gents and ladies. my series 1 turbo keeps lunching the second had gearboxes i am putting in it. the car is running 200bhp and and i do a lot of motorway driving where i will cruise at 90 -100mph.....

I am thinking mk5 diesel box? does this fit. Whats the deal with mtx75 boxes? are they stronger than ib5? let me know your thoughts....

cheers

 

Hi,diesel boxes are no stronger,i had exact same prob in my mk3 turbo i used a 92 casing,which the bigger bearings are used,ie input shaft,main shaft and one side of the diff,then u need to have the ib5 bearing pressed on to the non ground bc rst main shaft this worked for me untill i sold it on was holding 242hp and 270lbft failing that a chap in performance ford mag calls himself "gears" (01704535760)he will help you out as he did with me

 

i want to put a escort diesel gearbox in my siries 2 but dose any one no what clutch i need to put in it ie rs turbo one or a escort diesel one i mite sound megger dum lol but any on anythin ?????tar

 

why do people think diesel boxes are stronger!

 

you use the rs clutch but as has been said they are no strounger??

 

i for 1 know the diesel boxes are stronger as i built boxes for years

 

a focus st170 6 speed box would be good but i guess allot of work to fit it, This is something i will look into if my box dies.

Si

 

personally i dont care if the diesel box is stronger or not.... this is one of the age old arguments.... same as the whole whats less likely to break lsd and non lsd.... sorry dont want to start that one again!!!
my main reason for the change is the ratios, the mk3 xr3 boxes rev the nuts off the engine.... which is really good for drag racing and a thrash down the b roads! Unfortunately i feel I am breaking them by holding them too far up the range for extended periods of time.... plus i doubt its any good for the engine either! hence the diesel box.

cheers for the comments though, always nice when people show an interest!

 

WOW i started sume thin then lol dont get fiten lol i never said the diesel box woz stronger just cheaper lol thanx for the help a new rs clutch will fit thats all i need to no tar

 

i have been playing around with 4 speed, 5 speed mk3 boxes and then a diesel box in my cabriolets..

there isn t much difference between ratios of the normal box and the diesel box to be honest, the diesel box is stronger and can take more abuse as ive found out.
i currently use a diesel box, but thats coming out and i want to replace internals to sort me out with better ratios for 0-60 times, seeing as you cant seem to reach over 70 on the roads without getting caught anyway lol

 

lol well i put the diesel box in nw and it dose seam more nippy dont no if thats just me tho lol it works and drives thats what i wonted the only thing that had issue woz the trust bearing woz diff size so had to use the diesel one. But my next issue is me rear end when goin over a wet grid on the road it feels like my rear wheels are goin diff way than were i goin i thinken rear bushes ???? any tips

 

Give Bernie or Stuart a ring, tell him what your gearbox requirements are and power output and they will build you a gearbox to suit. I have got his gearboxes in all my Mk3 Escorts built to my ratios / final drives and never had a problem with them.
