Hi all....

I have a 2002 CL-S..A/T..56k...AEM CAI..soon to be installed underdrive pulleys...and im lookin for more hp...(arent we all?)...was wondering what the concensus is on upgrading the throttle body to get more hp??...Who makes them...cost....hp gain...etc etc???????...

Thank you all again...

Get an aftermarket header, you will be very happy with that upgrade.

TCM 01 CL-S

+1 for doing headers first. I don't know about the throttle body gains, so I can't give you any info on that, but there are some people on the forum with them.

I have a bored out S throttle body, not sure if it did anything but every bit helps when you are out of bolt ons.

you could probably get the throttle body from the new tl-s im sure it might be a little bigger since they re-did it..

Headers FTW. Far and away the best $$/HP you can do.

won't work.

new tl-s is drive by wire... the cl-s is on the cable.

The stock throttle body is pretty good sized. You may notice a bit better throttle response (although UDPs will give you much more) but your not gonna pickup much in the way of HP unless your running FI.

TripFontaine

unless you're running FI??..you mean...fuel injection????????

TheWeez

Forced Induction, aka, supercharger, turbo, or even NOS.

definitley do headers first and if you decide to do your TB i reccomend getting your TB bored out and getting bigger fuel injectors because the bored out TB will force more air into the piston and your gonna need the extra fuel to really feel any gains if any

Not really. On the CLS/TLS the stock ECU has some leeway when it comes to fuel. Unless your going FI there's no need to upgrade injectors, & still even then only if your running high boost.

Leave your TB alone, keep moving, nothing to see here...

TheWeez

Yeah there's much better stuff to spend your money on right now.

BigLizard

I say TB if you have every bolt on performance part on...sure...but leave it till last.

King motorsports has done the throttle body for a few guys on the forum but unless you have forced induction I'm not sure it will add much.
