can anyone tell me what these pistons i have are ???
was given them by a friend of a friend and have no idea what they were from other than a cosworth??
part no on them is 90p44w24?? also on crown has sp0,05 and 91.775 ???

i thought maybe that meant they were + 5 size pistons with a size of 91.775 but that seems big for a cosworth am i right or wrong

also if they are 91.775 what displacement would that make out of curiosity???
any info would be great am clueless and tried looking on mahle and cosworth,s site but no luck???

just wanted some info on them ie what for 2wd or 4wd and what size bore ??? +5 or +10 etc

 

while its slightly like it dont cosworth pistons have mahle on the under side??

 

yes they are mahle pistons as is stamped underneath nr the gudgeon pin
anyone ????

 

Displacement would be 2037cc on a std stroked YB
