Turbo Talk
If your looking into a good turbo. Garret or Precision turbos can be found used for pretty cheap. and rebuild kits are readily available.
If you are running remote, I would kill off the intercooler idea. thats a lot more pipe, and the charge is already cooling over the distance from the turbo to the TB.

Ok, I dont know sh** from shinola about these things, but just thinkin after i saw this pic, what would happen if ya ran the exhaust to the front of the bay, and put twins or even a single up there? ya you would have to have some custom headers made, but there would be enough room there to stick the things.

Great feedback guys that's exactly what I'm looking for. Ruger and tom, those links are great I'm already all over them.
Six shooter by rods I was reffering to the head studs.
Here is what I think about a turbo on our engine bay:
First of all if I was to put the turbine under the hood I would DEFINITELY go with a twin set up. why? Well just look at your engine bay, if you were to put one turbo then you would have to custom make a Y pipe that would bend from BOTH headers into one same side of the engine compartment. Then the turbo needs piping to breathe and flow pack into the engine. It would be extremely difficult to fit all this piping plus turbo unto one side of the hood. U will definitely be moving things around.
The remote set up allows for more room. Plus hey who doesn't appreciate a cooler bay compartment?
Sure there will be more lag. But hey the truck will definitely move faster.
I've checked out the STS kits and they are essentially what I'm trying to do on my truck, but are also heavily overpriced.

Plenty of V8 guys have done single turbo setups before. Honestly, single turbo configurations are much easier (hardware wise, and for diagnostics-trying to do a boost leak test on a twin turbo is a little more difficult). But, I'm not saying that a single setup is "better" than a twin. And...you don't need to move things around necessarily. If I indicate my preference, on any V-engine, twins are wonderful. Any inline engine should go with a single turbo. Again, based on years of racing, tuning, fabricating, etc, these are just MY preferences.
As far as remote turbo configurations go, the only gain you get is from having more room in the engine bay...thats it. Underhood temps will increase with the turbo or turbos under the hood. However, there are plenty of things you can do to keep them down. I'm not sure I would ever (on any vehicle) prefer a remote setup. Doing a boost leak test would be a f*cking nightmare, let alone having to rely on a scavanging pump to make sure the oil goes back in the pan.
Do yourself a favor, and start using the words, "simple, effective, safe". A bunch of STS owners will claim they don't have any oiling issues. Others will tell you that the scavanging pump failed, and now they are looking at a turbo re-build and an engine re-build. Awesome.
I have never had an oiling failure on the race car at the track or on the street. Keep in mind that making things more complex than they need to be will cause issues.
An electric oil pump failing should not call for a turbo or engine rebuild. You would immediately see smoke coming from the exhaust. Plus you can always install a pressure gauge on the oil return line.
Either way the pump fail its not "deadly" right away.
There are positives and negatives to either set up. But like I said if I did go for an in-bay set up, twin turbo would be the way to go and I just can't see the twin set up being less intensive or cheaper for that matter than a single remote turbo.

Oil going into a turbo, and not going out, at over 40psi will blow the turbos oil seal so fast, you would lose quarts of oil in a matter of minutes. not to mention the fact that oil will take the path of least resistance out of your motor, causing a pressure drop at the head and cylinders. The turbo needs a rebuild almost as soon as that pump fails.
If you dont get the motor killed quick enough, your looking at heads and pistons without oil.
If the turbo is still spooling, but blowing all that oil into your TB, your probably going to need a new IAT.
Hopefully the turbine doest seize up and send a fin into the intake manifold.
Your going to be running SUPER rich if your turbo dies and your running WOT.
I am not saying that you shouldnt run a remote setup. I looked into it. I had a lot of the parts on hand to do one. I chose to buy a turbo car instead.
In bay is the "safer" setup. you could still do a "remote type" setup, buy running exhaust back up into the engine bay and putting your turbo where your factory airbox is. you would need to fab up a mounting bracket to keep the turbo still, and then use the same exhaust flange that you would on the rear mount setup. this would allow you to feed the turbo from the block and return to the pan, without an electric pump.

Abnormally high oil pressure...everywhere, not just the centersection. By the time you see smoke coming from the exhaust, the damage is already done...to the turbo, at least. After many engine builds in my day, oil starvation is the most critical aspect of diagnosis and preperation.
