Hey everyone,
I'm new here, so take it easy on me. Some friends and I just picked up a 77 Porsche 924 that has been racing in 24 Hours of LeMons.
it's got a 4 speed in it right now and I have the opportunity to pick up a 5 speed from a 944...
Do I need to swap out the torque tube to a 924s?
Any other pointers or things to look out for?

Thanks in advance. This site looks like there's a lot of knowledgable folks on it.
Hope they're kind to noobs.

There is some information on swaps both on the technical and FAQ sections of this site. A quick look on my part, not sure if it will answer all of your questions, but it is a start.

I am a relative Newby here too, so I don't have a lot of knowledge about the specific questions.

I have replaced the 4 speed with a 5 speed in my 1976 car. I found an original 924 5 speed (016 model). I had to make a dent in the fuel tank with a hammer, otherwise the gearbox had zero clearance to the fuel tank.

I believe that the 944 gearbox can bolt right up to the 924 torque tube, but the prop shaft diameter on the 924 and 944 are not the same......

If you are after performance the 924 5spd is a better choice, the 944 will have similar ratios on 1-4 plus another gear. the 924 is much closer and have 5 gears in almost the same range as the 4 speed. If i remember correctly..

You are right on that, Cédric. RPM's in 5th gear (on the 016 5sp 924 box) are not much lower than 4th on the 4sp box.

I have ano 81 924 5 speed. I think I can ship it via Greyhound. If you're interested let me know.
