not too sound like a dick, but.....

Instead of listening to "magazine builds" listen to some people that have actually BUILT some high horsepower NA engines.

"peggy" has the highest whp H22 in GA IIRC around 230whp with an OEM build.

The problem i have with this topic is that people are looking for big power "CHEAP" and it simply DOES NOT WORK.

Unless you have built a motor that ran well an has dyno charts to back it up, i suggest you heed the advice of people in this thread like Scotty, Peggy, and me.

To say their is "no machine work involved" when you are talking about "building a motor" kinda shows how much of a noob you are to building a motor. No offense of course. We all have to start somewhere.

You will spend $500-600 on machine work, if you dont, then it wasnt worth a shit. Theres balancing, decking, sizing the rods, hot tanking, etc. Theres other stuff like new OEM parts (oil pump, TB, WP, seals, Headgasket, ARP studs, Bearings, etc)

If you think you can slap a F23 block with an H22 head and make 200whp, good luck to you. It WONT HAPPEN. i dont care what cams or header you have, it wont do it and it wont last.

Based upon my EXPERIENCE, which is all i can go by, the KEEP IT SIMPLE BUILDS are the ones that last and make GOOD POWER. The ones that try to reinvent the wheel are the ones that blow up an fail at impressing me.

Look Honda DESIGNED a H23VTEC motor, buy it, you get your 2.3L and you get VTEC you get OEM Honda engineering which is better than you will ever be able to imagine.

Or

Get an H23 block for CHEAP, and do a hybrid H23 VTEC. but make sure you build the bottom end as the H23 rods and pistons arent so great.

OR

Get a JDM H22 with low mileage, do cams and a header an make 200whp, with OEM FACTORY RELIABILITY.

No one said that the G23 wouldnt make power, and no one is trying to rain on your parade, but most of us think you simply dont know what it takes to build this kind of hybrid motor. Speedminded is right, the F23 bottom end CANT rev high enough to take advantage of the H22 head that is built to rev to 8200. How can you sit there an say "i dont need to rev it to XXXX rpm to make 200whp" when you have never done it? The factory rev limiter on a F23 is like 6800rpm, what makes you think those rods will live at 7500-8000. Ask Type-Flaco on here or Emminodagreat how long F23s can last at high rpms.

If you want to do it, DO IT, no one is stopping you, we are just making sure you know what you are getting into before you start acting like you know what you are getting into.

If you have the money go for it an do it right. But i prefer to get the most "bang for my buck" and IMO, the G23 isnt up high on my list.

Good Luck
