When I bore my block im def going bigger and sleeving it so in the end depends on what type of work you are getting done

 

Try reading through the thread on honda-tech that was posted on the first page of this thread, the guy over there is running boost on his frankenstein. As for running boost in your CL, I would suggest turbocharging the f22b1 thats already in your 2.2.

 

if you dont remap the ecu to compensate for the runners being always open, you will loose power. top end is better but in the transition ti will fall on its face. you have to remap the p28 because its made for a civic.. your gonna be .6 litres bigger, the fuel maps are all for the smaller injectors, your h22 will run like ass on an unmapped p28.

 

just cause he's runnin boost dont mean it will last long. frankensteins yield ~11:1cr, thats way too high of a compression to boost on stock internals. it will spool up so fast and overrev your motor before you know it. it will work and feel great, but with anything more than say 5lb of boost, youll kill your engine.

 

im not saying not to chip the P28 to H22 standards but you dont need to pay an extra $100 for the dual runner control

 

What would the compression be with just the H22 head and no milling or anything done? I would like to be in the high compression area and yes before i boost i am rebuilding all internals.

 

thats what i was wondering as well??

 

im guessing stock f22 compression or h22
im confused now
sorry

 

the compression for the h22/f22 swap is 8.8.1

 

so with just the head it is 8.8:1... thats to low. So we mill the head .030 or .060 depending on what will get me into the 10-11:1 compression! Any idea how much would get me there? Anyone have a complete H22 head for sale?

 

Probably not worth it to increase the compression before you boost it. You will get more bhp for every pound of boost, but you would be taking a very serious risk by boosting a frankenstein engine with raised compression. For anyone going the turbo route, my opinion would be to stick with the f22b1. With a few upgraded internals, some very serious power can be made by the SOHC.

 

if someone did i would have been all over it already, so doubt it. how is that to low, thats good for turbo, which is what your doing correct.

 

Yes low compression is good for turbo.. 8.8:1 is right there too. Just want high compression turbo. More HP to be had. As long as you know what you are doing the risks of boosting a high compression motor are limited. And yes SOHC are good for the boost too but a DOHC Cl just sounds like to much fun. Especially when ppl think it is just a valve cover... I wanna know how much to deck the head to get to around 10:1 compression. You can safely put 8 psi into that on stock internals. I am rebuilding all internals so 8 will be no issue... I want the compression too b/c im not sure if i am going to boost once i do the head swap.. All depends on what kind of power can come from being NA. I would love to stay NA for awhile and get a pretty quick CL.

Silver check ebay. I was just there and there is one for like $550.. Guess all polished and yada yada yada. Check it out if you want

 

I don't know where you are getting the idea that you can 'safely' put 8psi into the frankentein with 10:1 compression and stock internals. The premium pump gas around here is 92 octane, and that certainly wouldn't be high enough to run that set-up 'safely'.

 

Yes it is... You can safely put 8 psi on a motor with 11:1 compression. Ive seen it done and it still runs. So 10:1 is lower and 8 psi wouldnt be an issue. Unless there is something weird with the H22 head it should handle it. Worst thing that happens a motor blows.. Oh no.. Lol

i meant to say ghost check ebay.. didnt you say that a friend of yours was selling 2 heads? what happened with that?

 

If you spent a whole bunch of time and money swapping an H22 head onto the F22 and raising the compression, then I'm sure your reaction wouldn't be "oh no..lol" if you blew the engine. From what I've read, running 8 psi on an 11:1 compression ratio with 92 octane gas and stock internals is a very unreliable set-up.

 

Ok well i know people who did it. And they have had no problems. The only thing is it is a GSR. Anything different between that and a frankenstein is something i dont know. It can handle boost....

 

get a GSR then
sell the CL

 

maybee cause the gsr has forged internals and is not a frankenstein.... your f22 is not forged, it will destroy itself @8 psi with the frankenstein.. you cant deck the head anymore unless you get shortie pistons.. or get prelude type r pistons., but then your cr will go up agian. plus if you deck the head any more your stock pistons will hit the valves on the h22 head. they are way bigger than the ones on the f22.

 

dont forget about a new clutch.

 

so yea lately ive been searching all over, asking different ppl if anyone is parting out an H22, i cant find shit. im starting to give up on this, unless i can find an amazing deal on a cylinder head im probaly not gonna do this. at first i had such a drive to do this but im having alot of trouble finding something to work with. i guess ill just have to make the best of my tired and modest F22.

 

keep lookin, nothing is ever easy

 

Not with these cars

 

yea tru, if i had a civic or something an need a GSR head i would be able to get one in a minute. H22's arent as common a B-series parts. so yea that sucks.

 

save your money
ill sell you my h22 for a good price once I throw in the fully built one

 

i want to put a gsr in to my rover. it has a d16 sohc in there now. (slooooooow).. but hey it gets 40 mpg, and in a country where a gallon of gas is 8$ (yes eight dollars.) im glad it does.

 

The H Series Head Cannot fit on the F series motor nothing will line correctly..

There is a dohc F22 made only in japan for the F series of course that will fit..

 

WOW

its been done and u still say it wont

 

go home... but search first..
