Jeebers that thing pulls hard to 120.

NZXTInerTia

It is seriously amazing NOT hearing a blowoff valve with that acceleration.

jdm92_accorn

Its much faster from 70-140+ with the windows up.

jdm92_accorn

i know its not much but i finally broke the 190whp barrier which is a goal i set for myself 4yrs ago. its funny i took out 1 degree over all and afrs are 12.5 wot instead of 12.8. but here it is.

AFAccord

Congrats! That's a nice looking curve too.

jdm92_accorn

I'm planning on a 3" exhaust and a 70mm throttle body. I've seen great results on stock h22's. As much as 4-5whp over a 2.5". It went from 175 to 180. Mine makes 190 with 100cc's more displacement, that coupled with a 70mm throttle body I think I might be able to hit 195whp. Then when I port the head and drop in some 09' tsx pistons I should see 205ish whp.

chrisnick

This is really awesome. Love the torque curve.

jdm92_accorn

Thankyou. The torque makes it very enjoyable for a daily commuter. It actually gets better gas mileage than when it was stock. Stock is 21city/28 hwy and now its 25city/34hwy. And it makes nearly double the factory hp. I hope to pick up a accord euro-R trans sometime soon and have it built by synchrotech and change my prelude shifter assembly out to the hybrid racing kswap assembly. With the trans and the shifter and some slicks I could see high 13's with a stock blocked, unported head f-series in an accord.

chrisnick

I bet you could go a bit faster than that cutting under a 2.0 60' time. I bet you can trap high 90's to possibly 100mph now. My RSX-S dyno'd similar peak power, but you have a LOT more torque. That car trapped consistantly 97-99MPH.

Also, since I can't post in your thread on CB7T(been registered for years but never posted), your power curves mimic your buddy's, I'd bet that you'd be making the same power as him with the compression he had, seems like there isn't a ton to be gained by porting the head with that cam.

That's quick! It'd give my H22A CB7 daily a good run.

jdm92_accorn

If I had 3" exhaust and 11+ compression along with displacement bump from the 1mil over to fit the tsx pistons I'm fairly certain I'd make more hp but probably less torque due to the header. I still can't believe after all that work I did he took it anywhere other than me to change his oil. Now he has that h22 in it and guess what, with his aem intake, upper plenum, 68mil throttle body a h22 megan header on his dp and 3" exhaust it made 178whp/145wtq and he said it felt way faster until he took it to the track only to find out it was .5 sec slower than his f was in the 170's. He says he's still happier with the h22. He's just a lost cause, lol.

jdm92_accorn

An h22 cb7 is a quick car. Especially if geared properly and with a good choice of tasteful mods. I went up against one last weekend. Street tire for street tire, he ran a 14.53X to my 14.499, he made me work for my win. His was a dx coupe with a/c & ps delete and full interior. He had dc header with 2.5" collector, 2.5" ebay exhaust, ebay intake and tuned on crome. He said it made 180whp, 140wtq and it was behind a t2t4 trans. It was funny though because I didn't at all expect it when he left me at the light and I walked him down. He did a 2.05 60ft to my 2.3xx 60ft. For those who know about drag racing, that's huge in the first 60ft. It was definitely a quick car. It definitely has me in the mood for a trans with better gearing and a lsd.

jdm92_accorn

Just thought I'd share, dynojets definitely read 5% higher than superflows.
It puts fact to the" it'd make xxx whp on a dynojet.

jdm92_accorn

Thought I'd share my almost 13sec 1/4 mile pass with a naturally aspirated sohc non vtec F23A.

Nice build, been following yah in CB7. Just amazed on how much HP/TQ from stock bottom end. I plan to build f23/f22a combo in near future with k pistons and bisi stg 2 and valvetrain, h23 IM, 70mm TB etc. I also plan to try and build my own header for it. We do custom fab in NC, so building a header won't be problem. Just don't have much R&D on what f likes. Did you ever do balance shaft delete? I ve done 3 lately to f22 and couple h22 with good results.

jdm92_accorn

It still has its balance shafts. I wanted a smooth engine because I dd it. If you decide to go with k series pistons I'd definitely use something bigger than a level 2. With 10.5:1 or higher the level 2 is too small. I'm planning to go level 3 or custom and I've only got 9.7:1.

jdm92_accorn

Finally.

I gotta 13sec accord, lol. Naturally aspirated, stock long block, sohc non-vtec, sleeper. It probably doesn't sound like much but it makes me happy. Especially considering stock it runs high 17sec 1/4's.

Congrats on hitting 13s in the accord :] What the link to your thread on cb7?

HiProfile

I'm surprised I never caught wind of your build until now - I love it!! I just keep checking the pages to see where you slipped in 12:1 compression pistons or ported the head. People never believe it, but the unported F23 head actually outflows the unported F22A head by a decent amount (mostly the exhaust) - there's just nothing for camshaft, intake manifold, or header options.

13sec non-vtec is always an achievement, but in an Accord with a SOHC it's up there. Thanks for posting everything so far.

Mishako129

Very cool what you did with your Cb.

I have a question however. What parts did you need to make the F23 work with your F22a head?

jdm92_accorn

just swap the oil restrictor, water crossover and use the f23 head gasket with the f22a timing belt. its cheap and straight forward. if you already have an f22 you've already got everything you need except the head gasket.

Mishako129

Uhh... what's an oil restrictor? And a water crossover, don't you mean the coolant pipe on the back of the block?
So you mean all the brackets are the same, the back T-bracket, the transmission mount, and the timing side bracket and the front bracket?
Because I thought I heard someone say that only 2 of the timing side mount bracket lines up.

GhostAccord

The oil restrictor is also known as the oil control orifice. It is located between the block and cylinder head. It is inserted into the surface of the block. You need to instal it into the VTEC block if you are running a non VTEC head. The non VTEC head does not require as much oil as the VTEC head.

Whether you call it a "Water crossover" or "coolant pipe on the back of the block" Honda refers to it as the connecting pipe and it connects the water pump to the thermostat housing.

Mishako129

"Oil control orifice". I know exactly what you're talking about. I actually bought one of those brand new from Honda when I did my rebuild.

So the coolant pipe is the same size as the F22? Cause I know for a fact the 2.3L H23 pipe is a bit bigger in diameter. The F22 pipes don't fit in the H23 engine.
