I'd say go to http://www.fd3s.net and learn how to do a compression test, then come back with the numbers. good compression is 80-100 on all 6 faces. If you don't want to/have the time to do a compression test, you can also pull the feul pump relay and pull the spark plugs, then slowly crank the motor and listen. if you get stree strong wooshes, then your seals are fine, if you get 1 strong woosh and 2 soft wooshes, then you have a blown apex seal.

get a wideband, an aftermarket regulator, and a fuel pressure gauge (and the Supra pump if you don't already have it)...mandatory upgrades on these cars

the next best thing to a compression test: look at the vacuum at idle on your boost gauge. if you're pulling like 10 inches of mercury at 900ish rpm on a stock motor, and the gauge is oscillating back and forth (like from 9 inches to 10 inches to 9 inches etc) then you probably have a cracked seal and a blown motor.
