Difference between newage STi and WRX
As the tittle says does anyone know the difference between a WRX and STi?, all ive come up with so far is
6pot brakes on the front
550cc injectors
bigger turbo
bigger TMIC
better suspension
6 speed gearbox
and cosmetics
Have i missed anything? such as engine internals? headers, cams ? is it the same ecu with just a different map?
Reason i ask is i brought a 53 WRX PPP back in march and am after a bit more power, with about 1-2k to spend.
Thanks

I was under the impression that the engine internals, the engines themselves where the same. Only difference being in the turbo, intercooler and injectors.
Also would a remap unlock many more ponies? with PPP its already at 265 ish, would a remap unlock much more without changing the turbo?
Thanks for the information so far guys, liking the idea of improving the handling and brakes. However if the difference between a WRX and STi is that big maybe id be better off selling up and buying a STi

Don't know about the later ones but bugeye differences are:
STi - semi closed deck block
WRX - open deck block
STi - forged piston (I think !)
WRX - cast pistons
AFAIK they use the same crank and rods
STi - VF30
WRX - TD04
STi - 550cc pink injectors
WRX - 440cc blue injectors
STi has AVCS (variable valve timing) heads, different cams and valves.
