I was driving my 98 RS-T yesterday and when entering the freeway i was speeding up to get with traffic. Before i even got onto the freeway my car was spooling up and the whine of boost was high(was @ 6500rpm). Then all of a sudden i heard a huge PFFFFFFT!! total loss of boost....embarassing. I pulled over and saw the piping directly coming out of the turbo to the piping of the inlet side of the intercooler came loose. It's a 2 1/2 inch C hose that came off from both ends. I took off the airfilter to get to it and re-attached it and put everything back together. HOWEVER now that I try to spool up the turbo it doesn't sound like before and it doesn't kick as much either. feels stock now :(

Do a boost leak test.

Boost leak somewhere.

Nope, you're block's cracked :P





Classic signs of a coupler being blown off. Hell use yours hands and eyes before you do a BLT. You'll probably see where the coupler isn't attached.

turned out to be the delta waste gate...exhaust leak. bolts become undone with too much boost??

Mine would occasionally spit out after several months of use. I ended up using some studs, lock washers, and the highest-temp loctite I could find.
