Lude Posted May 13, 2012 Share Posted May 13, 2012 some of you may remember a few months ago i had an annoying whistle sound from car, which wasnt a boost leak. ( http://www.mkivsupra.net/vbb/showthread.php?264246-boost-whistling-issue-not-boost-leak ) havent been using the car yet this year hardly, now the summers here finally got round to looking at it after a visit to craig/dr jekyl on here, few fellow members suggested possibly turbo failure. whipped off the turbo intake pipe to the 1st turbo, ONE of the fins were damaged, looks like a chip taken out right on the end. didnt take a pic of it as phone died, but was similar to this, (where the one fin has a chip out of) going to remove the 1st turbo and send off to get re-firbished. couple questions: 1) can i just remove the 1st turbo, or do they come off together, then have to split. 2) will i need new oil lines aswell as gaskets? or just new gaskets? ive had all the turbo pipes & heatshiled off before so i know its just a few rusty nuts/studs which need soaking in WD40. any views or tips welcome Quote Link to comment Share on other sites More sharing options...
themodifiedkid Posted May 13, 2012 Share Posted May 13, 2012 I think you can menouver it so the first turbo comes out seperately but i think its better to remove the whole lot. Also its usually advised AFAIK to get them both rebuilt rather than just the 1, as i imagine that you would be getting rebuilt with steel internals. I could be wrong but that was the advise I was given Quote Link to comment Share on other sites More sharing options...
Porky1978 Posted May 13, 2012 Share Posted May 13, 2012 Surely its worth getting both done at the same time just in case the other one suffers similar failure. I'd refurb both for peace of mind. Quote Link to comment Share on other sites More sharing options...
mellonman Posted May 13, 2012 Share Posted May 13, 2012 i think its now time to go update your original thread to aid other people, its easier to just take the pair off then split,you need to replace gaskets only , it would be alot better to get decent second hand set of turbos then to refurb the ones you have imo.

dude Posted May 13, 2012 Share Posted May 13, 2012 I would be finding out whats gone through it !!! Quote Link to comment Share on other sites More sharing options...
Lude Posted May 13, 2012 Author Share Posted May 13, 2012 Yea dude, that damage isit always the sign of an object going through it? Or do they fail over time. I was carefull nothing went in there, or are yhey super super sensative so if any sort of debris would cause such damage.. If the second turbo is fine cant see there being any need to replace?

mellonman Posted May 13, 2012 Share Posted May 13, 2012 I would be finding out whats gone through it !!! remember that is not a pic of his turbo, from what i can guess its the normal compressor fins that are damaged as the turbo is still on the car so wouldnt be able to see the turbine fines Quote Link to comment Share on other sites More sharing options...

Lude Posted May 13, 2012 Author Share Posted May 13, 2012 the pic isnt mine, im showing you the silimar damage i have on mine, its on the 1st set of blades on the 1st turbo (think they are called the inducers) dude, unsure what your last coment is relating to, do you mean then if i have similar damage to the picture ive posted, that it wouldnt always create a whistling sound?

You have posted a pic ofa damaged exhaust wheel when you say you have a damaged compressor wheel, I dont see the point, if you want to know how to remove the turbo just ask or have a look for a guide, i would remove both turbos complete and inspect both, why has some thing gone thru the intake and damaged the blade ???

Lude Posted May 13, 2012 Author Share Posted May 13, 2012 ah right. i was just showing the type of damage i have on mine thats all, but on the compressor wheel not the exhaust one. i had all the turbo pipes and vacuum pipes taken off to clean up and replace, something must have got in there somehow whilst it was exposed (was carefull, obvious not enough) ive seen the guide how to remove the 2 turbos, want to know if i have to follow that procedude to remove them both or can i just remove the 1 turbo. if the second turbo is fine and in good shape, am i ok to leave that one and just replace the 1st turbo?

Are you going to use a 2nd hand turbo? if so just replace No1 if you are refurbing best to do both. Quote Link to comment Share on other sites More sharing options...
Lude Posted May 13, 2012 Author Share Posted May 13, 2012 ok cheers mate. been looking at the epic guide of all time here, http://www.mkivsupra.net/vbb/showthread.php?82952-Blitz-Twin-Turbo-Installation looks asif i would be able to just remove number one turbo relatively easy. well my plan was to just refirb the 1st turbo, if i have to refirb the second turbo too its going to be quite costly. so now youv made me think of a second hand one lol Quote Link to comment Share on other sites More sharing options...
dude Posted May 13, 2012 Share Posted May 13, 2012 Seems mad to just refurb 1, id go for a replacement 2nd hand Quote Link to comment Share on other sites More sharing options...

mellonman Posted May 13, 2012 Share Posted May 13, 2012 looks asif i would be able to just remove number one turbo relatively easy. im pritty sure you wont be able to get to all the bolts to split them if on the car,good luck i think you will need it Quote Link to comment Share on other sites More sharing options...
Dim Sum Posted May 13, 2012 Share Posted May 13, 2012 just wonder, reading back from first page why could re conditioning be worst that a good second hand turbo? Or is it just a opinion? Quote Link to comment Share on other sites More sharing options...
mellonman Posted May 13, 2012 Share Posted May 13, 2012 In My Opinion reconditioned turbos are no why new as reliable as stock or should i say toyotas factory machinery is far more advanced for making and balancing turbos, also i have had hybrids and they are not great at all and cost around £1000 vs £200 for a second hand set Quote Link to comment Share on other sites More sharing options...
Lude Posted May 13, 2012 Author Share Posted May 13, 2012 (edited) In My Opinion reconditioned turbos are no why new as reliable as stock or should i say toyotas factory machinery is far more advanced for making and balancing turbos, also i have had hybrids and they are not great at all and cost around £1000 vs £200 for a second hand set true, but a re-coned turbo, would be better than a broken turbo also think who re-conditions them plays a big part there too im pritty sure you wont be able to get to all the bolts to split them if on the car,good luck i think you will need it hmm looks ok in pictures, will let you know next week!

Ian C Posted May 13, 2012 Share Posted May 13, 2012 I've removed both turbos before without removing the centre section. My advice is... remove them both at once it's infinitely easier! Quote Link to comment Share on other sites More sharing options...
Robzki Posted May 13, 2012 Share Posted May 13, 2012 it would be alot better to get decent second hand set of turbos then to refurb the ones you have imo. Why is this? surely most s/h turbos will be 80k-120kmiles by now. Quote Link to comment Share on other sites More sharing options...
mellonman Posted May 14, 2012 Share Posted May 14, 2012 Why is this? surely most s/h turbos will be 80k-120kmiles by now. As i said here its my opinion,hybrids just dont seem as relieable in my experiance and you could pay for a set that might only last as long as a pair of 120k ones In My Opinion reconditioned turbos are no way near as reliable as stock or should i say toyotas factory machinery is far more advanced for making and balancing turbos, also i have had hybrids and they are not great at all and cost around £1000 vs £200 for a second hand set my stage 3 hybrids needed a ecu bigger injectors and lots of other bits they cost £1,200 and only lasted for 1 week over a year and covered about 5k there dimise was a boost spike of 1.5 but should of coped with that as they had a spec of 1.6,dont get me wrong if you run 1.2 on them they might last for ages and not need other mods but mine where set to 1.3 daily and 1.4 for special times.
