Transit mk1 firevan/ 6cyl 24v bmw engine

[consul-ute]

Hello i'm hopping someone can help i've got a mk1 1970 lhd firevan twin wheel.i've fitted a 6cyl 24v 2.5 bmw petrol engine/5speed box but the axle ratio is too low geared. what transit mk diff could i fit. what van would it come from e.g mk2/3 van/minibus/chassis cab etc. heres hopping cheers pete.

BMW diff m8 really. most beemers gear boxes are same 1.6- 2.5l, its the lump n the diff thats the decider on speed.

could you fit 2nd gearbox? be mental to have TEN or 11 gears n 6 reverses!

Sorry maybe i worded this badly its got a bm engine n box but keeps the transit twin wheel axle. whats the highest transit diff/axle ratio n what is it fitted too. thanks again

[robbie.cee]

yeah i realise that dude, i mean you might struggle to match ratios if for example transit gearboxes have different ratios to bmw ones. dont forget bmw dont make vans but if they did theyd prob be 6 liter with truck boxes.... you might have to graft in the bmw diff if you cant get a suitable transit diff with correct or near ratio?


plus have you any pictures? was it much work to fit the engine? is it an m50/m52 engine? nice loud 6pot roar with k&N if its petrol

It was no big deal. I'm not trying to match the ratios just need to find the highest ratio axle / diff that was fitted to a twin wheel mk1/mk2 and what model it was fitted too. Thanks again Pete.

what about the soundproofing

[consul-ute]

Its having a bolt in gearbox tunnel made.

you will need to fit a rear axle from a mk1 or mk2 with the ratio of 4.63 ,this is the best ratio you will find!

great conversion

[pat stevens]

now thats interesting .should make a nice cruiser that one

[doggypaddle]

4.63 is the highest easily available for the twin wheel axle, still not really high enough for high speed highway cruising on 185,80,14 tyres but certainly better than the other lower ratios.
by my calculations in 5th gear at 5500rpm you will get around 100mph so around 20mph/1000rpm

probably a good compromise for speed and load hauling.

my dad had an old beamer estate he scraped, body was scrap but engine was good
the problem is im trying to find a replacement to my german engine but i dont want to cut the bulkhead and 2 litre v4s are quite hard to find

i got rid of a j reg e36 320ise for my transit. still glad i id it. shame i aint got a driveway else would have kept the lump g/box n diff meself. was sound always started first time, just bloody rusty body!... and tonnes slower than my e30 316i with high lift cams...(my beloved beemer ,eve)

still i think your onto a winner. take it its petrol. if so £25 quid nice k&n filter...vrooom!
