Hi. I bought this car a few months back and really love it however, I really wanna increase the speed/acceleration of this car and I'm wondering if there's options.
Currently I'm considering headers/Intake/Exhaust and a tune(if possible). If I do this is it possible to gain significant power from this motor or is forced induction the way to go ....assuming that is even possible given how limited this car seems to be. This is my first car and I wanna make it special 🤣.

Honestly, I went through the same thing you’re going thru right now for a while, but learned that there’s really limited option for the 3GS gaining a lot of horsies other than the very expensive S/C or turbo route.
Some things I did that made the car “feel” faster:
-stickier tires (I currently have the Michelin PSAS 4S’s, I could feel the car gripping much better and launch slightly faster)
-new spark plugs, I feel like it had a placebo effect at first but I noticed some better pickup on freeway ramps maybe like 5-10% faster than old spark plugs
-thoroughly clean your intake manifold and TB, not 100% had the most noticeable difference but I think the car was running smoother for sure
-maybe an alignment could do wonders, I know it’s not a big improvement, but again the car is running in the most optimal fashion it can be in
Other:
-a Pedal Commander throttle controller (still have yet to try one of these but I’ve seen some reviews on other Lexus and they seem to make a difference on launches from dead stop in the different modes, I think Marty Motoring did a YouTube review on this recently too)
-exhaust would free up some congestion
-I use the F-Sport Air Intake Filter, idk how much difference that makes
ETC:
-I heard that the 4GS intake piping and sound generating hose fits on the 3GS (check CL post for how to do it) and it makes the car sound meaner during acceleration
Sorry if this list sounds basic or common, but it’s the best I could do personally to my own GS (2008 350 RWD, 115k miles)
