As title, Are Focus RS, St170 etc all the same gasket from ford, and how thick will it be to work out the CR for some pistons?

Cheers

 

The Focus RS headgasket 0.6mm
The Focus ST headgasket 1mm

St170 turbo but i have a few things to address first i think lol. It was an accident off flebay! best offer is dangerous!

 

Just use one of my thick 2mm head gaskets, a nice inlet (from Sitech)and smallish ball raced turbo on a rst manifold running on Gotech


Job Done a very drivable 300bhp

with standard internals and a 2mm head gasket standard heaad etc what kind of CR will it see?

I haven't got a huge budget so am trying to use as much of my old things as i can for the time being.

 

CR 8.5

 

and at 8.5 with some gotech management to control things you think the standard bottom end is fine with all that? i only have a baby T3 at the min but will look at bigger turbo's at a later date.

20 PSI through all the with correct fuelling etc would be safe enough ?

Cheers
