I am thinking that I read somewhere that L'Natural pumped 250-260whp out of his H22. It seems low to me because they have gotten 256whp from a B18. Has anyone seen a built N/A H22 with closer to 300???

 

I've heard of one that's coming out next year with over 300HP.. It's been engine dynoed to over that.. Can't wait to see what it'll run

 

300whp is really hard to achieve with a 2.2 liter inline four.
even 250whp is a great number. yeah it's making a little more than some B series motors, but you gotta look at the torque too.
300whp is damn near impossible without shitloads of cash.

 

amen, look at the "character" of the engine... for that kind of flow you're looking at fabricating a large number of parts

EDIT: you're also looking at a completely different powerband... good on paper, not necessarily as good on tarmac

Actually team L'Natural is going to have more done to engine. They are going to be somewhere close to the 300whp range. The stroked 2.5l h22a is going to have a crazy 18:0:1 compressoin asswell with more work done to the engine. They say the car will be in 9's

18??? did i read that right? holly ****...

 

300 Hp to the wheels can be done. I have seen 290's... With a lil more R&D it is possible to make a lil more the 300.

 

oh yeah, it's possible. no one said it wasn't. what i said was it's near impossible without shitloads of cash.

 

there was an article in scc mag about 3 months ago with a profile of an italian honda shop that built h22 powered civics for endurance racing. The brief snipit said that the motors were built in england, they were 2l H22 s and they put out 300hp, the image of them showed a large, boxy, carbon intake manifold. i think the caption was somthing like: "get out your tissue boys...."

i searched the sccweb but got no results... send em an email if your realy currious

J.A.S engineering.

 

Damn...lot's of good input!...
OMG...that's without even stroking it!!!...


"Also Jeremy tells Street Tuners that the head work is where they have gained an extra 300cc's of displacement . {I didn't even know you could do that!}
Yes that is a 2.5 liter H22A prelude motor ."
"With high domed pistons with
huge cut-out reliefs in the top of pistons Jeremy says that his next engine is going to have an
18.0 : 1 Compression Ratio .
And he has some secret
head work planned for the upcoming season ."

The thought of 12:1 is crazy, 13:1 makes me shake...14:1 is unimagineable!!!

18:1 is MIND MELTING

I should be hitting 200whp next year will ALL stock internalls.... Stock pistons, valves, cams, IM, TB, cam gears, pretty much everything stock.. Yea, I know its not 300+, but then again, don't even think about street driving a 300+hp NA motor...

 

Found out some interesting stuff about my F20B crank/rods...based on that I should be able to make some insane power with the H/F/21/VTEC

 

when i get my h22 done i plan on having around 230-250 to the wheels, daily driven.. i have seen over 200 with boltons and a milled head on a h22

 

I think JG was hitting in the 250+ range with his NA setup..
but then again 13+:1 compression and 6 mpg using race gas is what you also have to accept.

 

But you don't have any accessories (PS,AC) attached, do you?

I guess that's about ~185whp for a street Prelude...

Please invite me out to watch the car dyno. I live just down the road in Durham. I would have to see that to believe it. I have never seen or heard of an H22 with more than even 215 N/A WHP being street driven on pump gas. I am of course assuming you are going to run pump gas. If not, then you are not going to be able to afford to drive that car very often.

 

I know Todd was at Full interior, all motor (nothing removed)

 

I dunno Corey...thats gonna be hard. I was gonna say, maybe if you got the Skunk2 manifold you might be able to make it along with SMSP's final header. But you listed stock IM...the only way thats even remotely possible is if you Port and Polished all of your "stock" parts.

 

Those 2.0L destroked H22's were in JAS's Accords, not Civics (the new EP CTR's will run the K20's they come with). However, those motors do have near 14:1CR and run ITB's. But if they were able to keep it a 2.2L, I think they would've easily hit 320+bhp...tho, not streetable at all.

Getting 200whp shouldn't be a problem as long as you open up everything for the intake stream. I'm getting 180whp with only basic bolt-ons. I'm hoping to get high 180's or low 190's with a port matched intake manifold and a ported throttle body. Keep in mind this is with a 1998 Prelude SH so the 4th gens and the base 5th gens will have more whp than I do. I loose around 22% of the power though the tranny (dang RSX's loose how much?? 15%... ) If I do hit low 190's cams should easily put me over 200whp.

 

In the touring car series the Hondas had destroked H22s to 2.0L with about 300hp. Now from what I remember they were only aloud so many motors during the year to keep cost down.

 

ill deff let u know when i get it done chris... btw, im jason... had the auto h22 accord.. been tryin to get pete's crx runnin right so much i havent had much time to think about my car.


as for my setup, im gona run s2000 pistons on the stock rods, custom intake manifold, skunk stage 3 cams, and a custom header for starters.... soon as i get that sorted out and save up some more money im going to ITB's and getting everything ported/polished.

 

The reason they did it was because the touring series required 2.0L engines...

I'm destroking my H23VTEC with an F20B crank to 2.1L in hopes of making so very high end power, stage 3 cams etc...

 

Hum interesting stuff guys. I have a 94 jdm h22 and im gonna try and see how much power i can get outta the stock block. Plans this winter are, full port and polish head, valve job, milled about 30k all done by port flow, then some skunk2 stage 2 cams,cam gears,springs, retainers and thier valves. Also there intake manifold with a ericks racing TB. Then a Jun header and a p30 with hondata should throw it around 220Hp at the wheels. What do u guy think of that setup??? And if thats not enough power ill do a 90mm block with some 12:1 pistons..hehe. I cant wait to tear it apart.
