Hey all, so from what I've read in old posts I'm pretty confident I blew one or both of the stock turbo exhaust wheels last night. Car was on boost at WOT, then I shifted (around 6500/7000) heard a loud noise car juddered and rattled and no more boost. What I wasn't able to find searching and has me worried were some of the other symptoms I had. I don't remember if I let off right when it happened or not, but shortly after the pop I pulled up to a red light. It made some horrible rattles noises, sounded almost like my front pipe came off, idled horribly going from too low to too high, but then rattles went away and it settled down. I didn't notice any smoke out the back but to be honest wasn't looking back there. After the engine settled down there was still a spiny rattle noise that's particularly noticeable when near the exhaust tip, idles normally, and drives normally off boost. I limped it the 2 miles home and it drove ok but couldn't build up boost. Oil pressure, oil temp, and water temp all remained normal; even when the engine was acting up. Haven't started it up since.
For reference I have a decat pipe, tomei equal length downpipes, and a cat back muffler. Rest of the car is stock. I noticed the day of that the car was making a bit more boost than usual but I never turned it up myself and had been running stock boost until then.
Planning to take off the down pipe, endo-scope up the rear of the turbos, compression test, and endo-scope through the sparkplugs for any noticeable damage. If I don't find anything doing that I'll start checking intake/intercooler piping and get the stuff for a leak-down test. Again, pretty sure this is a blown stock turbo exhaust wheel, but I'm wondering if anyone has any other ideas for what to check and if my symptoms indicate something catastrophic. Should I start budgeting for a new/rebuilt short block?
Also side question, assuming the engine isn't boned, can I run -5's on stock boost with a stock ECU/fuel system? Not sure I have the funds to do everything at once and was hoping to get it back on the road this summer.
