I've been reading various threads on PPP for the past year and wondering about taking the plunge - it is a lot of money for the upgrade, after all. So, I paid my £1600 and it's now done, and for anyone else sitting on the fence I can add my opinion.

DO IT.

The basic WRX is a truly smart performer and you may have be sceptical about the notion of making any noticable improvement. But it is definitely sharper.
It is undoubtably quicker off the mark and the tail-off is much higher on the rev count. That's enough on its own, but the real buzz is in mid-range where the surge seems to go on right up to the red line. In fact, you'll soon be into three figures and it's still pushing you in the back.

Anyone who's also had the upgrade will know exactly what I'm referring to. Only the very top super cars in the £100,000+ bracket are now any match, and even they have inferior grip.

 

which car have you got? my?? im thinking about it, my01 wrx feels like it needs something....

 

Have to agree.. had my STI7 for 6 months before having PPP fitted, and it transformed the car. I was definately sceptical before had it done, but now very happy..

 

You buggers........youve got me wishing i had 1600 quid now.

Damn you.

 

Made a huge difference for me, mainly the noise. Beware insurance increase. Use Cross Roads and they'll give you 10% sidc discount.

Def worth it.
