anybody know of a place to get a b17 tranny? the reason i ask is because im looking for a cable tranny with b18c-like gearing for a jrsc b18c crx im building. ive looked everyone and i cant find a single one. the b16 trannys gears are too short for my liking and the b18b trannys gears are too long (goldilocks and the 3 bears, eh? ).

 

looked everywhere? my car has one. and to the best of my knowledge, my gears are identical to the b16 except 1st and 5th, which are actually shorter. 2nd, 3rd, 4th and final are the same.

 

search for ys1 (92 gsr tranny) hard to find is right since there wasn't a lot of the b17 made. i have one on my b17 it grinds third gear though. i might be selling it in a couple of weeks.

 

I seen one in
http://www.urbanracer.com
just search thru classifieds the guys name is dwight.

 

the b17a1 tranny is a ys1. But so is the 92-93 b18a tranny. The gearing is just different. So be aware that just because it says ys1.....it doesn't mean its a short geared one.

There are 2 downsides to the gsr ys1:
-they are hard to find cause they are rare
-they are older and usually have a lot of miles..... 3rd gear is characteristically bad with these trannies. So just assume that you'll need to be replacing at least your 3rd gear set in the near future.

It would probably be more cost effective, in the long run, to round up a ys1 case or one w/ bad gears.... for cheap. Then try to get the itr gears, cause they'll fit easily in the case (only a slight mod needs to be done). This way you'll have the itr gearing you want, it'll be basically brand new, and it may cost less than getting a ys1 and having to rebuild it. Just another option to consider.

 

a guy I know is currently selling one: http://www.g2ic.com/forums/sho...78274

as you can see they aren't exactly cheap.... even when not in perfect condition

 

what gears are the b18a most like? the b18b or b18c?

B18b

 

which would be better for my application? my project car will be mostly daily driven. should i get the short geared b16a tranny or the long geared b18b tranny?

 

you'll have to talk to the supercharged guys. Everything that i've heard has been..... if you go NA then you want short gears, if you go Turbo, you want longer gears. I'm not sure if that applies to superchargers as well or not.

 

it does. superchargers are only different from turbos in the way they are powered. turbo- exhaust, supercharger- engine

 

ok, thats good to know.

I know how a turbo works, and I realize how a supercharger works. But boost levels are different, and the means by which they are powered are different..... I just didn't want to speculate with the possibility of giving wrong or unhelpful info.

supercharger boost is relative to engine rpm since its belt driven; boost is always there and its constantly building if youre accelerating. turbo boost kicks in nearly instantaneously and is exhaust powered; wont have very much power in the lower rpms because of the long intake track and the time for the turbo to spool, but is more powerful in the mid to upper rpms (depending upon turbo size) because of the lack of parasitic drag.

then please share your recommendation with your reasoning

Thats why I didn't directly say that. Read my post again.....I only stated what is usually thrown around as the general rule (and I didn't mention it related to boost...only turbo) on most of the forums. And then continued to say that he needed to go talk to people who know more about superchargers than myself.

 

oh man i can see where this is going to lead...

 

this thread better not turn into a fireball slinging debate. now, is the b18a tranny from the gen2 teg a cable tranny?

 

90-93 cable...

 

shorter gears means faster acceleration no matter what. longer gears are more designed for driver comfort (i.e. not haveing to shift as often)

 

yes, all 90-93 b18a1 tegs had cable trannies. Hoever they are not the same. Gearing changes a little I believe. But more importantly the casings, internals and clutch disks are different (clutches are different because the spline sizes are different). The 90-91 trannies will NOT accept the itr and other hydro gears. Whereas the ys1's (92-93's) will accept hydro internals.
