Hello again everyone...

I have a '79 294 and am thinking of switching from drum to disk/5 bolt brakes. Can I get this upgrade from a 944? If so, are all years compatable? I have access to these and other parts from a local (wrecked) '84 944. Also, are there other parts from the donor car that would work in the 924?
Thanks for the help. You have no idea how much I appreciate it.

The brakes can come from early 944's. 85 maybe 85.5 and older. Your 944 parts car is fine. What other parts from it would you want to put in the 924?

Honestly, Neil, I'm not sure... yet. I can have anything I want from the 944. The only thing damaged in the wreck was the frame as far as I can tell. The engine, drivetrain, tranny, etc. are in good shape and I know the car was a great runner before he wrecked it. I already have the door handles, some interior stuff, etc. I was almost wondering if it were possible to put the 944 engine and whatnot into my 924. I could use the 924 engine for another project if thats the case. The 924 is completely apart at the moment. This has been a total restoration project from the get go. Basically, if the 944 has parts that will work, and are better than whats on the 924, I'll use them. If you have any ideas, don't hesitate to let me know.

The brakes will make for a bolt on swap, as long as you are sure to get the master cylinder and all the lines from the 944, they are quite different from the 924 parts.

As for the engine swap, nobody here has actually done this, but it can be done. You would have to modify the original 924 crossmember to accept the 944 motor mounts, and modify the wiring harness as well. If you have experience in fabrication, or know someone who does, it shouldn't be hard at all. If you don't, your best bet is to take it to a fabrication shop, and have a fabricator do it for you.

You do not need the master cylinder. I put my 1984 944 brakes right onto my 1982 924. I know the 1982s master cylinder is different from the 1980 and older ones. So it might be nessesary to upgrade the older cars. I am not sure about that.

Anyway I have done many panic stops from high speed. Travel 495 in MA and traffic can come to a stand still from 80mph very quickly. I have never had any lock up issues and the car goes straight as an arrow. Man do the 4 wheel vented discs make a difference in stopping power!

Since you have the '79, you may wish to grab the drivetrain to convert to the 944 5-speed; this means, basically, torque tube, trans, rear suspension (just grab it complete) and of course shift linkage. Suspension parts, etc., can all be used as spares anyway. This because the '79 5-speed is subject to a lot of abuse and very expensive to rebuild, if possible at all, due to parts availability. Went through this with my racecar; all it needs is the right clutch disk. Jeremy has also done this. Gearing's not quite as nice for racing as the proper 924 5-speed, but at least it's robust and easier to fix (not to mention, as a 944 part, easier to come by). It's documented in the Tech Section. The rear suspension would need to be changed due to different trans mounts. I trust your car still has the original, dogleg-pattern 5-speed?

Vaughan.. yeah, it still has the original shift pattern.
One thing I was wondering, also, is how much swapping all of this (especially engine) would effect weight balance. Any ideas?

The trans weighs about 20lbs more - but the 924 and 931 was sold in this configuration. You won't notice it; I only notice it on a racetrack when driving at the limit for a good 10 laps.

Oh, yeah, duh, get the hatch too! Bigger wing, and sell off either your 931 hatch or the 944 hatch.

The line hookup at the mc is different on the 944 and the rear lines have to be made longer just pick up a few 3 ft section of straight line that has the hook ups on them already and a tube bender. I installed 83 44 brakes and am very pleased with my efforts. Brake light hook ups might be different so
look into that.

Youll see what lines you have to remake as they wont fit on the mc and rear calipers.

The '80 and up 924's don't need to have the master cylinder changed for the brake swap, but earlier cars might.

Just a quick update....

Been extremely busy lately so I haven't had much time to get on here. I went ahead and just bought the 944 outright. Got it for a little under $300, actually. The damage to the 944 wasn't as bad as I thought it was. Just some damage to the fenders and a little to the hood. The frame, suprisingly, wasn't even damaged. Need to replace some of the parts that were sold before I got ahold of it (in the neighborhood of about $800) and also need to replace the screwed up body parts and everything will be great. Looks like I have two restoration projects on the plate now.
The only prob is that this still leaves me without the 5 bolt coversion for the 924! Always looking, though.
Thanks to everyone for all the help and suggestions. That's what makes this board so great! I'm sure I'll have plenty more questions for you very soon. Thanks again!
