Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I've seen a lot of discussion on swapping the Cayman S engine with that of a 911 or 911S, but why hasn't anyone brought up using the new GT3 engine?

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.

I've seen a lot of discussion on swapping the Cayman S engine with that of a 911 or 911S, but why hasn't anyone brought up using the new GT3 engine? It's 3.6L and more powerful than the 911S 3.8L.

POST 2Original post

thats a good question....i know techart has a future engine swap planned but i think it is the 3.8L in the 911S. maybe its because the GT3 hasnt officially become available yet and so there isnt enough information on the actual specs of the engine? I am sure that one of the big aftermarket companies like techart, speedart, Ruf, etc. will have something available soon.....at a cost of course.

POST 3Original post

The 3.6 swap might be easier to do than the 3.8L, but I agree we haven't seen one yet due to limited availability of the GT3 engine. The 305-kW (415-bhp) 3.6-liter flat-twin engine produces a specific output of 84.7 Kilowatts (115.3 bhp) per liter of displacement. This performance places the new-generation GT3 in its displacement class at the pinnacle of road-legal production sports cars with naturally aspirated engines. The six-cylinder engine reaches its nominal output at 7,600 rpm. At 8,400 rpm, the engine speed limit again lies 200 revolutions higher than for the previous model. This makes it a world leader in its engine-size class. In addition to this high engine speed concept, the optimized airflow rate considerably improves performance. This is made possible by the variable intake system with a throttle valve enlarged from 76 to 82 millimeters, the optimized cylinder heads and an exhaust system with low backpressure. There has already been discussion about swapping the GT3 engine into the Cayman here: http://www.planet-9.com/topic.asp?TOPIC_ID=2107&FORUM_ID=10&CAT_ID=3&Topic_Title=GT3+debut&Forum_Title=Off+Topic Edited by - mpollard on 03/22/2006 10:04:01 PM

Unfortunely, the price for the mod alone will be at or more than a base Cayman...
