Mick5994 Posted July 26, 2013 Share Posted July 26, 2013 I know that the WRX STI got a upgrade to 320 not long ago but as I'm doing some digging into the 2nd hand market I'm seeing a few cars with a 340R Prodrive option. Does anyone know what has been upgraded on these models or is it simply a re-map to take it to 340 Bhp? Again any help is appreciated as I dont have much knowledge about Subaru's as I've always been a Ford and BMW owner in the past. Quote Link to comment Share on other sites More sharing options...
Jay762 Posted July 29, 2013 Share Posted July 29, 2013 It varies slightly depending on the model year but overall it tends to be a map and stainless steel prodrive backbox but it can also include a fuel pump, filter and induction tube fitted between the standard filter box and manifold this provides some information on the upgrade if purchased as an extra from a dealer http://www.subarupartsstore.co.uk/category/Performance_Parts/Prodrive_Performance_Packs,b.html Quote Link to comment Share on other sites More sharing options...
