will a 996 turbo engine fit into a boxster?

Well Ruf have fitted GT3 engines (same block without the blowers) into some of their Boxsters, so maybe....
But you've got a bit of a job on your hands!

Don't think you'll be able to use the gearbox. Not unless you plan to go backwards really fast. [

There was a turbo engined boxster at the last RS day at Oulton Park. Unfortunately I don't know any more details about it. Of course, it was very quick on track but surprisingly not on the same pace as most of the GT3s which just goes to show that a much more powerful engine in a boxster will not necessarily mean that it will be a GT3 eater.
Maybe that was down to the different driver abilities. Would be nice to have seen a back to back comparison by the same driver though/
I think there are a few turbocharged Boxsters around... However that's not the same as fitting a 996 Turbo engine in. The engine is not the same base design.
Would be interesting to know which are which.

Totally agree with you Peter that the driver factor is always difficult to quantify. My observation was that most of the GT3s were quicker but then again, the RS day attracts a lot of good drivers. If I'm not mistaken, the turbo engined boxster (and I was lead to believe that it was a true 996 turbo transplant) is a friend of Simon at Porshapart. I guess it must still be very much a work in process, otherwise the car no doubt would be much better known by now and would surely have appeared in some Porsche mags.
On a related topic, I know the owner of the 9M supercharged boxster very well. That car went through many transformations (including three engines) but was always a disappointment because the reliability was never there, neither was the real world performance.
For me, the boxster is at its best as it left the factory and the latest Spyder is the best of them all [

I believe that is because they try to do it without changing the factory pistons. I don't know for sure but I've heard that somewhere and would make sense if that is true. No reduction in compression ratio would greatly limit the amount of boost the car could run so you'd get pretty small gains. No additional taper on the pistons as you would have on factory turbo pistons means hotter pistons, leading to running tighter tollerances and then seizing.
I would think there are a few problems to overcome. Principally HEAT the Boxster rear end just isn't designed to cope with it. And where would you put the intercooler? Other problems may occur when trying to get all the electrics talking to each other. I think my dim and distant memory remembers something about each unit in the car being coded. So a new Turbo DME might not work without recoding? Then as Mark suggests gearbox matching might prove a pain. Nothing is impossible, but some things may as well be[]

GT3 Engine it is then.
