Stronger D Series Tranny

I am going to be building up a D Series SOHC VTEC Monster this machine is going to be turboed. This thing is going to be pumpin some high horse power. I know that with enough building I can get this motor to handle some good stress. But what about the Tranny? I have a 92-95 civic ex tranny right now that will need to be changed because the second gear scratches. What kind of tranny do you recommend I should change it to? I need something strong and I know the 92-95 trannies kind of suck. Thank you for your time.

Don't know what to tell you about stronger D-series transmissions. I hate them. My 2nd one is now on the way out. It now grinds when going into 2nd AND 3rd. Also sometimes pops out of 2nd gear when just cruising around a parking lot or something. I'd just say aim for that B18C1. I sure hope B series transmission are stronger. :(

Hey, what were your 1/8 and 1/4 mile times?

Well I have not clocked my car yet but I should be hitting somewhere in the high 15's a long time ago when I first got the car it had an intake and a short throw I was hitting 16.43 I just ordered an Unorthodox Race Pulley and I am going to also try thier Ultra Race Cam Sprocket. That was for the 1/4 mile time. I do not know what my 1/8 mile time is I don't have the slips anymore.

I've also been interested in changing transmissions in my 98 Civic EX. I was hoping for a close ratio transmission (at least gears 1-3), and possibly a wide 4th and 5th for cruising... Does such a thing exist, or can I assemble it. I want real, premade parts, no custom fabrication for me.

i would also be intrested in diff gear ratios for the d tranny

There is a tranny out there with closer gear ratio's and it is the ZC Tranny but I think it is a cable tranny but they should have Hydro ZC Tranies because they do make a 1.6 SOHC VTEC ZC motor for our car and they should have a tranny that fits that motor.

Why is it that everytime I post a question I never get an answer and I just answer other people's questions? Damn.

You're welcome. I checked out myself and all i see is b16 stuff. That shit is ssooo expensive!! Yeh check if they make stuff for your tranny...i'm pretty sure they do.:D

I e-mailed them and they don't make transaxles for my car. I need to whole tranny and I need one that is bulletproof. Dammit I am still in a search for the custom strong tranny for my car. I would like to talk to 13secondcivic and ask him what tranny he used to get his SOHC to run 12's

i heard im not sure its true that u need a longer gear ratio tranny like a cx, vx. I dont know why but thats what i heard..please tell me if im way off base.

Yea ur right. A tranny like the VX would be perfect for turbo because of it's "long gears". If you had a EX tranny and it was boosted then you would get through the gears way to quick and top out. I believe the VX does 40 in first, 70 in second, 100+ in third and im not real sure about the rest but like i said it has "long gears".;)

They prob have longer gears because they are 4-speed Trannies Correct me if I am work. Mine is a 5-Speed Tranny.

the cx and vx tranny comes with a 5 spd. its low gear ratio help the car to get good gas mileage. People noticed with longer ratios it helps the car stay in gear longer with a turbo/supercharger. Plus a little bit better gas mileage while crusin but i dont u care too much cuz u going f/i--force injection.

Thank dude for the advice that made since. I Will look more into it.

umm, I dont get what that has to do with your tranny problem. I mean you want a stronger tranny, the vx or cx will just ware out like the si tranny, Also I do not think that is a good Idea, My friends cousin put a sohc vtec engine into a 95" Cx hb, kept the cx tranny with the sohc and all he does is complain about it, I raced him and he takes me off the line but a little through second and a lot in 3rd I burn him. Not sure if it is something else but he complains about his tranny... Just my 2 cents

Not sure if it is something else but he complains about his tranny... Just my 2 cents, I too want to build up my sohc vtec, My b16 plans went down the drain when the engine smoked when started, So now I will go with the Gude bullfrog head, gains 49 hp off that, they guarenteed me 14's with exhaust intake, and headers, mid to high 14's actually, then a turbo and that will put me in the 13's hopefully. Then I buy some new cylinder sleeves have them bored to 82mm and get some pistons and its smoking z06 vettes for me. My advice is just to get an excedy or ACT clutch and deal with that, go get a new tranny, I just got one out of 99 ex, 9k on it for 175.00, The deals are out there go grasshopper....

you are right what does it have to do with a stronger tranny actually nothing to do with it. Stronger tranny is like stronger gears flywhell and also heavy duty parts from the clutch. We are talking about turboing a engine having a tranny with longer gears helps and i cant even tell you why cuz i dont know i read about it in many articals. What your friend has is n/a sohc engine. If he/she decides to turbo that motor with longer gears i think and believe that your friend do not have to shift as often and still have power at top it. I might be wrong if any1 know different please break it down for us.

If you want a "stronger" tranny, look for a good clutch, good flywheel and also have the gears heat treated... other then that not much else you can do...

Oh and someone mentioned something about shooting for a "b18c1" tranny... B series trannies do not bolt upto D series motors
