What paulr33 said.
#But your 3'' xorst will still be ok as long as it is 3'' from the turbo back.
#Hi flow air filter.
#Remapped ecus are allright.But if you have the money get a pfc.
#Maybee a adj fpr.Becuase at high injector duty you will want constant high pressure in teh fuel rail.I was told this by CRD.
#A hi flow rb20 or 25 turbo and you will make over 200rwkw.
Other than that teh stock turbo wont push beyond 180-190rwkw that easily.You do need all of these,though,if you want to get the max! out of your current setup.You need an upgrade on the turbo.
As you would have allready seen though dynos are conservative to say the least.With many saying their car has 200+rwkw on the stock turbo.When i was at CRD my r33 was tuned to 182rwkw stock turbo with a 2.75'' dump,stock cat and 3.5'' xorst from then on.With all the usual other mods.
I hope your not running 14psi in the heat of the day with that tiny intercooler.After the powah look at the suspension if you havent allready.Then take it to the track and thrash it!!
I am at the point now where i can upgrade the turbo and easily make 220rwkw.
HTH...
