H22a build (mods)

[aussie_cb7]

ok guys here is another question for ya, i will be going for quite big power numbers with my N/A h22 (250hp+), what mods will i need to archieve this? and how much will it cost? roughly, cheers.

The whole 9 yeards. CAI, good header, straight-through exhaust, upgrade all internals (cams, pistsons, rods, etc), ECU, fuel system. You get my point. Basically going all balls out.

I dont think there is to many people on this board, I can only think of one that has made 250+ hp with a N/A setup. 2point6 is the name, I think he is at 280 something right now? Hes focusing on the k-series as of lately though.

I go to my local tuner shop and talk to the pros often, if you want to make big numbers your going to have build the head and up the compression, usually by changing the bottom end.

Skunk2 pro2's
Upgraded valve train
h23/f22 crank/rods
type-s pistons
Engine management/proper tuning

With of course all "good" bolt ons would net around 230-260whp. These were the numbers given to me by someone who knows his stuff. I mean there is a lot more stuff that goes into that list but thats the gist of it.

Look into depth with 2point6's h22 thread. he has alot of info about making the power N/A.

If you are really planning on making above 250hp NA then you have alot of work ahead because its not cheap or easy.

First off, You are not going to be making that power on a 2.2L you are going to have to start stroking and boring the h22 to atleast 2.3L. 2.44 is what 2point6 ended up boring and stroking his h22 to be reliable enough to not blow up.

And the parts to do all of this are not shelf parts either. You are going to have to start ordering custom 12:1 pistons, h23 or f23 crank with machining and custom rods depending on stroke desired.

There are more I just dont feel like typing it all right now

about 10g's after everything is bought, installed, and tuned

can someone please give me the link to 2point6's thread, thanks

this site unfortunately doesnt have much info in terms of NA engine building and tuning. you may be better off at honda-tech's website. just lurk, dont ask questions though.

alot of research needs to be done. and find a good tuner. Check out honda-tech in the prelude section there is a few threads with h22 dynos...it will give you an idea what you need to achieve 250...is that flywheel im assuming?

250 WHP is gonna take some more compression (Id go 12 ish to one), a set of healthy cams, headwork and a good tune. A nice header wiouldnt hurt either (not no DC sport junk...LOL) RMF DTR or the like... IT can be done though.... Then a 100 shot!! Fun times


Lookie what i found:

sweet cheers keep it comin

[mozzandherb]

ITB's would be a nice addition and also be very expensive

[aussie_cb7]

ok this is sounding like its gonna cost a shait load of dollars to get n/a power so might need to re think here, what about a turbo setup for the h22a how will that go do you think apposed to the n/a setup. should be alot easier to get the power but what are they like with problems?

[wed3k]

by the sounds of it, you'd b better off just turboing a f22 and callling it a day.

[aussie_cb7]

only prob with that is i will have to refirb my f22 (cause it has done close to 270,000 km) and that will cost me $3500 to do! where a good condition h22 is only gonna cost me $1500 ready to go in!
