i'm not going to reply to your remarks any longer. as far as i can tell, the engine in the easy street wrx started from a wrx engine, not the sti engine. how does this relate to anything you have to say? it's absolutely pointless to continue this discussion if you're not going to bring anything to the table.Phil P said:In 2.5 or 2.7 displacement. Modified obviously, it's a drag racer. Sleeved block etc etc etc. If your looking for a stock "STi" engine in this class of drag racer, won't happen. The point is the block/engine family are all swappable in components. Cranks, heads (SOHC, DOHC), rods,flywheels etc etc. Proving long time durability. Hang on to the thought the STi is untested.
