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!

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.

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

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

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.

Discussion do :nod:

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
