CA18ET - Race engine build

[Raz987]

Hi guys,
Well, my season of racing in the SS1 is nearly over and I'm looking to next year already
I want to rebuild my engine over the winter. The engine itself has been reliable (shame about the rest of the car ) but I want to give it a freshen up and add some power/torque while I'm at it.
It was dyno'd last week at 160bhp/180lbft @ 10.5psi. Current spec:
K&N filter
T25G Turbo
Lancia Delta intercooler, mounted facing down with scoop under car
2 1/2" side-exit single-box exhaust

My target figure is 240bhp, but the main things I'm after are a strong, smooth torque curve and reliability, within a reasonable budget (this is club racing, after all!).
After conferring with CNHSS1 we've drawn up a spec list that I'm happy with:
New bearings, oil pump, gaskets etc.
s13 pistons & rods
SAFC Neo
S13 injectors
Adj fuel press reg
Autosprint cam
Custom plenum welded to standard intake runners
S13 throttle body
More efficient intercooler setup

That's about it. Can anybody think of anything we've missed or that I should I consider?
Cheers, Raz
