It really depends on engine displacement, headwork, cams, intake manifold, and rpm's. Honda has researched this subject well and found 62mm TB works for 2.0L & retains excellent throttle response . The 2.4L Honda found 64mm throttle worked best.

Jan 05, 2011 · If I remember correctly it is something to do with the idle control and there needs to be a hole drilled in the inlet manifold where it meets the throttle body, but I'm not 100%. Are you sure it is an RRC and not the RBC? People usually go for the RBC on an EP3 K20a2 engine, but the RRC is reported to get better results.
A '06 TSX 64mm throttle body was bolted on in place of the 60mm stock unit. Since they're both drive-by-wire, it was simple a matter of opening up the RBC intake just a bit. Obviously all this old school hardware is incomplete without a trip to the dyno and the IT department.
Please be sure to select the proper bracket for your throttle body: 02-06 RSX Type-S (K20A2/K20Z1) are equipped with a cruise control type pulley (the bracket offset-compensates for this type of pulley). JDM K20A, Blox, BDL, and Skunk2 tb pulleys DO NOT have a cruise control type throttle pulley.
