k22 275whp/ k23???

I will say once again sorry for my bad english.

Well, as I said in another topic would be builting K20 block
with F22c1 crank 87 mm pistons and custom rods.
2157cc.

good news:
cp pistons 12.5 comp. 87mm inlinePro rods.

f22c1 crank

I chose these rods because I could not find any stock.
It's a little heavy for 9200 rev limiter and
shorter than others because it is calculated with
oem piston height.
R/S Ratio 1.50
and for this reason we decided to revs to 9,000

bud news:

These rods it's not for ''any shelf K20 piston'' right?

here write this:
12 18 2012
New Extreme Power Rod part numbers in stock!
K20a2/K20z3
&
K22C1 Rods (Fits an S2000 F22C1 90.7mm crankshaft into a K20a/K20a2/K20z block using any shelf K20 piston)
http://www.inlinepro.com/s1/

What can i do know ?

Thanks guys!

nobody has an opinion?

jones83 · May 15, 2013

Always wanted to do a build like this. Very nice. It should be a little screamer. :up:

InlinePRO website says 'Pistons: Any CP shelf application(custom available 4-6 weeks)'. Maybe they meant CP shelf s2k pistons and not k20a?

I would contact InlinePRO first to see what they recommend.

Although disappointed it doesnt matter. i hope the next ppl to solve this issue with manufacturer before getting hold of these K22 rods.
This is and one reason of forums right?

Blazed · May 16, 2013

Did you contact them and explain the situation yet? I would start there; maybe they'll offer to solve the issue themselves.

:up:

K20actr.J · May 16, 2013

I am from Athens...
The only InlinePro answer:

''We make the connecting rods with a wide small end for strength using a 1.000" piston pin span. If your piston is smaller than that you can have your machine shop narrow the rod to fit the piston. This is very common and we do it on many applications''

I can not understand
A reputedly ready rod wants money again-machine shop again..

I try to find for what pistons are designed these widths of connecting rods????????
I carefully read the instructions...And just bought any shelf piston (cp 12.5 compr. with oem piston pin height)

As I said above kinds I've already forgotten

Rods have already gone to the workshop here

Delran · Jun 1, 2013

any updates, I'm interested in how this turns out lol

K20actr.J · Jun 17, 2013

for the moment nothing

Which factory can make custom rods 138mm lenght with correct piston pin height? I need to increase r/s ratio...
1.50 r/s ratio (with standard piston pin height) it's very bud for 9200 rev limit..

JDLR · Jun 18, 2013

Great build. Been looking into this as well. Can I ask why you picked the k20 block and not the k24 block?

K20actr.J · Jun 19, 2013

Because we here have no k24 block and is very expensive to buy
from other country and from second hand block...+vat etc..

snizzletoff · Jun 19, 2013

What oil pump do you plan on using??

K20actr.J · Jun 19, 2013

s2000 pump with all mods..i think erl make ready pumb with everything need to fit to k20 block!

snizzletoff · Jun 19, 2013

Figured that's the way you were going with the revs your planning for! :nod:

BlackNDecker · Jul 17, 2013

Why not just buy the assembled short block from ERL? They sell an 86 mm (2.2 L) block and an 89 mm (2.3 L) block. Seems like that would be much much easier than ordering custom rods and getting parts machined.

I also don't understand the point of a 2.2 liter build if you're just going to limit revs to 9000? You could do that with a simple 86x86 build. Not trying to be a d!ck...just curious.

The torque is much better than 86X86

same horsepower 86x86 at 10.000 rpm
same horsepower 90.7x86 at 9200 rpm
same horsepower 99x87 at 8600 rpm
same horsepower +++cc at lower revlimit...

For me the balance between revving and torque is this project.

Budget gets out ..
Do not forget that America is not near to me

SickSilver_ep3 · Jul 17, 2013

is this for a street car? road race? drag race?

trying to follow but where are you at with this right now. did you have the rods narrowed or are you ditching them and want a longer rod/custom piston?

K20actr.J · Jul 18, 2013

The car is for road race and traveling use.
I thought finally to keep the connecting rods and pistons...
r/s ratio with stantard piston pin height is 1.50.
With custom pin goes to 1.52 max
the difference is small
If the time was turning back, i would get other rods...
but now have pay these

SickSilver_ep3 · Jul 18, 2013

Not as bad as my 1.34 rod ratio lol.

venture210 · Aug 23, 2013

i like the idea of a happy medium with the 2.2 liter.

but seeing as how your doing it first hand, i want to ask if the main and rod journals are the same diameters and width as the k20z1,z3,a2 cranks.

what modifications do you need to do to the crank to make get the proper flywheel and crank pulley.

also seeing as how the stroke is 90.7mm, what do you guys think about a 2.35mm longer rod, and a 4.7mm shorter piston. this will give a 1.558 r/s ratio and should have clearance.

K20actr.J · Sep 2, 2013

I believe that if you make the piston so as you say .... life of pistons will be very brief
At the finish of the crank needs machining to get the crank pulley.
You get a k20a crank and a f22c in a workshop and the case is easy for them

K20A,K20A2,K20Z1 need the same modification
Here the different f22 crank and k20a-2 z1 crank

venture210 · Aug 23, 2013

also, with 136.65mm rods, (which is what i think this guy is using because of the 1.507 r/s ratio) did you have to have do any sort of modification to the piston skirts? or do they clear the crank counterweights.

venture210 · Aug 26, 2013

anyone????? someone please chime in

venture210 · Sep 4, 2013

thanks that clears up a lot, but if you use stock piston specs and shorter rods (136.65mm). i did the math and the r/s ratio is about 1.5 but will the piston skirts come into contact with the crank

K20actr.J · Sep 5, 2013

136.49mm. the lenght rod which I have.
I do not believe that which you say is right

Other k20 block have larger crank (along with other sleeves of course) with no issue contact with oem piston pin height..
for example bc

venture210 · Sep 5, 2013

i did the measurements using the stroke of 90.7mm and stock rod length of 139mm. in order for the piston to be level with the deck at the top of the stroke, the rod must be shortened by half of the new stroke minus the oem storke >>> 139-(90.7-86)/2= [136.65mm rod length]

with the rod you speak of being 136.49mm, the piston should sit just a tid bit lower than the deck but not enough to see with the human eye if all my math and specs are correct.

K20EF8 · Sep 5, 2013

I have a nice piston that could be used. ~25.4mm compression height, ~11.8 compression, you would need a custom rod, 141.25mm long, 260 gram 89mm piston. $1400 new from JE, selling for $600. Check my thread in the classifieds if interested. 1.56:1 rod ratio

venture210 · Sep 5, 2013

With that rod length, wouldn't the piston be really short and have a not last very long?

Well,i have ported rbc.

I need your help.
My project see it behind. To stay with ported rbc or put something else?
I want power everywhere.
But I want the best power 6500-9100 rpm
