On no Gaz, not another one :(

 

Out of interest did you every have antilag/2step running with this turbo installed? It seemed to be the cause on all but one of the other failures...

when it was originaly mapped, he put a rev limiter on a switch at 4k, but something was wrong as it was just popping and banging all the time, when lifting off throttle, i think that was the problem, it was very embarising just going down the shops scaring everyone and me

This is the journal bearing or the BB R version? I know Jay lunched a DBB, but everyone elses have been the journal bearing.

 

no not the dbb

Looks like a diesel turbo to me. Not designed for the heat of a petrol engine, let alone a modded one. Test book heat damage, the tips get near white hot and centrifuge off molten material. If they were made of a suitable material for the temps and speed involved they wouldn't. I bet it's not a genuine Garrett?

i would agree on 3 counts, 1st heat damage, 2nd non genuine, and the 3rd count is the ex trader that supplied and fitted it:rolleyes:

 

have you been using 2 step launch control?

 

rev limiter and bad mapping mate

Yep thats the damage i was refering to :( . I hope the one i have fitted doesnt go the same way, however that came from precision and has GARRETT in big letters on the coldside and a Garrett badge on the actual cartride...so i should be ok ;) i hope!

 

Gaz, you shouldnt of chucked the whole lot though, could have sold the coldside and hotside on here or ebay! Maybe even the whole cartridge to someone who who fancies a project jet engine or something! (i read on here somewhere that someone did it :search: )
