924 engine swap?

[Hogger]

I can't find any info on this, and that may be my answer, but would a Porsche 924S 2.5l engine mate up with a stock 901 tranny with side shift?
Would it be a direct swap, or an expensive custom job?

Expensive custom job.

I believe the length of the engine is a factor as well; it might require moving part of the firewall to even get it to fit in the engine bay. I know this is needed with 928 swaps, and I think I remember reading that the 944 and 924 motors offered similar fitment problems.

Darn it! Well I guess I'll keep looking for options, and keep the 4.3l on the table.

Look into a Subaru engine conversion!

Someone needs to do a 4.2l audi V8 swap. The weight and dimensions of the ABZ engine seem perfect for a 914 and the motor bolts right up to one of the cheap Audi A4 TDI gearboxes that can easily handle 400hp+ and gobs of torque. Above average fabrication skills would obviously be needed to make it all work, which is why I daydream about it instead of doing it myself, but it would be a great conversion.

What are the advantages of a subaru engine over, say a chevy 4.3l?
I haven't looked into a subaru, but do their flat engines need modifications to the 914 mounts?

[Dave at Pelican Parts]

They do not bolt up any better than the SBC does. The advantages are that the flat layout keeps the CG lower, most of the Scooby motors are fairly light, and they make noises that are in character with the original motors.

I'm doing an Audi 1.8t swap right now. Should have it running by next Spring. I have a FWD 5 speed to match but I may swap to a Boxster tranny. It's a direct bolt on AND the shifting system is off the shelf bolt on. The Boxster CV flange is 100mm so only the axle length will have to be changed on mine.

The boxster 5speed is the audi 012 front wheel drive trans.

That' a bunch of hardware needing direct access to get to in a 914. Are you modifying and expanding the bump behind the 914 seats?

1.8t swap is a homerun! IMO, it is THE swap for this car. Good luck - hope it comes together quickly. It's gonna be FAST...

It's almost the same. Different axle flanges, different shift linkage, different differential.

I already have a hole in the hump from the old track days. The engine should fit without firewall mods. May have to trim the trunk lip a little. Got to get it in there first. Al at Parts Heaven asked me to bring it to their swap meet this weekend. So I will start major work soon. I will be selling a rebuilt 901 with an H gear, setup with a cable shift. PM me with an offer if you want it.

The timing belt and water pump will be changed before the swap. Should be good for 60k miles. I am fabricating a cradle to house the engine and tranny. 4 bolts, CV's, hoses and shifter and the engine combo will drop out. No more difficult than pulling a T4 motor. Just a little messy with all the coolant.
