Why would anyone add a CAI system to a turbocharged engine? They only
work for aspirated engines. For your set up you get absolutely no
gain
in hp or torque and it reduces the turbo life. The pressure
differential on the turbo is less causing it to operate at higher
rpm. The turbo winds up dumping all that extra air any how. Some even
say the CAI tube retunes the intake and makes for even more problems
for the turbo.

What good are those springs without changing the struts?


You're pretty much wrong on this. I've driven a LGT with these mods at
the differences are easy to note, especially on the suspension tweak.
The springs are designed to work with the stock struts. By the way,
the CAI is sold by Subaru for the LGT along with the heat shield. So
you're claiming Subaru is selling a part that will shorten turbo life
in the face of the long extended warranty they offer? No one, not even
the heavy modders seem to agree with you.
Most exhaust builders reccomend a stock CAI on turbocharged cars and I
will also be adding an exhaust.

You may wish to hire a suspension expert and go with a 16 setting
Takico strut system for your car. That may be the only way you will
see and understand a real difference. Visit a local track, have a
knowledgeable and experienced driver take you out to show you the
ropes. Playing race driver on public roads is dangerous and shows lack
of judgement on your part.

As far as your turbo goes, Subaru is famous for their undersized
turbos. If you could provide some real dyno numbers for your setup it
may then be a bit more objective. As far as turbo lifetime, as I said
Subaru is notorious for being undersized. In fact, "heavy modders"
replace the unit with one that is larger and higher quality. More
horsepower means more work and stress by the engine components
creating the horsepower. You don't get something for free.

The $200 bolt on kits that you are playing with does change the
performance of the car. There are subtle tradeoffs and you don't seem
to be aware of any.

As far as an exhaust system goes, the bottleneck is the turbo. You
will never get a correctly tuned exhaust system on that car. It would
be better to upgrade the turbo, upgrade the struts, wheels and tires.
There you may be looking at 10K worth of mods for some real
performance. Make sure you enjoy all that performance at the race
track, not amongst average/poor drivers on their daily commute to
work.

Bubbles' desire isn't on-road performance, Norm. He's only seeking bragging
rights, but I've trumped him with a Lotus Exige Sport, which is on order.
His Legacy may have slightly better straight-line performance, but it won't
stay with the Lotus in the track. And he can't stand it. g
