Anyone tried that?

 

Cheaper to buy a new GT3. I believe Btim has something cooking though.

 

Yes, they call it a TPC and it beats up on the GT-3

 

This should give you some more info:

Couldn't find info on their site. Any links?

 

I think this is the thread you meant https://www.6speedonline.com/forums/...vs-997gt3.html

...and this is the "key post"

 

I was thinking about a cayman with a stroked 4.0 gt3 motor with around 500 hp or 4,0 turbo motor around 600 hp, sequential transmission, all the necessary suspension stuff and around 2200 lbs exclusively for track. anybody did anything like that before? sounds good to me, but?

 

It was done by Jurgen Alzen Motorsports and competed in GT4 class in Europe several years back. We're also currently affiliated with a similar project that is well on it's way. In fact, the engine and gearbox were test fit just last week. But I'm not in a position to reveal any more details or pictures until the owner of the vehicle decides he wants it made public.

Though what is public and easy to find is the BGB 3.8l 997 Carrera S DFI swaps that have recently been done in their two retired Grand Am Caymans. Look around this forum a bit and youtube and you'll find these monster cars. For something cost effective and pretty damn close to "bolt in" an X51 DFI 997 engine is hard to argue with.

The first car mentioned will be upwards of $200-250k when it's all said and done. The BGB cars are being done for half that. Either way, such a project is not for someone who has any concerns about resale value or isn't willing to open their checkbook wide open. The BGB cars were so expensive because they were done on Grand Am racecars that already had 6 figures into them. But for someone with a 2009 DFI Cayman S, a 3.8l 997 swap could actually be done without taking out a second mortgage or robbing your kid's college fund.

 

FVD did a 3.8 carrera dfi engine to a cayman for 25k euros including the engine. I can not see how that would cost $200 - $250k. With all due respect, that sounds ridicilous to me.

Anyway, I have a spare 997 Turbo engine I may be willing to reinforce with a 4 liter stroker with a pair of GT series turbos and put in a Cayman. Any ideas? I don't like the DFI engines, because they are garbage to me next to a GT1 block.

 

GT 3 engine is entirely different from the 3.8 dfi, $50K difference. Then you have to make it work in a 987, as others have stated, the bell housing won't match with the GT 3, but mates right up with the 3.8. Do more searches on Planet-9.com.

 

Right along the lines of what I was about to say. As I alluded to in my post above there's more than one way to skin a cat. I can take a 2006 Cayman S and throw in a 2006 997 Carrera engine and have a $50-60K hot rod including the cost of the car.

But when I'm talking the numbers I mention above we're talking a new 997 Cup Car crate engine with Motec and crate sequential gearbox. You're in for $125-150k right there. And you haven't even started the fabrication to make it fit, or any brake or suspension work, or a cage, or any sort of body work. Building a Cayman into a racecar that can run toe to toe with a 997 Cup Car for $200-250k is pretty easy to do. And by easy I mean it's easy to spend that much money, not that actually building the car is easy. Building it is not. Writing the check is the easy part...

 

Then there's that little detail of learning how to actually be able to use that much power without killing yourself or others.

 

Holy cow...it's nice to actually see some hard numbers about this dream swap. I daydream about this type of swap all day, and stuff like this serves as an appropriate reality check for sure.
