Well I sold my 03 IS300 5 yrs ago because of the cost to go turbo.

Found this one already done up.
04 Manual Trans 73K Sport design
Mods Include
Precision Turbo T66/T4
AEM Gauges include Air/Fuel, Boost, and Oil Pressure
AEM Piggyback (Seller told me it was standalone its not)
Full Exhaust system 3" Turbo Back
Piping intercooler, manifold all custom
Tial BOV
ACT Stage 3 Clutch
K-Sport coil-over suspension fully adjustable

Two of my favorite things combined with this car (turbocharged and Lexus), Still have some issues to deal with but Im hoping that the boosted community will help me out with learning.

Figured I'd throw my '02 IS in here.

Quick dyno pull video:

Running an EFR 7064 at ~15 PSI on VP C85 the car made 360WHP and 390WTQ uncorrected on a very low reading Mustang 1100SE. Bone stock the car made 150/150 on the same dyno.

SRT Stage 2.75/E-shift/15 PSI low boost to 19 PSI which hit 350/410 rwhp on a mustang dyno. It's a Precision T4/61 trim with I think a 50mm wastegate/Tial BOV/3" charge piping/4" intake pipe on turbo and a Turbo XS dual stage boost controller (hence the pairs of numbers relating to PSI/power.
Install/trouble-shooting with SRT kit (there was ALOT of it) at Central Import Authority in Nicholasville, KY. Tuning done at Dynosty in Louisville. I highly recommend talking to Hal at Dynosty for any technical questions/suggestions. Central Import is run by Erik T. He seems to know more about performance parts than most know about themselves.
Waiting on a KAAZ 1.5 way LSD to take it to the track next summer. Finally got the car done about a month ago...just in time for winter :-/
Time slips/pics/vids to follow once I get a chance to really run it when it gets warm again.
