Holy jesus, that is a monster of a job summed up so fast.
Incredibly impressive work. Wow!

Its possible the automatic version of the 996 transmission that Josh used could be used, but physically fitting it would be a big hurdle as they are even taller and longer than the manual. Plus you need to figure out a standalone computer for it. Any auto transmission after the mid 90s are not going to be "dumb" and will require a functioning computer. Just another big amount of work.

Besides the Porsche 911, there aren't many rear engine cars with Auto transmissions.

The first proper automatic transmission for the 911 was in the '88 964 generation. This was a ZF 4HP22, used they go for about $1000 and should bolt up to the same adapter plate. This is a very common and decent quality transmission used in a lot of German cars in the late 80s and early 90s; very simple transmission compared to a modern automatic. it would not be that difficult to wire up electronically. However it is only a 4-speed and is only good for about 220 newton meters of torque hence the name for 4(speeds)HP22 (power rating.)

That transmission would be under a lot of stress with a stock GM V8. But it's possible somebody can rebuild it to handle more power.

However making it physically fit is still the big challeng As there is a drive shaft on the right side that would really dig into the frame where the passenger side trailing arm bolt is.

..., is this, or a similar type of engine, just as "easily" feasible with an automatic transmission or can you not really mix match motors with different brands of automatic trannies?

One thing I see with these V8 conversions is the axle shafts have a pretty large angle since the mounting must push it further forward. Is this going to cause reliability problems with the CV joints? I would think your goal is to make the engine mount a far back as possible.

Aren't these axles longer than stock too Josh?

They have a spacer to increase their length (to provide adequate plunge) and larger cv joint boots to prevent ripping at the increased angle. Otherwise these are stock axles and CVs
The angle you are observing is approximately 10-12 degrees, Porsche 930 style joints like these can be run up to 26 degrees before you run into major issues.
Furthermore I have tens of thousands of miles on this increased angle setup in multiple cars, without an issue. I will agree they will wear out sooner but nothing in the realm of premature.

Thank you for the comments guys feel free to ask questions

Epic build. Thanks for sharing the photos and detailing the process for the rest of us.

Love this! Certainly a dream build. Very well done, so clean! What a transformation!

awesome engine swap!


a quick question about this piece:

Wilwood clutch master cylinder, a smaller bore than stock to help lighten up the clutch pedal.

is this master cylinder plug and play on the stock location? same thread for the clutch hose and reservoir hose adaptor?
is the pedal feeling lighter?
Thanks!
