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.
Exactly. When 996s were $15-$20k cars, what do you have to lose swapping in whatever you could find. In that instance, a $30k engine rebuild is more than the value of the car.

997s were never that cheap and are still much more desirable than 996s. $30k still stings, but is more palatable in a $60/70/80k car.

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.
Yep, there's a reason my only turbo car is my Cayenne TTS land yacht, which is pretty much a highway locomotive and the sports cars that are forced induction (1 of the 997s and 1 of the 928s) are supercharged instead.

It's specifically the aftermarket single turbo setup I just really dislike in a sports car. All I have experienced are just so peaky with nothing going on down low. It's like the entire driving experience is completely sacrificed for 100+ mph highways pulls.

Seems like an abomination sticking anything other than the 3.6L or 3.8L 997 engine in our cars.

Another Thread proving the importance of the investment in a Bore Scope Inspection prior to any 997 purchase.

Also buying higher mileage (90K-110K miles) 997 w/clean cylinder walls looks to be the smarter purchase for those concerned with Bore Scoring.

After scoping 2 997S cars last year with terrible scoring, I was grateful to find my 06 3.6L C4 with clean cylinder walls at 106K miles.
Very comforting/peace of mind not having to deal with the Bore Score issue.

the new technology turbos have almost no lag. I have a friend that has an 850hp Supra and has some new precision brand turbo that is super responsive right off the line. Something inside of me loves turbo lag for some reason. I had a 79 911 widebody conversion that I converted to turbo. I used a K27-7200 and it didn’t light until about 3800 RPMs, it was like turning on a light switch. I just love that burst of power. Same goes for an FD Rx7 that I built years ago using a greddy T78 turbo kit. It was the same way.

I’m a DIY kind of person. If I did a swap, I’d do it myself and I guarantee whatever power plant I decided to use would be well under $30k. You can get an LS3 crate engine straight from GM for under $10k. If you decided to go the 2.7 Audi route, you could stuff an under 100k mile engine with a bunch of mods for under $3-4k. Engine mounts and transmission mounts are pretty simple. You may need to custom make a transmission to engine adapter and figure out the wiring. The lambo guys are using motec standalone ECMs and able to mate it to the existing electronics. The Porsche wiring isn’t any different

I'm totally fine with an LS swap. I know it's not a flat 6, but I'm fine with it if it saves the car from a sad death in a wrecking yard.

Besides, at the rate we are at, if the electrification "progress" continues, we all have limited days left driving these glorious sounding cars. Instead, we will be driving vehicles that are more appliances or a smartphone than a car, and in the process losing vehicles that have a semblance of a soul.....

/End rant

Just for the record, the 718 flat 4 is an excellent motor to live with on a daily basis. People hate on it but I have one in the family that my cousin daily drives. He could easily jump to another car NBD but he loves the 914ishness of the 718 boxster. I would actually love to see this swap. With a pretty gentle tune, these motors can RIP too. I am also all in for the Audi 2.7 swaps. Those are so cool. K swaps seem weird because the motor would sit so high and it is really shoehorned in. LS are fine too but I like the family connection of the audi in a sorted strong motor with a TON of aftermarket, or the 912esque nature of a 718 swap that could look absolutely factory and be FAST with very little mods. Just IMO (flame suit engaged).

It’s just a car. I prefer natural but gaze and admire silicon enhanced as well.
