Hi all,

 

Currently starting a GTM Coupe rebuild with what I believe is a metro 1275 engine. (build thread coming soon) 

 

Just having a look at some of the components and wondered if the pistons in are standard, can't seem to find the part numbers online.

 

I have three: 20142 G2 H22 

and one:       20142 G2 H21

 

All measuring between 70.45mm and 70.55mm at the skirt 

 

any help is appreciated!

 

cheers

Is it out of an Allegro block?

Thank you!

 

According to the Guessworks calculator my engine number comes out as Metro Economy

 

Did they just use the same pistons in the Turbo as they did in the Economy then?
