i run a pretty sick turbo settup, built and sleeved ls/vtec, 60-1, aem ems, aeromotive fuel pump etc etc. heres my question, we just rebuilt my motor after all 4 of my wisecos cracked. block was redone, stuffed with 10:1 je's and my original pauter rods. now when the pistons cracked, they bent slightly bent one fin on the compressor side of the turbo. fast forward, motor is complete to spec, built by a moderator on this board. we let the car idle for an hour on 2 seperate conditions. the car is smoking pretty bad. they tell me its the turbo seals. thing is even though one fin got bent, the turbo still only had 1000 miles on it, any ideas suggestions?

 

anybody have any ideas?

 

Wait, the pistons cracked and bent a compressor fin? Huh...

Well, I'm not sure I understand how the fin got bent but since that thing is spinning at 50,000 rpm or so under load, that bent fin is probably throwing your shaft balance out of whack. That could quickly destroy a turbo. But if you are just idling it that shouldn't matter. Maybe whatever bent the fin bent the turbine shaft or busted a seal or something.
