WHICH WOULD BE BEST FOR 1.9 CVH 15 PSI NOT SURE OF POWER

THANKS

 

standard mtx75 / cts stage two if it was'nt for the quaife diff i would say mtx75 but the a.t.b diff makes such a difference plus the mtx75 not a straight forward fit. i wish i could fit a mtx75 to my frst currently running a cts stage two plus but i keep on cracking cases

 

so a std mtx75 with a quaife diff in, is that the one..??

 

mtx allllllllll the way. Can run a nice big clutch for 40 quid from motorfactors then - won't slip and lovely to drive.

 

Defiantly mtx75 such agood box strong,nice gear changes, better ratios and like rick said clutch which can handle loads of power.

 

So where is the complexity in fitting these boxes, ie, why hasnt everyone done it ?

 

ya have to butcher yer chassis a bit to get em in, daresay that puts people off a little!!

 

are they good for 300bhp..??

 

no problem.

fitting wise, new mounts, convert change mechanism to cable, convert clutch to hydraulic, change flywheel...

 

And hybrid driveshafts...

 

coolio... anyone do a kit..??

 

i know that jano at oddkidd creations has done this a bunch of times ,

also simon at sas (sitech racing ) has this setup ,

you could try asking both of them , its deffo the way im going in my next project ,

boxes aint cheap but then neither is a stage 2 cts box ,



you can also use the 6 speed box from the st 170 .

 

Is the st170 a mtx-75 gearbox then ?

 

as far as i know it is yeah ,

know a lad running this setup in his track car , 6 spd 170 box

 

i think theres a bit more to runnin a st170 box, on a cvh anyway... starters at the back for one...!!!

 

What about fitting these to a zetec turbo install then? How difficult would it be ?

 

weve got a st 170 box in our track car, also sitech racing has got one in his. you probably better off askin him about fitment as weve already cut our chasis to take the mtx 75 then decided to go st170 route .

mind you not run our car yet. so dont know nufin bout ratio's and stuff

 

ST170 is not an MTX

 

so what is it then?

 

st170 is a getrag box
i did know the details when we was looking at them. but that info has been pushed out of my brain now to make way for somthing else.

 

and i think the torque rating is lower - which is why it wasn't used in Focus RS

 

ORDERED CTS STAGE 2 HOPE IT SORTS IT
