Has anyone added any mods or boost their performance on their 4G GS 350? I'll like to get a few more horses running if possible. If so, how much did it cost?

This engine has been around for at least a decade and no one has made any mods that give significant performance gains. Could be the N/A nature of the engine or the "hard to crack" ECU. You're stuck with the usual upgrade of air intake and exhaust.

 

Somewhat curious as well. Not really concerned about more horsepower as much as I am about more torque.

 

One of the best ways to get more power out of your engine is by adding an exhaust which frees up restrictions and allows the car to breathe better! It also makes the car sound great!

How much power are you referring to? Will you feel it?

 

I have an AMG supercharger laying around....hmmmmmmm

 

The "F" in the F-Sport isn't enough for some, I guess.

That's why some folks are determined to getting a DINAN upgrade for their M Sport.

From past experience, I tried the K&N Filter upgrade for my 2001 740i Sport. Ended up screwing up my Mass Airflow Sensor.

 

The F Sport doesn't give you any more horsepower over the non-F Sport.

 

It's around 8-10 hp!

Get a nice prefab exhaust and drive it in Sport+/paddle shift with the windows down. The firmer shifts and suspension along with the exhaust when rev matching should satisfy you.

 

The 2gr-fse has very poor aftermarket support. If you are looking for easy power gains you may have bought the wrong car. Toyota and Lexus in general are not power mod friendly. Only things are cosmetic and minor bolt-ons.

 

Only the Supra was mod friendly, all Toyotas after that aren't.

 

And it turned into a money pit.

 

K&N should state cannot be used on German cars lol. Happened to my BMW also and swapped it out few minutes later it was fine. I been told that they come so oily from factory, proper way is to leave it out for few days before putting it in the car so all the excessive oil is dried up.
