Turbo Mini Forums

hello
I think looking for people with great knowledge in engine tuning :)

d top pistons standard bores
12G295 head
i want to put an sporty camshaft like 266 or 276 cans

I can not seem to find the information on this type of pistons only on the flat top.

a good ration is 10

please can we help me
thanks for all

when you say d top pistons do you mean dished? (coopers had a d shape that stood up on the piston is the reason i ask)

Could you not measure the 'D' and then calculate the volume?
