Hi guys. I have a stock performance wrx, only fitted a prodrive backbox and green panel filter. I've finished my styling now I'm going to start collecting bits before the map.
I'm plan to get a decat up pipe and a sports cat downpipe (hopefully with the decat pipe joined on as 1 piece).
Now, do I need a 3 port boost solenoid? And a 255 walbro pump? Or is there no point yet?
Cheers

 

The list is endless

Fuel pump
3" exhaust
Plugs
3port not a must but might as well
Good coils
Good actuator
Uprated water hoses from Rad
Induction kit

 

Thanks for a quick reply. I suspected the pump would be a must. However induction kit?! Not good for the car at all until i hit stage 2. ****s up the maf

 

If you mount the induction kit properly to stop it vibrating and don't lube the filter too much they are fine with MAfs
