Author Topic: Running NA with a turbo (Read 5931 times)

While I am getting money for my turbo to be fixed. can I run it with no oil, with a turbine wheel with the vanes ground off so it won't turn, no vanes in the VNT. Or will the aluminum on the compressor side get to hot? It would be a pain to have to make a new exhaust for a temporary condition. Or maybe put a bolt & washer in place of the turbine & shaft and just remove everything brass & aluminum? I have spare center sections so can sacrifice one if need be.

can you just put a N/A exhaust manifold on?
do you need one? i have one from a dasher that has the 4bolt connection i even have the bowl style that takes the clips but the dasher/vanagon does have the slight exit angle that your longatudional motor placement requires!

My turbo was a VNT 17 from I think a Nissan which I bought off e-bay from Japan, so it had a totally different exhaust housing. So I would have to remake the exhaust pipe to run without a turbo, which I don't want to do. I may just try a bolt in it to plug the hole.

When my last turbo blew up (500 miles from home) I just unhooked the intake and made an air filter that attached to the manifold so I could at least have filter air,and not be sucking through the turbo then I removed the turbine and shaft but I don't think I needed to, proceeded to drive it 532 miles home. I had to plug off the oil feed and drain as well. Oil feed was self explanatory, it would siphon the oil out of the pan through the drain then out the back, talk about smoke.

i think if you do what zukgod did but also leave the shaft in but jam it so it cant spin, you should be good. i wonder how much 'lag' you would have with an exhaust wheel that doesn't spin? but you should be able to remove that as well... do you plan on keeping any bits off of the turbo?

I put a bolt in it. Got it running right now trying to blow/burn all the oil out of the exhaust. The shaft broke at the thin part in the bearing(VNT 15 shaft) Compressor scraped a little, but hopefully it's still salvageable. Oh yes, it makes a lot of smoke. Already had someone stop by thinking there was a fire! :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol:

So how long did it take to burn/blow all the oil out if the exhaust? I got probably 1/2 quart out just idling(3krpm), even drilling small drain holes in the muffler. Then took a 3-4 mile drive around some back roads, fumigating the whole way except the downhills when it cooled off enough. It is better, but I bet it will still lay a nice white cloud next time I take it out.

Crudely spray-paint some flames on the side of it and wear a full coverage helmet everywhere you drive.....keep giving everyone you see the "thumbs-up" sign!!!! :roll:

I went a good 40 miles @ 1000+ deg on the EGT's before it all burnt off.

Was quite a site on the way down the other side of the hill.

There was brite red ambers flying out the back of the car, I thought they were pcs of molten piston at first..

Looked like th 4th of July!!
