Well with regards to the engine fitting in the frame...my guess would be yes. As far as I'm aware the only frame that may be differrent is for the 748R...which has a larger airbox than any other 748/9** variants....so don't know if this means it has a slightly different shaped frame or not???
But you would need to think about why you are doing it. Unless you were a Skidlids or somebody who has a lot of contacts in the bike world and access to the bits needed...as well as the required *mechanical knowledge, premises, patience, funds (*delete as appropriate!) to sort something like that, you could in the long run find yourself with an expensive project, that lets face it, will then have naff all residual value.
I think dibs is right in that the way to go would be to find a bargain 996 etc and transplant the bling over to it from your great 748
As you know, I picked up probably bargain of the century with my 916SP...but with 130 BHP at the rear wheel...all the bling you'll ever need...for £5K...it has to be a better option than building your own special?
Now as for an 853 kit...well thats another discussion entirely
