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.

24 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1Original post

Can i put a Gt3 engine in my Cayman S?What i have to do with the gearbox??

POST 2Original post

Possibly, the factory has done it for a test mule, but no aftermarket tuner has done it other than the Alzen racing team that I know of.

POST 3Original post

I had inquired about this at a Porsche tuning shop and was told that the mounting points are different and that our transmissions wont handle the addl. HP. You could rig a new fram for mounting, but would it be as effective...I was also told good luck in getting a GT3 crate engine this decade.

POST 4Original post

the gt3/turbo engine have a diff bolt pattern for the bellhousing. they use the older G50 trans. they will not bolt up to the caymen trans.

POST 5Original post

A 3.8L with X51 would give you 380 and be cheaper than a GT3 motor.

POST 6Original post

New GT2 Engine Recent AutoWeek indicates that the next GT2 will produce somewhere between 525 and 550 HP! And will be the first production 911 to break 200 mph. I believe it is Direct Injection. Now, to fit one of those puppies in a Cayman! :banana: http://www.planet-9.com/general-off-topic/13595-gt2-brochure.html

POST 7Original post

i spoke with ruf. here was the reply i got.... (i paraphrased it a bit) "not recommended b/c it's very difficult, ecu, mounting pt, gear box, cooling blah blah... but given enough $, yes, it can be done..."

POST 8Original post

9ff do a 4.1L swap, giving about 420hp, its on their website you can look it up.

POST 9Original post

Bigger cojones for my Cayman S I am very intersted in adding a significant amount of HP to my Cayman S. I'm talking bringing it to a total of 380 hp or more. Who does the best/most reliable job and what is the added performance and cost estimate? Who is 9ff?

POST 10Original post

They are one of the premier tuners for Porsche. You can do a search here as well as the web. 9ff mods are very nice and very expensive. 9ff Fahrzeugtechnik

POST 11Original post

It's considerably more than just direct injection - it is basically a juiced-up version of the motor in the 997 twin turbo... different turbos, timing, ECU, exhaust system and boost figures. The GT3s, TTs and the new GT2 use the same basic motor, which is the old style v-bottomed motor with real dry sump and water-cooled heads. The GT3s are normally aspirated. The GT2 motor would be quite a feat to get into the Cayman, for all the reasons stated above, plus you'd need a lot more room for all the plumbing that comes along with it. brad

POST 12Original post

I would encourage you to talk with a member here named Arcticsilver before you decide on any 9ff items.

POST 13Original post

stever13, if you are serious about a big power upgrade I think having a conversation with RUF would be a good starting point. They offer both the engine transplant (3.8) as well as the supercharging option so they could probably give you a good cost/benefit analysis on both options. Also, RUF offers warranties on their work. RUF Automobile Cayman S Conversion

POST 14Original post

Stever13 and OP; it seems like the 3.8 transplant is the way to go for more power. Stever, there are a few tuners in North America that do the swaps (where are you located?) Personally, I would do the transplant over the RUF blower. Centrifugal blowers, like the one RUF uses, dont give that real jolt of power you would want for spending so much $$. You are looking at about $30K US to perform the swap.

POST 15Original post

Farnbacher/Loles would also be a good choice. Their GTR Cayman is 400+ hp Here is a link to all the info for the GTR http://www.farnbacherloles.com/general/pdf/GTRflyer.pdf

POST 16Original post

Bigger cojones thanks for the info everyone. I'm in san francisco. With those kind of price tags $30k+, I'll have to gather some info particularly in reliability. Thanks again!

POST 17Original post

If reliability is your priority, then the X-51 transplant would probably serve your purposes the best... if done right, with a brand-new crate motor from Porsche, you'll be able to have it serviced at any Porsche dealer. If I remember correctly, the crate motors from PAG come with a two-year warranty. if you use a shop for the transplant that will give you a warranty on the actual installation process, and the reprogramming of the ECU, etc. then you should be pretty well set. brad

POST 18Original post

Ditto! I was there when Charles had his car dyno tested and drove the car. It was a horrible installation and didn't come close to what they had promised. I couldn't believe the mess they had made of his car.

POST 19Original post

I've got to agree that the bulk of evidence doesn't exactly aid them in their case! I've got to admit that from what I've read about some of these companies, not just 9ff, there is a lot of alpha testing going on at the expense of the consumer. Oh well, the alternative is to buy an old 'Stang with a 5.0 and proven aftermarket parts! And did they ever need them!

POST 20Original post

all I can say is that I have had nothing but good experiences with Farnbacher. They have backed up their products and have true race and track experience for those of us that take our performance mods to the track. You don't win races with knowing what you are doing.

POST 21Original post

I agree. F Loles was a pleasure to work with.

POST 22Original post

Or, we could all wait maybe 3 years and see what Porsche might have in store for the little Cayman S and base Cayman. I know most folks do not expect much to happen with Porsche's Cayman for a long while, but you never know. The success of the racing Caymans produced by independents might just "force Porsche's hand"! And a well balanced Porsche version of the Cayman with a modest increase in power (say, 330 hp) would probably be at least just as fast as a tuner version with lots more power and certainly less worrisome, because it would come with a 4 year warranty. Wait, and yee shall see! We are all (and I include myself because I have considered a 3.8L swap) acting like a bunch of spoiled kids with no patience.

POST 23Original post

A little bird tells me to watch for a test of the RUF 3400 K authored by the same fellow that evaluated the X-51 RUF Boxster in an upcoming issue of "Excellence". Possibly the issue after next.

POST 24Original post

economics of engine swap These "engine swap" threads are amusing. Do people honestly think they can get their hands on a high end super car engine for an engine swap into a cheaper car???!! Yes....the supercar engine is likely worth more than the Cayman. I would not be surprised if resellers requested >$70K for a modern GT2, GT3 or turbo engine that will actually run! A wrecked modern supercar would not be available to just any "Joe/Jane Smith". A person must be willing to pay $$$. A race team could outbid Joe/Jane Smith. The low availability and high demand equals high price (and likely high risk if used). Want a GT3????.....Get in line to buy a GT3. Best bet IMHO.
