Post Cat turbo setup

[omni89LX-i]

This guy boosted a 94 cavalier by replaceing the muffler with the turbo setup. aside from that the car is stock, injectors and all. im thinking about tryin it for my 89 LX-i cuz my muffler is litterly rusted half off.

Has any1 ever tryd this?

Sounds like the Squire's Turbo Systems setup. There's lots of cars out there with this setup. It's proven reliable, so I don't see why it woudln't work. They sell a kit for about $2500 or so. I'd rather do this than a complicated setup with the turbo in the engine bay. You can ditch the intercooler, less heat in your engine bay, plus you can run long tube headers for more efficent flow back to the turbo.

[ZackieDarko]

you need lots of displacement to do a remote mount setup

this has already been coverd some where on the board

Id just do a real turbo setup.

i did a search of the site and found the thread that was already discussing this but around page 3 i got tired of reading and decide to just ask again.
my 3g is my daily driver, i love it, but a little more power (say 6lbs of boost) would b awsome!

i dont want to do a traditional setup because $$$ is something i dont have alot of. intercoolers, injectors, custom manifolds blah blah blah tend to add up!

[cubert]

Im looking at it like this...


A turbo is a turbo, either way more air is going into the engine, so regardless its gonna need more fuel etc. With low boost like you wanna do im sure the car would run etc, but i wouldnt really wanna take the chance of the car leaning out and melting a hole in a piston, ya know?

[omni89LX-i]

true
but if it does lean out and explode or something ill just do like Easy-E said and
"Throw it in tha gutta, then go buy anotha"
thank god for that salvage lincense!

I always wondered; How do they lubricate that setup? And what about the long piping you would need to run for the intake and pressure side of the turbo? dont hit a speed bump too fast.

Solution is easy: Longer oil lines. And why would the intake piping be any more at risk than your existing exhaust system? Make sure you don't have it hanging down, and you're good to go.

i had seen a guy here in town do that on a firebird. turned out pretty cool, but i think he killed the engine with a bad nitrous oxide setup. i think the remote turbo setup is a good one. keeps a lot less heat from transfering into the intake air and probably longer turbo life along with less internal engine damage from heat.

How would you run a return line to the oil pan when it is gravity fed, and the turbo sits lower than the pan.

Oil pressure.

Oil pressure.

That's what I was going to say... a pump. People do rear turbos all the time, the STS systems aren't magic.

So you would use somthing like a dry sump pump for return?

I don't know exactly, but I'm sure there's gotta be something out there. Or something can be modified to work. Maybe even purchase the oil pump from the STS guys, since they sell individual parts from their kits.

Here's one on a Cobalt, so you don't have to have big displacement for this to work:



The way I see it, if someone can design and sell a kit, you can build it yourself too.

Imagine how that fucker must sound! The turbo spool right at the back of the car, completely unmuffled! Would make some guys have second thoughts about racing for sure...

[mikes87lude]

WOW!!!! That actually looks pretty cool, bet it runs pretty cool too.(temperature wise)

[MessyHonda]

ewwww solid rear axle FTL

[mikes87lude]

ewwww solid rear axle FTL

The solid axle is pretty s@$tty. Bet it's pretty quick though, as long as you keep it in a straight line.

yup.....so that means my car could take that POS int the twisties...

A couple of informative links. These are Chevy setups, but they help to get the idea.

A buddy of mine had one on is Chevy pickup and it sounded like he had a whistle stuck in exhaust when he got on it.

[AccordEpicenter]

yeah itll work but the way i see it, its alot of added fab work, you gotta run charge piping ALL THE WAY TO THE REAR OF THE CAR as well as OIL LINES and then you need a scavenging pump for the oil drain because it sits lower than the oil level in the oil pan and will backflow into the turbo itself... Plus, ALL the factory exhaust from the engine back is a restriction at that point. I would only use a setup like this if there was absolutely no room to fit a turbo kit in the engine bay itself, other than that, i wouldnt reccomend it.

Wht about cost comparison?
Under hooh needs custom made manifold $400 to $700, intercooler $200 to $400.
Remote setup needs longer piping, Longer oil feed and return lines, 12 volt oil pump for oil return. (a Moroso dry sump pump like they use on V8 drag motors would probably work)

This is what I'm thinking. You're already running piping all over your car, from the turbo to the intercooler, then back up to your intake manifold. I'd bet the piping would be just as long, maybe a bit longer for the rear mount setup, but cheaper I bet than buying an intercooler.

And about the oil draining into the turbo... How is that a bad thing? Do you like the turbo draining oil out when you shut the car off? Seems to me it would be better for the oil to be sitting in the turbo at all times ready to go. Oil would always be in the turbo, and the pump would push the oil from the pan into the turbo, and that same pressure would push it back. I don't see how it matters if your turbo is below or above your oil pan, pressure is needed to circulate it, since it's still a closed system.

Also, who is going to be running a stock exhaust with a turbo anyways? And I don't see the added fabwork when you're talking about running a long ass pipe in a straight line. Sure there will be the initial bends coming out of the turbo, then up to the intake, but from the rear to the front of the car is straight, and may be even less fabwork bending tubes and whatnot. Plus you're spending a lot less time squeezing tubing around inside your engine bay.

And how much LESS fabwork is it than trying to make some crazy turbo manifold and cram your turbo up in front of the engine. Plus, I can keep my longtube header and get better flow to the turbo than I would with a log manifold, and at a much cheaper cost than a custom ramhorn manifold too. Plus you get the ninja-factor. Nobody will see the turbo when the hood is open.
