Right in the middle of an M57 engine conversion in my Sunseeker Tomahawk (previously driven by 2 x petrol 8.2L V8 502 Mags).
I have adapted 2 x manual 330d engines to mate with existing Bravo 1 drives using custom adaptor plates. One plate for rear of engine to locate starter and act as rear engine mount location. Another plate to adapt clutch pins & bolts to what was the BMW propshaft doughnut (now used as drive shaft shock adaptor). Propshaft doughnut drives in to custom adaptor driving Bravo input shaft.
Jabsco raw water pump driven by custom adaptor made to fit on where fan viscous coupling used to screw on.
Raw to fresh heat exchangers Bowman GH300's (ebay specials!) Charge coolers also Bowman (yet to obtain).
Exhaust (yet to be fabricated) will be dual skinned, raw water cooled stainless with mixing point just downstream of swan neck.
Electronics and software is my profession so old gauges have been replaced by touch screen PC running my custom software pulling engine data from ECUs over CANbus'.
My only remaining question is whether or not to use 2 of the 4 through hull exhaust outlets or whether to plumb in to the Bravo leg exhaust ports which exit through the centre of the prop but are currently blanked off with cover plates?
I have a CNC mill so making the adaptor couplings is straight forward enough if I go the through prop route.
If anyone needs adaptor plates made or copies of my software, let me know and I'm sure we can sort something out!
