what forged pistons brand

[filh]

Thanks for that info Totta Crolla .

But here in Belgium , smallports are rare to find .I bought a 7 seven ribs block some time ago and much to my surprise , all internals were just like a 3ribs bigport .
But of course I know a real smallport is stronger as internals are a little bigger and heavier.
But I can't explain why pistons are so weak in bigport. That's why I'll buy forged ones.
In my mind , it's impossibke to buy a stock smallport and fix it in my rallycar.
It must be opened for rebuilding Most of these engines are 20 years old and are sport engines.
Im just busy with a bigport head , cutting some angles in ports and having some polishing inside .
