the hosing itself dosent seem to be damaged just a little pitted (nothing near as bad as the plate behind the exaust wheel)

the only thing i can think my have caused its somthing blown out the exaust (maybe bits of valve or piston ring?) as there is only a minimal amount of play in the shaft. anyone agree or dissagree?

secondly would it be posible to have another t28 exaust wheel put on and balanced etc without machining the housing or does each housing get machined to each individual wheel?

Wow, this has been chopped up a bit dude... have you been running this turbo? If so, is the boost affected much by the damage?

It should be possible to have just another wheel put on, but it will require a turbo rebuild anyway.. erm, is your car running lean?

[cri_ag]

nah i havent run it but i planned to. friend of a friend got it for me for nothing, was sitting in a corner of an import yard, guess i know why now!

[Andrew162]

hmmm, so are you going to have it rebuilt or go for another turbo in decent nick?

[cri_ag]

well im debating that one now, stick with the turbo that i know what is wrong with or have a punt on another. i had a quote to do bearings and seals for $400 so i was hoping they could throw another exaust wheel on while it was apart. if that is possible and comes in for a reasonable price thats the way ill go i think, seeing it dident cost me anything i might be better of.

[Andrew162]

Well good luck with it whichever way you go... you already have it, and it won't cost that much to fix it I guess...

If it costs you $400 all up for a turbo + a reco, i'd say thats a decent deal

[cri_ag]

Yep thats my thinking as well reco it is!
