Just curious what others have done to get the most horsepower out of their gs besides the old exhaust/intake solution. It would be great to get them in the upper 300's.

Nada. I've had dreams of shoehorning 5 liter from the ISF in there. If someone wants to sponsor me lol. Seriously though our only options right now are intake, exhaust, and headers.

Cheapest way would be to trade in your car. Done and done

lol. i gave up on the GS as far as getting more HPs. its a great daily, not fast but yet not slow.

Push the gas pedal to the floor?

Has anyone installed a nitrous kit on one of these motors yet?

I'd be shocked if they didn't, the basic guts of this mill have been around since 2006 right? Minus the direct clickety clack injection.

you can custom make a supercharger kit for the gs with low boost that could potentially give you 40-50hp, but that could cost some serious money really fast

One example of forced induction on a 2GR-FSE engine:

I saw today that Bullydog finally cracked Toyota's ECU on their pickups and SUV's. They've been able to get several more HP from those engines, so I wonder if it's possible that what they did can be done by other ECU tuners for cars like the GS.

I put in ppe headers and that was the only mod that made my car quick

yardie876

What kind of gains are you looking at with the headers?

GSTONY

Minimum of 10whp atleast, I also running a true dual with no cat and res with hks hi power cans. So it making abit more but its sounds like no regular gs

or you could trade in your current GS. buy a 2nd gen GS300 and throw a 2jz-gte motor in it.

I wanted to do this aswell as a project and still have my 4gs
