Temporary turbo to N/A conversion?

[94gsr]

I just poured about 1/4 of a quart of oil out of my intercooler, and my exhaust looks like a bunch of cumulonimbus, (sp), clouds. So basically, my turbo is spitting oil out the exhaust AND into the intake. While I'm in the process of waiting for a new turbo, I still NEED to drive my car. The problem is that it's getting so much oil though the intake that it won't idle. Consequently, I was thinking of doing a temporary turbo-to-N/A conversion, if it's possible. I would connect the turbo oil & coolant lines directly to each other, put the filter & MAF somewhere in the UIP, and seal off the exhaust turbine housing. I realize that it would have the pick-up of a three-toed sloth, but would it work? If it would work, is there anything else that I would need to do?

I don't think that is possible due to the difference in the Internal workings of a NT and turbo. But I could be way off the mark.

:laugh: He said three-toed sloth!

would you run really really rich do to less air coming in????

The turbo merely pressurizes the intake. If you take the turbo out of the mix, it's just a normal internal combustion engine. The air/fuel mixture should stay @ spec being that all of the air getting to the engine will still be measured by the MAF, allowing the ECU will regulate fuel accordingly. The exhaust is a no-brainer, just gotta plug the hole for the turbine, and with the coolant & oil lines connected, I'm thinking that everything should be fine. I just wanted to check & make sure that there wasn't something else that I would need to do...

I think only the oil squirters in the rods but that wouldn't matter (i dont think)

It will not run properly, You think it will, but it won't. For some reason these cars don't like it when you try funky stuff like that. It will be like this. From stop: give gas, take foot off clutch, 1st gear fine, (maybe) 2nd maybe as well, but third, and if you floor it it may flood and bog down, ever had an intake pipe come loose?!

There has to be a reason for that. You don't just say for some reason when there really is no specific reason for it to happen.

When my 14b spunn apart all I did was take the maf and put it right on the throtle body, pluged the lines and drove it for a month cause the dam mutts were on backorder. It took time to accelerate but it got me around till I got the mutt. My car sounded funny, like a honda.

So yes it can be done and the car will still run, I got mine up to 100 MPH once cause I wanted to see how fast it would go.

Why don't you just connect the oil and coolent lines together, remove the turbine wheel and just run it like that. No oil mess, no boosting, and no extra money spent except on fluid changes.

Ok to give a guess why it would do this: can you get the car up to 50 w/o creating boost(this is with your turbo on)? I say no, the cars are designed(ecu) to know that there will be boost at a certain throttle amount, hence, you will run rich and bog.
I've never done it my self, but this would happen. You can damage your motor this way!

CMC, actually that's incorrect. These cars are designed to deliver an amount of fuel for a specified amount of incoming air. Take the turbo out of the equation, the car sees less air, and delivers less fuel. It doesn't really care what kind of boost you are running. That's why we can turn up the boost, or down the boost if you want, and the car is just fine with it.

CMC, when trying to get a turbo car up to speed w/o creating boost, you have to limit the throttle position as well, so you're only running at partial throttle in addition to no boost. If you could hold the turbo still and floor it, you could easily reach 50

The turbo on my car crapped the bed, so to speak, on the way home on 93 north in Massachusetts. I still had 50 miles of journey ahead of me, and no other way home, so I had to continue on. Luckily the only thing that broke was the exhaust turbine, so no other damage resulted. Anyway, I had to keep the throttle very very low, because when the turbo wanted to spool, it would just make a terrible noise, and I didn't want to break anything. So effectively, my car was a non-turbo, with the throttle limited to.. I dunno say 25% Even so, I was able to keep up an average speed of 45 or so. Un-turboing a dsm would be just fine. It would probably be depressingly slow, as in 80 mph max down a hill with a tailwind, but oh well

I was actually thinking of doing that myself, with the bypass just to make my car work in the meantime. But I'm lazy.
