He also said to get the optional 6-spd as well, which was when I checked a little over $2600.

Suggestion
Neil please help me on this one: I am aware you can still get the 3.4 liter S/C now and if later you want to do the engine swap to 3.8 you still keep the same S/C and for pennies just change the injectors and voila...correct?

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Greetings fellow croc drivers:
I'm in the market for more horses.
One option is upgrade via a 3.8L conversion. Another is to install a supercharger kit. Numbers wise, the end result in HP and torque gain is similar for both approaches but
I am more curious in learning about what difference, if any, the driver will actually feel behind the wheel.
Would appreciate any views on the pros and cons of each approach.
Cheers and safe driving during the holiday season.
I thought the supercharger was around 400-410hp while the 3.8L is either 355 in standard form or 381 in X51 form? I've driven the X51, haven't driven the SC yet!
Don't SC tend to affect the reliability of the car? Of course, I guess the jury is still out on the 3.8L conversion, but it's a normal motor that should have no problems.
Do you plan to track the car? If so, I think (others please confirm) that the 3.8L would make more sense.
If you are going to track the car a lot I would recomend the 3.8.I have done a 3.8 conversion for a fellow board member who tracks his car alot and has had Zero issues.

For longevity I would pick 3.8 over Supercharger. Unless some sort of supercharger was from factory and later was upgraded, I keep on hearing about boys killing their engines. Mostly because of lean conditions that pop up out of nowhere. 3.8 should be rock solid.
A couple of quick questions Neil, and they might be pretty dumb, so please bear with me. Do you keep the original engine? I would assume so, but you never know. Also, what prevents this swap in a non-S?
Neil told me a 2.7 would work if going for the engine swap. He also said to get the optional 6-spd as well, which was when I checked a little over $2600. When adding up the numbers, a Cayman 3.8SC under $85-90k would be a hell of a car. From the website, his setup includes extra cooling, a stronger clutch, and more. If the brakes aren't up to snuff, a new kit should be around $2-3k.
The car should be able to handle the hp too. The 997tt has 480 hp and isn't the Cayman supposed to have the better platform?
Neil please help me on this one: I am aware you can still get the 3.4 liter S/C now and if later you want to do the engine swap to 3.8 you still keep the same S/C and for pennies just change the injectors and voila...correct? Thats what I am doing....getting the S/C now and doing the swap in 1 or 2 years.
I personally am waiting a bit to see what Turbocharged options are down the road... 500+ HP is the word I hear from one supplier for 9-10k installed :dance: ... They should have their system ready by the spring... I want to weigh all the options before jumping in to the deep end of the pool!!!
