blown 2 rear turbos in a row? need some ideas

[te92]

they are just stock turbos but i got a motor that had blown rear turbo, i took my turbo from my blown motor and put it on. once the motor was in started it everything was good and within half hour blew the rear turbo i bought 2 more stock twins and when i got them on blew the rear in 30 min, i pulled once and thats when it blew. if anyone knows anything as to why this is happening please post i have no idea and anything would help.

Blew as in oil seals or turbines? Check for kinked oil and coolant lines to the rear turbo, that's really quick. Other than that the only thing that comes to mind is if it's over boosting. I took out an rb25 turbo in one pull when my boost controller spiked to 1.5 bar. Less than 10 seconds, lol.

More information needed :-

what boost are you running ? how many klm on the turbos including the second ones ? what blew up the last motor they were on ?

What mods are you running ?

who did the turbo swap work ?

blew the hot side turbines off, the boost restricor is out and it hit and held .8 bar. i have no mods the only aftermarket part is yellowjacket coil packs and a big intercooler that came with the car. me my friend and his dad who used to work at midas and has built many cars and deals with his sons supra helped me. the km on the recent turbos was 110xxx and the originals were about the same a little less but still in the 100xxx

there is one coolant line kink that we mostly unkinked but it cant be that because we had a coolant leak after that and it was leaking real good the leak was right off the turbos and as far as i can tell there is no kinks or unusual bends in the oil lines either but thanks for the ideas guys
