Loud Boom!
Ok I was driving tonight and another turbo'd car pulls up next to me, so we were screwing around and I misshifted going about 65 I went from 5th to 2nd and there was some sort loud boom that came from my car so we pulled off in a lot and checked it out. Nothing seemed to be wrong. So I left and meet up with a friend and while I was in my car waiting for him the check engine light came on and it started idleing real funny any ideas? It still boost so I don't think its any hoses or anything like that. Maybe I bent the valves?!

Re: Loud Boom! (BVM)
Check your cam timing first. The others may be right, but don't give up hope yet. When you accelerate the engine like that, the chance of skipping a tooth or ? is very possible. You will probably find that the the cam(s) are retarded.

Yes!!, do a compression test. But realize that low numbers from a static comp test *can* be due to cam timing problems. Don't buy an engine until you check the cam timing.

65mph? thats just taking 2nd gear a few mph past redline... its not as bad as doing 80+ and downing to 2nd gear. i think i saw some pics of a guy w/ a rsx type s who did that.

Re: Loud Boom! (sushibug)
good call. I've gone from 5th to 2nd doing about 50-55...it's called down-shifting...makes the car accelerate... 65 probably didn't even bring the engine to 8000...so, it's probably not that bad, though the CEL is a scarey thing

Check your plugs, you could have blown off the tip. Its the engine backfiring in the combustion chamber. Its either that or you blew your headgasket.

Update
Well $1300 later its all fixed.
The valves were totally screwed. Place I took it to said they were the worst they had seen.
But I got
-Skunk2 low compression valves
-Crower retainers and springs
-ARP head studs
-New head gasket
P.S. be carful when you shift
