im not exactly sure what one to pair with my b18b1 motor, any advice is appreciated,

ttt anyone?

 

b16 gear ratios are a little shorter

 

Does the GSR not also have a LSD which the B16 does not? I could be wrong, it may be just the type R's that have the LSD...

edit: my mistake the B18C (GSR) tranny doesn't have the LSD...

However, if you can score a 2nd gen JDM B16A tranny the LSD was optional on those.

Obviously the type R woould be a sweet tranny to use but they are hard to come by.
I personally like the B16 gear ratio more than the b18...

 

GSRs don't have an LSD by default, although I'm sure some do, just like some B16 trannys do.

 

The only b series usdm tranny to ever get an oem LSD was the Integra type R.

In Japan, all B16A and B18C (both SiR-g and Type R) has the option of LSD and all Type R's

To answer the OP's question, a B16 and ITR tranny both do have shorter gearing than a GSR

 

Get a GSR tranny. A LS has a lower end power band, and therefore would be worse to have with a b16 tranny. As B16 gears are short, to take advantage of the B16's small powerband.

this will help some with gear ratios and speedvsrpm and stuff. If I am not mistaken, the type r tranny is the only honda tranny with the clutch type lsd? i researched that a while back but forgot now

 

I respectfully disagree.

IMO any time you've got an N/A (or stockish) or mildly boosted B series engine you want the shortest gearing possible IMO. The only potential downfall with the B16A/Type R shorter gearing and final drive is that the highway rpm when cruising is higher - sometimes too high for some people's tastes.

Solution?

Get the best of both worlds by using short gearing and a tall 5th gear by getting a B16A/Type R tranny and a 94-01 Integra LS 5th gear.

I'm building a 1992 Integra GS-R YS1 tranny (read Type R/B16A gearing with 4.400FD) and I'm adding the 94-01 LS 5th gear (tallest B series 5th gear) so
I'll be able to rip through 1-4, but have more tolerable 5th gear cruising.

I also own a 2001 spec USDM Type R transmission (bought it brand new back in 2004 or so?) and it's untouched internally. 5th gear is noticeably high rpm at speeds of over 60mph when compared to my current stock 1992 LS tranny in my daily driver.

 

well that is true. But it would depend on what they are looking for. And most people don't know how to build a tranny.

 

I look at it this way:

Even completely stock I'd take the shorter gearing all day, every day over longer gearing. Honda sold thousands and thousands of vehicles with the B16A/Type R gearing and had to stand behind them with full warranties, and even had to adhere to EPA fuel mileage ratings wars, etc. etc.

If a 4.400FD with a .848 5th gear was suitable for Honda's R&D department to be sold in millions of cars then I won't necessarily say it's a bad thing. Some people just want that extra bit of mpg for highway usage by having a slightly lower rpm at highway cruising.

BTW:

I'd have to see an actual scientific test that proves that a particular engine gets better or worse mpg at a given load/rpm. Some engines actually get BETTER mpg at HIGHER rpm because even though the rpm is higher, the load is less, and it takes less throttle input to take it up hills, etc. I did see a test a long time ago where a D15B7 got better mpg at a higher rpm than it did at a lower rpm. Of course there is a limit - I'm not saying it got better mpg at 6000rpm than it did 1500rpm, but I believe the figure was like 3800rpm or so when it was most efficient as opposed to 1500rpm or so that some people think would allow for crazy mpg.

 

Yeah, I agree with this, some people shift really early into fourth or fifth and then have to get on the throttle so much they're using more gas.

However, cruising at 4500 RPMs can be annoying for reasons like sound volume as well.

Back to the original question though, B16 trannies have shorter gears than a GSR which to me is more fun.
