Can a 944 turbo engine be bolted right into a 924s? Would it require mods to the tranny? Or would it just drop right in?

u'd have to change the tranny too...and when you want to do that...you need to unmount all the suspension(yes the rear too) and since you are doing that you must change the brakes while at it. Also...might be a good ideea to re-index the torsion bars. Its a good 3 weeks job for you and a friend or around 1-2 weeks for a shop.

I just realized this is not the right place to ask this question. Newbie mistake, sry folks.

To bad its a big job, a 217hp 924 would probably scoot pretty darn good.

Are you talking about a 924S 2.5 liter? If so, it's the same block as the turbo....

No actualy is not the same block(the 951 has a reworked block) but its not the problem when swaping.

Well dont worry the 924 would go about the same as a 951 would. because when you change the engine tranny and brakes you add more weight and you end up about the same as the factory 951.

We have a board member here who boosted a 944 using an eaton supercharger. Maby he could help you get out of this power needing situation.

The casting of a 924S block is the same as a 951 as far as I know. I agree that it has different pistons, etc, but I see no reason why it would not bolt right into a 924S with no change to the tranny or torque tube. You would need to swap out the motor electronics and the entire exhaust system, plus add numerous components such as the heat shield for the turbo, the cooling system for the turbo, etc.

Correct me if I'm wrong.

The 951 engine will mount up to the existing bellhousing and will still work with your existing transmission and clutch mechanism ( you will need to use the 951 pressure plate and friction plate though). You will have to change all the stuff that Paul said and decide how and where to mount the intercooler. Electrics wise everything will work if you use the complete 951 engine loom and correct ECUs, but as the dash clocks are not interchangable you won't have the benifit of the boost gauge.

Early 951 (UK spec and possibly ROW) brakes will bolt straight up to your suspension but you'll probably want to check wheel clearance with the bigger calipers if you have the standard 924S 15" wheels. If it was my car and the 951 engine was complete with all the bits and at the right money I'd go for it, good luck and let us all know how it goes..............

Cheers, Bruce.

I'm just gonna buy a 931 Turbo instead and mod the boost and add an intercooler if I want more power. After thinking it over putting a 944 turbo engine in a 924s seems like it will only live as a dream... and a somewhat pointless one at that. In retrospect not such a good idea.
