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.

I'm living in turkey So sending the piston is a hard job, i will try this after all the solutions are unavailable. Thank you.

maybe this guy could help or point you in a direction http://www.performatek.com/

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.
