My car is putting out around 450 on speed density with a grime speed 3 port at 27 psi. What can I do to see around 600. I'm trying to avoid the hole e85 thing too. Maybe a bigger turbo.

Current mods are
AMS 30r kit
Tbe
272 bc cams
2.3 stroker
1000cc injectors
deatschwerks 300 fuel pump
Turbo xs intercooler
Ets short route ic piping
Ets ported intake manifold
70mm Full blown Throttle body
Exedy twin
Busher Trans
Spooling up cop kit

 

Get the head ported if not done so already, bigger turbo (will add lag), you will need a single walbro 450 or a double pumper setup with bigger injectors. You will have to run either E85, Meth injection (Not recommended), or C16.

I agree with pal,your going to need larger turbo, double pumper, better cams being BC cams are crap, larger injectors, better intercooler preferably a Garrett core thats about it. Oh and a good tune.

 

e85 ftw

 

IIRC, GSC S2's are 276/276? That would be a solid upgrade, IMO.
As stated above, fuel system needs some freshening up. I feel your IC core is fine for your power goals right now. But that's all personal preference at this point.
On a 2.3L, I can see a turbo in the 6266 GEN. 2 class/range being around the ballpark of what you want without too bad of a WAIT:BOOST ratio on 93 oct. (I'm assuming that's the fuel most commonly available to you)

 

Gsc s2 cams are advertised as 274s not 276s.

 

Thank you for the correction! I was somewhat unsure on the exact digit, but I remembered it was claimed to be higher than a 272 haha.

 

The original S2's were 272's, the most recent ones are 274

 

Not a prob glad i could give you a helping hand on some info
