I have a gt28r s15 speck r turbo that the oil drain hose kinked. It leaked oil threw the seals blowing threw to my exhaust. I changed to another gt28r. My question is ARE THE SEALS BLOWN OUT OR WILL IT SEAL NOW THAT THE OIL DRAIN IS UN-KINKED? I was told it will seal after un kinking the drain line. Let me know what you guys think!

GT28R is ball bearing right? You're f'ed if it is because they aren't rebuildable. You can just replace the CHRA (center cartridge), they can't be rebuilt. Blown seals don't usually repair themselves on their own either.

It is BB. Thats what I thought. Thats also why I got a new 1! Jason from xat told me when the line kinked the pressure made the oil seep past the seals and If I had un kinked the oil drain It probly would seal again with out the pressure bilding up past 80psi. Is there a way to test the seals around the oil pump pressure to see if it will seal? If not, If I port and pollish the both of the turbo housings in the gt28r(s15 speck r duel ball barring) will it flow past 320whp? Boost past 17.5 psi?

If it smokes the seals are effed. Turbine efficiency has very little to do with what happens after the air is compressed. It might spool a bit better from the port but it won't gain any efficiency.

2 people say its toast. after only 2000 miles! Its sucks the turbo and the CHRA are the same price! You would think the CHRA would be cheeper! I just put my MBC on and its making 12psi @3000rpm then its breaking up poping and cutting out @4000 rpm. I dident mean to but it hit 16psi @ 5500rpm! WOW THE TURBO SPOLLING SOUND @12+ psi IS GREAT! MBC is comming off untill coilovers wideband 550cc injectors and a tune umong other things. That higher boost spooling sound sold me WOW!!!
