I realize earlier 930's came with the 3LDZ, and I'm not sure how they are different from the later K27 7006 and 7200's, however I was under the impression that all of them were still K27 frame turbos? Are you maybe just referring to slight differences in fitment such as a bit of custom work on the intake side? If so, that's really not that big of a deal. It's usually a lot easier to fab up some custom intake piping and/or couplers as opposed to trying to re-work the exhaust side (new muffler section, modifying or replacing header turbo flange, etc). Take what I say with a grain of salt as technically I own a "wannabe" 930 and not even the real thing.
The 3LDZ and K-27 have different physical dimensions. While the T-3 flange is the same on both turbochargers, the console support mount will have to be reworked to support anything other than a 3LDZ. The up-tube or downtube to the IC must be modded because the offset of the cold side outlet is different than the 3LDZ. I believe the cold side inlet connector tube is slightly larger on the K27 as well.

Using any turbocharger other than the stock 3LDZ, will require some modifications. There are no free lunches, to paraphrase.

A thumbs up to K27S!
Looking forward to mine arriving any time now.
I'll have a used Kokeln for sale if anyone's interested.
NOT going to sell my awesome Kokeln intercooler though, which IMHO should be a high priority for all turbo powerplants.

I agree with Rarlyl8.
I had just posted a long diatribe on just what was not "bolt on" with the K27S turbo that I just installed. Bolt on to me should mean bolt on.
It is a shame the installers/tuners don't tell you the details about what is really invovled with the install.
I don't have a link here, but do a search under my user name and get a feel for what you're in for. Username is "Fredmeister"
I had hoped that one of the installers would post a picture log of all that is really involved and the mods to all the components that are required for this to work. Should be a nice way to inform everyone as pictures tell a great story.
I may try to start one myself once I have more time.

Fred

Spoke with Stephen today, super nice guy. I ordered the K27S and his intercooler with pressure pipe adapter. Should have it sometime next week.

He said everything should bolt right up, only issue I might run into is the Turbo bracket. I'll find out I guess once I do the install.

All that using a K27 7200 was done on mine before I bought it.
Looking at the turbo support bracket it appears it was cut, a section was cut out and then it was welded back together so it would fit the K27 housing.

I'm sure you'll be happy with the final results.

Let us all know if this is the only mod you need to make, being the turbo support bracket.
I bet you find the intercooler will be raised and the inlet pipe to the turbo intake will be off center downward. Overall the turbo centerline will sit higher in the car.
What headers are you bolting it up to?
Take some pix of the install and post them.

Thanks
