i understand what your saying but for me i get tired of things FAST. so if a year or 2 from now i decide to boost that set up i wouldnt even look back at the money i spent on the head ect. i would be happier that i have tons of aftermarket support with endless amounts of turbo mani's, cams, valve train, with a unique set up
Every person I know who 'gets tire of things fast', owns a cheap civic, swaps motors here and there, and never holds on to one car for more than a year. Putting lots of money into something that you're going to get tired of quickly seem futile, but that's just me.
i FULLY truly understand where you are coming from but it will be fun for me to get the g23 to its full potential and when the time comes that shes all maxed out switch things up a bit the 2k, 3k, that would be spent in the process would be worth alot more then doing the norm if u get me
I don't understand how you consider $2000+ in parts for 9.7cr NA motor "full potential." That's mediocre at best. You could pull the head and have it shaved .020"-.030" to bump compression. My current head is shaved about .035", which theoretically puts me at 10:1. Hell if you just want something to tinker with and keep you busy, buy out my project (head, H23 IM, IM adapter plate, etc.). My point being, there are other mods you could do right now that would compliment BOTH N/A and boost builds. Besides, boring the block a full 1mm over, and boosting it on stock rods with domed pistons is a disaster waiting to happen, really.
Domed pistons are great for N/A builds. They're pretty much required. But, dished pistons are much more efficient than domed ones. Domed pistons are NOT good for boost, and even a slightly domed piston in a boosted engine creates MUCH more stress on components than a dished piston. If you read up on topics such as quench area, physics of flame travel, and side load, you'll understand why.
I think hes tryin to have a CR thats good for FI or NA. Honestly 9:7 wont bring out the full potential of the motor NA! Honestly its gotta be one or the other dude!!! For G23vtec seriously look at building an NA motor!
QFT. 9.7 is nothing for an all motor build. I bet my current F23 makes more than an H22/F23 @ 9.7cr.
...but for a fun ride i think the 9.7 cr with some extra work will land me me easy at 210whp. and still cheaper then a full h-swap
Cheaper than a swap, yes. Easy 210whp, keep dreaming. You're gonna need 11.5:1 K20 pistons, and a cam that's more aggressive than stock to break 200 without a LOT of other mods.
Then you should look at investing in more aggressive cams but actually some forged 10:1 pistons might be good, thats what Paul on V6p uses on the v6 motors he builds but I wouldnt boost over 15lbs.
The more aggressive the cam, the more compression you need for it to be useful. There are thousands of "Honda Guru's" out there with over-cammed motors.
