SR20 Exhaust Leak No Boost

[revsx]

So awhile back I was at a track day and went off track and hit a tire wall head on and then I could hear an exhaust leak, but thought I had scraped a hole in my exhaust. Upon driving around the track I was only building about 3psi of boost and the needle wasn't very steady. When I got the car home above the turbo on the hood it was really hot. After I let it cool down I realized the turbo was loose on 2 out of 4 of the bolts. I haven't gotten the turbo off yet as I need a different wrench to get the line off the back of the turbo or block (They seem equally as stupid.), but after explaining the circumstances what are the chances the manifold/turbo gasket is blown?

It would be a good idea to change the flange gasket; but it may still be okay. Those 4 nuts are notorious for coming loose- which is why Nissan sells OEM T25/T28 locking plates to keep them in place: Nissan Genuine OEM T25 T28 Turbo Turbine Locking Tab (http://www.frsport.com/Nissan-Genuine-OEM-T25-T28-Turbo-Turbine-Locking-Tab_p_8123.html)

Thanks cause I ordered coilovers and that gave me the motivation to get the car back running properly and I never thought about the gasket being blown from the loose turbo nuts, but hopefully it isn't and I'll get to drive for the first time in a few months.

It's a good idea just to replace all of those factory gaskets while you're at it.
