For you guys who are thinking about puting an intake on your turbo, check this pic out from a Japanses site. As you can see, the only thing the intake really consists of is the piece of pipe( the silver part) joining the stock rubber elbow to the elbow going down to the turbo. This can be made by any local exhaust shop for only a few dollars. They can even put in the vacumn line fittings I'm sure(mine did). Then all you would need is the filter and adapter and you're set.

This set up definately smoothes out the air flow compared to the stock set-up. The only way mine differs from this is that my intake shoots straight out towards the fender, where his bends toward the front of the car where there is a bit more heat from the head. But just throw up a little shield or run a cold air tube( should have one anyway if you have an open intake anywhere in the engine compartment), and you're good to go. Just copy this picture and take it to the local exhaust shop and tell them that's what you want.

One thing I didn't think of is that this car doesn't have ABS, but it
almost looks like it would clear it if it did. If the ABS was a
problem, you can simply connect the MAF right to the intake pipe
using a rubber or silicone connector, and you're home free. In any
case, it gives you an idea of how simple an intake can be made for
these cars.

Hi

Call me stupid ( I'm used to it:) ) but I am not going to change my standard airfilter to under the hood k&N equivalant as I would prefure to have lag over early detonation and engine damage anyday.

Am I rational in my decision or do I need a kick up the bum

cheers

You need a kick up the "bum". Firstly, the engine compartment heat
does not get very high while driving, not compared to the actual
temperature of the air after it gets compressed by the turbo anyway.
After it sits a while after being driven hard, then yes, it gets a
bit high... until the car starts moving again.

Secondly, as I suggested in that same post, use a cold air tube with
any open air intake under the hood. Not because of detonation( a FEW
degrees warmer air on a turbo car will not cause detonation), but
simply because it's a good idea to get the coolest air possible into
the motor.

And Every single Legacy Turbo(any variation, including UK cars) and
early WRX motor I have seen, has the stock set-up that looks like
this: http://www.egroups.com/files/BC-BFLegac ... ncar11.jpg

The air has to make a very sharp 90 degree bend inside the air box
and then another right after it. The aftermarket intakes help smooth
things out a bit, which is desireable, especially on a turbo car,
which is why Subaru's intake is now a straight shot under the intake
manifold runners and into the turbo.

Hope this clears things up a bit.

Oww my bum hurts, but does having a k&N really make to much diff in hp and reducing lag? has anyone made this single mod and remember the diff and does it make loads more induction noise?

I've heard each 4degree rise in intake temp =1% loss in power

so at 200hp = 2 hp loss...... is it really worth it

cheers

For an NA engine you really should be concerned a lot about under-
"bonnet" temperatures, but with a turbocharged AND intercooled setup,
it's not quite as critical.

The temperature of the air under your hood is going to be hotter than
from the fender, that's for sure, but it's not going to make much
difference after it's been compressed by the turbo and forced toward
your intake manifold.

This is where your intercooler steps in, sucking that heat from the
intake charge. Sure, the charge MIGHT be hotter, but i honestly
doubt it would make much difference.

In an non-intercooled car like mine, and all "stock" USA-spec turbos,
a cold-air intake is prefferable because we don't have the luxury of
an intercooler to get rid of that extra heat.

I would really like to see a before and after with a stock box,
stock/intercooler, free-flow/intercooler temperature chart, but it
probably won't happen...

interesting picture.
my australian spec 1992 Liberty Turbo does not have the air/air intercooler
but water/air instead and i have no spark plug leads.
amazing how one company make so mary variations to one particular model in
different parts of the world.

Rod, if you are referring to this pic:
http://www.egroups.com/files/BC-BFLegac ... ncar11.jpg

That was an EJ20 that was installed in a US spec Legacy Turbo. I
believe Justin's motor did have the individual coil packs originally,
but seeing as how he used the stock EJ22T ECU, he had to retain the
single coil pack with the plug wires( correct me if I'm wrong
Justin). And since we were unlucky enough to have an intercooler with
our cars, he picked up an early WRX piece to go with the motor. I
think

Assuming that we are talking about K&N pod-syle filters, rather than K&N panel filters that fit in your standard airbox.... "Yes", a free flowing intake makes a big performance difference. IMO, it is the second highest priority mod after the exhaust.

Yes, they make "some" noise.

No, you get more than 2hp gain

You're exactly right, Matt. I kept the original coil setup from my
EJ22, just so I didn't have to rewire four individual coils (if it is
even possible to do so.) I also went with the air:air intercooler
because it's fairly simple. A front mount would be ideal, but even
the air:liquid in "normal" Legacy Turbo's is preferable to the
air:air in my opinion. Oh well.
