Hallo,

i have a EE8 (EDM Model) with a Y1 (/wo LSD) cable tranny on a B16A1 engine.
And i urgantly need a longer first and second gear (or at least second gear) or a final drive which is longer then the 4.133 stock FD.

I've seen that Mfactory has a 4.05 FD, but it's mentioned only for hydro tranny's. Does anyone know where the difference is? does it fit in my tranny or can my tranny be modified?

I don't want to do a hydro-tranny swap, because i have a Y1 cable tranny as spare left which i want to use.

Can anyone help?

loonger second gear?do u mean u want it to pick up faster and go threw the gear faster.or u want long gears for boost....you can build your own and mix and match gears or ya get a different final drive...i was under the impression that the b16 trannys were 4.75 or somethin like that

You find different FD numbers about the Y1 tranny... but i'am pretty sure 4.133 is correct for mine.

With longer, i mean higher end speed at redline for 1st and 2nd.
Because of boost, the gears are only barely useable. Also with low boost, especialy on tight circuit tracks. First is hopeless but also less important, but i often have tight 2nd gear bends and there the 2nd is too short and brings too much tq to the wheels. Thats why i want it to be longer. Or a longer FD combined with a shorter 3rd and 4th (which is easy too find)

you could take the 1st and 2nd out of an LS tranny I think.

gears are to quick on a small track and to much torque on a b16...they put out 106 torque at 7 grand stock.low boost u probibly got 150 at most...sorry to be a dick but maybe its the driver or ur suspension setup...

you want longer or shorter gearing?? the 90-93 integra transmission has longer legs.

Check out or talk to the guys at MFactory

It's not about engine tq, it's about wheel tq and thats much higher then engine tq in second gear. But traction is not the main issue, it's acceleration time. First and second are just that short in comparison to engine power that you spend "more" time on up/down shifting then on driving in that short gear. It's not about suspension or driving, it's just a simple fact which can be measured by datalogging.

concerning the 90-93 integra trany?! What is the name of that tranny and are you 100% sure it will fit on my B16A1 engine and cable clutch? (to make it clear: I WILL NOT MAKE A HYDRO TRANNY SWAP!)

I had already contact to Mfactory, but if you take a look on their website, they only offer a shorter FD for the Y1 cable tranny and have no longer 1st and 2nd gear's. :-(

Thats why i'am asking here...

Their's a few ways you can go with this, have some custom gears made, swap in a tranny with longer gears, or pulling apart your tranny and by trial/error seeing what fits in there(my method). Ive came across an ls fifth gear swap before but not a first gear.

The edm transmissions Honda uses already have such tall gearing already, going even taller will slow down your acceleration, especially in the 1st two gears.

If you are looking for custom gears....contact "Gearspeed"

The jdm vesrsion of that YS1 tranny uses a 4.4 FD which would give faster 0-60 times, but have less top speed on the hiway

My Y1 LSD that came w/ muh JDM B16A Crx SiR swap = 4.266 FD (least that's wat specs say-never tested it) da other JDM EDM B-series (YS1,S1,etc) have the 4.4 FD. (USDM YS1,S1 = 4.266 specs say)

I'm uzed to D-series (LX in muh boosted sedan w/ pseudo lsd,and muh dohc zc,crx si's,etc...) I love the gearing in muh Y1,kinda right between da ZC + Si as far as gearing goes. (not quite as short as zc,but shorter than crx si) IMHO...

The Y1 comes with a 4.266 FD ratio and close shaft gears. Unfortunately, nobody makes a longer 1st gear for the Y1 and the hydro parts will not fit. The 92-93 YS1 cable box has internal parts like the hydro trans so you can switch to a longer 1st or longer 4.05 FD ratio. You will need to change the clutch to the 92-93 type but the YS1 can be built to meet your needs and will bolt right up.

^thuz why I take off in 2nd alot,useable 9.5K rpm range enables it easily...

You need a YS1. It is for a b18a but will work perfectly on a b16. it is cable/non LSD. Longer first and second for forced induction.

the 90-93 integra gs, rs, ls transmissions are cable and 100% bolt on. better ratios for what you are talking about. my b16 trans is ridiculously short and i'm swapping it soon.

Thanks for your answers. Unfortunatly the YS1 has the same gap between 2nd and 3rd as my Y1, so even if i get one (which is very hard in europe) i have to modify it which both together will not fit into my budget.

So, are there ANY gear set's (1st, 2nd or final drive) from other honda transmissions which will fit into my Y1 cable tranny?

Hope to get some positive replies... because i'am die because of that problem and it seems as the whole industry have nothing to fix, but i think a lot of turbo guy's have traction problems in 2nd, so it would be only logical to make it longer and closer to the 3rd... but all you find is shorter 3rd's and 4th's :-(

I also heared about some mugen gear set's for the Y1 which gives a longer 1st and 2nd, but i can't find them anymore... does someone know about them and maybe a source to get them?

There are two YS1's.

One is from the GSR integra, which has gears that are virtually identical to the CTR/ITR.

The other YS1 (I don't know why it's labeled the same) is like an S1, and has long gears (integra LS/GS/RS/etc).

I am considering swapping S1 parts into my YS1 trans to make first and/or second useful myself.

No traction there. Sometimes not even in third, under boost!

Deetz

You bumped a two year old thread, pretty sure the OP has figured it out by now

pkopalek

I will avoid doing that in the future if it is a nuisance.

For me, (as I have two cars that this directly applies to), I was doing research about this exact topic, and figured I'd add my findings, so that anyone searching through the threads can find the information.
