performance chips

jus bought an IS not to long ago so im a newbie to the lexus mods... previously i owned a 328i and it seems to me that there is a endless amount of mods for bmw's compared to lexus' one question i have is do yall have anyone that makes performance chips for the IS i recently installed a JimConforti performance chip in my bimmer and it made quite a difference... what about pulleys? all i hear about on here is exhaust and CAI which doesn't seem to do much in the whole scheme of adding hp. please help thanks!

OK, hit up some old posts there johnny. There are an incredible amount of mods for the IS. You can do an HKS pulley. Chip wise get an S-AFCII or you can go with the standard and well-liked SRT Intake w/ Race-ECU. Rumored at about 22hp+ But I had this on my car at one time and couldn't tell that much.

Intake, axle back exhaust, header / race pipe, b-pipe, AFC, cam gear / pulley.

Try some of this.

www.swiftracing.com
www.pfsupercars.com
www.turboeast.com
www.toyomoto.com
www.powerhouseracing.com



Most IS people that want a serious kick in the pants go with F/I. There are a good dozen kits out there that are available from different mfr.s with various specs.

How much do you want to spend?

I think there are more things available for the is300 compared to the bmw...thats one of the reason i chose my is300 over a 325ci...i really never realized how many things, big and little, you can do to this car. Keep surfing this site and ull find out. Performance mods are somewhat limited of course but thats with every car, inside and outside there are 2x as many options than the bmw

If ur looking to spend the money to go fast go FI or u picked the wrong car to go fast with

Just so you dont get scammed there is NO performance chip for the IS300 you will see them on ebay but they do not work at all.

Best bet is getting headers, intake and muffler and having it tuned
