best trasnmission

[GSR-b18]

Yes I have just bought a gsr engine for my 94 civic, i only bought the engine swap with out a tranny, i am now looking for a tranny, i would like to know what tranny would be the best to work with and also swapping, what parts would be the best to work with, wat to focus on, while figuring out the best for performance in it?? thanx

As far as performance, you probably would want the type R transmission. It has an LSD, with slightly shorter gears than the GSR transy. This will affect daily driving, you will rev higher than if you used the GSR transmission or the ls transmission. As far as fit, I can't help you there.

A ITR tranny will be best suited for you.

I run a y21 short as hell but a blast i need an lsd

If you want to turbocharge i think the ITR trannys gearing is too short so a GSR or LS tranny would do good for turbo. It all depends on what you want to do with your car. F/I? N/A?

once again stop sreading rumors and lies!!!!!!

With closer gear ratios, you are able to stay at a higher rpm in between shift points. Something like the LS transmissions are suited more towards the broad torque curve/low reving LS engine. It keeps you in the peak torque area in between shifts. The ITR/SI/GSR transmissions keep the rpm's built up in between shifts, to stay in the more peaky powerband.

Having said that, for the track the itr/si tranny is the best hands down. Most high whp turbo engines are operating between 5.5-9k, and having their shift points in between. In combination with a tall slick size (24.5"+), and the high shift point (8.5-9k), you are able to keep the engine operating within the optimum torque curve.

With the LS transmission, between shifts it would possibly drop you out of the optimal powerband and therefore make you slower. Gearing simply put allows you to stay in the powerband of your engine in between shifts.

The myth that you stay in gear longer with the LS transmission makes you faster is purely false. Think about that statement for a second. Acceleration is the measure of velocity over a unit time. Watching the rpms climb on the tach during a 3rd/4th gear pull, they would be climbing slower than with the si/itr tranny. Looking at the definition of acceleration as a measure of velocity over a unit time, the engine would be getting to the same velocity over a slower time lapse. This would yield slower acceleration, and simply put make you slower.

Having said that, the gsr transmission is probably the best balance of a street/strip transmission. The gearing is a little less aggressive as the itr/si transmissions, which will yield a little more traction. For all out acceleration si/itr tranny wins hands down. For a slower car, go with the LS transmission.

beat me to it
thanks now you sound all smart and i'm just like yea what he said...


well your right and good jorb!

dont mind me my brain is in the off mode

LS transmission is only good for gas mileage, constant highway driving, or higher mph. If you want acceleration, then the other b's are the only options. Even with turbo, you're still losing useful acceleration with the LS.

If you want to go all out; then get aftermarket hasport mounts and LSD (as mentioned).

Thanx alot this really helps me out now what kind of parts should i get for my transmission as far ass swaping goes if i do get a type R.

[CivicSpoon]

What do you mean? Like clutch and flywheel? Those are the only "parts" you can really get for a transmission (other than upgraded LSD).

hehe don't forget gears yummy 4.9 FD gears.

[iVteC_PoWeR]

oo really my bad my knowledge in trannys arent so great but thats why im here to learn. well as for me i personally still wouldnt get a ITR tranny because(im pretty sure this is right) the short gearing makes bad gas mileage.

thats fine but if your not 100% on somthing say so or don't post one one person knows everything. Most of your posts are pretty kickass keep it up and keep learning.

if you have a short range tranny for a long time you won't care about the milage its just ilke RRRRRRR snick RRRR snciks just fly through the gears its great heck i still do it

[GSR-b18]

thanks really again, yeah now my decission is somewere between a itr or a type R? Im trying to take out type S's here..

[GSR-b18]

So over all let me put it this way what tranny or trasmissions better said are better from best to worst, b16 CIVIC SI, b18c GSR, b18b LS, b18c1 Type R, and why, sorry on such of amature questions, im just trying to get it together here.. I APRECIATE YOUR HELP.

that can't really be done with out telling us a goal

if your just asking for what we like i'd say I've never been in my car with an ITR tranny but i bet it would rule I liked my gsr tranny but my b16 one is just silly for accelartion is kinda a pain on free way but i deal.
