Prelude SI with S transmission - Honda Prelude Forum

autoluder · 04-19-2006, 09:58 PM

I couldnt find anything about this with a search. But does any one know if the prelude S 5sp tranny will make the SI any faster, by giving it longer gears?

The longer gears will decrease your rate of acceleration (read: can't speed up as fast), but will allow for a higher top end speed. I dunno if the H23 has a speed limiter or not... Oh and with the longer gears, you should get a little bit of help with Gas milage too.

Unless you have a specific need for longer gearing, I wouldn't do it. You're going to hurt your low end power, and the longer gearing isn't what the H23 was made for.. especially if you're going to be driving it hard... that means you're going to be spending more time in the higher RPM's due to a longer gear ratio = bad for H23.. they have a not so ideal stroke and are not good with long duration high rpms (at least in an unbuilt H23).

thanks, I kinda started this thread for me and my friend who has a si manual, and when he races like his friend with a old school altima that has a jdm motor, the his prelude finishes gears before the altima does, and the altima ends up passing him up every time the prelude has to shift. I just thought if there was longer gears that the car might have more room for each gear, but i guess that is a cost of having to rev higher more often

Your friend just needs to shift better then

In my situation I wish I had a transmission from an S model... 1st gear ends at 25 mph, 2nd gear at 55 mph.. I do nothing but spin all of first, and then half of second...

Well, you don't necessarily need longer gears still... you should think about getting an LSD/LSD trans instead. By just throwing longer gears at it, you're more like masking the problem rather than fixing it. An LSD would allow you to put the power to the ground much better.

true and true, kind of.. I prolly do need an LSD lol, but I don't have the money.. maybe when I replace the clutch one day...

if you whant it faster put a 4th gen vtec tranny in it it has the tightest gears of any usable tranny.

He doesn't want shorter gearing..

chester · 04-26-2006, 08:29 PM

So the h23 tranny is the best out of them all?

slipknot95758 · 04-26-2006, 09:02 PM

he whants faster, therefor he whants shorter.

GaRn · 04-26-2006, 09:44 PM

If you want shorter gearing than 25 mph in first then you are nuts, especially in a manual tranny...

If you had a 600 whp car and full slicks, I bet you wouldn't want to shift at 25 mph then at 55 mph... that would probably make you slower at that level in the game..

autoluder · 05-09-2006, 11:58 PM

seems like you just cant get ahead with preludes as far as using different car parts from different cars, unlike the civics and integras....

You sir, obviously have no idea what you're talking about.

Thanks for playing.

fast ≠ quick...

Land Speed cars are usually very fast, but not necessarily quick...

fast = top speed
quick = accelleration

S transmission = fast
VTEC transmission = quick

GaRn · 05-10-2006, 07:23 AM

S transmission = quick, when you have 400+ whp..

trust me, you don't want a 25 mph 1st gear when you have anything over 250 whp even..

You have no chance of traction on street tires, and you will be shifting more than going down the strip!

so H23 transmission=medium spicy?

See at least someone gets it...

relative to the rest, yes...

really though, you should choose your transmission based on your powerband... if you have really peaky power, you might want that VTEC transmission and a lower final drive... if your power curve is nice and flat, you can probably take advantage of longer gearing...
