add those turbos
By Aaron J. Lexus on


2003 Lexus IS 300 4dr Sedan (3.0L 6cyl 5M)


The 5-speed is definitely the way to
go. Add aftermarket air induction, a
turbo, and a back-cat exhaust. This
alone will up the performance value to
a 10. I want to directly port a 50-
shot or 100-shot bottle of NOS on mine
for some real big horse power gains.
Some aftermarket turbos, although
reaching about $6,000, offer a boost
of up to 500 horse power! Improved
handling and a slammed stance can be
found in an AEM suspension system. I
would think that this car would have a
little more room in the cabin since it
is a sedan. And I've always liked 2
door coupes so much more. It's still
really phat for being a Lexus.

Best Features

I love the 5-speed. Butter doesn't even come close to the smoothness of the IS's transmission.

Worst Features

I know I wouldn't mind a 6-speed or a 2-door version. That would be hella cool.
