Haha, fixed. Musta gotten lazy on that last post

ok so if i wanted to throw in h23 internals in a h22 block i know it would work my question is how would some mahle gold series h22 rods and crower billet rods hold up do you guys think i would plan on getting thr 11.5 c/r all motor pistons. making my c/r around 11:1. do you guys think this would hold well without oil squirters?

its hard to say, why would you not just put the oil squirters in? same block different internals. the h23 hates being reved. if your building this motr i suggest getting the rotating assembly balanced and runing an after market harmonic dampener.

so what would the compression be on a stock H23 VTEC??

IOSUA

for a h23 vtec, do you have to tap a oil line to the head like LS VTEC???? does anyone know?

gah! im sorry but the repeated asking of this questions irritates me , the answer is NO! if you read the thread all of your future answers are in here. i think every new commer that does an h23 vtec asks this question. the h23 and h22 blocks are identical unlike the b18b and b18c.

edit: to answer you question above, look in the FAQ thread for h22 specs, and compression information then sue http://www.c-speedracing.com to figure out the compression.

ok ok ok, sorry. thanks for the info , but relaaaaaxxx

sorry man haha sometimes i get my panties all ina bundle and get irritated. neway, just look up the info its all around here.

no problem man. turboed my h23 vtec today. runs nice.

So picked up a 93 h23 today for 300 bucks for the whole swap... so ima get a h22 head and go ...h23 vtec in my 88 crx thanks for all the info fella's ...

how many are running a 89mm bore? if so what internals did you go with?

i cant find anything unless i go custom made.

prelittlelude

surely someone out there must make 89mm pistons.. there are alot of piston manufacturers and they carry alot of shelf pistons.. try these manufacturers first http://www.importperformancepa....html

weisco makes 89mm. so i will prolly go with those.

im using a H22a4 crank in the h23 block thats darton sleeved. im going to use the h22 piston, but waht rods? do they have to be h23?

no you need to use the matching rods for the crank.. if its h22 then use h22 if its a h23 crank use h23 rods.

Does the h23/h22a1 block accept the h22a4 crank without modification?....55mm journal and all.

oh good catch man.. yeah he has a point the usdm h23a1 blocks had 50mm mains and the h22a4 unless its a 97 crank it has 55mm mains if its from a 98+.. just FYI

I forgot about the 97 .

yes, just to clarify because i suck at posting, if you have a 1997 h22a4 crank it has the 50mm mains and will work in the h23a1, else not going to fit unless you have the mains of the h23a1 linebored out to 55mm

i had the mains machined to 50 from 55. it didnt cost much at my local shop.

i am using the H22a4 cranks. to i need to use the H22 rods. k thanks for the help.

to you recommend any company and why?

i thought of doing that.. did you have them just bore the mains exactly to 55mm or what was the measurement you used..

i am no expert on after market rods.. search around in here there were quiet a few good thread recently on rod selection.

Is there a good reason people go with the 55 instead of the 50 crank? Its just more surface area to keep oiled. The smaller the journal the lower the surface speeds are between the journal and bearing. If you go bigger, the surface speed will increase at the same rpm, yet will only recieve the same amount of oil.

Just a thought, i mean sure the crank might be stronger but for most of us its probably overkill right?

imo, i rather have the h24 crank. its safer at higher rpms or susposed to be.

with larger diameter mains in theory you have a bigger oil cushion for the crank to ride on.. but with everything there are deminishing return, 55mm is in no way to big, but the smaller diameter something is the slow the rotational speed at its most out point. so as you go bigger say you went to some cray 100mm mains or something the outer point of the main would have to travel extremely fast to move the same distance as the outer point of a 55mm main, with this faster speed there is more drag on the oil ..

i don't know why i went into that but basically a slightly bigger main gives you more cushioning and with more support supposedly you won't be as likely to have crank to bearing contact , hence less likely to spin a bearing

u mean h22a4?

the 98+ jdm h23 also has 55mm mains.

^thanks, for bring the point of using a h22a4 crank for everyone else to know. i was to dumb to type it out.
