ok just got back from junkyard and got a garrett t-3 turbo off of a saab (think like a 8. The manifold was still bolted up to the turbo because the junkyard was closing so I never got a chance to take it off while I was there but I just did once I got home and noticed that there are like 2 tiny like hairline cracks (very small) in the exhaust housing I guess. Do you think this will effect the turbo much and do you think I will run into problems if I still just run this turbo or do yall think I should keep looking for another turbo? Also is this common in these turbos or for any for that matter. I was reading a write up on this site and the guy said that it dosent really effect anything sometimes and they are normal wear. Well thanks for the input. Just wanted yalls opinions

I have the same turbo with a extremly small hairline crack between the turbine channel and the wastegate hole, but I'm not sure if would still be an equal turbo vs one that isn't cracked.

Funny people always say the garretts resist cracking better than the mustu turbos, but your turbo, my T3, and my mustang friends T3 have exhuast housing cracks and I've never seen a mistu turbo that has any cracks ( neither factory stealth turbo, TEO-4H daytona turbo, TD04h-13G WRX turbo ). Luck of the draw I guess.

I've heard wastegate cracks aren't that bad, but turbine channels and outter turbine housings are prob. serous problems.

If your running 20psi on the intake side, your running at least 30psi in the exhuast manifold and turbine housing..

 

well u think it would be ok to use for like short while?

 

"89hunchback" im fastcivicboys freind and we got a mistu TD05 turbo the other day and the housing was cracked, thats why we went and got the T3 turbo off the saab. i guess we just keep havin bad luck and finding cracked turbos.

 

lol...ive had 2 t3's with cracks in the exhaust housing(one was pritty bad) they seem to always crack from the bolt holes.just make shure that the wheel ist hitting the housing and go for it, the downside is it might slow down spool time especially if the cracks are into the wastegate opening(like one i had) or can be seen from the outside. iguess these cracks just happen from the housing heating up and cooling dow and from getting hit with water when hot. i just got a ihi turbo off a subaru and it looks to have no cracks in and is in better shape...even tho it is older

 

Yeah, I havn't ever seen a used T3 housing without any cracks. If you say they are just hairline cracks, you can still use it. Small cracks aren't a big issue, it's the big cracks that go straight through the turbo housing that you have to worry about.

 

That happened to me too.I pulled 3 turbos and only 1 had no cracks! It suck but you sometimes get lucky.

 

I gotta 14b that is PERFECT...EXCEPT for cracks in the exhaust housing....oh well, boost it till it breaks....

 

I have a t3 off of an 87 saab and my housing is cracked too. I'm just gonna use it anyway and keep looking for a good one or buy a new one. Looks like they go for about $70-100 on ebay.
