Well I've got a 250 engine in my 200, nearly! And the meg boys are pushing 360bhp from these now? Why forge a 225 lump? Just buy the 250 engine that already has forged pistons in it from the factory?
As for the 200 box, well to my knowledge the highest bhp clio on here, shakeys is working just fine? I only spoke to him about it last night?
So when not use the lighter box with the closer ratios? Better for performance all round?
