Good to know that Stage 2 tune w/ stock DP passes so easily even w/ a catless UP. Link to comment Share on other sites More sharing options...

wpmarky Posted April 20, 2010 Share Posted April 20, 2010 Is that with a stock DP with both cats? Has anyone tried going with a gutted stock DP? Link to comment Share on other sites More sharing options...

GoSix Posted April 26, 2010 Author Share Posted April 26, 2010 If you have an Accessport, why not just use the "behave like stock" map for the check? Or would that do more harm than good?

atc5 Posted April 27, 2010 Share Posted April 27, 2010 Wouldnt running a stage 2 tune with stock DP be a bad idea? This should be just fine. I passed with my stage 3 setup with a gutted upper cat and only one single cat in the middle. You should have no problems Link to comment Share on other sites More sharing options...
GoSix Posted April 27, 2010 Author Share Posted April 27, 2010 Hmm..If I get inspired, I'll updated my original post with a summary of what people have posted here. Only if...

RabidWombat Posted April 28, 2010 Share Posted April 28, 2010 Cat-less UP shouldn't matter if the car is warmed up. The purpose of the cat in the UP is to reduce emissions when the car is cold. 07-09 have a catless UP and use a blower fan to accomplish the same thing. I can't see how a gutted stock DP could possibly pass emissions. You'll pass the visual but fail the HC emissions, you'll need a least some form of working cat to have a hope of passing.

Drift Motion Posted May 21, 2010 Share Posted May 21, 2010 so anyone know, say a VF52 turbo increase the emission? i'm thinking i should be fine right? since its an OEM WRX turbo? Link to comment Share on other sites More sharing options...
black318i Posted May 21, 2010 Share Posted May 21, 2010 Not taking the visual in to consideration it doesn't matter what turbo you have. The test is done in closed loop and out of boost. Link to comment Share on other sites More sharing options...

GoSix Posted May 21, 2010 Author Share Posted May 21, 2010 Not to derail, but I really want to drop a VF52 and headers into my scoobie. Someday...someday. Give a man a beer, and he'll waste an hour.

Drift Motion Posted May 22, 2010 Share Posted May 22, 2010 Why not an EVO 16G/TD05H? isnt that alot bigger than the VF52? my friend is down to trade turbo...i think he has a TD05 Link to comment Share on other sites More sharing options...
black318i Posted May 22, 2010 Share Posted May 22, 2010 The EVO 16G/TD05H is a hybrid and I wouldn't say it's a lot bigger. From what I've read and seen on dyno's people have posted it spools close to what the vf52 is capable of and holds up well up top too. I can't stand lag even with the vf40/46, but I am considering it if my turbo ever goes. It's $300 less than a vf52, the CHRA is rebuildable, and said to be more reliable. This is a EVO 16G/TD05H dyno and supposedly conservative. http://legacygt.com/forums/showpost.php?p=2937721&postcount=1981 Link to comment Share on other sites More sharing options...
