I'm looking for the most efficient turbo to put on a 2AZ-FE (2.4L). It's supercharged now but I'm thinking of going turbo soon. I recall a while back someone was talking about compressor maps and determined a T3 Super 60 was the most efficient for a 1.8L (like the 7A-FE). Anyone know which is most efficient for the 2.4L?

Thanks in advance.

What spec is the SRT-4 turbo? That's a 2.4L motor.

its a mitsubishi td04 but i dunno the other specs.

It all depends of what you are going for really. How much HP you want. I know the SRT4 guys love the GT35R, which is a 500+whp turbo. If you are looking for something with crazy fast spool, get the GT3071 its a 350-400 whp turbo. If you want something in between, go with my favorite....The gt3076R 400-450whp turbo, and on that motor (2.4) I wouldn't think twice about it. But like I said earlier, it all depends on your goals.

TD04 is a good entry turbo. WRXes comes with with the TD04, and it's a decent power maker.

well what ever you do make sure to give me a price for the supercharger, my friend is getting his TC and wants that kit..
