Smoke from a Turbo'd Prelude?

Hey Guys,
First off, I'm new here, but been a long time lurker

I've had my 5th gen for 2 years now, but unfortunately it's tiptronic :( And lately I've been having a few issues with it and I feel like the tranny will die sometime soon, so I'm looking to switch up to a 5spd. Yes, I could buy a different car, but I'm too in love with my 5th gen, and need another one.

Anyways, I was looking at someone's turbo'd lude with a greddy turbo installed. It has a recently rebuilt engine (25k or so) and the turbo kit which was installed around the same time I believe. Just recently, the turbo seals were redone, and then the car was put in storage. When I went to look at it, there was quite a bit of smoke coming out of the exhaust, looked blueish/white (oil) and it smoked quite a bit when the car was floored, but was still smoking even at regular driving speed/acceleration. I was told that when the seals were being replaced on the turbo, some oil, not too much, spilt down the exhaust, and that it's just some oil in there that needs to be burned off.

I'm really liking the car and I trust the guy because he has a pretty good rep, but I'm just hesitant on the smoke and that it might be something worse than just burning off the oil. Is there any way to confirm this? The car isn't insured right now so it can't be taken out on the freeway to burn off that oil. Records are also provided about the engine rebuild. Oh, before I forget, it's toned down at 6.5 right now.

And say it's not just a matter of burning off the oil - what else could it be and how much $ would I be looking at to fix-er up. There were no leaks or smoke under the hood and no leaks underneath either.

Also - is a bit of smoke normal from a turbo set up? Because I swear I've seen quite a few vids of cars running some boost, and I've seen some smoke out of the tail.

Any advice or help is much appreciated! Thanks guys.

Note: I'm somewhat of a noob to boost, so bare with me

Re: Smoke from a Turbo'd Prelude?

You'll want to look into boosted cars alot more before even considering purchasing one. Let alone someone else's project - which is always an ire thing since you could be buying another headache.

Yes, if oil was spilled, it would take a bit to wear it off. The oil line to the turbo could be leaking as well, or the car may have a test pipe vs a cat (which would smoke a bit more)

Does the motor have a warranty from the shop that built it? That'd be a plus if so.


either way - blue smoke is oil, be it from accidentally dripped down the pipe or a leak somewhere in the bay. So it would just be a matter of replacing the seal if that's the case.

Re: Smoke from a Turbo'd Prelude?

Thanks man.

Is riding the car with the piggyback ecu that came with the kit a bad thing? It hasn't been running at high boost so could this cAuse problems if it wasn't tuned with a hondata or with a custom tuner and rather just the piggyback?

Also I don't believe it comes with a warranty as he's had the new
Motor for about 2-3 years just hasn't put much mileage on it since it's a summer car and not even a dd in the summer.

As for the cat/test pipe, it had an apex-I but now it's been changed to an R&D. The turbo is a greddy TDO5/06 with greddy intercooler and standard greddy turbo kit parts. Throttle body/intake manifol port and polished. An resleeved 88.mm bore and arias pistons.

I also read that the oil burning could be signs of a dying turbo...and of course a dying engine though i don't see that this could be the case with such low boost and the recent rebuild.

I definitely have lots to learn about boosting but Im really tempted and I kind've need a new ride soon. I don't mind if I'm at low boost...at least not for now and once I learn more I was thinking of going the turbonetics route.

Any more advice? Anyone with a turbo'd ride in Toronto that wouldn't mind checking it out for a final decision with me? I'll pay you or buy you dinner ;)

Thanks again fellas.

Re: Smoke from a Turbo'd Prelude?

If it's only on the piggyback that came with the turbo, it really should be on something to better tune the engine. Either something like a Greddy E-manage (piggyback) or if your state inspection permits it, swap to OBD1 and go full hondata or something.

Yeah, that could be a sign of a dieing turbo or something gone wrong from it sitting so much. Thus why it's not so great buying someone else's project - the "hidden" issues are almost endless. You may end up putting even more money into it but that's entirely your decision.

best of luck, keep us updated!

Re: Smoke from a Turbo'd Prelude?

That's the thing - I wouldn't mind putting in another grand into it if I have to, just because it's so clean and I want a lude that I can keep for a very long time. The price has been dropped and is pretty low, which I guess could be a good or a bad thing at the same time, though even without the turbo, it would be worth the price. Main thing I would be worried about is the lack of tuning and/or the turbo causing problems to the engine, since I don't want the engine blowing on me anytime soon.

Ahhh don't know what to do.
