Default Replace or Repair? Stock Turbo Advice

Hello All,



A few weeks into owning my 2005 WRX Wagon, I noticed an interesting problem. There is a rather large piece (approx. 1"x1.5") of my turbine housing that has cracked and fallen off at the intersection of the turbine housing and the uppipe.






I have no real idea when this happened, and was hoping to get some help determining what to do from here.



After searching around on the forum, I am relatively certain that I would like to keep the stock TD04 Turbo and get it ported and polished. That said, I am uncertain as to whether I should buy a new (lightly used) TD04 from someone on the forums, get it ported and polished, OR if I should just remove my turbo, replace the turbine housing, and port and polish myself.



Everything seems to be functioning well. I have a tough time spooling up at low RPM, but once I hit the powerband I boost up to .07 MPa no problems. The car has 128,000 miles, and to my knowledge the turbo has not been replaced. As far as I know, I am running completely stock at the moment but I have a feeling that the previous owner had a fair bit of modifications, and went back to stock to sell.



Any suggestions or advice would be greatly appreciated. Thanks in advance.



Ben

If you have The time buy another turbo and have it prepared right. That way you can keep your car on the road and then just swap it out and sell the old one later. Just be careful with the turbo falling apart and damaging the engine while your driving. It sounds like you mostly just have potential leaks at the turbo which isn't good for the motor long term.

there are plenty of companies that can rebuild and upgrade a TD04.

these guys seem to do a good job: http://www.midwestturboconnection.co...ct-p/30002.htm

there are plenty discussions about the TD04L-19T, here is the big one: http://forums.nasioc.com/forums/show....php?t=1623665

If your uppipe is still stock, please replace it with a catless one when you replace your turbo.

Yeah, definitely get on replacing your uppipe if it is still the stock catted up pipe.

Thanks for all the help everyone, I really appreciate it! After further research, I found out that I do already have an aftermarket uppipe. It looks like a nameless one from ebay or something, and it is just a straight through pipe, no cat.

In this case, do you think it would be a better option to rebuild myself or send it into the pros like Titter said? I am not on a very tight budget, but would ideally like to spend around $600

Also, while i'm in there I will probably be replacing my turbo inlet, should i consider replacing anything else?
