Default 924 w/ 951 motor, some questions?

Well my garage has had more than its fair share of cars this year (3 951's, 1 968, and a VW) but with the 968 on the way out an interesting option presented itself recently; a local guy offered me cash plus a 924S.

Anyway if this works out I would have my 951, this 924S, and a 951 parts car (mostly complete, sans brakes front bumper and rear body work), so just as thoughts of the 968 turbo came to mind (but for cost reasons it wasn't going to work out) now thoughts of a 924 w/ a 951 driveline come to mind.

I know keith was doing something of the sorts, but I know he hasn't had the time to really get into any of the motor issues.

So what sort of pitfalls would I run into? I know the motor / transmission / etc will fit, thats not a problem, the IC would go under the stock header pannel w/ 924 Turbo vents (or something of the sort). But where the problems come in would be with the wiring.

I have a complete 951 wiring harness DME / KLR so that will help, but I'm sure there will still be issues.

Anyway the 924 is an 87 w/ the sun roof delete car so i'm thinking it would be the perfect starting ground for this sort of swap.....

Yes I know the 951 is more than just the motor, brakes / suspension would follow.....

Just for jollies what's the weight difference between an early 944 and 924S. I know the early 924's were always lighter. Does the 924S have the later offset and control arms or did they stick with the early parts just like the dash? Personally I like the 944 bodies more but a 924S sunroof delete is quite a find.

2765 base weight for an 87 924s

2765 lbs minus sunroof should drop it down even more...a 924/951 conversion should scare a few on this list. Dropping 300-400lbs from a 951 does wonders for the 'Oh Yeah' factor.

I know the 951 motor would add a little weight to the 924S, but I do think with the sunroof delete, and a few other things I could bring the weight down to below that 2765 mark.

it would be great but just remember that the early interior is somewhat of a compromise from the 968....

You know, you're right about the 951 being more than just the turbo, but I think it is utter BS to say it isn't worthwhile to do a swap like this. Especially considering you have the entire motor, wiring, etc.

If you think about it from this point of view, the 924 Carrera GT had not much more in the way of suspension and nothing more in the way of brakes and made about the same bhp as a stock 951. So why then do people like George B and others insist it is such a waste of time to do one of these swaps. And if it is such a waste of time and money, then is it also a waste for guys with really old 911s to swap in newer motors, etc. like you see and read about all of the time?

I say go for it and then you can slowly add differnt suspension later and if need be swap in the front suspension off an 86 951 so you can add better brakes if you really think you must.

I do know the early interiors are not quite as ergonomic as the later ones, but I don't mind the early dash.

But the dash is one of the items I have not figured out yet. I have a complete late interior, and getting the 951 DME to work with the 924 cluster could be difficult. So if I can't get the early dash to work perhaps I could swap over the 951 interior as well?

Its all speculation right now.

It is do-able from what I have seen. I know somebody recently over on 924board.org was trying to. I think the hardest part is finding everything. I also seem to recall you have to do something with the windshield (convert it to flush mount?) but if you have it all already you are most of the way there.

I would ask the guys who has done or tried to do the conversion. I think that will tell the whole story.

Other than Keith, whom has tried this?

I will hopefully get in touch with keith in the not so distant future, to see what he has to say.

the 924 has the speedo reading from the front wheel...you would need the trans swapped-which you would prob. anyways, but then you would need the late speedo, in the early dash or the whole late dash...whoA!

Hey, I'm not saying it will be a snap, but it will be a nice sleeper if you keep it kind of low key cosmetically

Why not just bolt the 924 body panels to the 951 parts car? I didn't think that the chassis itself was that big of a weight saver. It seems like it would be less work to put some of the lighter weight body parts, delete the sunroof with a fiberglass panel, and remove the non-essentials. I think if your start to migrate all the 951 stuff over, your adding the extra weight right back in.
I'm just speculating, I don't know for sure either way.
