Need Help rebuilding a 1.8 Turbo engine - Searching for Forg

Hi,
I'm going to rebuild my 1990 Alfa 75 Turbo's engine.
After engine rebuilding, i will use megasquirt as a ems system, garrett gt2876 as a turbo with 750 cc injectors. So i will expect at least 300-350 hp from the car.
But, as you know this is an old car, i cannot find competition parts.
For example when i rebuilt my subaru impreza's engine, i bought pistons from wiseco, connecting rods from eagle, sleeves , head gaskets and oil pump from cosworth and a twin plate clutch kit from exedy. This was very easy.
So... How can i find forged pistons, forged rods , strong sleeves and a special head gasket (like cometic or cosworth) and a twin plate or bronze clutch kit ?
If anybody can help me, i will be appreciated.
Thank you all.

Cometic will make you a head gasket to suit. They will need a head gasket for your engine and to know how thick you want the gasket. They are online.

I'm living in Turkey, cometic is based in Usa, so i cannot send my old gasket to them. Gasket is not a big deal for now, because i cannot find forged pistons.
Maybe Wiseco, CP or Arias can produce pistons for me , but the problem is, i only know the bore and stroke (80x88.5) , they need this information :
piston pin measurement,piston compression height, piston dome/dish volume, valve place depth. Anybody knows these values?

Send them a piston as a sample. That way they can make the new pistons without guessing.

There is no post office in Turkey?
I sent my piston to the US from Sweden. Still waiting for the pistons though.

Talk to Greg Gordon (
www.hiperformancestore.com). Give him specs for the pistons and he can have Venolia make pistons for you. I can't say more, so it's best if you contact him. He MAY have rods for the 4-cyl as well.
