depending on how much you can do yourself, another route you can look into would be forged pistons, something along the lines of a cometic head gasket with ARP head studs, a mild port and polish job on the head, then you could utilize a basic 50 to 75 shot nitrous set up and be able to get by for a while. 200bhp is a good goal, but honestly, adding 30+hp, to your car, will make a huge difference. 30 doesnt sound like alot, but when your around 100 hp stock, adding 30, a 30% increase, is ALOT.
