Hey Guys I just bought a 2004 Is300 and I will be picking it up in a week or two. Ive been trying to research things I can do to upgrade performance. I was thinking about adding a turbo to the GE or maybe swapping. If you guys can give me an idea on what to do to begin It would be highly appreciated. Also I want to be able to drift with it so if you can list good suspension kits and rims too. Thank you!

Welcome aboard. Believe it or not, those topics have been covered once or twice before.

Please browse thru the first couple pages of topics for the 1st gen IS and I think you'll learn a lot. From there, the forum can answer your specific questions.

Howdy!

Hodgdon is correct. It's all over the forum. Please post pictures of the car when you get it. I'd love to see it's progress.

Turbo will kill u.leavw it like that, a gs 300 03 model engine has another 20hp faster than the IS 300 2jz. Trust me I do speed my lexus,at 120 to 150mh,in already praying.but most times I rise from 0 to 100 n seconds,hard acceleration, more gas

The gs300 is rated at 220hp vs the is300’s 215hp. If you can count, that’s 5hp more. Not 20.

Story. Don't forget I have a big sport exhaust and cold air intake steel pipe which boosts my horsepower
