Hi all.

As I'm rebuilding my cosworth engine (sierra 2wd), I bought a new 200 block and a "thick" 4x4 cilinderhead.

Now I still have my 2wd exhaust manifold, turbo and turbodamper,
but the 4x4 cilinderhead has no "ears" to attach the turbodamper, because the 4x4 didn't have a turbodamper anymore.

Does someone have experience with this "conversion", so I can still use my "2wd" t03 turbo? (And possibly the exhaust manifold to)

Thanks for the reactions.

 

As far as i underestand it to use the 2wd manifold with the 4x4 head you have to use a special turbo damper which i believe spec-r can supply

 

Does this mean that with the Spec-R or Bailey turbodamper, I can still use my 2wd exhaust AND standard t03 turbo (and in the future T34,T35 of T38 turbo)?

If so, do I need to make sure other things will be done, because my plan is to go to just under 400bhp.

 

you will find no need for turbo damper at lower power,but as said above bailey do a kit for a 4x4 head

the turbo damper is nothing to do with power - it's to do with vibration of the manifold. if you use a 2wd manifold, you must use a damper of some sort.

you have 2 options:

1) there is a fancy damper from one of the makers of shiny bits (could be spec R) that has a tripod looking thing that bolts on to the top of the rocker cover.

2) mike rainbird sells a bracket to bolt on to 4x4 head sto allow the use of a std damper. see this thread:

i will be going for option 2, as my project car has nowhere for the damper to fit to (i'm not sure if it's a 4x4 head, or if some twat just cut it off).
