What type of performance gains would a turbo 2000 classic see from having a PPP fitted??

 

First check here Home | Subaru (UK) Ltd.
Then do a search on here, There's loads on it.

Simpsons!

 

Supposedly raises the BHP from 215 to around 260, similar gains with torque. I'm assuming MY99/00

However you can do much better with a full de-cat, panel filter, and an ECUTek remap from one of the experts for about the same cost. Should be looking at 270-280 bhp on the standard turbo. Upgrade that to something a little bit bigger for a comfortable 300bhp/300lbft

 

IIRC it's more like 239bhp/259lb-ft on a classic
