I got a map at Alan Jeffery which was referred to as a stage 1 tune. He got it to 275bhp. I asked what my next options were and got told a stage 2. This would include a t16 turbo, injectors, fuel pump, up pipe, turbo back exhaust and another map. This would get me around 330bhp and cost 2500. Is this correct. R there other options? Does a turbo have to cost a grand? I know nothing about imprezas and have never owned a turbo car. It seems like I can source the parts myself and they all just bolt on then pay for the map at the end

Hi every1. I've got a 2004 wrx that I want to stage 2 tune. Tried reading up on what upgrades I need but there is so much conflicting info on so many different threads. The car came with an sti tmic and a cat back stainless exhaust and ive got a stage 1 map last month. Ive been looking online at various parts but prices vary massively for what appears to be very similar parts. Any advice would be appreciated.
