does any one no which throttle bodies from a motorbike work best on a zetec engine 2.0l. or any ideas on which would be good??? also what kind of ecu would i need eg megasqiurt.

[XRMike]

Suzuki GSXR ones seem to be the best, but others can be used, its a custom jobbies either way, you need someone who can weld/fabricate,and with bit of technical knowledge to get it all running.
As regards to an ecu, Megasquirt seems to be the way forward,cheap and cheerfull, a few people have gone down that route with good results

Im selling some R6 ones on ebay,with a ST170 inlet (type R6 Throttle, in serch on there, you'll see them)

depends how you approach it really, if your gona use an st170 inlet to mount them onto, the itb are best such as pre 2k gsxr one, as they separate into idividual units. after 2k they come in pairs i think.
Pairs still mite fit the st inlet not sure. r6 one you can separate i think, im sure theres some kawasaki ones you can too.

Or you can use them in pairs and get a custom manifold fab'd up. Really quite easy to build up the bike tb's. Only issues you may have are fuel rails and injectors, cuz if you space them the fuel rail wont fit, and the injectors flow pretty much the same as standard zetec ones i think, so you might want higher flow ones.

Im running gsxr 1000 ones on a st170 inelt fuel rail and injectors on mine.

Also using Megasquirt. Cant fault it tbh, awesome peice of kit, just a few things to get to grips with on it, but pretty easy to pick up, not masterd mapping it yet tho lol, leave that for the pros, but many people map it themselves with great success.
Some people run 1000bhp monsters on Megasquirt, so deffo not sumut to push aside, for the way of omex or the like
