Question Crank and Conrod question

Would a crank and conrods from an Sti7 engine be considered an upgrade over an MY95/96 WRX standard setup?.

Or would they not be compatible?.

Thanks.

BB that's not strictly true, phase 1 blocks can be machined to take the phase 2 crank if you really want. But it's not really worth it on anything other than an EJ20T or E22T closed deck block.

The rods of an Sti 7 are better made and a stronger design than the rods fitted to any classic shape engine, and can be used with an earlier phase 2 crank. The Sti 7 crank however is identical to that used in classic phase 2 engines, an improoved crank design came in with the Sti 9.
