A friend has a 4wd Sierra Cosworth, and is looking to have a little bit of work done to the head.
Nothing major, just some mild porting while the head is off..

Who would come reccomended for such work ?

Thanks, Stevie

 

Karl Norris is the Head Guru

Take a look here

Took mine to BlueSprint.

 

Andy Weston at C.H.D.

 

Unless you going for 400+bhp, i dont see the point on a turbocharged YB.

 

surely its about time that someone gave a detailed (includings pics) account of how to port a cossie head.

even if this gave 70% of the benfit that pros heads' gives it would inspire the enthusiasm that this forum is meant to promote????

 

pgt is this any good to you??

When I lost my cambelt I had the head ported, just 'cos if the head was coming off anyway why not, for only a little more than it was going to cost me anyway.

I've been told that at Stage 3 you don't NEED to do it of course, but that it would idle a little smoother if the head was ported.

 

Karl Norrris did my head but I agree with Steve.

 

In my eyes you either port it or you don't. Don't do half measures. I had mine done by GGR..............

 

and unless he is going to remap the car after the head is fitted,,, dont bother

 

I fully understand your comments. But the guy who owns the car wants it done, as the head is coming off anyway. I did tell him the money would be better spent elsewhere...like on a decent turbocharger.


I'll try and get some prices and see what he says.

 

Opening the ports up on a mild state of tune is a bad idea, you will drop gas speed thats actually useful to have.

Talk to someone like Karl who knows a massive amount about the YB and what head mods give benefits not losses on your friends level of tune.

 

At present, he has only bought greens, 3 bar, -31 and a chip. Not sure what they ( Woodford ) actually claim this will give. Cant see it being that much TBH with std turbo etc.

 

mgith aswell chuck that chip in the bin now, if hes changing the spec of his engine
