what are the best performance mods for a 2006 tsx with an auto transmission?

 

Reflash or Kpro/Pulleys/CAI/Race Header

 

Lighter rims AND lighter tires will make a difference (or, at least, don't go the other way), and a 225/45-17 size tire will give slightly shorter gearing for better acceleration than the OEM size 215/50-17.

Try to confirm the weights with the manufacturer's info, and don't just rely on tirerack.com (although they are a good start).

 

If you have no budget, comptech supercharger with cold air intake, header, and exhaust for about $6000+labor to install:

S/C: $4000-$4400
Intake: $170
Header: $630
Exhaust: $1000

For that kind of money, you can upgrade to a RDX.

 

Buy my car...It's an 06 5AT and already boosted : ) J/K. The above posts are correct; pulleys are another good option.

 

check Marcus @ heeltoe fo the charger, he has the s/c for a bit less than $4,000-4,400

 

if you change the pulleys do you have to change the belts also?

 

^ Depends on the pulleys you get. UR yes, Ralco you can use OEM but it would be a tighter fit if you go with a smaller belt. Run a search, been addressed a few times. Only 1 belt to change also.

 

Hey man I did a bunch of research on performance mods for TSX's with 5at's. I personally have a 2005 5at (bought recently) and I just got my first engine mod which happens to be a CAI (seems to be a good base). After I install that I'm probably going to be looking at getting the Hondata Reflash or possibly some Unorthodox Racing pulley's, or a T1R Header. Check Heeltoe.com or even Ebay, thats where I've purchased a few of my mods so far. Good luck

 

how about the best mods for an 06 manual?
