Greetings to all,im looking to V8 a sierra,has anyone done this or can anyone ofer info that may be of use regards engine mounts or why?
there's a knackered 24v cossie lump (4wd) in her at the mo and i am now going to do what i should have done in the first place,slap an 8 in the bugger an go 2wd

It's an easy swap if you use the Magnum engineering kit and the T5 Cosworth box, I did it a few years ago and it makes the Sierra into a very good car The T5 means you can use a standard Cossie prop and the gearstick is in the right place in the tunnel.

Cheers Mark,it seems that the way forward is via magnum engineering as they do all the bits,an i gotta find a tidy cossy box to replace my mt75(4b)

I had a rat 2 litre GL with a 3.5/T5


Was Fun and the sound confused people allthough I did not build this one.


This is the one I built



MT 75 would be a real pain in the butt to fit the Rover V8 as the flywheel is bigger than the bell housing

Ooooo..shiney,i bet the red one surprised a few people
Im in the throws of looking for a T5 ,as im mt75 4wd at the mo, would you happen to know if the T5 will mate to the 4b prop as i want to keep the slipper diff?

[Mark]

I don't know if the 4x4 prop will fit
The T5/Cossie prop should fit your diff though.

Pretty sure the flange on all the sierra diffs are the same.

But if using a T5, you will need a T5 propshaft.

The 4x4 shaft is totally different.

Better look for a prop then
Im in negotiations to buy a 3 door sierra with a full Rv8 conversion that i can strip out and fit in my4b,its running a type 9 box at the mo (easy on the launches ) but i can use it to set everything up and then swap out the box n prop for a T5.
I can see having to get the bell housing re-machined to suit the cos box but im getting the car for the right price so im not too fussed.
