Im currently building a b18, mine has the LSD as standard in the gear box, I used the original wiring loom & asked vdm motor sports to convert it to a stand alone loom, this was a lot cheaper than buying a new loom & an ecu the stock power should be enough for me as I only want to use the car on the road. I bought a complete car ( 1997 civic 4 door hatch back 750.00 ) then stripped it, kept the clocks & now wish I had also kept the heater !
Interesting to hear what other people are saying in regards to the difference between a 1.6 to the 1.8, in time if I get board of the power it will be more reliable to modify the engine with bolt on bits like a turbo and still give me plenty of smiles, Im using the clubman front, not sure how much space there will be up front for a turbo, maybe mount it where the rear subframe was. I wanted more power & more of an up to date engine thats reliable & fun, an a series with a lot of bhp can be a pig to drive in traffic, this should be a breeze when complete, Im down in Whitby if you want to take a look but its far from running yet

tbh when the engine is front mounted you will always be traction-limited to how much you can actually put down. My B16 with an OEM LSD will happily light up both front wheel in first and second (with 195 section tyres) from a standing start if I'm rough with it. I suspect that much over 140lb/ft and would starting spinning wheels in low gears whilst rolling. I'm not convinced a turbo B series would be a nice road car because you'd rarely be able to use all the power without it spinning up all the time. If you are going down that route then either mid mount it or convert to AWD using CRV running gear IMHO.

All the info here.
Let's hope you don't have the late Integra Type R S80 - it has the ultra-low 4.785 final drive

Further down that page - points 6.6, 6.7 and 6.9
All B16 engines are very suitable. Although the info states this should have a Y21 gearbox. Maybe the S80 was a swap, so it'll be hard to identify which FD you have

The S9B is more of a wide ratio that close ratio box which is what makes it better as it widens the space between the gears so works better with smaller wheels. Also it should be fitted with a factory LSD and a 4.2:1 final drive. Short of the Acura LS box from the US it's probably the best ratio box for a Mini if you aren't swapping to a non-OEM FD

I have gone for a S9B box as the ratios seem to work, however I have purchased an LS 5th gear to make crusing in 5th better. Keith went for this set up and he suggested his rpm is around 3500 at 70mph in 5th.

Unlike Keith I could not find a second hand 5th so I purchased a genuine one from Japan which cost me 130, so a happy comprosmise as changing the final drive would have been over 500.

According to the sticker on my gearbox I have a S9B in mine and I find it too low, you always feel like you are one gear higher than you should be effectively making the car a 4 speed. I found 2nd gear starts to work better than 1st gear starts.

I have to say tho' that I just get the feeling that I may have Y21 gearing in an S9B casing with the LSD from the S9B (I know it defies belief to do that but I just have a feeling ...) but I will know when I open up the box up to fit my 3.4 FD as I will count teeth to see if I am right
