So I know this is an age old question but I haven't quite figured out what I want. I want to start building a motor for my CD7 Accord. I want boost. I've heard that an F22 is better to boost than an H22. I heard it was because there aren't a lot of aftermarket engine internals for the H22 that will handle high boost.

I guess my question is: I want to build a high boost (build for 20 psi, run 12 -15 psu) motor, should I buy an H22 or an F22? And then for which ever one it may be, what kind of internals should I look for and where? I also thought about just buying a built motor from Gude Performance but I haven't researched it. Any info would be appreciated.

 

Well as far as ultimate horsepower the H22 will make more. But either build is going to be insanely expensive.

F22 does have iron sleeves stock which the H22 doesnt, but if you were doing a serious build you would want to resleeve it with better ones.

I would say there are more pistons and such available for the H22. Either way you are looking at like a $7,000+ engine build.

 

Holly hell! $7K plus! I don't even know what to say to that. I guess that's part of the reason most people pimp Civic's. Is it that much because of how much boost I wanna push? I'd really like to get the car into the 14's. 13's would be a dream.

 

I ran 14s with a H22 with bolt ons.

The type of build you are talking about is more like 11s.

Heres just a brief price list to give you an idea:
H22-$1000
Sleeves-$1500
pistons-$600
Rods-$800
Machinging-$400
Port and polish-$1000
Cams-$700
Valves-$300
Spring/retainers-$300

All that and you havent even started to piece together a turbo kit, and your transmission/axles would need to be upgraded as well.

 

Yeah I talked to the guys from Gude Performance and that's the same thing they said. Maybe I was a little over excited. I want to stay on pump gas for one. I'm now thining I'd like to stay F-series also. They said they could build what I want for the same price I could do it myself. I also don't really have the knowledge to do it myself. I'm thinking I may just save up and go with a crate motor. I don't know yet. Thanks. for the info.

 

It may make more sense to build a cheap motor and scale up the power slowly as you get used to it. If you spend a ton and go full bore then it will hurt the wallet really bad if it craps out.

I got a Turbo F23 Accord.
