BoostedBalls Posted February 16, 2008 Share Posted February 16, 2008 I have a stock turbo in my 91 legacy with auto trans. I'm upgrading the exhaust and probably the turbo as well. What turbo is on my car? Is the WRX unit a better selection? Are the up pipe and down pipe flanges the same? I plan on doing some drag and rally racing with this car. I was planning on switching over to Garrett but it would be easier to just stick with the Subaru stuff (if the flanges match up). any ideas?

Crawlerdan Posted February 16, 2008 Share Posted February 16, 2008 vf11 on the leggo tdo4 on the wrx they are the same flanges intake requires some moding on the tdo4 but i am confident that you can do it i suggest a vf22 or vf39 a td04 isnt much of an improvement try a 16g or 18g also go check out legacycentral.org Link to comment Share on other sites More sharing options...
