I was able to snag a T5 out of an 88 4cyl mustang for 200 bucks. Couldn't pass on the price. Need to know if I need to changes to it's gears or the gears in my 66's rear diff.

Also would love to know other pieces that are needed to swap from my c4. I found this site Modern Driveline - Catalog search ... T5_kit.htm where I can piece together a kit but out the door is over 1000$ which I am ok with but curious on other ideas.

Thanks,
Adam

That is a great swap. The gear ratios should be fine. FYI, the gears are exactly the same in the 4cyl T5 and the V8 T5. The difference lies in the input shaft and it's attached gear. That changes all the ratios. I assume you have no bellhousing?How do you want to handle the clutch?cable? mechanical?

Correct on the no bell housing but thought I read somewhere a 3 speed will do just fine. Also I read the cable setup was much nicer. That said I am going into this knowing nothing so I am completely open to suggestions and ideas.

I have a non-world-class behind my 200-6 in my '65. Very good setup.

What rear end gear do you have now? I have an 8" with 3.25 in mine.

Modern Driveline are quality people with quality well engineered parts. They will talk you through all the parts you will need.

My car was already a 3-speed so I used the z-bar clutch already in it. But, we have put both hydraulic and cable clutch linkages in early Mustangs. Both work well.

VIN tag read a 3 so I assuming the final drive is a 3:20

Thanks for all the suggestions. I sent an email off to modern drive lines. Will go from there.

I did the exact same swap well before I went turbo and it was the BEST thing I did to the car.

This comment made me a little to excited about this project. Thanks irate:

right for the most part, wrong on the gears being the same. the four cylinder T5 has a 4:1(approximately) first gear ratio, where as the V8 T5 has either a 2.95 or 3.35 first gear ratio.

as for the bell housing, there are kits to use either the earlier 2.77 bell housing, or the later 3.03 bell housing, just note which one you buy, and then buy the proper kit along with the proper flywheel for the bell housing. this of course assumes that you have the dual pattern block, most 66 and up blocks are dual pattern.

here are a couple of threads you can peruse that have good information on the T5 swap and some good clutch information, especially for the smaller 8 1/2" clutch used on the 2.77 trans. i hope you can read them, some have had issues others havent, let me know;

Thanks for the great links.

I was able to locate a 67 I6 with a 3spd toploader in it, I know I can use the bell housing and fork but what about the flywheel? Could I snag that and have it turned as well?

Thanks

If your engine is the 66-up style with the dual bellhousing pattern on the block, it will work perfectly. The manual bell, flywheel, and clutch plate were the same 66-70. You'll need the 67-70 disc, with the larger spline pattern, of course.

The car was built in in April of 66 so I assume it has the dual pattern but that is great news. I'll grab the flywheel as well. irate:

Will I need a different starter? Thanks for all the help everyone.
