Jeff's Turbocharger Rebuild Thread - Jeff - 10-10-2005 I have decided to rebuild my turbo myself instead of paying someone $300 to do it for me. I have called every "trucking service" place here locally to try to get my "turbine shaft and wheels balanced" and I have had 15-20 rednecks laughing at me saying "why the heck would you need to do that!?" What should I do here? One place was real bad I could here the whole office laughing and the woman tells the service guy who is coming to answer the call "thats what he said, really, balance the turbocharger HAHAHA!!" So yeah, this sucks. I have the rebuild kit coming and the only piece of the puzzle missing is the balancing of the wheelsI forgot to mark them when I took them out. Ill post some pics of the tore down turbo when I get back from lunch. Anyone know of a place who wont laugh? - Mike - 10-10-2005 didn't silvia tell you to send it away? - Jeff - 10-10-2005 Well...then it turned into "lets at least take it apart and see what crapped out." I explained to her that doing that would likely ruin the chance to send it away because TU dosn't like to do them after they have already been pulled apart. So we decided that we would get a kit and do it ourselves because it wasn't hard to take apart. Anyone ever done this before? I was wondering if it might be good to take a brake-cal piston hone to the bearing surfaces before I put the new ones in. - PDenbigh - 10-10-2005 Ignore the rednecks. A turbo spins at 60,000+ rpm. F=MV, M is small, but V is huge. Based on that, I'd get it balanced. It will run fine for a little while unblanced, but your busings or bearing will live a much shorter life. Turbonetics is expensive, but they'er so dull that they will definately not laugh. There are several other places, but unfortunatly I cannot remember their names at the moment. Perhaps Travis or one of the other turbo guys would have some suggestions. - KPWSerpiente - 10-10-2005 forcedperformance.com slowboyracing.com agpturbo.com All of these places either do their balancing in house, or have someone that does it for them. Start making some calls. -T - Jeff - 10-11-2005 It is being sent to TurbosUnleashed for a complete HD rebuild. Any thoughts on turbine wheel cliping? - Dave - 10-11-2005 do it if its cheap - Jeff - 10-11-2005 $40 - KPWSerpiente - 10-11-2005 Don't clip it. Sacrifices spool for a little more top end movement. -T - Jeff - 10-12-2005 Ok, here is the other option. Do we think BS? or is it worth the $$? <!-- m --><a class="postlink" href="http://turbosunleashed.com/shop/product_info.php?cPath=21_24&products_id=147">http://turbosunleashed.com/shop/product ... cts_id=147</a><!-- m --> - Jeff - 10-12-2005 PICTURE TIME!!! Here is my cleaning method. I was trying to flush out the bearings but instead I just blew the oil seal. A normal turbo is designed only for 15-20psi of oil pressure...I gave it about 150psi. :roll: However the bearings did come clean...this is the nasty crap that came out and there were tons of nice little shavings in it... hock: So yeah...here is the cool picture 8) Didn't brake a single bolt!!! Here is the wheel assembly you can see the bearing with the scaring. And lastly...my bling bling lines... - Chris - 10-12-2005 nice work, wish I knew more about what you are doing. - ScottyB - 10-12-2005 nice work, and i'm mad jealous of your shop - Dave - 10-13-2005 that 'trooper is gettin down y0. Good work Jeff. You should try to cram a bigger/more aggressive wheel in there while it's apart. - Jeff - 10-17-2005 Did we ever figure out what we want for the XR turbos? I would like the worst one. If the wheels are ok I can put them in my turbo and that should be a major upgrade.
