Roock Porsche 997 Engine 3.6 / 3.8 Ltr Boxster Conversion Kit

Just found something new ( to me ) and interesting on ebay .. seems very interesting if for 2K means I can throw any 997 engine into a 2000 Boxster .. according to Wayne @ PelicanParts .. for my 2001 I'll just need the new 7.8 DME .. but very interesting if they can make it work for 2000 and older cars ..

Has anyone here have experience with this kit or with Roock Autosport ?

If you're serious about doing this send me a message, I would be interested in your current engine.

Thanks for the heads up Sr. Rocket...What is a "vario cam switch" referred to on fleabay?

with this kit you don't need to change the dme; the 'switch' allows you to use your old dme to control the variocam+ on the younger engines. the newer engines change the cam profile as rpms increase (variocam+) but the old dmes don't have the logic to do this. so, roock adds a 'switch' that triggers the variocam+ based on egnine rpm.

todd holyoak, one of the innovators on engine swaps for boxsters, tried this and if you search you can find info on the various mechanisms he used to do this. the end result for him, however, is that you just can't make a switch work as well as a dme specifically designed to correlate this task with a/f mixtures, timing, etc. so, todd instead went the direction of swapping dmes. the issue there is that the 7.2 and 7.8 dmes differ significantly on communications protocols (ie, the 7.2 has dedicated signal wiring, while the 7.8 multiplexes multiple signals on single wires) so swapping the dme also means chaning hvac control unit, dash cluster and abs controller (as well as revising/extending wiring harnesses).

what you probably get from roock is a 993 engine mount, some transmission mount spacers, perhaps some hoses to adapt fuel delivery, aos, etc., and the variocam + switch.
