My Future H22 Build.
ok guys today i bought a Jdm H22a from NAD AUTO. there great guys and very nice. recommend to all you i.a people that want quality engine. Compression Test Came out All 4 with 240.
but yeah enough with that. This is what i'm thinking of buying in the future:Crower Stage 2 Cams, Skunk2 Cam Gears, Upgraded Valve Springs and Retainers. and a great tune after that.
what do you guys think? will i need more parts or any suggestions? lmk
:idb:
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
skunk2 pro1 ret springs dc header tune that's all you need to do

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.
wow, my jdm h22a with NO INTERNAL MODS OR HEAD MODS made 180whp with i/h/e and just some brand new sparkplugs.
x2 (scratch the DC header though)
@ OP: If you don't mind me asking. How much are Nad Auto's H22a's
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.
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.

wow great info mr.kidd.
:idb:
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.
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!!!!
since when do dc headers come with a 2.5" collector???? buy a nice 4-1 header (rmf, prospeed, anr, smsp, etc) and some s2p1 cams and you should be around 205..
Hey Vteckidd... what is the most powerful h22 NA motor you have dyno'd?
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
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.

they do sell 2.5'' collector dc header now for h22. 4-2-1 design tho. i cant seem to find any 4-1 header for h22. found one thats for street racing purpose only. wont bolt up to the exhaust. thinking bout buying the 4-2-1 2.5'' collector dc header.
:idb:
no they don't sell a dc header with a 2.5" colector for the h22. you need to do some research bro....
you can't find a 4-1 dc header for a h22 because they don't make one. go on honda-tech or any prelude forum and search for header and you'll find out why noone uses a dc header on there build.
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

looks like your the one that needs to research more..
:idb:
all i know is michael montgomery made 26whp with PRO1s, over his stock camshafts. He had a RSR HEader which might as well have been stock.
They DO MAKE A 2.5in DC header, its 4-2-1, and its a great deal for the price. If you can afford an SMSP or HYTECH BY ALL MEANS, but lets be realistic, most people arent spending $700-1000 on their H22 or B series header anymore.
PRO1s
DC 2.5in Header
Tune
Start there, im sure youll see gains with the Euro-R manifold and a bigger TB. But i prefer most people to start small an work their way up

Wow that's news. They must of just started making those becuase over the years most people who have a greddy (which would be a better buy over the dc) or DC header would have an axhaust shop cut the collector and re-weld a 2.25 or 2.5" collector on to help with breathing when they do head work on the h22 to save money.
http://honda-tech.com/zerothread?id=218304
That's where I'm coming from. This dc header with a 2.5" collector is new.... (if you get it good luck with it but just keep in your mind whatever power you make you can make more a lot more.)
here is 18hp gained switching from dc to smsp
http://www.preludeonline.com/f60/h22...o-info-154398/
So I don't think I need to do any research because I already know that If I build a n/a h22 I'm not going to use a dc or megan or greddy or any other off the shelf header on my build becuase those header(s) are too restricted. Especially with the primaries, collector and there overall design. Well I guess not cause of collector sizes anymore since dc now offers a 2.5" collector that people have been doing for years.
Good luck with your build Bro!
thanks dude. reps to all of ya.
:idb:
the dc header has been out for almost three years FYI. It is axgreat budget header if to are looking for a sub 700 header

yeah. i cant really afford that 700 stuff. i'm just going to follow your info mr.kidd. can you sell me a h22a ecu 5spd that tuneable by any chance and header if you have?
:idb:
hey whats the pipe after the 2nd header part called? the one that i have on my car right now goes straight to cat so i will need to weld or bolt on a pipe there.
Mine looks like this right now.
:idb:
*****.. tell me who made the best WHP you have seen on a h22 all motor

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
if you want to put what you say your going to put, i suggest you to built the whole bottom end.
stock bottom end on a h22 is fine if you dont plan on revving it over 8k, like mr kidd said headers, pro1's, tune.
About to approach beast mode
I revved my h22 with stock bottom end other than eagle rods to 9k and above for about 5,000,000 dyno pulls on mainstreams dyno w/ mike
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
NO NWS
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!!

good thread
Trend settin'
for accord owners its either f22 single cam built or h22. the single can be beast with the right set up so dont sleep on them. check out bisimoto.com if you get change. the man is a sohc guru.

word.
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
