I really don't know much about the foresters, but what power difference are we talking between a standard turbo Forester compared to the JDM version, not including the STI.

Thanks

 

Depends what version SF5, SG5, SG9, SH you are talking about.

The SF5 and SG5 models for the UK were detuned with softer cams
The JDM versions came with the same engine/power as the equivalent JDM WRX.

 

The JDM SG9 Sport Cross is the 2.0 AVCS equipped car. Far better spec list with HID etc as standard. 250 PS is standard.

 

Ah yes should of opened with that

Been looking at pre 2000 models and 2000-2005 models. I know some Impreza WRX's classic shape came in 260bhp and 280bhp. Of course more choice with 2000-2005 models.

 

SF5 upto MY02
SG5 MY03 to MY05
SG9 MY05 and onwards with facelift MY06 to MY07

 

Ok nice. Any info on the SF5? UK and JDM models. BHP difference etc

 

UK (MY01 figures) 174 BHP @5600rpm / 181 Ftlb (25 Kgm) @3200rpm

JDM S/Tb 235 BHP (240Ps) @ 6000rpm / 228 ftlb (31.5 Kgm) @4000rpm

 

Wow really. Gutted i contacted the guy but hes now sold it.

 

SF5 STi's are 280 bhp but not many good manuals knocking about.

 

Can anyone tell me how much power will a forester sti jdm SG9 engine take before it needs to be forged? Is 450bhp to much to hope for?

 

Probably would look at uprating, but the box should be OK as it is the 6 speed. The SG9 Inter Cooler is also the same size as a standard Blob/Bugeye WRX not an equivalent newage STi.

My SG9 STi had the Litchfield 330/330 set up with a Zero Sport CAIK and hard pipe. It had face rearranging torque being the 2.5 lump, proper quick when needed.
