Has any tried to use yamaha r1 throttle bodies for their turbo set up? The reason for asking is because I'm trying to plan everything that is needed for my turbo conversion.

Regards
Alex

indeed, on what.

The issue with bike TBS is finding injectors that flow enough and that fit. I found some 330cc ones for my Kwack TBs.

Well a 940 head has 2 inlet ports and and R1 4; so not ideal really.

If you want to use multiple TBs, then you need sequential injection (lots of info how to go about it in the injection section of this forum).

If you want to just use batch injection then it's a single TB that you need. You still need to make sure that you batch fire correctly (4 times per cycle) to make it work.

I can see no way of using 4 TBs in any sensible system.
