type-s pistons with .25 over bore, are you getting head work done? or just upgrading the valve train? if not DO IT! read Mr. Kidds guide to N/A power great resource

you can't overbore FRM sleeves. SOMETIMES you can get away with a light re-hone of the cylinders and run new standard size type S pistons and new rings. While you're at it, go ahead and pick up a set of eagle esp rods and ACL bearings. My last H22A I built was a jdm type S. I kept the oem pistons and got new rings, eagle esp rods, and acl bearings. It ran good until the kid I sold it to ran it with 1/2 quart of oil in the pan. He went like 20k miles without changing the oil. Then he tried to say that it was my fault since I built the engine myself.Originally Posted by IndianStig

i have skunk2 pro1 cams with skunk2's titanium dual valve springs and retainers and their flat face titanium valves..... im very disapointed with this setup only made 189 ( was originally 172 stock) to the wheels and thats with a dc header, 2.5" straight exhaust (no cat). I'm thinking about putting the stock cams back in, it ran a faster time with stock cams at the track as well.
somethings not right who tuned it? that should be a easy 200whp setup. are the cams degreed in and the engine healthy
everything on the motor is perfectly healthy it read 240 accross the board in a compression test and OEM headgasket, waterpump, and timing belt all done at the time of cams installation. One obvious factor to me is yes im still using the stock cam gears and they are set at zero degrees so playing around with adjustable cam gears should do something when i get them.
right there the cam gears are the problem you need some valve overlap and i bet you pick up another 10 or 15 but the car will have to be retuned again.
a intake manifold and 68mm throttle body wouldn't hurt either.
a friend of mines h22 picked up 12 whp with a 68mm tb and 3" intake over the stock tb (for a h22) and a skinny accord intake
So you picked up 17whp from camshafts an you are dissapointed ?
Thats a GREAT GAIN, id be happy. DO you have a graph of the old cams versus the new cams?
Ive dynoed an tuned alot of H22s an they make alot of power with PRO1s. Had a guy pick up 26whp once.
You cant compare your dyno with others unless its on the same day.
Different dynos are different readings.
Ive seen STOCK h22s make 190whp, and ive seen others make 165whp. It depends on the year, how healthy it is, who tuned it, etc.
I like the DC header because of its 2.5in collector and its cheap. Of course i would recommend SMSP but not everyone has $700 laying around.

Yeah i was really happy at the time i got it tuned that it made 17 more WHP but where i was disapointed is when i actually drove it. I took it to the track when the H22 was stock in my accord and it ran a 14.1 , i took it back again after the cams and it was in the 15's really ****ty, i dunno i feel a loss of power unitll like 6000 rpm and and VTEC doesnt even kick in until 6500!!!!
the exhaust should be fine ofcourse a better header would help you need to let it breathe it' can't get enough air thats the problem.
to the op camp1320 has a good h22 header and a few other companys have some reasonable priced ones old rmf etc
change your header to smsp and get a retune and see what happens. with head work and cams you can't settle for a dc header.
ps the dc header for the h22 is not 2.5" its more along 2" like the stock collector.

actually you would be wrong about this, stock h22 blocks with fmr sleeves can be over-bored. you just need to find the right shop with experience with fmr. any shop that build porsche motors can handle this.
also another option would be mahle gold pistons, they are made to drop right in to h22's without sleeving. They have low and high comp pistons.
About to approach beast mode
mahle gold series pistons are sold at summit also and for 563 for a set of high comp pistons is great consodering they work with the stock sleeves........ and porshe does run fmr sleeves along with mahle gold series pistons

I must say,out of all the stock honda motors(Not including k series),i like the h22 the most!!They not as expensive in stock form,compare to the other b series,and you don't have to rev the piss out of it ,to make power!! It's a very good track engine,because of there powerband...That just my opinion!!

MAHLE i think is the only company that makes those piston that are compatible with the frm. read a mag that did mahle high compression piston big dog cams and tune and made 210 at the wheels! they said they could make more but the stock intake mani chokes it
