Can The Turbo Be Bypassed?????

[GNflyby]

I have a question, my car has a bad seal in the turbo and shes smoking. I was wondering if theres a way to bypass the turbo until I could replace it? Thanks, GNflyby. :O)

Yes, I have a junk PT52 that I removed the wheels and center shaft from. I replaced the shaft with a bolt, a couple of washers, and alittle sealant. Worked good for me and holds up better than a normal PT52 The car is really slow without a real turbo though. I burned a chip to raise all the timing and pulled some fuel, that seemed to help alittle.

We recently had to do this on my brother's car:

We took the exhaust housing off of a bad stock turbo and put a piece of sheet metal over the hole and held it in place using the "ring" that clamps the center section in place.

We used a brass plug to block the oil feed port off. Make sure you get the right kind of plug. A flat-bottomed plug will booger up the fitting. You need the kind of plug that has the taper inside of it like the actual fitting on the line.

The car ran decent. We didn't hammer on it or anything, but it moved along okay. We were trying to narrow down the source of a startup smoke problem.

HTH,
Jim

That would be interesting to see how fast your car is without the turbo. how fast do you think someones car that has like ported heads, cam, and basically anything else people do to NA motors run in the quarter

I have to say for an all stock motor it's pretty torquey down low without the turbo. I didn't wind it out (actually we babied it quite a bit) so I don't know how it would do in the 1/4. We slowly brought it up to highway speeds and it pulled itself up and down hills just fine.

I've got a stock junk(could be rebuildable) complete turbo for sale if you decide you need to do this and think you might be interested.

If you want to find out how slow your car actually is without the turbo then just take it to the track and unhook the wastegate arm from the flapper. I had to do this once when my actuator wouldn't fit my bigger turbo. Talk about a night and day difference. After you run it a few times with the wastegate unhooked try and find some sucker to run you for money. Then hook the wastegate back up and watch his jaw drop.
