That's when things get interesting.
Our Version 8 is the 2002 STi, the first bug eye STi we got.
But not the first bug eye WRX.
Our current 2004 is a Version 10.
All OZ spec STi's had Forged pistons.
Some better than others.
We never got the first bug eye STi, which was the Version 7, but I beleive it has the same internals as the Ver 8.
