I've currently the same kind of project by upgrading my Bipo.
But I'm using another engine in order to keep a 916 in the garage.
Mods are:
- 955 by reboring cylinders kit
- lightened crankshaft SP3
- Ti conrods
- Hi comp pistons
- 748R injection (TB, airbox,...) so frame but also heads... modifications
- lightened parts (clutch carter,...)
Worst part will be injection set-up. But I think I'll use PCIII...
