Being that there is already and H2B discussion thread, i'd thought it would be nice to get a G23 thread going. being that this is a newer yet very fast uprising hybrid build set up coming up. I myself have just started laying out the plans for a motor my little brother wants and i will be assembling and tuning. anyone out there with some experience with these set-ups fell free to chime in and shine some light. my little brothers build will be f23 stock sleeves with bisi custom piston rod combo and an H22 head. so far i scored an H22 head in imaculate condition for $80 and a complete F23 longblock, which we are pretty much just going to use crank and block for $150. head will be going to RLZ for a nice port job, and compression we're looking at about 13:1 car will be tuned on E85 and going with the new hondata cpr backed up with an s300. going into a 95 DX coupe. only cut doors and FAL rear 3 windows for now. we will maybe cut it up and reduce more weight later on.

 

i'm collecting up the parts to do it too....i'm going about it a little different way i'm going to use f22 bottom end and h22 top end then i'm going to boost it 8/10lb...i'm putting it in an 1988 perlude si ..... i all ready have two h22a4 one in my lude and one i'm going to use for parts for this build

 

My setup currently
F22a1 block F20b head.
Items used:
h22 timing belt.
f20b timing pulley.
f20b water pump pulley gear.
f22 water pipe using f22 thermostat no welding but fabrications.
f22 head gasket.
The block is shot but will be rebuilding soon.
it was fast at first but since the block had 280,xxx miles it lost compression.

New setup:
F20b high comp pistons 12.24 in f22 block with f22 rods
SC14 Toyota supercharger custom fabrication done from a family friend
FMI with blow off valve
that's it will post pics

 

^^^^ you should post all the hard stuff ,i know you know it ^^^^^^

 

so looks like the bisi rods and pistons combo for the F23 were because of a big demand and were done for limited and now price is back up. $1200 for pistons and rods is not in our budget right now. being that i have a turbo car in the works. so my little brother has decided to settle for k20 pistons. type-s or type-r pistons will do for now. getting a nice port job on the head. messing with the intake manifold a bit porting it and gutting it and adding a spacer. and getting probably skunk 2 pro 2 cams. hopefully we can pull out around 230-240 from the car. with the car cut possibly get it to 1900lbs with driver in it should be well into the 11's with some seat time. lets see how this goes...

 

what i'm wanting to know, is what liter would an f22 block with h22 rod crank and f22 pistons be ?

 

Do you guys think the F22/F23 sleeves are good for an NA motor to a point, or can they handle anything? Do alot of the NA B and K guys just sleeve their blocks so they can bore it out some more or is it mainly for strength? I've seen some 300whp+ boosted F22/F23 wouldn't NA put less stress on it?

 

so whats the question^^^^^^^^

 

Can you have a 260-300whp NA G23 without worrying about cracking a sleeve (if you don't bore it more than 1mm over)? I'm going to build an NA motor, and option A is a sleeved H22 block or option B a G23 with stock sleeves. I think it was PirateMcFred build and he had 250-260whp with a stock sleeve G23, so seems okay but that is just one build.

 

you answered your own question... if PirateMcFred can do it then you can do it .... there are alot of builds out there that this is been done with turbo. so an na g23 that makes 260- 300 whp should be alright ....build it and let us know....f23/22 are cheap thats my reasoning....

 

I guess I will build it and see what happens.

 

when you do build it you need to take lots of pic and tell us all about the ins and outs of your build ........PLEASE..... when i start my build i'll do the same

 

Had that same turbo mAni lude72 cracked like a bitch fyi build truses (sp?) and itll survive

Im doing G23-2b-Turbo

Shooting for 300whp

 

i'm going to make a bracket from my turbo to my block to prevent that from happening ....thank you for the info .......

 

These builds will last long just get a good tune you will be good. My ecu is chipped and when i did my g22 swap i had to use my f20b chip because my h22 chip would not work on take off it bogged out bad so i switched to the f20b chip. It runs just like the f20b motor i had on my eg 4dr but it has more torque than the f20b. Runs rich but its fast as hell.

 

you ^^^^just need a tune for the motor your running...


RESPerformance, can we see some pic of your set up "PLEASE"

 

I can take pics im about to bolt the head on how do i make the pics appear here

 

Im a couple days from dropping it in

 

the tear down of the f23 long block and h22 head will begin this coming week. along with the tear down of the 95 coupe. looking for k20 type-s or type-r pistons at the moment...

 

mines not a g23. its more of a f22/f23 hybrid. heres some pics of the k20 pistons on f23 rods

 

^^^^^nice^^^^^

 

Im gna take pics hoW do i upload them herE.

 

I just finished building another G23 All motor...
Stock bore F23A1 block
K20A (PRC) Pistons
Still got the balance shafts in the block but removed the belt (Had an incident with the previous G23 and the balance shaft removal kit)
ACL Race bearings
H22 Head Cleaned up ports
Type S cams
Hacked and gutted H22 intake manifold (Soon to be done: K2h with RBC intake manifold and 74mm TB)
70mm TB
DSM 560's
RMF Replicas (Modified)
3" Exhaust
US H22 Tranny no LSD
6-puck sprung clutch, Lightweight flywheel

I'll post pics as soon as I can. By the way, it's in a CD5 Accord...

 

Currently this is my build using the f20b head= 85mm bore like the f22a1 that i have. I'm making a thread on my build so if interested take a look. Details and pics on it too. It's a little messy but will look a lot better once rebuild is done. Was thinking of doing my own wire tuck to it.

 

my g23 is getting closer too a dyno..hopeing for over 450whp on the nitrous
