Motor all done and in car just need to tune.

H23 block at 11.7 comp
F22 balanced crank
H22 pistons
H22 stock head
Skunk 2 manifold ported to 72mm TB
Try Y duplicate header
2.5 straight piping
550 cc injector
Chrome P28 (not tuned just yet)

Hoping to hit 230whp...
Im going to go to church for the tunning.. unless anyone know where they can tune H22s better =D
What do u think ill pull after tunning? Sugestions plz =D I did past 190 on my last motor in a heavy BB6, not tuned n pretty much stock so I hope my expectations arnt too high =P

 

200-210whp on stock head and cams.

 

with cams and ported head 240-250 is possible

 

Better be an aggressive cam, plus a better header and 3" exhaust

 

H23V is pretty much right cams would be needed atleast pro1 this will yield probably 220-230 range. You will need atleast a 60k thick headgasket for proper valve to piston clearance. 3" exhaust is a must.

 

That 2 would help

 

Bizi is a known H/F-series tuner...

I need a Tune aswell but looking for a header first...

 

I actually have
f22crank rods / jdm h22 pistons stock headgasket i reworked the head myself just took out the casting lines nothing that i would say that would hurt the port. I have a custom h22 intake mani with the plenum and iab spacer cut wide open and the lower portion has 4 runners to the port. 70mm tb with a ebay header with 3inch collector and 3inch exhaust. I haven't dynoed but i did my own street/track tuning. I'm trapping 81.5mph in the 1/8th mile running 9.10 in accord that weighs with me in 2731. My mph/et/weight is saying that the car is making 207- 215whp and that's on street tires not slicks yet. So it's a low 14sec street tire car. Also i did track tune the car and basically kept adding fuel untill the mph stop going up and did the same to the timing ended up with 31.75 timing WOT running high 12's a/f.

Also running shell gasoline helped me gained 1.5 mph that nitrogen fuel really works. 93 octane.

Compression is closer to 12 b/c i got the head resurfaced.

 

I'm using the DH racing high comp head gasket, works fine so far n made a good difference on my last H series. And for the piping, I did want to do 3" but the guys at the muffler shop talked me into 2.5, guess they just don't have high expectations of our hondas =/ but little do they know ;D

As for the cams, I wish I was able to afford some.. ran out of money to do the head lol so mabye later in the future will see some, kept tryna find a good deal but no luck.

The guy at church sayed from that set up you could see 200-250 out of these motors, I agree but too bad I don't have the head work for the 250s..

 

I have pretty much your same setup only i tune with oem injectors,oem manifold port
atched to a 68mm throttle body and did 209 whp and 170wtq

 

Really, hmmm well I hope the little differences in mine help out hehe X)
Cuz on my H22A that did 191whp it just had a crappy DC header, intake, 2.5 piping n a fidanza flywheel, type S cams. Id figure that would do 200 tuned so I saw that compared to the new set up n guessed 230 would be a good aim.. but oh well will see once its on the Dyno =D.
I'm liking your torque!

I heard "Do It Dyno" does a good job tunning, a guy at the Eibach meet had a very similar set up to mine but a internally stock H22A n sayed he pulled 225 whp with the tunning n good bolt-ons

 

your using a 97mm stoke w/ h22 pistons and a thin headgasket??

what rods are you using?

 

piston to head contact ?

 

HOw does your car run untuned... I have a similar build any my car runs like dogg **** untuned... it falls flat up top and will over heat after about a hour or two of run time... it think the stock prelude base is too lean and I need some ign timing but I just wanted to know how these motors run untuned...

 

You're untuned with a setup like this and it run's like ****. I wonder why.

 

I think he said he has an F22 Crank (95mm)

 

F22 rods, n nope no contact, runs good on my accord ecu, only crappy thing though is that its slow for now. But I just took off the stock manifold n threw on the skunk2 manifold n TB. Had to cancle the ivac on the tb so hopefully that doesn't make a bad diff

 

are you using a 95mil crank or a 97mil crank?

 

f22=95mm. I wouldn't even beat on the car untuned. Thats just asking for trouble.

 

yep 95 n yea I'm tryna drive it as little as possible, u can feel the A/F really sloppy. It gets me from point A to B but does have alittle bit of a boggy effect like a boosted car running lean.

I need that tune soon! Hehe

 

High compression head gasket? this mean thinner then OEM?

For shitz and giggles I would do a compression test

95mm Stroke F22/H23 Crank and Rods with a H22 piston will stick out of cylinder 20k
Then your running a thinner then OEM head gasket?

The issue is you don't have atleast a 60k thick headgasket or some decent bowl work to the h22 head as h23v said above. However bowl work and stock headgasket still raises piston up higher and valve to piston clearance is crucial with stock OEM piston valve reliefs.

I would do a compression test and possibly a leak down. You definetly couldn't run any more agressive cams without a thicker headgasket.

Worse thing that can happen is in the higher rpm you start knicking valves then = bent and destruction

 

I was thinking the exact same thing. When I put it together I was sweating bullets on if ithe pistons would hit at the start, but the head had enough room especially with it never being resurfaced. N I also neasured it to compare the clearence. I've reved it up a bit but just not into the high zones till its tuned.. I've seen someone have to machine h22 pistons but it was because they used a h23 head, which has no clerance at all.
Let's just prey its all good ;D

 

Yea I'll say a prayer because the numbers of it isn't adding up... ask a few other builders PM nah2b he should be able to tell you straight up

 

i have a friends prelude i tuned running h23 crank and rods with Type S pistons on a stock headgasket without any issues. Been running for a couple years now. I dont see this guy running into issues if he had a stock HG/stock cometic or thicker gasket even with a set of cams but running a thinner gasket is a bit risky IMO.

Has the head been milled at all?
which h22 pistons are you using? A4? A?

Does ur friend have stock cams in it or aftermarket cams.

If u go beyond stock cams u will have problems b/c the valve releifs on the type s pistons have to be cut.

If he is using the stock cams it should be ok.

If u have jdm h22 pistons with f22 crank and rods and u go aftermarket cams u have a whole lot more room to play with and using stock head gasket.
