Hello people, I am noob at this racing world, but I want to find out what can I do to my RAV4 in order to add some HP and make it be respected on the street. It is a Second Gen. RAV4 engine is a 1AZ-FE 2.0 L 4WD If any of you have ideas, let me know, thanks.

The 1AZ-FE header/cat set up just looks like it would flow better and is obviously more expensive to make. When I did the swap, I kept the 1AZ header.

So my 1az motor blew out as previously mentioned and I got a call from the guy that re manufactures this motor and installs them (124engine.com). He told me that there's a shortage of 1az motors and that it would take a month to get one however the 2az motor is identical accept for the...
