So my step dad bought a 911 and rebuilt the engine and it runs alright, but now he's lookin into doing an engine swap. He's looking at a 3.2 but I'm working on convincing him either a Turbo rotary or 3.0 h-6 Subbie, or WRX/STI would be more of a hot ticket and easier/cheaper to work on. Also he's considering switching it to carbs possibly as the car idles fast and he's replaced all the gaskets and sensors he could think of. Input? anyone have swap info or references?
I've vote to keep it all-Porsche, but I'm more of a purist. I think it would have more resale that way, too. If he wants something a bit different, how about a 3.2 with Webers?
The hot setup there would be the 3.6/G50 combo out of a 964/993. Big power, gobs of reliability and still all Stuttgart when he gets bored and wants a new toy.

If that's within the budget, it's the way to go. I like Porscharu's, but I'd really only advocate it if you're saving a car from a worse fate.
For a 2.7 car, any 3.0, 3.2 or 3.6 is a great upgrade.

This concerns me. Why not simply make what is there work? Going to toilet bowls because you can't figure out fuel injection indicates that problem solving is not a strong point - and you can't do any sort of engine swap without problem solving skills.
Personally, I'm not a purist. I'd rather build a car for me instead of building a car for the next owner.
You can't beat an LS motor swap in a 911 - go for the gusto!
Am I the only one who saw the thread title and pictured a Honda Hybrid with a flat 6?
Problem solving isn't the issue, he's just wanting a more modern powerplant. When he got it the engine was locked up from a stuck injector washing the cylinder down. It cracked the liner. Hes had to buy a new case, rebuild set, all bearings, ect. Its not a daily driver, but keep in mind he's 72 years old and does all the work himself.
I'd still go for a Porsche engine as that's an accepted swap and it won't derail the car's value too much, if at all.
964 engine with ITBs is a nice sounding setup and will also yield a nice increase in power.

That is the engine that I would like to have for an Outlaw 356.
Forget Porsche engines...go for the easy power of an STi.
Contact Renegade Hybrids and see what they can do for you!
TWM throttle bodies for that Weber sound, MegaSquirt for the fuel injection reliability.
Larger motor for the power bump.
I've driven one of these with Webers. It's what a Porsche should be.
That said, the cost of a carb setup is huge, and the dialing in of them is not a task for the casual tinkerer. Fixing the FI would be far less frustrating I'm sure.
I'd never settle for a 911 that didn't have the boxer six engine sound. However, a Subaru H6 engine will give you that, plus good power coupled with ultra reliability and low repair costs. Installation, however, is not a bolt-in. Search on the Pelican Parts forums for the thread by the guy who did one. You'll want one, but it's a job for a fabricator.
Go to Andial. They have a 2.9 and 3.0L conversion kit for the 2.7L engine. They offer two versions, one for CIS and another for carbureted or mechanically injected engines.
All you will need for a conversion and will not effect the value as much as an engine swap from an WRX would to a potential new buyer if you decide to sell down the road.
