im currently doing a clio williams turbo conversion for my R5gtt, just wondering what i should do about pistions, should i get mine machined down? if so by how much and what boost could i run? or should i get forged low comps and what boost could i run before having to change to forged rods?
where can i get a turbo manifolld from? BB tuning do 1 for £300 is there anywhere cheaper?
