Hello All!

I just bought a 1972 Spitfire. Only owned by two people since new, and garaged for the last 30 years. It has a little rust, and the brakes are a mess and it has 100810 miles on the clock.

I'm testing the compression this weekend, but don't expect miracles. I anticipate a rebuild, but I would like to drive it and rebuild another engine. I am not interested in a engine swap, such as putting a Renault Twingo engine coupled with a Ducati Monster transmission....spinning smiley sticking its tongue out I'd just like to put another Spitfire engine in. I know that there have been a lot of articles about engine swaps, but I can't find a forum post that shows which year Triumph engines will fit which Spitfire. Looking at the motor mounts and such, it seems like just about any engine/transmission will fit any year. But I need a seasoned Triumph person to confirm or deny.

Thanks so much for your help.

Take the time to consider what you want. For example personally I would first want a small journal 1296, then a 1500. EU setup for either. I would want a single rail J style overdrive gearbox. Oh! Wait! That is the setup I have (1296)

I had a 1500 EU setup in it and had the 1296 rebuilt while I drove it with the 1500.

Look at the telergizer site for the advantages of each.

Jake,
Thomas is right, but it is simpler to do if the engine and gearbox are from the same year Spitfire. Or at least not too far apart. Mixing and matching doesn't go as smoothly. Things would go easier in your case with a 1971 or later drive train.
All the best,
Paul

Midget 1500 motors and trans will work also; not the 1275s though (notice I didn't say 1296)

Early gearboxes (those with non-sycro first gear) will have a smaller companion flange and won't fit up to your drive shaft.

True, but since the UJ themselves are the same size for all years, it requires only an early UJ flange to remedy, not a whole driveshaft.

Is your transmission good? Do you plan on keeping it?

If so, I would specify what engine you plan/would like to use and we would suggest what you need to do to make it work.

If you plan to change the tranny also, it is easier to fit as a pair.

Kieth,
That is the main thing I had in mind when I posted the suggestion of sticking with 71 and later in post #5 of this thread.
All the best,
Paul

Jake,the later single rail transmission will reuire a different drive shaft. They are a different length.
Just so happens a friend is getting rid of the whole Spitfire drive train on it's frame with brakes and good tires.
I'll see what he wants if you are interested. It all ran when we just used the body for his CGT6.
A little road trip, did it a few years ago and it was a little over 500 miles round trip.

500 round trip? Sounds like a good deal. I drove 1000 in a day to get a small journal crank motor. That is mated to a late J type OD, in a ‘72 frame. It all fits.

Paul,
Carter is correct in that the U-joints are the same so an early U-joint flange would mate the early gearbox to your Mark IV.

if your doing a swap this is the way to go. Small j motor will give you years of pleasure.
