My 'down2turbo' turbo is toast...
 

well today i noticed that my car was smoking excesively, and kept getting worse in the day. I poped my hood to check it out and my ebay filter was kinda busted off the rubber coupler thinggy, so i go ahead and take off the elbow to check for shaft play. The turbine shaft had play like a mofo! it was clanking around just by wiggling it. I took a closer look when i got home and the compressor housing is fucked.

just my luck, ive been waiting all winter to run at the track, which opens in 2 weeks and this ---- happens. Now i gotta park this bitch till i can get a new turbo.

i really liked this turbo too... i don't think i'm gonna buy another ebay turbo though... any suggestions?

oh by the way, ive only had this turbo for 4 months and no more than 6000 miles.

sorry to hear that but dont feal bad. if it makes you feal better im not even boosting yet.

Re: My 'down2turbo' turbo is toast...
 

Contact them and see if they will help you out.

Re: My 'down2turbo' turbo is toast...
 

agreed, i put 10k on a d2t super 60, when i removed it it was still looking and spinning brand new... maybe a oiling issue??

Re: My 'down2turbo' turbo is toast...
 

heh my Down2turbo lasted 15k miles and 6 months. Mine smoke in the am after it warms up. It only leaks when it sits for awhile and the shaft play is NUTS!! It's my fault though for not having a proper PCV setup. high oil pressure killed the seals in the first few months and I just neglected it ( didnt know any better). I thought his turbo was a pos cause from day 1 it spit oul out the casing and now it leaks internaly. Too bad I am way past his 90 days. He will rebuild it for 250 bucks ouch!! I have his number his name is Jason. I would post it but right now hotmail is not responding.

Re: My 'down2turbo' turbo is toast...
 

Both bad turbos in this topic sound like other issues killed them--not the fault of the turbo. evosol, didn't you say your filter came off?? Meaning, the turbo was sucking all sorts of bugs, dirt, sand etc. into it? that will kill bearings quickly, and the other one, well, high oil pressure will kill most seals anyway.

Re: My 'down2turbo' turbo is toast...
 

sounds like you guys got bad remans... it happens

Re: My 'down2turbo' turbo is toast...
 

well i used a oil resrictor and the oil drain i have is a straight shot into the oil pan. The filter couldn't have been off for more than a day or two. so i dunno what the deal is... i guess its worth a shot to contact d2t.
about a month ago, i did start to notice a little bit of smoke in the mornings or if i sat for a while, and then it would stop after it warmed up. i just figured it was my valve seals, since my head has about 150k.

---- i dunno. all i know is that i feel hella depressed b/c i put in hella time to run it at the track, and now i have no money to buy a new turbo b/c tuition for school is up. :-\

Re: My 'down2turbo' turbo is toast...
 

i was just running stock PCV setup. i don't see how high crank case pressure can effect oil pressure, causing to blow seals. can someone enlighten me? i did notice i was getting about 65lbs of oil pressure on my gauge, but should the -4 oil feed and restrictor take care of that?

i just did a search on my paypal purchases, the turbo was purchased mid October of last year but i didn't insatll it till mid december... which means i'm way over the 90 days from purchase.

Re: My 'down2turbo' turbo is toast...
 

isn't there some kind of warranty?

Re: My 'down2turbo' turbo is toast...
 

Come on evosol, everyone knows that whenever an ebay turbo fails it's the oil lines' fault. :D ::)

Re: My 'down2turbo' turbo is toast...
 

