Too much smoke out of bugeye..
Rob and TJ did my completely catless TBE install about 3 weeks or ago.
All went well and all. I had researched already that my CEL code would light up (It did). And that i would be running rich without tunning, hence the greyish smoke coming out of the muffler which was not much at the time. Well went to turn my car on this morning, let it idle for a couple of minutes. Drove for next light, And the whole damn place starts lighting up with my exhaust dump. I mean it is alot. Never smoked this bad. Until now. So I get on the fuel and as soon as i let off PLOP PLOP loud backfiring like never before. What could be causing the smoke to get richer and more of it. The smoking is insane now. I am waiting on the tune for some rotors, but you guys think i should go ahaid and get kieth to tune this now before i break something?. Or keep killing mother nature till i get the Rotors? Thanks. I did search google btw bs came up.

Sounds like the turbo may have let go.
What kind of boost have you been running? Its possible that the exh was letting boost creep up and the turbo couldnt handle it. That isnt super common, but it happens and at least in theory could be the cause. Rich smoke is usually dark, grey indicates oil or maybe a little coolant. If bad, its straight up whiteish grey/whiteish blue. I am thinking this is a problem that was already happening (based on your statement that it was smoking a little) that has now finally just completely let go. |

Does the car smoke under acceleration? or just at idle? What color is the smoke? Is the popping just under decel (like a backfire) or under acceleration? |

To answer both of Ya'll questions.. Boost Creep on a 2.0L?? I have never
of that, but i guess it could be. And i am running stock boost, whatever that might be on the 03 wrx. You think maybe it altered going catless? To clear things up. My wrx did not smoke prior to the TBE install. Which I replaced the UP, bigger diameter and it is also catless (might have some thing to do with?) When we did the TBE. The smoke is defintely Greyish. NO black. Or blue.. GREY GREy. And it smells like nasty fuel. The popping is what is making me so nervous. It happens when i deaccelerate. If i am under 2,5k rpm its all good. But if I let OFF above 3k.. All hells breaks loose.. Extremely loud back firing.. The car is running smoother and better since the TBE install and is running the same after this morning. But something has got to be going on under there. Might be worse than i think guys?? |

The smoke is Very light at idle.. But as soon as i get on it and let off
( Along with the backfiring).. Blanket of smoke comes ozing out. |

No, the car is running super rich from something...it could be running rich because of a bad turbo...or it really could just need a tune.
There are dozens of things that can cause it to run super rich like that. |

We installed the Up and Down Pipe on his car.
It left Rob's place with no tune on it since he could not find the map to flash the car with. But with 150K on the stock turbo + you are allowing more air to flow though it without allowing the computer to properly adjust to it will cause the car to run pig rich which will cause either the turbo to go or the smoke from the extra fuel being left unburned |

Did you ever get around to fixing that torn CV Boot?
Since your stock DP was covered in grease and whatnot |

TJ the dealer suggested to replace the entire axle. They said it would be cheaper in the long run due to the amount of labor its going to be. Appearantly bugeye axles are less than 100 dollars. So no I did not fix it yet. I greased it up, and patched it up with some sealer patcher i found at Auto Zone. BTW TJ I did notice where one of the Motor mount pin did not clear the hole.. THe driver's side did but not the other side lol |

i dont know how deep your pockets are but i wouldnt put anything bigger than a ported tdo4 turbo and maybe some grimmspeed pnp manifolds and x pipe. i wouldnt dont much else hp wise until you got the cha ching to do some bottom end upgrading i.e. STi short block. 150k is awesome news but any more mods and i see a spun bearing or worse in your future.

i completely agree with TJ on this...... but im running basically the exact same setup. ported mani, MRT catless uppipe w/ sensor delete, bellmouth catless 3" into spt catback, cobb intake and stock tune. 80k on the clock and i dont smoke one bit. although there is no doubt in my mind we both need tunes i dont believe that tuning your car would solve your problem...... put the stock ish back on and see if you are smokong still or just go replace the snail. |

I thought you were going to load the free XPT stage 2 map on there when you did the downpipe install. I'll PM you the link to it. Load that and see if it helps at all. If not, probably the turbo.
BTW, this map sucks compared to AWDTuning.com's base map, but it should answer the question about tuning or turbo. |
