ive got a 90 lude with an h22/h23 tranny. ive read different things about the best tranny for this engine. but when i first did the swap i had the h22 trans and my friend with a 92 lude w/ a jdm h22/h23 trans was beating me. so i pulled it out put a 12lb flywheel new clutch, moved my intake to a better spot and used the h23 tranny. after that i was smoking him. i gotta believe it was mostly the tranny swap to thank for this. anyone else have any knowledge about this subject? i would like to hear some more opinions on this. sometimes i still wonder if the h22 trans is better even tho i tried both.

 

H23 is geared longer.

H22 is geared shorter, thus being better (at least for all N/A applications). The only time a H23 transmission would be better would be if you were trapping 150+ MPH

 

what has changed with his car since you raced him? hopefully yall did more then 1 race with each tranny b4 you came to conclusions about who is smoking who. I would hands down say launch would be the biggest factor in who is beating who with similar cars/motors. If your staying N/A i would say M2B4 (h22a lsd) but if ur going boost i would say the h23 for the longer gears.

And how did you come to this conclusion I would like to know.

 

we raced at least 20 times before i changed everything. we raced froma roll and from a dig and he would beat me everytime. and his tranny was f'd up so every shift he would lose time and he would still beat me. he would always drop out of vtec when going into second. we both had 18's also. after i did the tranny swap and the other mods i listed i was blowing him away.

i appreciate the feedback but it seems most of you guys are speaking from numbers on paper but not from actually trying each tranny. like i said im pretty sure the h23 tranny is better but it seems that most people think it isnt, so i was curious if anyone else has had an experience like me.

 

Yeah I dont know,I have the same set up w the h23 tranny and I absolutely spank my friend chuck's 5th gen every single time we race,he has about the same mods as me,and we try all scenarios,from a dig, rolling starts,I have even givin him a car and caught him.What kind of tranny does a base 00 come with?

 

The gear ratio differences between a JDM H22, US 5g H22 and H23 tranny arn't that big. The M2F4 is a bit shorter than all of the above though.

 

shorter geared transmissions put more power to the wheels but lowers the shift point....so with a short gear tranny you need to rev it more. you'll get to your peak power quicker with a short gear tranny also but you stay in the power longer with a long gear tranny, but its transferring less power...you probably just gained more than you realize with that 12lb flywheel and intake. i've tried them all and the T2W4 is the best. now put the h22 tranny back on.

 

how did you gauge how much faster your car was to know which tranny was better? did you bring it to the strip or did you race someone before and after just swapping tranny's? thanks for the reply, im real interested to hear more.....thanks...dave

 

i just gauged it by the revs that the car is at after shifting.. since honda engines are generally peaky and just a few rpms can make the difference of 10's to 100's of hp you don't want to lose too many rpms between shifts... a shorter gear tranny like an h22 tranny has smaller gears and forces the engine to spin at a higher rpm at a given vehicle speed... so when you shift into second on an h22 as opposed to an h23 you'll start the gear at a higher power point in the powerband and you'll go quicker. theres not a huge difference between h22 and h23 tranny, but the accord euro-r tranny, which i currently use, is a badass. the 2nd gear is so close to 1st...i just use it as a really long 1st.

a problem arises with traction and fwd. generally, if you can hit shorter gears without spinning you'll be quicker...but since fwd is severely limited by traction you could run a tranny longer gearing so you'll go into the gear with less power but have a better chance for traction. its for this is basically why i use 2nd gear as 1st because its like a longer 1st and i get go a lot quicker than starting in 1st and trying not to spin and then have to shift.

thanks for the replys, but your really just going by your gut on which tranny is best. without going to the track, racing someone you've raced before or using a g-meter you really have no way of telling if you were going faster or not.

wrong.

 

I love when noobs reply to noobs and spread mixed truths.
Generally you don't want to do any "paper racing"

BUT...a gear ratio is a gear ratio...i can assure you that in your application the shortest geared tranny is the best.

There are many many factors to be taken into account as to why you now "smoke" your friend.....but putting in a longer geared tranny is not one of them......are you sure of the code on the old tranny you pulled out?

The 12 lbs flywheel could be the deciding factor here.

Is the H23 tranny the M2J5?


Modified by dc2vu at 1:20 PM 1/26/2007

 

usdm H23 gets an M2S4.

any chance of posting where all those other transmisison come from? I'll search anyways

Just like you don't know what the real reason is why you're faster than your friend now.
I bet that the flywheel and intake made more difference than you think, like someone has mentioned above. On an otherwise stock motor, the H22 tranny will render better acceleration. PERIOD. Go to the Integra forum and post the same question but about B18C1 and B18C5 instead of H22/H23, and see what kind of response you'll get.

What's the point of asking the question if you're not going to believe us. It's been confirmed a million times by now, take it or leave it. For your set up, the H22 tranny is better (unless you're planning to boost it). End of story.

 

is it true that lightweight flywheels dont give u any torque?

 

i updated my post

now has where the trannys come from

i'm going to make a thread for the FAQ since there isn't a complete list of all the H/F trannys in one thread

 

no they give u lbs of thrust...

Whats paper racing have to do with building a car? He just trying to state that you don't want to get into this paper racing or internet racing crap because its too subjective to the car, driver, and an number of different possibilities.

Did you change your tire size between the two trannies perhaps?
