First of all hi everyone
I'm a frequent reader of rennlist but to my shame i must admit i have never visited the 924 part
I just got a old 924 from someone and prolly acces to a 951 donnor car.
I used the search but i couldn't find any threads on the swap.
IS it even possible? I recently saw pics of a nice gts over at http://www.ttt-motorsport.de/ and started dreaming.
A 924 with gts kit and a 951 engine *drools at the thought*
If there is a thread or a project that has been done could someone post me a link.
I know there's a 924 with a 968 engine and a s2 tranny on here from a lister.
Any pm's about projects or thoughts are welcome
Thanks guy's

They didn't use a 951 engine, btw. Its a 3 liter either from the S2 or 968 that they turbo'd. Hence "Der 3L- Turbo"

Euhm i ment that would be my dream
Anyone know if its ever been done ?

The place to ask would be the engine swap section of www.924board.org. I do think it's been done.

That would be a pretty cool car but you would have to be sure to update the breakes and suspention to handle the added power and speed.

the 924 S came with the same motor as the 951, just less turbo, plus compression. ive got a donor 924 S in my yard that ive got plans for the same thing. bit easier with an S starter but with the early 924s it shouldnt be a problem. would yeild better results aswell, the early cars are a fair bit lighter for some reason.

Trying to properly turbo a 924s motor is a complete waste of money. You're better off lighting $100 bills on fire in your front yard. The differences in the 2.5L na and Turbo motors are not as minimal as you think. On the short block side they're close with only the pistons, oil feed hole in the balance shaft cover, an oil return in the pan, and the oil cooler are different. Pretty much just the block crank and rods are the same.

On the rest of it the "add-ons" are a bunch.

Cylinder head - 951 has ceramic exhaust port liners, sodium filled exhaust valves, different head gasket, and a different cam.

Cooling system - different block-off plate for main pump, added auxiliary pump, different coolant reservoir, different radiator, different coolant x-over pipe, different coolant return neck, an additional hard-pipe, and probably a few other things I’m forgetting.

F/I – The turbo has a different intake, t-body, added knock sensor (not sure if the Na had one but I don’t think so), different AFM, larger injectors, different DME & added KLR (which means you need a new harness), bigger fuel pump, and a different vacuum system.

Beyond those items, you need to pick up a turbo, intercooler, turbo piping, BOV, headers and x-over pipe, down-pipe, test/cat pipe, possible cat-back (not 100% sure on this one) clutch, drivers side motor/turbo mount, a half dozen heat shields that aren’t on the NA’s, oil cooler and lines, as well as a few other things.

The best thing to do is find a wrecked 951 and use that as a complete donor car and sell the NA motor complete to off set the cost. Even if you picked up each item on e-bay you would still be way over the top cost wise. You could also pick up a complete 951 motor for about 2K that has everything on it. That would make more sense financially.

Swapping a 951 engine into a 924 was discussed in an article that appeared in Excellence magazine back in 1999. If I recall correctly, it entailed major fabrication to attach the engine mounts, new mounts for tranny and exhaust, not to mention upgrading the drum brakes to discs and all the extra fuel and electrical lines that had to be run. Their conclusion was that although it could be done (they did not actually build it), hiring someone to do it would be cost prohibitive.

Fast forward to 2006 when good 951s are costing $10K-$15K, it hardly seems worth it. Not to mention the question of how would the old 924 chassis handle the extra torsion forces of all that extra power and weight. Remember, even in Euro trim the 924 only put out 125 hp. Keep the 924 as a 924.

Perhaps it would make more sense to put 924 rear fenders with GTS flares on a 944T

Hey Tom,
I agree 100% with you. In fact, I made the same comment over on the 924.Org board well over two years ago.

Hey guys.. i used to own a 78 924 .. i scanned in the schematics of the two chassis (see link below)... I'd still like to do it, just for the fun of it and/or whenever I run out of other crazy ideas or come up with a lot of time/cash - which will probably not happen for a long time....

I'm going to install a 2,5 litre 16v turbo engine on my wifes '83 924 NA (it already has 5lug 4disc brakes), so it will be kind a 924 GTP I use regular 2,5l block /w 951 pistons+rods, s2 head (waterchannel mod required+different head studs, cam gear mod also) and VEMS engine management. Engine will be complete next spring.
Mods required includes 944 crossmember and fabricating mounts for it, 25mm 944 TT and 951/s2 gearbox (mountings ARE the same) and hydraulic clutch conversion (not too hard, btdt).

Hi, i'm in the end of a 951 swap in my 924s ... engine is runnig i need few thing to finish to take the road...
