Hi everybody, I bought Fiat Coupe 2.0 16V non turbo with the engine disassembled. Now I repair it. New piston goes for a block on 0.7 mm. Is it OK or not? Please help me. Excuse me for my English.

That should not be a problem - head gaskets come in different thickness you can get unto 1.8mm I think.
Are you using standard camshafts ? You should make sure there is clearance between the valves and the piston by doing a dry build, an calculate the compression ratio because that will may be higher.
who made the pistons ?

New pistons - original +0,4. Before there were pistons Croma 8V, they were level with the block.

I'll have a Coupe 16V N/A engine in the next couple of weeks. All I need from it is the inlet cam' for my turbo you are welcome to the rest of it if you cover shipping.
