Can anyone tell me about T-5 conversions? Is it worth it? Does it have to cost a fortune? What's the best T-5 to get? Are there adv/disadv to different clutch activation methods?

Thanks!!

These are some great questions. Why, if I didn't know any better, I'd say these are the kind of quality questions that only someone who has performed the conversion could put together in one efficient post.

How about some handy links?

Links are great, but let's discuss this.

Tranny: Find yourself a World Class T5 out of an 88-93 Mustang. World Class means it will hold up to typical V8 torque ratings. Other non-World Class trannies are found in earlier Fords, and v6/i4 cars. I've heard you can use 94-95 trannies but you need a new input shaft. You'll need a new tranny mount, which can be purchased or made.

Bellhousings: You can use a stock vintage 3speed/4speed bellhousing if you want to use original mechanical linkage. If you want to use a cable clutch, you need to use the T5 bellhousing. Either bellhousing will work with hydraulic clutch.

Shifters: I believe a vintage shifter or T5 shifter will work.

Pedals: Vintage pedals need the quadrant welded on if you're going with the cable clutch. I believe some have used Foxbody pedal setups. 64.5 clutch pedals are different than other vintage pedals, but can be modified to work.

Disclaimer: I've not done this mod.....pondered on it a bit...but if someone with real experience disagrees, then I defer to them.

A vintage shifter handle can be made to fit a latemodel T-5 shifter assembly. Usually, a T-5 shifter handle is cut above the mounting flange, and a vintage style (longer) handle is welded to it. I believe several places (NPD for one) sell a new unit that is ready to bolt on.

They actually make a stock appearence shifter that fits the T5 it's about $130. I have a 93 T5 conversion in my Shelby. If you are going to drive the Hwys, its a must. Total, it cost me about $2K.

Just FYI, on mine a I used a Hurst aftermarket T-5 shifter base (left over from a previous Foxbody I owned) and eBay-scored a small-dinero #1406 Hurst shifter handle that bolts on directly and puts the shifter right in my hand.

The problem with stock-appearing shifter options is, to me, they appear, well, stock

Very cool.

That is definately the way I'll go with my eventual swap.

You are correct......here is a link that explains pinion angles in detail:

I thought that only pertained to Tremecs and a non-modified tunnel.

Exactly....If i were to do the swap i would not be willing to modify the tunnel beyond some minor percussion engineering.

Reriveline Angle

Shouldn't be a problem in most T5 conversions, unless you have a poorly made crossmember. I used the Ron Morris x-member, and came up with 3* of tilt back, and a 2* pinion up. Just about perfect. B)

The whole T5 conversion business is really about 4 seperate threads, as there are many routes that can be taken with the bell, clutch, linkage, shifter, pedals, etc....

Since my motor is already a 50oz late-model, I used all late model flywheel, clutch, bell, plate, & fork. No adaptors needed.

Since i didn't have any clutch linkage already, I decided that cable or hydraulic would be good options. Some folks have a lot of trouble with Tri-Y headers and cable, so I just went hydraulic to avoid making any exhaust changes.

I used a 92 T5 that I had to rebuild myself. My preferred option would have been a new T5Z.

I got a Hurst shifter with the tranny. Has positive stops (very important), but the stick was WAY too short. Hurst sells plenty of different sticks, and I found one that's 8" up & 5" back - worked perfect for me. I'll get the stick info together and start a new thread one of these days...

I bought a pedal set off Ebay, and used latemodel pedal pads.

All in all, it was a pretty easy swap. More details are on my webpage.

FINALLY!

My Transmission Swap Pages (Version 1.1) are FINALLY done. I'm SURE there's plenty more content that CAN be added, but it's a start!

If you want to bookmark my swap page for future reference / posting, the full url is: http://www.gt350clone.com/T5%20Swap.htm

Lots of great stuff there Bob.

Looks like I've got some reading to do.

How hard would it be to put in a T-5 into a '69 sportsroof with an FMX automatic tranny? I can't wait to start restoring it, and this is one mod I've been thinking about.

The same amount of work it took Cloney to put the 5 speed in his 65. Read his "how-to" to learn.
