Exploding Turbo?! Shattered Piston Rings?! New SR?! WTF??!!

[jdm_master_X]

wassup guys.

i just wanted to see how many of you have actually blown the turbo on your SRs because i think i might have done that.

well to start of with a little bit of background i live in fremont and attend wyotech (raise your hand if you go there, hah).

i was on 880N heading to Hayward. I downshifted from 3rd (@ 3000 RPM) to 2nd (to 5000+ RPM). the car ran for about 5-10 more seconds then BOOM! i heard what sounded like the cat exploded. then the car continued to run but it would stall and die out with my foot off the throttle. i would have to start the car in the middle of the freeway just to park on the shoulder, and from there i...:

-smelled and actually saw smoke rise up from the downpipe, behind the turbo and 02 housing.

-saw the cat glowing when the car was firing on its power stroke (you could see it backfire, igniting some gas inside the cat)

-had to keep my foot on the throttle to keep the car from dying

-feel the temp of the entire engine (radiator didnt burst when i opened the top so it didnt over heat from the boost) to figure it was at op temp

-watch oil drip on top of the downpipe

i should have paid attention to the small drippings of oil and the exhaust leaks i had a long time ago but stupid me just let it go. so now here i am knowing or being told of a couple of things.

-it could just be a turbo problem...lack of lubing, oil ingestion, etc. so i would probably end up buying the coveted disco potato. then that would mean a new downpipe, and full straight exhaust.

-my instructors said i MIGHT HAVE shattered the piston rings. so i will run a compression check soon as well as check the cam timing to see if it might have skipped a tooth during the downshift. if thats the case and its all bad, then ill completely rebuild the SR.

soo...why did i post? simply because i wanted to see how YOUR CARS were acting when the turbo died. share with me your experiences so i know that its just the turbo.

i would also like to know if any of you have run that GT28RS setup in your cars and how you made it work. i hear its pretty straightforward.

anyways, drop a line and lets talk about it. haha take care guys.

Try asking this in RWD SR section too. probably get more response.

Sounds more like your hotpipe or somewhere along your intercooler piping came off under the boost making a loud "POP" noise.
