Hey folks. I was wondering has anyone ever successfully fitted a 6th gear in to a b series gearbox?

I have a turbo'ed B18c4 and find I get through the 5 gears to quick. A 6th would be a big help.

Cheers
 
Not possible without spending huge amounts of cash I'm afraid as you'd have to go with a full on race sequential box... How about a longer FD?
 
A 6th gear would be lovely! needed for motorway cruising
 
Kswap will sort that haha :run:

This was my smart ass answer and you've stolen it from me!

In all seriousness I'd imagine the cost wouldn't be far off a kswap to get a six speed B box.

Only options you've got are longer FD or a longer 5th.

Actually I reckon k swap will be a lot cheaper, a sequential box will be north of £10k. Because b series motors spin the wrong way there's not an easy way of accommodating another box via adaptor plate either.

I was thinking more 6-7k but your probably right.
The above is going off a Quaife box I saw on the Interweb once so....lol
 
Cheers for the replays guys.

I did think it might be impossible but thought I would ask anyway.

And at 356 bhp & 300 ft/lb of torque a k swap would be a wee bit of a down grade for me.
 
Hi Guys,
Sorry to invade this thread, I have been through the site looking for information on B Series gear boxes but I still cant find a answer to my question.

I am looking for a Non LSD with a 2nd gear at 1.9 and a final drive of 4.2 can you point me in the right direction of codes etc and what models/year I would find these on in the UK of the USA?

Thanks In advance
John

S9B has these gears but it did come with a LSD, think mfactory do sell both a 1.9 and 4.2fd though?

So what gearbox can I buy that these will fit in to that are Non LSD?
 
Had a look on Mfactory, for that kind of price I am hoping to have 2 gear boxes haha:nice:
