4 turbos in 2 weeks? WTF??? (sorry for the long story but wanted to be thurough)
ok I acquired a 91 r32 gts-t with a turbo on its way out but came with 3 spares two of which were to have problems one was supposed to be perfectly fine. after installing said turbo it was ok for a few days then i noticed small amounts of smoke again while boosting around 14 psi, i drove to work the next morning and it seamed to be ok and only smoking after i sat for a minute or two at a light. on my way home i stopped and picked up a newish MAF from the previous owner and told him that the turbo swap went fine and it was smoking a touch but not that bad.
10 minutes later down the road a hose blew on my recirculating valve and the smoke started barreling out of my exhaust and i don't mean a small amount i filled the street to the point of people stopping or pulling over because they couldn't see!!!! i pulled over and popped the hood to see oil sprayed all over the engine bay. I also checked my oil level and not a drop on the dipstick so i burnt all 5 liters in 5 minutes. anyways that told me i blew the turbo, so i found another one online (rb20) and put that one in, cleaned out all the piping and intercooler, that one lasted for about an hour!!!! on 7 psi, figured i just happen to be duped into buying a **** turbo, i then bought another one (rb25) from a local guy and everything seemed to check out, very minimal shaft play, no signs of leaks and no harsh residue on exhaust side. i installed that one yesterday, i ran it at idle for 10 minutes or so and any extra oil left in the piping seemed to burn off quickly and it wasn't smoking, seemed to spool just fine and had no visible leaks, I jumped in pulled her out of the garage and proceeded out to the street as i went through first gear no smoke and i kept it under 1 psi to be safe as soon as i switched to 2nd gear and gave it some gas the boost reached maybe 3-4 psi followed by a sickening cloud of smoke as if i was using oil as gasoline!!!!! this as you can imagine didn't make me to happy, i just dont think i can have that much bad luck to have 4 turbos blow in less than 2 weeks.
i do plan on taking it to the local shop so they can do a compression test and leakdown test to see if my stem seals are gone or if my rings are cooked, any other advice would be great thanks
I have taken a few videos as well and put them on youtube so you can see what i mean
