S model trany info

Have been looking everywhere for info on the 3g s model tranny but can find nothing, not even a trany code. Wanted to find the gear ratios on the s model and also to see if they would bolt up to an si engine because i want a longer gear ratio. Anybody have any info?

Re: S model trany info

My 89 S has a D2M4 transmission. I don't know any of the gear ratios. I'm running slightly oversized tires. At 60 mph it's turning about 2800 rpms. I'm planning to put stock diameter tires on it and I can post up more information then. But I need to buy some different lug nuts before I can mount them.

Re: S model trany info

I read somewhere once that it was a 4.29 gear ratio. Are you asking what the final drive ratio is? Most of us with manuals stock do 3000 rpm's at 60 mph. Don't know about automatics. Does your trans have the torque convertor lock up which people think is really a 5-speed auto?

Well that prety much throughs my plan down the toilet. I figured the base model would have a longer gear ratio. Just kinda wanted to find a way to get my car over 130 or at least be able to cruise at 60 at less than 2800.

Re: S model trany info

Yeah, the high reving thing on the highway sucks, too bad the Integra LS tranny's don't bolt up, 2800 at 70 mph I think? It's long.

Re: S model trany info

At 55mph (according to GPS) my D2j5 (B20a5 manual trans) the RPMs will be about 2450. Don't go by your speedometer, go with a GPS rated speed. The speedo can easily be wrong due to tire size and Honda made it to read like 1-2% higher by default.

Lol, sure Trip...let me just pull out my GPS. Oh, that's right, I don't have one.

I know for sure the speedo is off because of the tire size. I'm guessing it's about 3 mph slow.

Re: S model trany info

Like I said, Bone stock is about 3000 rpm's at 60. There's no way it's less than 2500. Anyone can hear the difference. Plus I am running stock 14's. 1-2% of 3000 isn't 500 rpm's. You could rotate the crank once and count how many revolutions the c.v. joint spins( or tire) while in any selected gear. That's the old fashioned way to find out what drive ratio you have. On rear wheel drive cars that's what most people do cause it's very quick. Too bad they haven't invented a 6 speed to let us do 1800 rpm's at 60 mph.

Re: S model trany info

The most fuel efficient speed is between 65-80mpg with these cars due to: a) Optimum engine RPM, and b) aerodynamics.

It is OKAY to do 3,000 RPMs in 5th gear if you have a PGM-FI. It gets better MPG's with the least amount of throttle and higher torque range. PGM-CARB is a different animal.

Re: S model trany info

Shorter gears are better for NA engine performance anyways, better acceleration, and staying within the powerband with each shift. One can look at the Type R/B16 tranny with a final drive of 4.70! Some NASA Honda spec racers even use a higher gear ratio in the ball park of 4.95.

IMO, the Prelude was deisgned to be a sports car, Honda knew what they were doing when deciding what gear box to put in the cars, focusing on acceleration and handling, not so much top speed.

Re: S model trany info

i THINK YOU'RE RIGHT. It's really not a basic Civic to get good gas mileage. Not engine wise but gear wise. Why do you think the h22a has 200 hp. It's gonna rev quick But it's also fun as hell. I get sick when I hear the teenagers with their little 1.5 litre civics making all that noise with the coffee can mufflers and never accelerate. The Prelude does accelerate. Oh......... Yeah!!!!
