trepetti Posted June 10, 2012 Share Posted June 10, 2012 I need to know what is the stock turbo on my 09LGT, along with some suggestions on a modest size upgrade. I had the oil feed pipe on my 09LGT crack. I have all the piping /gaskets, but the unanswered question is 'Has the turbo been starved of oil and do I need to replace it'? I am running a stage 1 tune and have no intention to go any more, except maybe a new intercooler and bigger injectors. Any help is appreciated. Thanks Link to comment Share on other sites More sharing options...
cypher0117 Posted June 10, 2012 Share Posted June 10, 2012 I just had the same question about my 05. I found this: http://legacygt.com/forums/showpost.php?p=3614476&postcount=3 Link to comment Share on other sites More sharing options...
Code Posted June 10, 2012 Share Posted June 10, 2012 Intercooler is reccomended if you go past stage 1 Injectors will only be needed if you get a larger turbo or e85. At that point you should have already done: down pipe, fuel pump, clutch. If you get a larger turbo, depending on how much peak boost you'll be running, you should also be considering: ebcs, bov, intake, suspension/brake mods to keep her rubber-side down IMHO you should spend a few days searching this site, then come back to This thread and ask some more detailed questions.

RabidWombat Posted June 10, 2012 Share Posted June 10, 2012 Pull the turbo check for shaft play. Stock turbo: VF-46 Mild upgrade: BNR 16g (tune required, downpipe recommended, no other mods needs) Modest upgrade: 18g/VF52 (tune, downpipe, possibly injectors) Link to comment Share on other sites More sharing options...

dr_sharp Posted June 10, 2012 Share Posted June 10, 2012 I had my oil feed line crack and the turbo was fine. But I lost almost no oil at all before I discovered the leak. This happened around 10k miles and the turbo was still running strong at 80k miles when I upgraded. lol Link to comment Share on other sites More sharing options...
dr_sharp Posted June 10, 2012 Share Posted June 10, 2012 you should also be considering suspension/brake mods to keep her rubber-side down :lol: well worded lol Link to comment Share on other sites More sharing options...
Max Capacity Posted June 11, 2012 Share Posted June 11, 2012 I'd go with a vf52 and get it tuned. If you haven't upgraded the DP it's a go time to do it. Also if you can, remove the studs in the up pipe and replace them with good bolts. I got my bolts and nuts from the dealer. It's much easier to install the turbo and new oil return line, hint, hint, hint. Use anti-seize compound on the nuts and bolts. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.
