D-VO Posted August 25, 2014 Share Posted August 25, 2014 I purchased a remanufactured VF52 recently. When it arrived everything looked great. Fit it on the car and everything looked like it lined up pretty well. When I tried to bolt the intercooler on, this was the result: http://i.imgur.com/7DQtr7l.jpg Everything else fit very nicely, including the oil/coolant lines and the up-pipe. Using the trusty iPhone on a level bench, we find this result: http://i.imgur.com/5sds58u.jpg A senior member of this forum has told me that all VF series turbos should have the outlet flanges on the compressor / turbine housings parallel to each other (180* opposite face of course). This makes sense to me. In my brief back-and-forth with the seller, he has agreed to make it right, which I am pleased with. He has said that he this is how he normally puts them together... I am curious whether this is an LGT-specific fitment issue, or if the turbocharger was just assembled incorrectly, and the 08+WRX fitment uses this clocking configuration. Just trying to expand the knowledge base here. Thanks! Link to comment Share on other sites More sharing options...
Moderators BarManBean Posted August 25, 2014 Moderators Share Posted August 25, 2014 Should be the same for WRX and LGT. But have you tried reclocking it? I'm not sure if the VF52's are pinned or not, but if not you can just loosen the clamp there and gently rotate the housing to see if you can correct it.

D-VO Posted August 25, 2014 Author Share Posted August 25, 2014 I thought about that, but the oil return and coolant lines looked like they fit damn near perfectly. I also didn't want to take apart a brand new unit. Link to comment Share on other sites More sharing options...

Moderators BarManBean Posted August 26, 2014 Moderators Share Posted August 26, 2014 So did you try to reclock it, or no? It's technically aftermarket for your car and not OEM if it's from someone other than OEM. Sometimes you have to tweak things to get them to fit, even high-dollar parts. Ask me how I know. If you can simply loosen the band and rotate things to fit, you should do so. If the turbo is "pinned", then don't bother.

D-VO Posted August 26, 2014 Author Share Posted August 26, 2014 It's not pinned, but the oil return line and coolant lines fit perfectly, and I didn't want to screw that up or risk some sort of shaft misalignment because I was impatient. There were no warranty issues, just more risk than I was willing to take on as a hobbyist. Link to comment Share on other sites More sharing options...
Max Capacity Posted August 26, 2014 Share Posted August 26, 2014 Rotating the housing will not effect anything else. Do you still have the old turbo ? look at it. loosen the nuts and rotate the compressor housing. People do it all the time. It's no big thing. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

JmP6889928 Posted August 26, 2014 Share Posted August 26, 2014 ^^Can't do that. Housing BETTER be sealed with high temperature silicone and the only way to clock the compressor housing is to: Remove vacuum hose Remove coolant pipes Remove wastegate actuator and housing bolts GENTLY remove compressor housing using a soft hammer, being extremely careful to not let the housing touch the compressor wheel or it could damage the wheel, housing, or both. Remove all of the silicone on the compressor housing and compressor backing plate Fit and mark the compressor housing using a level to make sure they are both on the exact same plane Sparingly apply high temperature red silicone to the housing all the way around where the backing plate fits Line up the marks and fit the compressor housing onto the backing plate very carefully taking care not to damage the compressor wheel or housing Put bolts in and mount the wastegate actuator, taking care to not overtighten the bolts Replace E-clip on wasregate arm Replace coolant pipes, putting in support bolts and being very careful to tighten the coolant banjo bolts evenly but not too tight AND...IHI turbos are all pinned on the exhaust side unless someone broke the pin or cut it off during rebuilding.

JmP6889928 Posted August 26, 2014 Share Posted August 26, 2014 If there is no silicone on the compressor housing, you will search FOREVER to find that boost leak. It will be small but right where your boost pressure is the highest, so it will definitely affect performance. Link to comment Share on other sites More sharing options...
D-VO Posted August 26, 2014 Author Share Posted August 26, 2014 Good info for sure! I sent the first one back already and got one from a different vendor, who I was able to speak with and confirm the clocking. Link to comment Share on other sites More sharing options...
Max Capacity Posted August 26, 2014 Share Posted August 26, 2014 JmP, I know you rebuild these. I'll have to look at my old vf40, I thought for sure I could have just rotated the compressor housing, like Garrett. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

D-VO Posted August 26, 2014 Author Share Posted August 26, 2014 I'm a mechanical engineer by trade and looking at it, I didn't want to break that seal and try to put it back together in my garage. Maybe I'll try and rebuild a less blown up one to get the experience. Link to comment Share on other sites More sharing options...
Max Capacity Posted August 26, 2014 Share Posted August 26, 2014 I just looked at my vf40. There's a red seal on the compressor housing. Loosen the bolts and nuts, give the flange a tap with a hammer and it will rotate. Mine is in pieces but I did put the center section together with the compressor housing. It will rotate. http://i185.photobucket.com/albums/x40/92Si/DSCN6536_zpsa61549ea.jpg http://i185.photobucket.com/albums/x40/92Si/DSCN6537_zps39ae841e.jpg 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.
