Full QSD H2B Ek write-up (56k No way in hell, over 65 pics.) Enjoy. - Honda-Tech
jr_deleon's F20b build (2141cc 12.2:1 compression 1.69 r/s ratio) - Honda-Tech
Keep in mind that the F20B really hasnt been leaned on very hard so alot of the power has yet to be unlocked through testing
The H22/F20B motors are seeing daily progress from all the civic/integra drag racers who want more torque but dont want to spend 8-10K on a K swap....you are going to see some pretty trick stuff being tested this year and as more development on the K happens alot of those parts will be adapted to fit the H22 head....namely manifolds
Jr deleon is actually doing ALOT of testing for the community to help everyone figure out which combos are gonna produce the best gains ....from that we can gather which parts are most cost effective for various power levels
This is still fairly new territory considering these motors have been out of production for some time now....but better late than never right? lol
