H23 gen4 or h22 SH gen5?

Here's the thing...A few months ago I bought a super clean 97 SH 5spd. I love the car, but I remember my buddy's H23 having more low end torque and feeling a bit more nimble. Now this was a long time ago so maybe I have to drive one again and refresh my crappy memory. But I really hate to wind my car all the way to 5k to get the juice out of it. I love a revy motor, but in everyday driving, I prefer to have low end punch.

My questions are:
I drive about 42 miles a day, almost all highway: Are they both about the same mpg wise?

Reliability: I need it to be reliable, is there anything that typically goes wrong with H23 ludes? I think I read somewhere that they like to spin bearings.
My lude has been rock solid since I got it except for regular oil changes. And the PO never had any major probs with it (I knew the guy).

And lastly, are the H23s really that torquey or is my memory failing me?

Thanx in advance for your comments and help.

The SH is a lot heavier than a 4g, the engine is more powerful in the SH but I'm pretty sure with the weight difference the 4g is faster. A 4g VTEC is def faster than both base and SH 5g's.

i know with the added stroke of the h23, cylinder walls/piston rings wear faster....and if your going to be doing all those highway miles i donno if youd want to swap out the 22. dont know if thats correct or not as ive never owned one but...its my .02.

Thanx, I know the SH is heaviest of all thanks to the ATTS unit.
I don't necessarily want the fastest lude, just the torquiest, I guess I'm spoiled from driving my other car which is a Mustang GT. I don't expect the same low end punch from the Lude, but I remember the H23 having a nice low and mid range punch. I'm not very concerned with how they perform beyond 5k, It's a daily driver and speeding tickets are expensive as hell in S-FL lol. (I do love the vtec pull beyond 5K though, it's just that I spend 90% of the time under 4.5K)

thanx for that info zfinatic, I'll look into that.
I believe the H23 doesn't spin as high as the 22 at the same MPH though right? Because of the different final drive ratios? The 22 spins at 4k to go 80 mph. I have to look up the ratios of the 23 and compare, but this might offset the longer stroke issue when it comes to wear if the 23 spins lower at the same speed.

Also, no swapping will be done here, most likely I'll let go of the SH and try and find a clean 4g H23.

Nevermind the different ratio thing, the H23 and H22 trannies have the same 5th gear and final drives. Only the F22s have taller gearing. No wonder the H23 feels better down low, it's a lighter car, engine has a longer stroke, and same gear ratios.

4g+H23a VTEC+T2W4=what you're looking for.

pretty close...I would love the 4g+H23 VTEC part mated to an M2B4 so I can have a shorter 1st and a taller 5th.
Not sure how correct this info is but...

M2B4
3.307 1
1.950 2
1.360 3
1.034 4
0.787 5
4.266 final

T2W4
3.285 1
2.090 2
1.481 3
1.071 4
0.812 5
4.266 final


But my wife would probably divorce me if I start wasting all our money on my perfect little lude.
Plus, I'm too lazy to build it up anyway.

Or even better would be that motor/tranny in a 5gen on a diet that would make it 300 lbs lighter.

it's all about what you want the car for but a h23 4th gen?? not worth it because you will have to swap it to be quicker. sh 5th gen is better for handling i'd go with a 5th gen sh.Plus it has a better resale value.Most likely you will have to replace and fix a bunch of stuff on the 4th gen.

^You do know I meant the CH9 wagon engine right? It's a DOHC 2.3 VTEC, 200hp like the H22a but factory stroked up, japan only engine.

T2W4 in performance trumps the M2B4 in every way, more aggressive gearing and better differential, 2 stock 5g's with those transmissions racing, the one with the T2W4 would win every time.

An SH isn't that great, it only works when turning and a good mechanical LSD would go a lot further.

Oh, I thought you meant an H23 VTEC hybrid. Which would still be VERY nice.

I know the T2W4 will pull away from the M2B4...gears 2,3,4, and 5 are all shorter. But I would like the M2B4 cuz of all my highway driving. I don't race on the street and I don't do any tracking or autocrossing. I would rather have the slower tranny to keep the revs down at 80 mph. Just trying to minimize the wear on the motor.

Thanks for the info on the CH9, I didn't know Honda made an H series 2.3L VTEC . Wish I had the balls to try a swap with that motor...and the cash too lol.

Basically, I would just like a bit more low end grunt and a bit taller 5th gear.

I know, I know, you guys are gonna tell me to go get a 4gen with a SOHC F22 5sp lol!

yeah but the op didn't

atts isn't that great? then why do they still use something similiar to it today?
Have you even driven a sh 5th gen?

5th gen already has 5 lug, already has a h22 can't go wrong with it and like i said it will have a better resale value. Both cars you will probably have to do some work to them but you will have a bit less work to do on a 5th gen.

Factory H22 standard doesn't mean anything, most at this point are so high mileage to where most would want to swap anyway. I have driven an SH prelude, you couldn't give me 2 good condition ones for my 4g, 4WS was way better. I've also driven the newer AWD SH Honda's, it is better when all 4 wheels are driven.

I don't care about resale value, they're both old and not worth much either way, getting one and not planning to keep it is a stupid move. Could probably sell my 4g for as much as most 5g's go for considering my engine swap looks factory as well as it being probably the best condition 4g anywhere near here. I'm smart though, wouldn't spend money on a car I wasn't gonna keep.
