platinum plugs run hotter than normal..get the NGK's that everyone recomends..BKRE7-11...i think that is the number...just make sure you get the 7 heat range..thats what i run, and not a sign of detonation on them at 9 lbs. of boost.

second of all, 12 PSI is way too much on stock injectors. the pistons are pretty much able to handle it, but you are not giving them enough fuel, even with the 12:1 FMU. our cars can run 310 CC injectors on the stock ECU, you might wanna look into those if you wanna keep stock internals, otherwise, to run more boost you'll need a Programmable ECU, like there has been discussion about.

Other reasons why people have blown there motors:

using the center screw in the deltagate to controll boost...that ain't what it is there for, get a manual boost controller.

too much boost, not enough fuel, your problem i am guessing...

fuel cut? i wouldn't know about this really...i got a 95.. :)

anyway...i am sure there are other reasons..but basically, if you blew your motor, it is cus, you have too much air, and not enough fuel.
