OK, think I know where I'm planning to go with my WRX in the long run, will be parts collecting for the next year or so to assemble a long block off the car to be dropped in.

Think I'm going for a 2.35 CDB with forged internals might go Billet crank but unlikely. Will go for a FMIC probably APS with an APS cold air intake. I'll go for one of the MD series turbos, or possibly one of the APS units. Tubular unequal length headers (ceramic coated). 11 or 14mm Head studs etc. Uprated Oil pump and if possible water pump. It's the top of the engine I'm unsure about.

Obviously I have std WRX heads at present and am not sure which way to go as I want to keep the std ecu etc.
My current thinking is to get a set of Newage WRX heads ported and polished with uprated big valves etc, plus a set of fast road Cams.

Other ideas are to fit STi heads from a newage but will this cause issues with the AVCS?

Before anybody says anything yes I will be swapping the gearbox for either a 6 speed or uprated 5 (PPG).
