Ford Sierra box

PostPost by: "Robert D. LaMoreaux » Thu Apr 04, 2002 10:23 pm

I have a sierra 5 speed box fitted to my +2S130, as you say the box will
fit

but the gearstick is approx 9 inches further back and you will need to
cut a

hole in the top of the chassis to accomodate this. I have cut a circular
hole

and formed a flange as per the original holes in the backbone,my car is a


I saw a gearbox that would have the gearshift just about perfectly
positioned for an Elan a while back.

It was a Borg Warner T5 from some small pickup truck.

I did some checking and the '84 Mustang had the same ratios as the Elan
Semi-Close gearbox, so I keep thinking of finding a pickup T5 and combining
it with a T5 from a Mustang to get a 5 speed Elan gear box. The T5 from the
'84 Mustang is good for 265lb-ft of torque and weighs only 75 pounds. There
are other ratios used in T5s, but the '84 Mustang ratio or the Ford
Motorsport T5-A are the only ones I know of that would be about right for
the Elan.

Now I need to find out if there is a bellhousing for a T5 to go onto a ford
Kent block.

The Chevy S-10 T5 trans has the shift lever at almost exactly the same
location as the current Elan shifter position. I have been tinkering with
the idea of getting a CHEAP S-10 T5 for practice fitment behind the Zetec
with standard Elan bell housing. I figured it would not be that difficult
to mate the T5 to the Elan bell housing. Thought a mating plate could be
developed.

I DO NOT KNOW THAT IT WILL FIT. I BELIEVE IT IS DO-ABLE THOUGH.

Working out the clutch and input shaft length would have to be dealt with.
I was keeping my thoughts to myself until I got hold of one to try it with.
BUT since you brought it up I thought I'd chime in. I have not been able to
find data on the ratios of the S-10. I figured that changing ratios would
not be as tough as changing the tail shaft assembly.

Regarding the moving of the gear shift forward on a t-5. I had to do this on my car. I used a chevy s-10 tailhousing on the mustang t-5. I had to rig up a speedo gearing that would work, and used the hurst s-10 shifter with with a shorted gear shift handle.

How close is the bellhousing bolts on a Zetec to the the Ford 2.2L? Ford also used the T5 on the 2.2L Mustangs, so if the Zetec is the same bolt pattern a bellhousing would be available.

My feelings exactly.

I was keeping my thoughts to myself until I got hold of one
to try it with.
BUT since you brought it up I thought I'd chime in.

There I go opening my big mouth. ;-}

I have not been able to
find data on the ratios of the S-10. I figured that changing
ratios would
not be as tough as changing the tail shaft assembly.


The S10 ratios would probably be terribly wide, but some of the Mustang ratios are perfect. It is probably more work to change the ratios since you have to completely dismantle the unit to change the ratios. On the other handif you in there you probably will want to replace the blocker rings and bearings. T5s are easy to work on if you have access to a shop press. I've rebuilt two of them, and they both worked fine when I was done. The early ones are a little weak for a V8 Mustang especially 3rd gear, but in an Elan itwould be understressed. Also the early Mustang T5 had an alluminum input shaft for the through-out bearing to ride on that would wear until the through-out started sticking. Later ones changed the tube to steel.

Still in the future thought stage for me though...
