The short version of the motor story:

52,000+ miles +
16psi +
repeated pulls to 7200rpm in anger +
hard lateral G's (potentially reducing oil pressure, although Mr. Shields disagrees) +
known lean condition on cylinder #3 due to stock fuel rails
=
probable detonation on #3 which damaged the bearing and left me w/ rod-knock

Since the cost of inspecting and repairing whatever's wrong w/ the EJ20 is probably more than just replacing the short-block, I'm not going to even bother to crack the motor. The guys at the shop are just going to install an EJ257 long block on the car. Afterall, if it breaks, and you don't make it better, it's just gonna break again.

So... once they're done (probably late next week) I should have a 2.5L STi motor w/ the GT30-10. We're also probably going to do the TGV deletes, and I'm leaning towards a small front mount, since the GT30-10 spools so fast on that block I can get away with some increased lag.
