You may be able to get by with a SAFC, but in all honesty you're probably better off to save your money and wait to buy a Power FC when you can afford one. With those mods listed you should be able to get close to 200 rwkw with a Power FC, but would struggle to get those numbers with a SAFC, because you cannot adjust the timing. Later down the track when you want to put a larger turbo or injectors in, the Power FC will cope easily - where as, you'd have to chuck the SAFC in the bin.
I find having the hand controller is an invaluable tool also, as it will display peak values on Engine knock, RPM, injector duty, water temp, etc. So at any time you can have a quick glance to make sure the engine in operating within limits.
I realise a Power FC is $1000 more, however the extra tuneability/features are well worth it.
