I am doing a h2b for a friend now and i would like to see exactly how much power i can make on a stock bottom end he has a stock h23 vtec right now . He has skunk2 pro 2 cams balance shaft removal kit rmf header and euro r intake 70 millimeter throttle body. I have my head just sitting on the shelf id like to put it on his motor and port and polish his intake and see just how much power i can make with his stock bottom end that would be interesting also.

I do think that it has run out the hp limit on the throttle body but not the intake i think the intake is fine . Even the tunner thinks it will make five to ten more horse power just by changing the throttle body and exaust. The exaust is just some exaust shop two and a half inch bull crap with a cherry bomb lol for a resonator and a big muffler its real quiet.

Just so you know jensen me and my my dad is a fan of your work and respect your imput if you need anything are have any questions feel free to ask we will help as much as we can and i have a h2b kit at the shop if you need ant specs off of it thinking of making a couple myself. I have a ton of h22 stuff if you need it i got it. Also this motor is tunned on 93 octane no race gas thats why we only went to 12.3 on the compresion he drives it everyday gets 34.5 miles to the gallon. Ive also been running type s valve train with these cams for years works great just in case anybody has some laying around.

34mpgScotty rocks.
I didnt know the intake was all slicked up too, I just assumed after doing 40 hours on the head he might have left the intake alone to add an RBC or something else later on. I believe the intake still has some power left in it too. When you say stock TB, is that the little 55mm thing or 60? My stock intake entry and TB were 56mm for some reason. Maybe mine is just an old H22 intake? Its all 65mm now.
The big thing with the B series tranny is drivetrain loss, like you referenced. I believe they use about 3% less power than the M2B4, it could be more but thats a safe bet. I sent you a pm about the kit.
It is actualy a f20b throttle body which is 65 mm stock i believe .You can stick a stock 62 mm h22 throttle body almost inside of a f2ob.
