my question is my honda D16Z6 engine and is also automatic so will i get more power as an automatic or convert it to standard?? Also what is the difference between a cable and hydro tranny, and which is better?? If i swap an engine in which engine would be better B16A1 or A2 whats the difference?? Thanks

Re:Honda civic EX
 

going to 5 speed will give u more power at the wheels and obiously let u decied when to shift give u a better peforming car.the the b16A2 is newer and thats about it,a hydo tranny will mostly be found in92 and up civics and the cable tranny was mostly used in 91 and older civics.the diff. is a hydro trannies fork that pushes in the throw out bearing is operated my hydrolic pressure and a cable is just that operated by a cable the biggest diff is u will have more trouble finding a cable b series tranny than u will hydo,and the hydro is esier to push in the clutch pedal

Re:Honda civic EX
 

um ok
you don't add any horsepower from changing trannys. the gears might be different. also at WOT the auto tranny should shift at redline lol

Re:Honda civic EX
 

you dont add anny H.P with a 5 speed tranny but you do get more power to the wheels wiht the 5 speed.You loose some H.P with the torque converter in an automatic.

Re:Honda civic EX
 

thats what i ment,less to spin thats why i sed at the wheels the motor has less to spin :P

Re:Honda civic EX
 

yeah in the honda world Autos are slower then the 5 speeds...but in most performance cars....say 98-02 trans am/camaros , the auto tranny are faster..i guess because less chance of error from driver..plus those things blast out of the hole when they have a stall!

Re:Honda civic EX
 

the reson most higher powered v8 cars are auto is because just that stall...something we dont have to really dont have to worry about in vtec engines is the cam making good power from 1000-8000 rpms but with like alot of v8 the cam wont make any power till say 2500 then it will be real nasty in the top end thats why u need stall torque converters they dont even try to start moving the car till the engine is making power....try taking off at 2500 rmps all the time in a big car like that and see how long ur clutch will last

Re:Honda civic EX
 

i have a 2200rpm stall coverter on my chevelle. and it does make power before 2200rpms.

autos are for drag racing. you will never see a good dragster with a manual tranny unless its an import and they have no choice. no one can shift as fast as a turbo hyrolic 400 with a shift kit. its impossbile :)

the clutches in these trannies are made to be run hard. unlike OEM honda clutches

i'd like to see two dyno sheets of someone losing hp with an automatic tranny. i seriously doubt it.

Re:Honda civic EX
 

I was just wondering, ... how the hell does the blow off valve work with an automatic????? :-\ Can you hear it like a standard car when shifting??

Re:Honda civic EX
 

you guys are right in a way. a stock honda civic manual will smoke an auto because of of gears and launch.

Stock honda auto trannys over heat very easy when u push big power thru them. Build them up and you will do great. SCC is using a LS auto tranny on their stroker b16 holley drag car. to quote them....

"You can't beat the accuracy and quickness of an automatic slush box" and "the idea is never lift the pedal, spooled from green to the end".

Re:Honda civic EX
 

only when you let off the gas, you will hear the bov...

Re:Honda civic EX
 

the bov won't go off when an auto tranny shifts? i bet it still does.

Re:Honda civic EX
 

if it makes power before 2200 why have a stall converter why not just have the car start moving at say 1000-1500 but let me get this right say u have a cam that makes massive power from like 3000 or so to 8000 if u have 5 spd tranny and u try to take off at 1500 or so wont the car stall??

Re:Honda civic EX
 

not stall but bog

Re:Honda civic EX
 

a bov only goes of when the throttle is closed, in an auto car, the throttle is open during the shift so there will be no bov sound, only when you let off the gas

Re:Honda civic EX
 

lol, the BOV will sound any time there is vacuum in the engine after getting closed to or having pressure, and the spring can push the air out the bell.

The automatics still have a shift point, they dont just magically appear in 2nd gear, you guys need to go back to trannies 101.

Re:Honda civic EX
 

You will also lose horsepower and gas efficiency with a Honda automatic. The torque curves are going to be identical, and the horse power loss is only because of the gearing.

Re:Honda civic EX
 

Anny of you guys ever driven a car with a Tiptronic tranny.I also have a 99 Passat with a 1.8t and a Tiptronic tranny.Its the best of both worlds!Its a 5 speed auto that if you put it in drive an push the lever to the side you can now manually shift the gears without a clutch.All you have to do is push away frome you to shift up and back towards you to down shift.Whats cool is that if you dont manually shift you can redline every gear and the computer will shift for you.Ive been doing some reaserch of the engine and tranny and theyboth will handel up to 300 hp stock :o

Re:Honda civic EX
 

Yeah but the thing that sucks is that you can't launch!!!! That can make or break your chance of winning!! My friend has a new prelude with that kind of shifting and he always gets taken off the launch...

Re:Honda civic EX
 

yeah but its an auto/turbo witch means its gonna lag anny ways but once the turbo spools up I would swoop right by you as you are trying to shift gears.I didnt say it was quick off the line but it deffenetly makes up for time lost once it gets going.Dont get me twisted,my civic has a manual tranny and stage 2 cluch.I'm just pointing out how usefull some autos are for racing ;DCheck this outhttp://www.vwturbo.com/totm/current.aspclick on the blue highlighted 12.8 1/4 mile @113.Not bad for a automatic 4 door sedan that weighs around 3500 pounds :o

Re:Honda civic EX
 

if the b16a1 and the b16a2 is no different in hp why does the a2 has 170 hp, and the a1 160? a1 cable a2 hydro

Re:Honda civic EX
 

I think you mean a steptronic transmission?

My sisters prelude has this; its a good idea (hell Porsche invented it) but I don't think its that great there is still a delay inbetween shifts especially during power driving. Her car definently feels slower then a 5-speed SH of the same year.

Re:Honda civic EX
 

its called a tiptronic tranny. And I also heard they are crapola!

to the guy asking why a b16a1 has 160hp and a b16a2 has 170 has NOTHING to do with what transmission is used because those figures are measured at the flywheel. before a tranny even looses 15% of it.

If all you can find is a hydro tranny for a good price you can get a hasport kit that lets you use it. It adds a bracket and converts it to cable actuated. The transmission itself is not hydraulic, its the way its used. all in the mounts for hydro cyclinder and mechanism.

Re:Honda civic EX
 

and back to the v8 thing and stall converters..... ok it does make power, but not like what it would make at say 2500 or when ever ur cam was made to start making big power,so u would want to get a stall converter that locked up at 2500 or the say time u got into ur cam power range right??? so that would make it so ur not farting down the track till ur cam kicks in so kinda like bang u have power and thats when the converter locks up(if im wrong about this im sure someone will be more than happy to corect me ;))
