I have been eating every one (pirate / AFA accord / Rosoko) mind for some time now about g23 etc.*

My reading brings me to this spec:
H22a block - darton replacement sleves - 89mm bore
K20 pistons - C/D - 30 - pin is same 22" and no issues with FRM due to sleves
*F23 race eng rods - again pin is 22" (same as h22 and f23)
F23 crank - 97 stroke - 55mm mains on a h22 block 1998+
Acl bearings
ARP bolts

Head:
Crower stage 3 cams ( i know not the best)
Super tech valvetrain
Port match - mild port work
header
BMC Street manifold
70mm TB

Now compression and numbers.*

Using CP flat tops - 11.42:1 ( almost perfect for daily driver running 87-89ron)
Gasket - OEM 3 layer (0.026)
Displacement: 2413cc
Rod to stroke ration: 1.45:1 -*
Mean piston speed: 2147fps
Piston to deck: 0.00

My GOALS:Stroker motor

RELIABLE

Make power 275-300hp

SO WHAT YOU THINK - such a mix would work? Is my research solid?Please discuss this*Kind Regards

 

Although this is probably a better question for the all-motor forum, I will give my thoughts in here.

First, you don't mention where you are, but is there better fuel than 89 available? If you can use 91-93, higher compression will help you to hit your goals, and make aggressive cams worthwhile.

Second, if you know that the Crower cams are not the best option, why not go for a Skunk2 or DDtech cam?

Do you already have the BMC intake, if not, how do you plan to acquire one since James is done making them?

You might have the best luck with this build if you ask NAH2B about N/A H builds, and what it will take to make your goal.

 

I appreciate the opinion. Am from mauritius small island in africa and our fuel is bottom of the can stuff... which comes from india.

Well the plan was to get better cams but my motor spun a rod bearing and got me stuck with this whole rebuild story.

I was among the few lucky that james was kind to make a manifold... I went all child and got his signature engraved on it... lucky kid in me I guess....

Am actually hoping nah2b sees this... and I get some info..

Regards

 

making 275-300hp isnt going too happen all motor on that fuel...
most h22's in that power level are on really high octane fuel and on way more compression and head work.....so look into that
maybe have a barell of fuel shipped out to ya

 

Our fuel laws are super strict.at best I could use octane at every fill up maybe get it up to 93-95 ron.

You see here they measure the ron value at the import docs which is supposed to be 95-97... now by the time its stored distributed and reaches us we cant say what value of running we got. Just to be safe I assume the value lower than it maybe.

Unfortunately I will have to set my goal lower nothing I can do about go juice...

Can any one advice on interchange or this mix of parts will they all bolt up no issues? Any experience

 

have you looked at toroc race fuel additives...
they call them shot's there somewhat proven like octane boosters...
there not gonna get ya to 275whp but it would help on the safety side...


you can also buy them on ebay

 

Interesting will check those out.

What power can I expect?

What is the kind of compression I can run safely on our bad fuel?

 

on bad fuel probally around 11.0.1-12.0.1....
i would expect 220-250 or so, pending on many things

 

Check my thread you'll see what it takes for a 300whp stroker h build

 

Can anyone cofirm interchange of these parts in terms of fitment..

Regards

 

F23 crank and rods in a H22 will require H22 pistons or cutting the block a butt load as the k20 pistons will sit. 040" in the hole. As long as the block and crank are the same size mains everything else should work fine.

 

Andy, thank you very much just the kind of info am looking for.

Well am sure out of experience you are saying is right. I just checked the comp calculator and it said piston to deck = 0.00 which i thought would suggest that they would sit perfectly in the hole. as comp height on h22 piston is 31mm when k20 are 30mm

I am lucky still have no ordered pistons - i read the six sigma racing build they used a h22a4 block with h22 pistons - they had to deck the pistons - how safe / unsafe is that / how does that effect reliability of the engine?

Regards

 

I DO NOT have personal experience with that combination. I just saw the comp height difference and assumed an issue. So I looked further into it and found that 30mm height pistons are need, not 31mm. The rod length different is only 2mm, but the crank is 3.15 (half stroke difference). Sorry for assuming first. I guess now we both know.

 

Thanks Andy....

You have been alot of help... Will be ordering my Ba lancer shaft elimination kit from you guys... Do PM me who is the right person to contact.

Kind Regards

 

Hey all,

Any one got experience running that crank in a H block...

Any other confirmations on the setup please help
