Just upgarded 2000 wrx with 2.5l STI block from the US. - Added forged pistons and Rods. Using vf34 and Autronics ECU, 18PSI boost. Fuel - BP 98 RON and original WRX (not STi) heads and cams.

185KW at wheels, 520NM torque. (Hoping original 5 speed box hangs in there.

Using Whiteline Goup 4 Coilovers to get the power to the ground.

Awsome day at the Track last Sunday - only one tricked up 02 STI (ECUTEK) came close.

Thanks to the US for having such weak fuel and therefore need for the 2.5L - now we can finally import the 2.5l to Oz. (Now becoming a very common upgrade in OZ)

BTW - Original unused pistons and rods out of the US STi 2.5l block for sale.

 

rexquisit,
where did you source your short motor from? I am now living in Switzerland (ex Aussie) and my 2002 Sti is about to drop a big end. I am thinking about the 2.5 block if I can find a shipper who will send one to me.
