wow just .. took my turbo off ... and I have these wierd little ... like ant farm holes. How did these get formed?? They look they were put there by mazda.....

I didnt notice the crack till I took the picture with the flash on and my friend natural smooth pointed it out. Guess I need a new one. Args

 

I'm not sure what's going on there but it doesn't look good.

 

Ya crazy huh? There isnt any marks or anything on the exhaust manifold or anything .... *confused*

 

yup, time for a new turbo

 

im guessing it had an exhaust leak for a long time eh.... well if you need an s4 housing let me know i think i have bout 3 or possibly 4 up in my shop.

 

Definlitly not suppose to be like that.

You need a new turbine housing .

 

Its a super effective wastegate

+1 on the new housing. She'll leak like a sive.

 

run lean much ?

 

a poor attempt to fix boost creep?

haha I got this car from a kid in bremerton that "said" he crashed it a week or so before he sold it to me. I found so much rust (on parts that were in the accident so they shouldnt be rusty), spider webs, and crap to show otherwise. *shrugs* I guess I dont really care, but wow haha so many things were bad with this engine and I havnt even started up it up yet. haha My lower rail fuel pulsation dampener's screw was just sitting on top the engine so who knew when that was going to pop off, almost all the vacuum lines are petrified, and if you even look at the wiring harness the wrong way it cracks. :P anyways this is just something to add to the list. I think once I fix / update everything and get a little bit of redline oil through it, it will feel a lot better.

The holes look like they were supposed to be there huh?! Thats what got me so confused but I guess a hireline crack can turn into holes over time. The motor only has 120k on it. *shrug* It has never been worked on or anything. (all the gaskets and what not are stock petrified.)

Also this gives me a change to port the wastegate. Yay. I would like to run this engine at 8 psi all day if It will let me. (on the stock turbo and everything) I dont have anything to bypass the fuel cut so I donno what my plans are yet. 1 psi is still better than my na!

Anyways yeup, got a semi long haul infront of me.

Thanks all for the help.

 

Yeah if it was'nt for the cranks I would just say clean it up but u need a new exhaust housing thats normal for old/aged turbos.. not tha first time I have seen something like that!

Dave

 

It'll buff out...

Probably repairable by a compitent welder....

 

hell with that, i have one that is next to mint i will sell him...PM me if u want it

 

well for the price of shipping or if he meets up with natural smooth ill give him one that doesnt have any cracks in it......

 

Ya thanks mort2002 natural smooth was telling me about cha. I guess you change your turbos a lot?? I'm going to meet up with him this weekend. I would have seen him tonight but I had to do some major accounting homework. Thanks for the backup man. We gata meet up sometime, maybe hit the dyno / renegade raceway.

I think the one that natural smooth has has some minor cracks but they dont go all the way through. We are going to attempt to port my wastegate this weekend also. I'm getting more and more excited to hear it start.
