just bought a set for £150

 

i see these but didnt think they are forge

 

pass, spoke to bloke and seemed to know his stuff plus his feedback is cool

 

Standard +0.5 RST cast pistons.

 

thats what i thought, so these are no good for a low comp bottom end (am i right)???

 

Low comp is made from the pistons. The bottom end doesn't matter

 

it is the correct part number for OE +0.5mm RST pistons. as to whether standard pistons are cast or forged????
Mahle call it "Autothermatik/Hydrothermatik® piston" rather than "Forged" as they describe the cossie ones..

 

well i thought you needed forged pistons for low comp as they are better for the job in hand

 

I thought standard RS ones are mahle forged ones?

 

no i thought they were cast

 

Mahle make standered Ford RST pistons
But there around a £100 each

Nothing specail about them but well worth £150

 

You do, but thought you meant rods/crankshaft

 

mahle make std cast for xr3,2,2i,etc etc at 9.5:1, and rst/cossie forge 8.0-8.3:1.

do you know wot they were?

 

they ones from ebay are 8.2:1
