Mk2 Focus RS gearbox to Zetec engine?
Hello guys , i think this could be my first topic , although iv been on here for a few years now i just normaly have a lookie at this and that.
Im after some info , what can , who can and best way to do what im thinking , dont like the cant words lol Long story short , i have a high powered mk1 focus RS track car , only issue just now is gearbox's , i cant seam to get the MTX75 to last any great deal of time. Now its down to torque , that seams to be the issue , the standard box was rebuilt , lasted 700 miles , quaife box was built , didnt even last a fraction of it. From what i found , standard box killed bearings really fast (i guess due to the horozontal and rotational forces placed on the bearings) Quaife dog box , a design flaw on 3rd gear - one which aparently isnt going to change So as another option iv been looking about to see whats stong as i know works , and it turns out mk2 RS focus's gearboxs seam to be fairly bomb proof with very little reports of failures , and the big powered cars run big torque figues due to them having that 5th cylinder haha Now external size wise they arnt much bigger , which isnt to bad considering they are a 6 speed aswell (but then we did have the 6 speed in the st170 that fitted no bother) The lists of parts that arnt a issue: Driveshafts Rear dogbone mount Top engine mount Gear Cables The main issue is bell housing, for three reasons ; 1. starter motor is on the other side of the box (on a mk1 its on the rear, mk2 its on the front) 2.Bell hosing shape (this i guess is issue 2 and 3) bolt pattern is wrong 3.Diff Iv yet to get a messurement , but number 3 might not be a "big" issue , IE if the center of the diff to the center of the imput shaft isnt miles out then it could work I could be wrong , but i dont think the bellshousing can be sorted with just a bolt adaptor plate like you can on a RWD set up If it could be them it would just be the starter motor issue and it could work Iv yet to think if a mk2 RS starter motor woud fit down the front between the turbo/manifold set up (although i highly doubt it would) Has anyone got any info or ideas , or knows someone that has done this or was atleast thinking about doing it , or would be up for trying to get it to work ? at a wits end tbh , and this is one last attempt to relight the love with my car ! (currently up for sale) Thanks in advance ! |
It would be nice if I could see your other thread.
Hopefully it will be sorted soon. |
Yeh I think 10 years of photos on the first page has killed the topic ! Iv asked for it to be deleted and il have to go back to the drawing board on what I’m gonna put in the first page |
Just start another thread and the mods will get around to deleting the old thread.

Try contacting Norris motorsport they do the mk2 box conv on s2's maybe they can help

I’m interested in this conversion... Ive messaged nms and had no replies yet Id love this conversion on the Orion |
Got to ask why wasn't the getrag 6 speed never used on the RS ?
I know all the dual mass is a pain etc can it not handle power very well? |
I was always led to believe the 6speed form the ST170 could not handle the torque.

Ratios are all wrong tbh, you’d be forever changing gear |
