Boring 2.7 to 3.0l low compression with TI rods build?

So Iím either going to turbo my 08 S or 07 base. Question is has anyone bored a 2.7 to 3.0 and gone Low Compression for maximum boost? Have a very skilled engine builder I will be working with and would prefer to build the 2.7 since it has 100,000 more miles than the S and at this point is as close to worthless as a Cayman can get. So I think a boosted track car may be in order. Just want to know your thoughts. Thinking either that or boost the 2.7 till it blows then drop a 3.4 into it. Iím ordering the kit the second I decide so this is by no means a pipe dream!

I used to have a Kawasaki GPz turbo, so I've had some thoughts about this. Turbo charging will put a lot of stress on the old engine, valves, etc, rods, rod bushing and bearings, crank and crank bearings need to be pretty much top notch. My bike engine was purpose built by Kaw--a much heavier duty and quality build than the standard 750.

You'll need to rebuild whatever engine you choose. Using the old 2.7 you'll have probably as much in the rebuild as you would with a low mile 3.4. You are going to lower the CR, no matter what or you won't be able to maximize the boost and still use premium pump gas.

Does anyone know the max power the factory crank or factory block can hold? Donít want to build it to find out the crank or block splits at 500

Also anyone know what plug the turbo cayman owners run? I see both copper and iridium but from what I know about turbo cars is you want a colder stage than stock plugs. Thanks!
