hi, couple of my friends who have civic, is300 etc... can reach 80mph at 3500rpm
but my h23 prelude reaches 80mph at 4000rpm.. is that right? if its not, what could be the problem? thx

 

that's just how they are. they're geared lower for better acceleration. you might as well get used to it. the other cars are geared higher for a bit better gas mileage.

 

yup i think mines higher at 80 lol cool huh

 

my h22 is around that also, maybe a bit higher... they are geared lower for performance and acceleration... i also still get good gas mileage

 

You can put in one of the accord transmissions to get taller gears, but that kills your acceleration in lower gears too. There have been rumors here and there about people swapping tall 5th gears into VTEC transmissions to get good acceleration and cruise.

ALL H22 and H23 tranny 5th gears are the same. In fact, 1st and 5th gears are the same in the h22 and h23 trannies.

At 60, you should be running at approx. 3000 rpm. At 70, 3500 rpm, and at 80, 4000 rpm.

Not for all years. 4g VTEC trannies have an .870 5th, and 4g H23 and 5g VTEC have .812 JDM 4g and 5g trannies varry too. Just go by the tranny code and look up the ratios if there is doubt.

 

oh ic... good thing that nothing is wrong with my lude!! thx for all your inputs!!!

 

im runnin an h23 tranny on my h22a4 and at 80 im at 3700. if 4g h23 and 5g vtec are supposed to have a .812 5th then is there something wrong with my car???

 

Its just the gearing of the tranny, the only problem with the prelude IMO, well except for weight.