Yeah I ran the stock PCV setup too for a long time. Now get this...after going to a catch can and routing both the PCV AND vent to the intake (pre-turbo) pipe the oil stopped leaking from the turbo housing. My oil pan also stopped leaking lol wtf? I talked to the guy who built it and he told me that CAN happen. What did the most damage was when I first put it on I had NO oil restrictor. I then got an adjustable one that the friggin screw came out and once again spit oil out everywhere. Finaly I got a restrictor from ATP turbo and all has been good. But the damage has been done and knew it would need a rebuild. Just in the past few weeks has it been smoking bad. At first I thought headgasket gotta be (cause the turbo didnt smoke since I fixed the oil problems). Replaced the headgasket and installed some ARP studs. Still smoking wtf? Compression check 185 all 4. Did a leakdown maybe its valve seals. nope all is good. Ring lands?? Put on a second head gasket and poppped out all 4 pistons. Nadda everything checked out good. when I had the turbo off I even checked for oil but never saw anything. the ONLY conclusion I can guess is the oil bakes in the casing after I shutdown. When I first start the car no smoke, wait 10-15 minutes and around 150-160 degrees ONLY then it starts to smoke and smoke bad!! I cant even see out my back window its smokes so much. I romp the gas a few times, drive it down the block and about a half mine later its gone. It wont smoke again all day long wether idling or on the gas hard. Not until the next time it sits for a few hours. I am guessing the baked oil is burning off once it heats up. The shaft play is pretty bad though if I push on it hard enough I can get it to rub the housing ouch!! Sending mine out friday :( quoted $250 if it needs a FULL rebuild. Cheaper if its just seals apearently he uses a different kind of seal now.


Heres his number. 1-205-339-0616 ask for Jason 8-4 central time.

Re: My 'down2turbo' turbo is toast...
 

I think they failed due to other issues, but Jason is a cool guy. Talked to him personally on the phone when I bought my turbo. Hope things work out for you buddy.

Re: My 'down2turbo' turbo is toast...
 

well if the turbo did fail b/c of some type of user install, or stealth's faulty oil lines ;) then i'd like to get to the bottom of that before i put in a new one.

Bizzar, thanks for the #. i'll have to call them and see what the deal is, if its gonna be 250 then i might as well just pick up another one thats already rebuilt, and save money on shipping.

My current turbo is t3 48/60 60 trim, does anyone have any opinions as to going with a t3/to4e 50trim w/48 turbine?

Re: My 'down2turbo' turbo is toast...
 

if you ask me.... 65psi of oil is WAY too much evosol, i have a ball valve on mine w/ a gauge @ the ball valve and it never goes above 35 psi and 20 at idle.... 65 psi pushing against rubberband seals that are encased in a 1200 degree oven dont last long.

just my $.02

Re: My 'down2turbo' turbo is toast...
 

I'd definately consider it if it's not too much more money......make a bit more power with less boost

Re: My 'down2turbo' turbo is toast...
 

you can turn that ---- wayy down mang... for real, turbos will live on like 10psi oil pressure no prob

Re: My 'down2turbo' turbo is toast...
 

well, 65psi is at a cold start up, and about 55-60 warm, and thats before the APT oil restrictor going to the turbo. So then, do i really need to get some type of valve to turn down the oil pressure to the turbo, even with the restrictor?

i guess it wouldn't hurt with my next turbo.

Re: My 'down2turbo' turbo is toast...
 

i restricted my new t3/t4e to 35psi max

Re: My 'down2turbo' turbo is toast...
 

If you are still using the stock PCV in the stock location, when you go into boost that pcv will shut and it can't vent. Either take the hose off to the intake mani or reroute it with a catch can. You're just going to kill another turbo. routing back to the pre-turbo intake will help vent. Same with the valver cover vent it needs help. Like I said my oil leaks stopped once doing do. Mine is a t3/t4 T04B 48/60 with a 54 trim. I love the thing and dont want to shell out 350 bones for another turbo. Id rather pay 250 plus 25 shipping. He said he will pay for shipping back to me.

Re: My 'down2turbo' turbo is toast...
 

well i guess i'll have to fix something up for my PCV system. i want to try the exhaust vac system, and see how well that works. Plus, install some type of valve to the oil feed line with a temporary gauge to monitor psi. i don't want to have to go through this ---- again.

Bizzar, now i'm gonna have to ask you how well you like your turbo? when do you see full boost on your d15b? i'm 90% positive that i'm gonna go with the t3/t4 50trim.

Re: My 'down2turbo' turbo is toast...
 

I absolutly LOVE it. Spools very nice even in traffic. I see full boost (10psi) BY 4200rpm. Starts to build around 3000-3400. Its got a nice kick in the ass too once it hits full boost but not laggy at all. Lag is way over-rated and its plenty in the powerband. Pulls very hard to redline at 7300. Hers a short sound clip I took awhile ago. This is 0-90mph.
