Anyone ever look into using the 718 2.0 or 2.5? Any clue if the 997 transmission will attach without modification? Assuming you would need to use a standalone ECM such as a Motec, etc? The engines are relatively plentiful, especially the 2.0. What say the brain trust?

interesting proposal, I guess weight would be the biggest savings, while keeping HP close. never heard of a 911 going to a cayman setup, I think you would have to re-think how it mounts, where the turbos fit, as well as the transmission might have to swap to a cayman/boxster, never heard of a plug and play to a 911.

the 911 transmission would have to be used. The cayman setup has the engine sitting forward of the transmission in the cayman. Really no different than using a Honda K engine or ls. With running the boxer 4, it would at least keep the lower center of gravity

Who wants a buzzy 4 cylinder engine in their high-end sports car....not me.

The thought of swapping a characterful NA flat-6 (either 997.1 or 997.2) with one of the most mundane Porsche engines in recent memory is unfathomable to me. The cost would be great and it would result in a worse car, imo. OP must be trolling.

To me, if you have a 997 roller and have trouble sourcing/funding a flat six, the 2.0 sounds like an interesting idea.
Sort of a modern day 912.

scottrx7tt1

no, not trolling? with the cost of rebuilding the flat 6, people are obviously looking to do engine swaps. to date, GM LS, audi 2.7 turbo, even Honda K swaps. why not stick with the brand and put in an engine that is still Porsche made? The 2.0 with a tune is putting out over 350hp, and the 2.5 is over 400hp. I own a 718 also, and it is the better performer out of the 2 cars. The turbo 4 is peppy. Obviously, you would not want to pull a great running 3.6-3.8, but it would be an awesome option for some. Im seeing the 2.0 flat 4 on ebay for $5-6k.

scottrx7tt1

yeah, and with more power than the 3.6 or 3.8 engines.

The one thing I did not like about my Cayman GTS was the flat 4. It was quick and performed well and would still have it if it was a flat 6.

Hartech rebuild or Audi2.7L when and if the time comes.

The cost of an engine for a swap is one thing, the cost of installing it in a rear engined car designed for a flat-6 and making it work correctly, is another. I can't imagine, all-in, it would be much less than rebuilding the F6 or finding a working F6. And if you swap a non-oem engine into a 997, you better plan to keep it forever because your resale value will be zero.

And the thought of swapping in one of the most unreliable engines I've ever experienced, the Audi 2.7TT, is a LOL riot. I had a B5 S4 back in the day and it was, by far, the most unreliable car I've ever owned.

Some swapped 996’s have done well on enthusiast auction sites.

I see so many people spending $30k on an engine rebuild all in. there is no way they will ever be able to get their $ back on that investment. If you have a situation where you have a toasted engine, the cost of a swap is much less than an engine rebuild. I am going to bet that no Porsche purist is going to be interested in anything but the stock form(which is ok), but there are plenty of gearheads out there like me that would find a swap of any kind to be quite cool, and could see the value in it. If it were to ever happen to me, i would do a swap in a heartbeat before i spend $30k+ to have a rebuild done. I bet the guy that has the k20 swapped 997, and the Chavis Performance guy that does the LS swaps wont have any problem selling the 997 swapped cars for close to retail.

That is because you didn't speak nicely to it, pat the dash and say good job.

But yes the joke with the B5 S4 was that half the time the engine was out of the car.

In all seriousness the blocks are pretty robust. Its the **** turbos and solenoids that plagued those cars. With the kit you eliminate the majority of that crap and go to a single turbo that can be swapped out in 45 min.

My S4 was a 4.2L but I did have my fair shares of 1.8T builds. One was a big turbo Avant that took hours to diagnose a misfire issue, which was a $.05 injector clip.

Interesting that these were all 996s. I'd venture to say that the engine swap in these might have actually raised the value as 996s were selling in the high teens and low 20s just a few years ago but have risen as the other 911 models have too. I'd be interested to see what a desirable bodied 997 with a swap sells for vs a regular one as I bet those are lower by comparison vs the 996s here which are higher by comparison.

So, folks can buy an engine, make it fit the 997 engine bay, work out all of the electronics communication between the Porsche ecu and the Chevy or Honda engine for much less than $30k? In 2023 when a McDonalds value meal costs $15? Maybe if they do ALL the labor themselves. If I were faced with a roller 997, I think spending the $30k for a rebuild or upgrade of the stock motor would be the best decision, not just for resale but for preserving what the 997 is.

A big single turbo car is the antithesis of a driver's car if you ask me. It's a drag car, like a 90's Supra. Kiss throttle response goodbye. And nothing ruins a driving experience like turbo lag. Nothing, nothing, nothing, then EVERYTHING. I'll take NA instantaneous throttle response, thank you.
