Hey Ephatch, I need help knowing which throttle body to get/use. I have a K24A1/K20A2 with RBC manifold. Which throttle would be best to use? The motor has been built to make over 500hp. Also, to fit the TB up, all that is needed is the karcept adapter? Thanks for the help.

There is only one TB that is reliable, and that is the OEM TB. I have had very negative results from the aftermarket TB's that are presently available. Hybrid racing has a new TB in the works that has both of the presently used bolt patterns that Honda uses for Kseries TB's.

So which OEM TB are useable besides the EP and DC5's TB. Can a CRV's TB be used?

take your throttle body and send it to maxbore.

Now if only I can convince Talon to sell me a TB cable bracket...:mangel:

so is the EP3 TB good enough to handle the power? or is one from a TSX or something else better? thanks

The TSX TB will not work, simply have the stockie bored out by maxbore.

I still need a adapter like karcept though right?

Yup, unless you get a RBC that has had the bolt pattern changed.

Bump for an answer on this, Accord/Element or CRV can this be used in an EP? Thank you.

You may be able to get something else to work, but it isnt worth the effort as all the other Kseries TB's are smaller.

Do you happen to know the sizes? Would be some good info.

if you have a spare PRB or RBC manifold send it too.
He'll portmatch the intake side and do the exit ports to match the hondata gasket for like an extra $125.

When he ships it back to your address it'll come like diz:

What type of gains can be expected (Numbers/ Response)? Also could you post pictures if you have it apart of the ports by the Hondata gasket? Who painted your RBC? Why do you say extra intake manifold?
