So today my turbo gave up, exhaust wheel went bang

.

What i wanted to know is, is it possible for the fragments from the exhaust wheel to be projected back up the manifold into the engine?

Yes, that's how I blew up my first 450hp CT26 and my 3S-GTE.

was doseing it back in 2001, and a lot of boost

nek minnit....... actually it was more like 3 months later, back to normal boost and BOV, driving home normally and car randomly stalled.

Checked compression: 30, 0, 0, 0 or some shit.

Bores all fuct.

Was doing about 0.5 bar on partial throttle around 4k rpm.

Still have the fuct wheel, looks like someone took all the fins out and you're left with a core.

You'd be unlucky for it to happen - do you still have a cat?

I'll have a spare CT26 available tomorrow.

I wouldn't much for it, maybe $100 since you are turbo less

Yea there is nothing left of my exhaust wheel, it's all MIA.

Reason I ask is that after it happened engine started to knock, sounded like it was coming from up top of the engine, then seems to have gone away after it's cooled down

Not primary one, got replaced with 3' DP, do they have a secondary cat?

Pulled the exhaust manifold off, can't seem to find any evidence of shrapnel, but will do a comp test just in case

by **AE82 FXGT** » Tue Nov 15, 2011 11:36 pm

maybe crazy idea, but could you take the plugs out and twirl a magnet around in each bore before you start it up again? Just in case?
(btw, not sure what the fins are made of...)

I've already driven it for 20mins since it happened, as I had to drive home from my parents house, it was a very very smokey trip home

I had a factory cat on mine, were you boosting while it happened?

I think your engine is toast.

Yea was about 3000rpm and 6-8psi

I'm thinking that to, but secretly hoping not

The coffee cups at work disagree.. might be something to do with the fabricators leaving them on workbenchs while angle grinding. Nothing like a rusty coffee to kickstart your day.

Pretty much the same then.

Compression test next and then buy a real 3S-GTE? :lol:

Thats what had happened to my 2JZ-GTE I bought, bores, pistons and head were rooted.

More than likely detonation first, bits of engine went out through the turbine and killed it. You won't get bits of turbine going back into engine.

which also means you'll have a BHG

by **MAC_HATER** » Wed Nov 16, 2011 6:56 pm

ouch man! sorry to hear that!

if your engine is unscathed which i hope it is - there is a CT26 here in the garage - its condition is when we pulled it off "boosts well and smooth, no untoward noise but possibly oil seals are letting oil leak into intake"

if you want it im sure you can have it real cheap given its condition - ill hit up the owner of it if you might be keen to recondition it or something
