Inlet manifold is about £220 from Aldon, iirc, DCOE pattern.
Bike carb manifold you will have to get custom made, or try on the RS2K website. I just sold my one
Bodies themselves, well, you could convert some weber sidedrought carbs into throttle bodies, I have. You can get some old knackered ones quite cheap!
Or you can buy some jenveys.
Then there is the question of management.
Throttle bodies do not tend to sit well with MAP sensers, something to do with the inlet pulse's upsetting the MAP, and thus the ecu not getting a 'clean' signal
Some people have suggested you can run a vacuum pipe from all 4 inlet runners through a small fuel filter to smooth out the pulse's, but I do not think any have actually tried.
If this works, then you could very well use the standard ecu to get you up and running.
But ultimately you would really need an aftermarket mappable ecu. You would then use throttle angle to gauge air flow/mass etc, and get the perfect map for your engine.
For the road, imho, it's not worth it, sorry.
You nay see between 10-15 bhp increase with no other work. It really requires head work and cams to get the most from this set up.
