found out it was just a pulley wobbling because the belt tension was not to spec, car sounds like a dream, but as soon as i fixed the belt issue the clutch slave cylinder blew the fuck up lolz

oh boy, didn't even think of that. The guy I bought it from told me he installed a new clutch so he could have installed the flywheel wrong and F*CKED it up! Considering when he sold the car it had a "blown strut" so I take it home and when cleaning out the trunk I find 4 little pieces of springs that had been cut, NO cat...or any flanges on the exhaust everything was cut and welded together.....he denied he had anything to do with either things..but after I gave him $$ for the car him and his buddy lugged out a huge tig welder to weld an intercooler on his friend's Evo....so I can only wonder how much shit is wrong w/ this s13..I hope you are wrong about the flywheel but right now I am fearing the worst. Thanks for the suggestion though. I will def look at it once I get this motor pulled.

i dont want to scare u but have u or do u kno much bout ur trans...the reason being is that my car made a similar noise,and it turned out to be that my flywheel was breakin apart...i never checked it until one day it just shut down on me and wouldnt turn back on or over...after checkin normal things(starter,alternator,ignition,battery)it was time to go inside we took apart my trans. and my flywheel was completley broke in half
