Opel Club Cape Town

was thinkin of buyin forged pistons and maybe rods for my turbo setup
as it is now im using the standard rods and ks pistons that i machined 2mm off the crown to lower the cr and coated.

at the moment im running 0.3bar cause it not tuned yet but want to run at least 1bar.

here is what i got
160ie astra
head flowed
270deg cam made by mastercams for a turbo setup
350cc injectors
dictator
copper clutch and double diaphram pressure plate
lightend flywheel
ihi rhi5 ceramic turbo
38mm wastgate

so should i fork out for forged pistons and rods?
and how much and where do i buy them and rememder money IS an issue lol
