well today i'm putting the old Si tranny back in my car... depending how the clutch and flywheel look i might be installing my spare of both of those too...

can't wait to get rid of those damn dx gears


hopefully everything goes smoothly today...

Gunmetalef

good luck

imported_zc_hatch

get ready to feel the difference...
you should boost it dude!

turbo!

punkindrublic

ya i know it revs so crappily on the dx gears i ran into problems early on and took a long break... so i'm gonna go back and if i'm lucky it'll all be done for tonight...

as for turbo... no way... high rpm sounds much better then a bov...

imported_JookSingKid

are you done yet?

imported_loudsubz

i thought your si tranny was cooked

punkindrublic

man i'm really lazy today... i think i start up tomorrow morning haha

as for the tranny i suspect 95% of the problems were related to the clutch not lifting off the flywheel... but we'll find out soon enough...

even if it is busted though it'll all be coming out in a month or two so its all good... i'm excited about going back to my old gears though... now a days redlining first takes to past 70 kmph... but on the Si i'd barely be going 50

ya poor clutch adjsutment will lead to having the clutch not fully disengage therefore synchromesh can't engage....was it rough and hard to get it out and into gear..?? cause that is a common symptom of that....get a zc lsd tranny for N/a usage..

shlammed

if u were gonna go turbo you'd leave the dx tranny in for longer gears anyways

hey pm with info on engine specs for 92-95 civics

u doing a swap rick

Excuse me while I cure your ignorance.


If I EVER hear someone say this again im gonna


Ok. Lets get something straight.

Long gears = Top end runs
Short gears = Faster acceleration.

I know what your going to say and this is what it'll be.

"But with Long gears you can stay in boost longer".


WRONG

The misconception of staying in boost longer is only a resulting observation from using taller gears. How you say that you'll be boosting longer when it takes you 1 sec longer in the taller geared transmission to hit boost/higher end of powerband.

First of all, where do Honda's make power? High RPM correct? I've yet to see a Honda make more power at 5.5k over 6.5k. When you have LONG gears you will drop out of your powerband more often.

Plain and simple, a gear is a torque multiplier.

The higher the number (and thus, higher mulitplier), the shorter the gear.

A shorter gear will always out accelerate a longer gear, all else remaining the same. Fact.

For the street, consider drag radials, differentials, traction bars, and staged boost as the correct way of obtaining traction. Using a longer geared tranny is like reaching over your shoulder to scratch your *****.

wrong..^^^^ a longer geared tranny will always out accell a short ratio on a turbo car...both cases are true to a point but a itr tranny is not good for boost simply cause when you wager in transient boost time you are barely even lettign the turbo spool...you want high load on the turbo so....both sides are true to a point but generally you want a slightly longer geared tranny for boosted apps with large turbo's....

^^ no your wrong, theres a reason why the world's fastest hondas use type-r and SiR trannys. You create way more exhaust velocity at high rpm.............please stop mis informing people.

go tell them that an ls tranny is better, u'll get banned.

LOL ...

if you want to pick the correct trannie you have to do the math . period.

regardless of short or long gears the one thing you want is to keep the car's engine in the power band. whether turbo'ed or naturally asperated or pedal powered.

now how do you do this? well first you take your nicely built engine to a engine dyno and get a dyno plot of it's power done... notice I didn't say a chassis dyno where the power is measured at the wheels?

now that you have a dyno plot. remove the horsepower line it's meaning less

now look at the torque line decide where the power is. (not hard to do) now that you have the RPM range your making power in decide where you want to shift to the next gear. then do the math first you need to now work backwards. start at the wheels get the diameter of the wheels and figure out gearing ratios for all the gears so that your always in the power band. (you do this by selecting a gear whose low speed (km/h) will equal your engines low RPM speed ... anyways do the math and figure out the ratios you need then figure out where to get those ratios and build your own transmission ...

there's tons of extra details I left out here but thats because I don't want to go over everything ... I'm lazy one day I will

dingus88

and you think the worlds fastest honda's are using oem internals on those trannies.... or have a 8200 rpm redline...cause they dont'...so a short geared tranny when haivng a motor that rev's to 10 000 can be used to more efficiency...for the average joe a gsr tranny woudl be best using a smaller turbo yada yada...I dont' like the ls tranny personally...your an idiot slow eg cause not everyone has a huge T4 60 - 1 running a built 2.0 l gsr block with cams turning 9500 - 10 000 rpm's....

have you ever even driven a turbo charged car..?? cause I have and I can tell you that it benefited from slightly a longer 3rd gear to keep in in the meaty mid range...and to hold boost...why do you think dsm guy's put in a longer first gear..???when they build their trannies.....

mourad

Did anyone successfully achieve this? 'cause this would be quite a handy trick to impress the in-laws.

punkindrublic

why would i pm you info that is widely accessable on the internet? even on this very site


anyways why is everyone having little e thug rants in my thread? who cares if an ls tranny is better or worse for turbo then a b16 tranny? not me

besides didn't i already say turbo = no way??
