Ok so I figured I'd come over here where the real tech heads are at. Now I am doing this swap on an F22b1 block with an H22A1 head, All i have to do is get the head studs and the head gasket and i am all set to get down. I just have a couple unanswered questions i have no idea where to look for them.

I am suppose to swap the H22 water pumpgear to the F22, but the gear is hard enough to pull off of the H22 water pump so I don't think that I will ever get it off the F22 pump. So can I just slap the H22 pump on the F22 block as they share similar casting?

Second, Will the compression ratio be so low that it won't run well N/A. I heard the head alone will drop it down to 8.5:1 compression which i think is bull but absolutely great for boosting. Any insight on this matter will be great.

Thanks for the help HMT'ers!

Just use the f22 pump. The water pump gear has no role in the actual timing. It sits there and gets spun by the timing belt. It doesn't spin other gears.

The compression will drop even lower than what stock is, due to the h22 head having a 53.8cc combustion chamber vs the f22's 50.5cc. NA, it will suck *****. Mate it up to a better transmission and it won't suck as much. it will be similar to having a big cam on a sohc.

ive read that you also want to use a gsr timing belt

Ok, I did some research and people are using the h22 pump gear. Interesting.

Anyways, here's the of everything else you need

-h22 head (with IM/dizzy)
-ecu for h22
-h22 timing gear
-h22 water pump gear
-h22 exhaust manifold
-custom hard water pipe (have heard you can use the h23 therm housing and f22a1 hard water pipe but not sure)
-h22 timing belt
-f23 head gasket

There are also 2 oil returns that you have to seal off on the head.

Here's a link.

the gears are pressed on the pump, go to the parts store and borrow a gear puller then press the gear back on with a vise.

or take both pumps to a shop with a 12 pack and get it done.

don't jsut beat the gear off.

Yeah, I have the same checklist from the CB7 website. I am going to be using the H22 timing belt, as it came with the blown engine.

I also tried using a gear puller on the H22 water pump and it was almost impossible with as much pressure as i could apply to it. I will try again though i guess hahah if it needs to be done. But its supposibly something to do with the teeth and the amount of water that goes through and if i don't it won't flow as much i heard.

Yeah I heard the F23 gasket will show the Oil Returns pretty clearly and just goop some Honda Bond in there.

Other than that is it still driveable N/A I mean, because I don't want to do it and be like oh ---- now i have a car when i stop on the gas it takes like 25 seconds to go from 0-60. I've heard of people decking the head or doing something to the head, but I don't want to do anything to the block as I do not want to remove that from the car.

And thanks, alot of quick overnight replies hahaha

You could probably mill the head a few thousands to get it closer 9.0 at least.

Hahaha everytime i come on this board that avatar distracts the hell out of me but this is what i found out from looking at that thread...

He decked 35 thousandths off of the block, would the head allow for the same amount of milling? now i just have to find a shop to mill stuff at...Anyone in the Boston area know anyplace?

HAH, I soaked the water pump in some pb blaster while i went to walk the dog and get some lunch and i got it off with a lot of force and sacrificing a screw driver on the back side gear which isnt going to be used... Actually. I don't know that, which side IS going to be used the front where the timing belt goes, or the silver backside? OOPS! hope i didn't fubar that one up.

And timing gear is the same as cam timing gear? or is it the larger gear near the crankshaft? I never really got a straight answer... Can't wait to get this head on there..

stenseltizm

remember decking either head or block will ---- with the relationship of the cam gears and crank gear. It will throw off your cam timing. how much and if it matters depends on how much you mill. there are ways of calculating it... that i don't know off the top of my head
