Hello,
I recently purchased a 2005 RX330. Its a beautiful vehicle. I'm looking for some assistance: I find it a little on power. I have already installed a Weaon R intake system and this is a healthy dose of power. However, I'm looking for some other suggestions. Has any one added a performance chip? If so any feedback would be great. Also I'm planing in an exhaust system upgrade.

Also, I'm looking for some fluid advice. I've already changed the oil to synthetic oil for the engine. I want to change the transmission, diff and transfer case fluid to synthetic. Can anyone recommend the following products as they are using them- Royal Purple, Lucas, Mobile 1.

Any advice would be greatly appreciated,
Chris

 

Might be able to find a supercharger for it from TRD.

 

Stick with the toyota atf. They have a Apexi axel back system for the RX. You should upgrade the whole piping at a quality muffler shop, If you want more mid-high range power.

 

ive been told 04 and up lexus' have toyota world standard ATF which is supposed to last the life of the vehicle unless your towing. Im still torn on this issue since I just bought my '07 and Im at 53K miles and i dont want to risk something bad happening...
