DId MGV8s come out with them too?

I love the v8 versions they really have some good times on the track only bettered by big dollar big power modern race cars. Pity they arent more affordable.

I have an electric overdrive in my MGB,and it gives me 6 gears. Adding one to another gearbox isn't that straight forward as the mainshaft is extra long to engage the hub in the centre of the overdrive unit. Though it would'nt be impossible....with a bit of planning and machining. Cutting back the extension housing and welding a mounting flange might be the go. Problem is though that even these old units still pull good money with the classic car boys, or should that be old boys !!

$50??? I wish. More like $150-200. Sure I want a 6-speed -- direct 1:1 fifth AND overdrive.

The is300 (Toyota 2JZ engine) 6-speed I heard is the same gearbox used in the MX-5 Miata, Nissan 200SX and Honda S2000. This is the same basic engine (2JZ) as in the Supra and ES300 I think.

WTF!!!! Dd we here are hard enough trying for a 5 speed!!!

Yeah I know what it is you USA guys are sick of 63a and lesser 60a 5 speeds for 50 bucks on Ebay right?!!! while we kangaroo eating critters here fork out 3 times that for measly 4 speeds.

If youre serious then Miata or Eunos roadster as in Japan can be had for the price of a well sorted 1200 unless you go and buy one of a wrecker up there yourself or the triumph dolomite overdrive perhaps could be the go. personally Id rather fit a toyota 4 speed auto which has overdrive which has like a high and low on each speed electronically controlled the zaniest thing is how with it on my liteace van I can cruise in reverse the same as forward!!! with the same engine revs!! I had to back off after hitting 90 kmhr as I almost lost it.
Then run solenoid swiftches to your steering wheel a-la-F1. These gearboxes are awesome strong, flexible and compact.
You can also use a nissan 4 speed plush box but dont know anything bout them.

Excellent ideas, thanks. I don't have any special knowledge about 6-speeds for A12s ... sorry to disappoint ...

Any chance that the Lexus is300 6-speed uses the same bell housing as the T50?

What about an overdrive unit from an M.G or Triumph?

Lexus do a 6 speed behind their glorified camry too. RWD
No idea how big they are though

that would give you a 9 speed...
but its been done before... some dude wanted to have the lower gears for drag racing, and still be able to cruise, so he put two gearboxes in rather than swap diff centres every time he went down the strip... looked kinda weird with two quickshifters next to eachother, but apparenltly it worked well. (it was in an old chevy or something... don't think it'd fit in a datto)
only downside was the extra weight

The Caterham 7 uses a 6 speed. I think it's based on a quaife kit fitted to the Borg Warner type 75 gearbox as fitted to Ford Sierras. It would be relatively small. As for an A series box with 6 gears if you removed reverse there would probably be room to do it. I remember stories of "special " Mazda 6 speed boxes so maybe some one somewhere had a 6 speed Datto box built.

how about two 3 speed autos glued together...
