what kinda horsepower should my car make with this setup.what can i do to improve it?

[lilbnort93]

Okay so heres my setup.
s13 Redtop sr20det
-cometic metal head gasket
-arp headstuds
-DEACTHWORK 550CC side feed INJECTORS
-Z32 MAF
-rb20 oem fpr
-ROM TUNED ECU
-isis intake manifold
-tubular exuast manifold
-isis rs3871 w hks adjustable wasgate set at 18lbs with a forge manual bc
-isis braided turbo lines
-fmic
-freddy bov

looking for an estimated power level on current 18lbs of boost and if the power level on 25lbs sounds about right for what it supposedly made

was told that it made 363hp and 290ft lbs on 25psi

in my opinion that seems kinda low for the boost level.
what could be restricting me from breaking 400? maybe cams? would i need a bigger turbo? i know im gonna need something bigger than 550cc's.

Just one bottle in the fuel tank... Should add around 20whp.

+1 for you sir :bigok:

Get engine management and a wideband so it can be tuned properly.

+2. Bigger turbo, injectors and fuel pump and an Enthalpy tune

Go for some decent cams. With a turbo that size you want your engine to breathe :D

if you're wanting to push 400+, i would also do the bottom end.
