I have sold an R8 V10 for a track car an chose the Cayman R. Lots of work getting a heigo roll bar (rear), GT2 seats, RSS LCA'S, toe links, trofeos etc. but now I want more power. I love the feel and the balance of his car bit really is a special little beat, but moreover would be great.
What costs and gains are w looking at with a 3.8 conversion vs maximizing the stock engine?
I'm hearing 25-35k for a build. I have also heard a 4.0 Metzger is possible (new tranny too?). Of ourselves there is always the Flatsix 4.2 build.
Anyone actually do one of these? Pros vs cons?
The numbers are one thing, but reliability matters. Especially if you track the car.

Forget about GT3 motors as they are too expensive to buy and replace.

Anecdotal evidence says Flat6 is taking a 3.6 DFI OEM crank and combining with LN Eng. 104mm pistons along with their nikasil sleeves. This gives you 4.15L. A 3.6 DFI crank in a 3.8 gives you a 4.0L (LN Eng. can get you the pistons for this). Anecdotal evidence says the Flat6 conversion is close to $30k. Flat6 doesn't want to talk cause they are afraid everyone will take their secrets.
I found and purchased a GTS 3.8. This path was recommended by John at BGB. John is a straight shooter. He recommended it for the cylinder heads.
I can strip this engine and prep it for install myself. Its not rocket science. I am toying with the idea of putting in a 3.6 crank and pistons for a 4.0. Who is familiar with the internals of a DFI motor? The crank is about $3500 new. All speed shops will have to be proficient with the 9A1 because this is the future of flat 6 engines.

Looks to me like a Cayman R. Unless it's been tweaked a bit.
As far as Mezger engines in 987: yeah, it's been done before.. and recently. Expensive though. "Bullet-proof" but expensive. And they can blow... ask me how I know. Then again, it's a metallic mechanical moving part - what doesn't fail after enough stresses have been applied?
I like Steve's idea of 991 GT3 engine in 987s!!

Before I bought my Cayman R, I came within $1000 of buying a 2007 GT3RS but couldn't close the deal. The R intrigued me, and the cost of ownership is much less. I much prefer the mid engine platform, and I got a great deal on ordering the R from my dealer. Porsche refuses to unleash the platform, and I bristle when told "no". I will build the car Porsche refuses to. This is a great platform. I have owned a lot of cars, and I love this one. Just needs more HP. I may fail, but it won't stop me from trying.

I did a lot of research on the 9A1 engine before I bought. I went to a Cayman Interseries race and talked to the owners and mechanics. This is a good engine. I read in the GT3 forums of people crying and nashing teeth. It seems if its not expensive, it can't be any good. BS. BGB and others like them are my inspiration.

My RS is dandy and all that but now I have 40k miles and no warranty, therefore I do not wish to replace the engine nor have accidental body damage at the track.

However more HP is always tempting.

i prefer 3.8 transplant.
we do manufacturing, many different types from light clothing to heavy machinery.....
one off's stuff are ALWAYS fk'd up. there is NO exceptions.
mass produced is the way to go.
3.8 blows up buy another one.
4.15 blows up, how long is the wait to get another?
some ppl have very short fuse and zero patience. 24 hours is about all i got.

a custom engine.... i welcome you to share reliability once you get one. i had many of those things by some very famous shops/tuners. kaboom then cha ching... are sounds i know well.
3.8 voila ... no brainer if you got a good builder....
if my friends would all quite RS, i would be able to get a cay with 3.8.
