JJ's Motorsports g23 and h23vtec h2b builds
im ivan at JJ's Motorsports. we got bit by the h series bug and are putting out several h2b setups at IFO San Antonio.the build i need to discuss first is the hybrid setup. im doing a g23 using k20 type s pistons (4.25 cc x 30mm comp) and type s cams. i will be using an h22 head with f20b cams and euro r manifold. i have under 4 weeks to build, test and tune. this will be a 100% extra shop parts build including the ugliest riced out 96 coupe in San Antonio that we got at auction. parts around the shop include
f23 long block
f22bx long block
f20b crank,rods,pistons,cams valve train.
h23 long block(non vtec)
k20 type s pistons (2 sets)
h22 head,crank, pistons,
k24 injectors (soon to be modded)
and so much more that i cant think of right now. ill post picks of the parts and piece of crap coupe its going in tomorrow. lol

You seem like you have done your Homework. F23 rod width is shorter like you state then H22/H23. I haven't played with the K20 rods but how much work will it take to fit a H piston on it?
As far as H22 type S pistons if putting in H short must be OEM not cheaper knock off's or will have issues with FRM sleeves OEM H pistons have coating on skirt for the FRM. Mahle Gold Series only forged piston for FRM sleeves. If putting the H22 type s piston in F23 short knock off will work but your boring from 86-87mm and I believe on the F23 that is maxing it out.
I would probably spend a little more then Delta for a bigger cam it wanting the most...

Rod widths
F23A - 19.81mm/.780
K20/24- 19.8mm (.780")
H22/ F20- 23.8mm (.938")
Crank Rod journal Diameters
K/H 48mm
F23A - 45mm
dam that sux. i was tired and didnt catch that last night. seems like the big end of the k20 rod is too big for the f23 crank . lol oh well a guy can dream. anyways that was just thinking out loud. this is the real setup im doing.
the bottom pic is an f20b intake against an h22. i also have the f23, f22b2 and an h23. still undecided on which is best intake manifold.
f23 crank and rods
k20 type s pistons +4.25 cc dome and 30mm comp ht 22mm floating wrist pin same as f23.
usdm h22 head with full f20b valve train along with f20b cams.

Re: JJ's Motorsports g23 and h23vtec h2b builds
im gonna b doing the same build
got my h22 complete head
also got me a complete f23a1 long block
just need
a new H22 timing belt
new h22 arp head studs
h22 water pump
h22 gasket kit
and f23 bearings
and im on my way
if u can, show how u plug the head and the way u mod the water pump
hey r u going to remove the balance shaft
i heard u gotta put the k20 piston opposite or upside down it that correct

Re: JJ's Motorsports g23 and h23vtec h2b builds
What about an F20B rod? Sightly longer(4mm), which would call for some custom pistons, but they're high revving already and come stock with rod bolts.
Also, I'm not sure which K series rod you're using in your measurements, but the k20a3 has the same BE and journal as the f23. ACL lists them to have the same exact rod bearings. The length is 5.551(f23) vs 5.453(k20a3). With the h22 type s piston, it'd put you at 10.1:1.

Re: JJ's Motorsports g23 and h23vtec h2b builds
You can not run any h22 piston not even a type s in a steal sleeved block will not work trust me ive tried it . Materials are not compatible just like you cant run a forged piston in a frm block . Call golden eagle if you dont beleive me and ask them . I got about 1,500 miles on each set before the pistons messing up. After three sets swqqpped to cp pistons no problems forn the last three years. Other then that you seem to have done your home work . If you can find a f20b block (I have three) it is alot easier to do these buids then the f23 block good luck.

Re: JJ's Motorsports g23 and h23vtec h2b builds
Im gona be doing a similar build but only with the f22a block. Build consist of f20b pistons and if i can i wanna use the rod bolts from the f20b to the f22 rods don't know if its possible but i will see. The setup is currently running and im using the f20b head it runs pretty hard right now but the block needs a rebuild the piston rings are shot and the block has 270,xxx miles on it thats why im trying the f20b pistons i have set.

Re: JJ's Motorsports g23 and h23vtec h2b builds
I bored my block out to 87mm and removed bs.
Im undecisive to use h22 pistons and custom cometic hg
or
buy a new block, have more fun removing bs and bearings again and using k20 type s keep the f23 head and go h2b...
Wdyt?
((sorry for thread jack))

Re: JJ's Motorsports g23 and h23vtec h2b builds
There is no "shelf" ARP fastener for the F23 rod. F23 bolts are not the same 9mm ones that 90% of K-series use. A while back though, gstrudler ordered some custom APR pieces for a much better bolt than stock. He may still have a couple extra sets. Do what you want though. F23 rods are still real skinny for high RPM work IMHO.
OE cast pistons have the wrist pins offset the wrong way too. They'll still work, just wear faster and be much noisier.

Re: JJ's Motorsports g23 and h23vtec h2b builds
one thing i noticed is using the f head bumps up CR in these setup by alot. oh dam i just had an idea. f22a head/f23 shortblock with k20 slugs and that gives you 12.34 CR and a 0.000 piston to deck height. all i would need is a cam. i can have a stock cam welded and grinded for 150$ at Delta. keep in mind that this is a junkyard setup so no expensive bisi cams. could i use f20b valve train in a sohc nonvtec f22a head?

IMHO h22 is the best just port the inside.
Also there was someone with a 300hp+ h22/h2b swap runnin' 10's around that offered services to make a custom' top part of the h22 IM.

Re: JJ's Motorsports g23 and h23vtec h2b builds
Most people seem to favor a good ported Euro-R or even a ported USDM manifold over the S2 or other IM's. Finding stock manifolds is pretty easy too if you don't have any around.
As far as rod bolts, I'm out of extras, sorry. There were rumors of ARP selling f23/k20a3 rod bolts, but I don't think it ever happened. Rods are going to be your weak spot if you want to rev this motor out at all. Either that or you're dropping $800 on Crower rods, which is sounds like you won't be doing either.
I think anyone will tell you to go the h2b route for racing if you have the resources. Good luck on the build
