if you mean how much power...then it depends on how much you want to spend but basics like exhaust,filter and ecu will give 7-12bhp (is that 5-10ps?) for around £800-1000 then its head and cam work and then supercharge time!! but you wont get lots of power even with these mod's!!

has the pistons and head being done? what size intercoller do you have? what turbo are you running? and what psi are you currently running? and finally is the head gasket standard
as increasing the psi you raise the compression which can blow gaskets and melt pistons fast!! and by increasing the psi you need better cooling from the intercooler and you need to make sure the turbo can take it too!!

I once ran a lwb citroen tdi van with a broken actuator and it was stuck at 26-28psi...it was crazy fast but the engine gave up very shortly after (serves my old boss for not paying to get it fixed!!)

thats great...but on that note its a n/a car no turbo and nothing has been changed from stock
the intercooler can hold up to 20 psi and the piping as well
the gasket is a rubber gasket not stock but nothing special and the pistons have not been changed
the turbo can push 13 psi or more but dare not to push harder

well without lowering compression with better pistons and a flowed head i would run 6-8psi to be safe (I guess thats what you have now?) anymore and you will need to look at upgrades!!

nope i have none, zero, Nada, big fat 0, on the psi's right now
but 6-8 would be awesome it would still atomize the fuel better than it is now and i could remap and get better fuel economy cool youve been alot of help bradley  :laugh:
