85.5mm Cometic .030" on an 84mm bore??
 

I see mixed things about using an oversize hg on builds... question is, what's too big?
Not sure how/why i ended up with a 85.5mm bore Cometic for my 84mm bored block.
What neg effects would i see on this turboed block if i use it? Pass or fail?

The only answer is to bore your block to 85.5

Oh man... well, got all disassembled and headed back to machine shop... guess that means i need to buy another set of pistons too. Anyone need some 84mm supertechs?

I'll do this if i get my 2 gps units in the mail tomorrow :fawk: :party:

I *could* get the right gasket - but dont really feel like shelling out another $120ish - ya know?

If the 84mm pistons get sent to me then your gps units can be in overnight mail tomorrow at 8am.

:giggle:
