For the wastegate you can either dump it to the atmosphere it or dump it into the exhaust. No real advantages of one over the other. External dumps if dropped in the engine bay may raise engine bay temps up some. They're also louder since there's no muffler or anything. If attached to the downpipe, the exhaust gas flows out with the rest once it bypasses the turbo.

Look up pics of wastegate dump and you'll see how they go.

Well after a week of putting th turbo in. It was WASTED money. First we crank the car up and it was smoking white smoke like no other. It took 15 gallons of oil to even make it home. I get home, pop the hood and the WG was on fire. My buddy said the seals in that part of the turbo that goes into the manafold has bad seals so the oil is just sitting there burning.

Oil pressure would be good at 45 to 50psi then would drop to 20 in a matter of seconds. Just going back stock, save money again and just buy a gsx. Just got to try and sell all the extras I bought for the turbo.
Thanx for all ur help anyway

Tryin to rotate the turbo cause I have the feed line facing to radiator. Thats prob the problem with my oil. I got all 4 bolts loosen to rotate it, hit it (softly) with a hammer and can't get the turbo to rotate at all. Any other way to get it to move?

Ok ya you have the feed line on the drain. When you're able to rotate the center section, you want to rotate (or "clock") it 90* TOWARD the front of the car. This will put your current oil feed facing downward. Take that off, move up to the top. The oil drain line then goes where the feed was... on the bottom. Again, you want it straight up/down. The oil goes into the turbo, lubricates it, then drains down in one quick motion. You don't want the oil sitting there.

I couldn't find any more info on clocking the turbo, but keep working at it. Try pulling the center section while trying to turn. Even a little bit of tapping toward the drivers side on the center section may help as well.

From the beginning of this I knew it was not going to end well. It just seemed like you needed to do more research before tackling such a project. Dave sent me the pics of your car and you did infact have the oil feed line on the oil drain and the oil drain line connected to one of the water feed lines. Im sure the car was pouring out oil so you shouldnt have driven it like that. Fortunately you did have an oil pressure gauge and thats what saved your motor from running out of oil. Fix the problem like dave said and it should be fine.

Did it really take 15 gallons of oil or quarts?

and to rotate the turbo you need to take the bolts out and pull the center section out the housing, you wont be able to spin it when its seated inside the housing.

My bad. On my Garrett and Turbonetics I just loosened and was able to make the changes. Anyway, it still needs to get done.

I can't take the bolts out at all, maybe 1. There being stoped by hitting the turbo. I called the guy that sold me the turbo and he said he had is oil lines hooked up the same way. That I just need to rotate the turbo cause with the return line is sideways, so oil is unable to drain back to the pan.

It's just getting it to rotate..lol There are 3 holes plus a line that looks like a small brake line. Two are pretty big which I was told is for the water. Another is shaped like triangles facing away from each other(best way I can descibe it) and the other is a brake looking line I'd say in about a foot long. Ill try and get some good close pics tomorrow in the day light and show u my setup.

The hole facing the radiator is the oil drain. This needs to be connected to the oil pan. The fitting straight accross from that is the feed line. The rest are water lines that should be capped off. Loosen the bolts as much as possible and tap the turbo out of the housing some. As it starts to separate you will be able to take the rest of the bolts out. Just be careful not to damage the wheels on the turbo when you take it apart and put it back together. Make sure there is no more oil leaking before you drive the car again

Any reason why my external WG was shooting out flames?

david-b · #70 02-16-2010, 11:46 AM

How did you dump the WG? Did you have it going back into the downpipe or dumping externally?

Its running externaly. I just bought the WG tube like 10 minutes ago. Could it just be raw exhaust burning out? Plus IM not sure the WG is doing its job. Every spring we put in I couldn't get over 3psi. They did send me some disks with the WG(pic below) guess its to stiffen the spring up more. BOV wont even go off.

Silver you were right about just tapping the turbo out. I did that it came right out. Got 3 of 4 bolt out. The 4th one if rounded off really bad. Just tryin to get it off now.

SilvrEclipse · #72 02-16-2010, 12:35 PM

Can you post some pics of the setup so we can see what's going on.. I thought you were running the internal wastegate. Did u block off that wastegate hole in the manifold

Cavalier9696 · #73 02-16-2010, 01:04 PM

I bought an external Obx. K i'll post some pics

Cavalier9696 · #74 02-16-2010, 01:16 PM

I think IM running to many vac lines. Would that cause problems? You can see on the Valve cover, burn marks from the WG.

david-b · #75 02-16-2010, 01:55 PM

Wait wait wait... you had the wastegate with no tube on it? Dude...

When you hit full boost that opens up and bypasses the exhaust around the turbo. No wonder you had a fire! Oil shooting out + fire from exhaust could have been a much worse then just a small fire!

I would have the BOV on it's own vacuum line. Did you adjust the Hard/soft on the BOV? You should be able to feel the air being blown out of it at idle when revving.

And what is the line running from the compressor toward the firewall?
