We've proven with the St185 GT4 we have that the 3SGTE is (unless mega-dollar specced), is a wart of an engine. The things have more oil control issues than the king of oil control issues, the RB26.
A willing engine, but pale beside the might of a 200,000klm RB20. The 3S doesn't rev, doesn't go, and in an MR2, is just plain slow due to appalling untrustworthy handling.
Can you tell I'm a fan?
At least the St185 GT4 doesn't try to kill you, but neither is it fast, as even our lightened and stripped one verifies, they really are a heavy pig of a thing. AND, it looks like a Corgi lying on its back.
