but can not comment as to whether it will work with the OEM tune.

Picture of bracket I made.

Required material removal for matching on ST220 UIM, would be similar for 2.5L UIM

Installed

If you were responding to me, I apologize, because I was actually asking about the accordion, not the throttle body itself.

Nope, just providing the info for the thread.

However for you question... No it won't stretch. You'll need a couple of couplers and a tube to make it work.

I have been following the how-to, using the 4.6L intake in this How-To:

http://www.contour.org/ceg-vb/showthread.php?52906-65mm-Mustang-How-To

However, about 1/3 of the pictures at the end are missing. Does anyone have these ? I PM-ed Harry, but he hasnt posted in a year, so I doubt he will get my message.

thanks,

Mad Dog

Bump. Anyone have the missing pictures from the original How-to ?

thanks,
