What is the best throttle body and size for an all motor H22 setup. I have heard so much it's really hard to figure anything out. I have a euro r IM if that makes a difference. I'm leaning towards 68mm but I have no idea who to get it from. Any information would be appreciated. Thanks in advance.

 

There is no "best" throttle body for any N/A setup. A proper throttle body allows the best flow and provides good throttle response. A throttle body that is too small will cause restriction and power loss; a throttle body that is too large will cause poor throttle response near WOT. If you explain your setup, maybe we can better suit a tb for your power needs.

 

Come on dude,we are talking about h series here not b series! 68mm are for them small block b series, get something like 70mm or 72mm for the h series.

 

my 70mm seems to be pretty responsive.
