5sp conversion

[Douglas]

Hello folks. I’m about to put a 250 Spitfire in my driver. Looking for 5sp conversion info please. Looking forward to the help. Thanks.

Are you looking for what will work and who provides a 'kit' or do you have a general transmission already at home or in your mind to use.  There are a number of people here who have tread this path and have posted here on the forum.  You could read a lot of data using the search parameter of this forum but type in "5 speed transmission" as your search criteria....grab a drink and some potato chips, going to be lots for you to look over.

I installed a T-5 and a Desoto 25" engine in my P-15. Follow the link below for photos of how I did my T-5 install

Thanks for the reply and I like drinks and chips. No tranny yet, engine is on the way. Want to keep the 6v system so would like to be able to use the starter. I’ll do some digging. Thanks

Great, thank you.

Other options besides a T5 orTKo 5spd,

 

[Young Ed]

Check out Paul Curtis. He makes an adapter kit that should get you where you want.

Be aware that certain NWC T5s have a terrible gear ratios like a 4.03 1st gear and only .86 5th OD.

You will need an S 10 NWC T5 if you hope to keep your bench seat as the shifter is mid point on the trans.

There are better gear ratios and spreads, but be aware and know what you are getting before you install it and OOPs I'm shifting from 1st to 2nd gear before I'm across the intersection from a stop light.

I will agree a T5 is easier to source than an A833 Overdrive, but it is no where near the trans an A833 is in ruggedness and quality....

Have a good read here ,

Thanks. I have seen all the different ratios with the t5 and have looked into the A833.  Hmmmm

All things to consider, availability is the big 1 in any case, good luck whichever way you proceed.......

Contact Dave farewell at vintage metal works 330 322 3102 he makes a nice kit that uses the stock clutch linkage and flywheel. Do your homework before a t5

[wayfarer]

...and once again I'll mention Rober Horne's swap using the Ranger 5-spd swap that can be done easily and no doubt for less money than the t5.

what transmission goes with that kit? I'm using the stock clutch linkage and flywheel in my T5 swap also. The only parts that changed were the pilot bushing and the clutch disk itself. 

[Don Coatney]

Using a P-15 flywheel and bell housing on a long block flat head crankshaft will create starter to flywheel gear mesh issues but the fix is easy.

Give Dave a call. I used an early Camaro 5 speed but s10 and Astro van and consider speedo hook up getting hard to find mechanical speedo transmission but I used a fellow out of Washington state to convert my electric drive speedo back to mechanical. Dave's a nice guy. I thought it was the simplest kit I looked at without changing a lot of other things

My swap is in a truck so it's a different animal however still good to know of other options. Also good to hear there are options for the electric speedo drive as my spare T5 is one of those.

I used this kit as well and recommend it. The install was easy but you have to have the bearing retainer on the transmission and the throw-out bearing holder turned by a machinist for clearance unless you can do that type of work yourself.

There is now a company that makes a system that uses GPS to determine the speed and then drives a box that turns a mechanical speedo cable at the correct RPM to give you the correct reading.  That's nice, because it takes both the transmission and the tire size out of the equation.
