What county are you in ?

As I might be interested in a few bits if it gets broken and not bought whole to fit a new engine.

If it was mapped to 392 hp , just about any standard classic engine/ drive train would spit it's dummy out at that level of tune [emoji6]

v3 sti from the title so would be ok as long as a bit of mechanical sympathy given, gearbox would be on borrowed time though

Think the Add says my 93 (v1)[emoji6]

Personally I'm unsure if it's a sti as the early v1 sti's all had build plaques on the drivers side turret (can't see one in the pics) .I wasn't going to say anything but seeing as it's being broken and the engines fubar it won't affect the value of parts to the op [emoji6]

although all classic sti's have forged pistons the early v1 & v2 have the weaker "dog bone " shape piston chambers which are prone to cracking and splitting piston rings when pushed or unmapped

Even from v3 sti onwards most classic heads will start to "lift" and rods are at their limit at 380 hp hence why standard head bolts and gaskets are normally binned for uprated ones if aiming for close to 400hp
