How to hookup a turbo

I looked around for about 3 days, and i finally found out how to do this. This might seem like a pointless post, but i think it will cut down on a lot of the n00bie questions. I hvae altered a picture from Scale Speed Works owner to show where the piping should go. I realize some posts similar to this have been made, but they werent very clear, i thought, and i figured id make it really clear by doing this.

Hope this helps some people!

Description: Intake is what it sounds like, you can modify the integra intake in this case and attatch it to this point. Exhaust is refering to the down pipe, which would come normally for the headers, so you add a down pipe to this port, then run that to the exhausts. Intercooler is going to the right side of the intercooler (looking at the front), then from the left port of the intercooler, you run a pipe that hooks up to the manifold(where the stock intake hooked into) After that just add some details such as brackets and fasteners for a more realistic look. Once my integra is completely hooked up and painted i will be sure to post a picture for better reference.

EDIT: Please note that the exhuast and intercooler tags are reversed

To me that doesn't look right at all. This has been discussed before, so if you do a search of the forum, I'm sure you'll find a lot of information on how the turbocharger works and what various outlets/inlets are connected to.

your intercooler should be exhaust your exhaust should be intercooler and from the intercooler the intake connects to the other side of the intercooler and your intake labeled spot would have a pipe with a filter.

:slap:

ah well i tried, and i asked a few drifters and they seemed to agree. Delete this post then

you can yourself, go to edit/delete in the first post in this thread, select delete this post. and click delete and the thread will be gone.

how about i fix it i have a pic i can post right now.

Here's a better pic of how the system should look:

It's just a guide as car & truck makers design as they wish to accomodate for engine and chassis design.

Note also that there should be an air filter of some sort where in the pic it says "Ambient Air Inlet".

Note that the intercooler is always after the compressed air but before the cylinder intake (to cool the fuel/air mix). Think of an intercooler as an "in-line" device.

Also, you don't have to be pinned down to an intercooler design that looks like a radiator. My 1:1 '90 VW Corrado G60 had a cube-like intercooler tucked way in front of the left front wheel & under the battery.

OK well thanks for sending me off in the right direction. Ill keep so n00bs can find it if they search. pretty big if lol

Maybe you should edit your first post so the newbies don't get confused?

good idea, ill do that now

That re-labeled pic is much better!

You now see that you've pretty much mounted the turbo back to front as the air intake is more likely to come from the front (I'm assumimg your engine is meant for a front engine/rear wheel drive car).

Also, you could add a tubular exhaust flange (smaller in diameter than your turbo center section), a few (scale) inches long, to the exhaust snail. This is where the engine pipe would hook up (not always a gasket at this point because of extreme heat and a three-bolt flange is OK).

If you do that, you might as well tighten up the turbo center section a bit. All that it houses is a very small center shaft bearing (turning about 10x engine speed) and passages for oil and maybe water (coolant).

I had a question, isn't the wastegate supposed to be mounted on the cool air part of the turbo instead of the hot air (exhaust side)? Since then it would be leaking out exhaust in the engine bay... :confused:

Since the exhaust drives the turbo, the wategate is mounted there.

On street cars, it dumps exhaust directly to the exhaust rather than driving the turbo pinwheel. It cannot dump loud, raw exhaust into the engine compartment for lots of reasons. One of which is that it still has to go through the catalytic converterter to be cleaned up.

Wastegates always run off the exhaust turbine. External wastegates are obviously mounted externally off the turbine housing. Somewhere on an exhaust collector. Internal wastegates are the flap doors you see inside turbo next to the turbine. The internal wastegate opens via an actuator.

Here's a turbo with an internal wastegate. The circular valve to the left of the intake compressor in the first picture is the actuator. The actuator is connected to the circular flap (the internal wastegate) next to the turbine the second picture.

Here's an example of an external wastegate. Notice that the turbine housing doesn't have the flap. That's because the external wastegate controls boost.

Jaymes. After reading your post over again. Maybe you're confusing a wastegate with a blow-off valve. In which case, you are correct. The blow-off valve is mounted somewhere between the intake compressor outlet and the throttle body/intake manifold. Two totally different functions.

here1s how i do the turbo...it's correct...i think...

flw! see ya!

The engine in the pic is for an Integra though isn't it? I am sure that is how I read the original post.

Wow I am totally confused now, with all the pics and stuff....

thanks for the info guys. mrceej I was actually talking about the wastegate. Its function is to let out excess air while boosting right? And the blow off valve is to let off air when you let go of the pedal and don't need boost.

It's all so clear, now!

How about this picture then. Does it make things any clearer to the rest.

Most street cars with an external wastegate are not going to have a cat,and it would dump down by the fender.
