What To Do Next?

[axle13]

Hey guys,

I'm looking for your opinions/suggestions on what I should do next. I've got a 2001 IS300, with air intake, exhaust, and lowered suspension. The car rides nice, but I'm looking to get more power and don't want to spring big $$$ for a turbo.

Thanks in advance.
