Anyone noticed how cheap the 6 speed boxes are for the M3, Lexus etc, loads not even getting a starting bid at £100, surely a good option for the cossie ?
Why's no one doing this ?

are they a 1 peice bellhousing ?

how do there starters mount ,

granted anything can be modifyed ,but its best to start with a box thats adaptable ,


any links to said boxes mate,

Thanks for the linkies james, I just put a load into my watch list on ebay, very very few sell even at £100 start, some even less, I'm willing to bet the beemer box, a ZF ?, I assume is a ace bit of kit.
The ones I looked at had seperate bellhousings, there's even a auto cossie box on at the mo from a sapphy, and a rebuilt std T5 at £1,550 starting bid wtf!!

intergral bellhousings the same as the mt75's mean making them fit is a bitch

 

the m3 evo 6 speed gear box wont stand any abuice

 

m3 box to cossie engine has been done before ive seen a mk2 escort with it fitted, he broke the box not long after aparently they dont like the torque turbo motors dish out

 

id say that they brake in the m3's if there diffed much

 

so how do all these m3 turbos and supercharged m3s with 4-5 and even 600bhp cope if the box is weak?im sure ive heard of std boxes being used for nigh on 1000bhp in a 3.2.

 

dont know a few of my mates have them there gear boxes are allways gone they put the 5 speed boxes in they last a lot longer. whaen they are spending that sort of dosh id say they up rate the box just like you have to do with the cosse

 

g5 speeds are genrally known to be stronger than a 6 simply as your reducing the gear size to fit 6 into the same space as 5


bellhousings can be cut and re welded,

question is , is the box you plan to modify strong enough to go thru the hassle of modifying ,

Fitted a few now mostly on mk1 mk2 Escorts and Capris ect using both Getrag and ZF gearboxes. The getrag 242 262 265 all have seperate bellhousing using hydraulic clutch on the passenger side, boxes no bigger than mt 75. All versions already has provision for both mechanical and electric speedos to suit and you can buy suitable bellhousings off the shelf to most popular bolt patterns.

The ZF ones are much larger over all however bells is intergral and splines differ these are more risky to use because most used ones from drifting era already nackered and rebuild cost similar to uprating the t5 or mt75. The ZF have a nice slick unnotchy change unlike Ford or Getrags. These boxes are much longer too and funnily gear lever lines up perfect in transmission tunned whereas Getrags have extra bracket to relocate gear lever backwards that also lines up as standard!

 

the mark 2 was built by HT Racing if its the one i think it is

white one ,wide wheels and arches

 

Thanks esp TWoods for the info.

so we any further on to picking a box thats capeable of modifying and capeable of actually taking the power ?

ya go to reyland and fork out £11500 for there gear box central diff and eveything id love it for my car

 

paddy you woud if you were a big girl and only wanted a 4x4 !!


pmsl

 

you have the best of both worlds with that gearbox 4x4 when you want it and back wheel drive when you want to fuck about

 

Dont a lot of the BMW boxes run a 1:1 top gear ?

 

i've seen t56's converted to 4x4, do that to a viper box and it should in indistructable

 

The ratio's of a T56 are just about ok for a decent V8. Unless you run a silly short diff, they would be very very tall for a 4 cyl engine.


Do they just add a transfer box to the back of the T56 or what to make it 4wd compatible ? Would be be able to handle decent power ?

 

Not at all many have overdrive 5th, 6 speed gearboxes have 5th as 1:1 and 6th as the overdrive on both very cheap and easy to change the overdrive ratio.

 

Either ones i mentioned eariler can easily cope with the power and torque for decades without issue or internal modifications (as long as you start of with a good one)

 

yes they use a transfer case from the cyclone pickup so it can handle the power, i thing if u fine a good gearbox man its quite an easy job.

here are some pics of how its done http://home.comcast.net/~xr4x4ti/V8_AWD_Pictures.htm

 

the 6 speed evo box is shit in the m3 and they dont have any torque lol

 

Mmmm, I have a T56....now what to use for the front end lol Need either 3.27 or 3.55 to match my rear
