Parts
TRS Fab
I got hooked up with TRS Fab (Trent Stanley) back in 2014 when I first got my ATS. He hooked me up with a catch can,
air intake tube, Inter Cooler/Intake tube and a down pipe. I sold the CC setup as I was working on the RX CC.
So, I have the Inter Cooler/Intake tube, close to stock but metal, to test with 2.5L TB.
Note - TRS Fab is having issues so buyer beware.
JacFab
I got hooked with JacFab (Jason) when he first came out with the 3.6L TB & adapter. The first go around was the
TB, adapter and coupler to fit over the stock Inter Cooler/Intake tube. This work well according to my butt dyno.
Next he made up a proto-type Inter Cooler/Intake tube for me to test. Much cleaner setup.
Jason's Inter Cooler/Intake tube works with both the 2.5L & the 3.6L TB's. You just use a different coupler & clamps.
The only issue that pops up is P1101 on the 3.6L setup. This a MAF calculation issue. What is being calculated does
not match what is actually flowing thru MAF. The MAF needs to be recalibrated for the larger TB size.

3.6L Setup
ZZP Performance
Now if you want something different ZZP Performance & RPM Motorsports has 2.5L Kits.
The ZZP kit is a kludge and was rushed to market IMHO. I wouldn't touch it with a 10' pole.
$199 for the kit or $79 for the TB that you can get at Rock Auto for $70.
RPM Motorsports
RPM Motorsports kit at least looks professional and comes in 2 colors. At the time of this posting the cost was $199.
Me I am sticking with Jason. Top quality stuff and super vendor to work with.
