water cooled porsche engine in air cooled chassis?
I had a thought. Why not swap a modern flat 6 porsche engine into the 993? The form factor would be right. Companies have swapped small block chevys in air cooled porsches for a while now, so, the issues of routing water cooling seem to be solved.
Why not? A 997 engine is a lot less expensive than a 993 engine, gets better gas milage, and has more power.

It would take some real creativity with a 993. There's alot more electronics and other stuff taking up
just about every cubic inch of usable space than there was is in the earlier 911's. Changing out the computers and getting everything to work would be another nightmare.
I always found those Chevy conversions to be a form of automotive blasphemy, myself. At least this conversion (for those brave enough to attempt it) would remain 'in the family'.

It might be interesting to attempt this with an engine from a 997 based GT3 or a Turbo, but I wouldn't even consider going standard Carerra (wet sump) route, just for a few extra horses. I would rather put the money into 9Meister heads and the 4.0 liter kit !

Its been done for race cars,...
FWIW, the 996/997 engine will not mate up to the 993 transmission as their mating surface bolt patterns are totally different. One can however, install the GT-3 engine as thats a derivative of the air-cooled engine you currently have.
Another issue is that the 996//997 engine is not as durable or reliable as the 993 motor with the exception of the Twin-Turbo, GT-2 & GT-3 powerplants.
Its all doable with a realistic budget and the net result is a very fast car indeed,...

The 993 motor is not as easy to service as the 996+ motors, but at least they don't blow up without any reason.
The good news is a crate motor is cheap as hell.
The bad news is that the new 996+ motor does rev much smoother, and produces more power than the good old faithful.

The thing is, if I blow up a 993 engine, it costs $25k to replace. If I blow up a 996/7 engine, it costs $8k to replace. All it takes is one blow up to justify the cost of the swap.
A 2.5 subaru STi engine will make 500 reliable HP for a lot less, but, I didn't want the purists to lynch me for the suggestion.
