Bense give DDtech a ring.... I like what he is doing with the H cams.... He has a few different options on custom cams he is making... he has one for this motor that I have seen on a semi build that keep the torque up... unlike others S2 which losses torque and makes peak power... DDtech seems to have a good idea on how to keep the low end and mid range power....

I swapped cams to EuroR/TypeS/F20BMT on one of the cookie cutter dynos I did not see huge gains... was minimal... however should show gains under boosted apps more. Current h23v bt build made 501 whp and 385 trq at 17 psi still uses Euro R mani and Euro R cams....

I just completed my swap last week. h23vtec BLUETOP in my 99 accord EX 4dr. I'm having an issue with the idle i think the IACV is bad but i believe the one from my f23 is the same so I'm going to swap it since i know that one works fine.

Good question the 3 wire IACV is found in the 98-02 Accords... H23V BT part number is same as 98-02 Accord F23 36460-PAA-L21 .... Also same as Euro R H22 Accord Motor
