Hey guys I have a GS3 and just need more power. I am in high school and do not have much cash at all for FI. Maybe in the future but for sure not now. Are there any bolt on's to make this engine really jump? I know that GS3's are hard to squeaze power out of but what can I do that will make some noticable difference?

Thanks,
Elliott

Srt intake and 3.76 Lsd and torque converter.. and exhaust if you don't already have it.. i thought your car was modded already? Good luck..

Scratch off the 3.76LSD. It's only good for the GS4xx or with a 2jz-gte swap. Not the GS300

I know that the LSD is not a good idea on a GS3 but I thought that was the same with the TQ converter? Anyone have any idea?

Thanks,

I was also under this impression. Faster is great and all but for me, I am focusing on the pimping aspect of the car.

Elliott,

To be honest, until you can afford boost I wouldn't waste the money on performance mods. Like Lexbox said - go with cosmetics.

No point buying an intake b/c you will have to remove it to boost. I don't know how a TC is on a GS300 - but I know on my 400 that I love it. Can be expensive though after you factor in labor and $100+ of tranny fluid - cuz u gotta get the Amsoil

Get youself a TTE lip or save up for some wheels

Well, out of performance mods other than FI, I've done them all - SRT intake, Borla Exhaust, and PI Dragon TC, plus some suspension on my GS3. It's definitely not FI, but the car feels and moves much faster. At least now I don't have a problem beating cars like BMW 530, as was discussed in one of the posts of racing section here that stock GS3 can't beat.

The 3.76 gear ratio w/ LSD will actually make your SLOWER off the line since the GS300 already has a 3.9x rear end. You have no need for the LSD since you shouldn't have any traction issues at all.

A high stall torque converter should theortically help, but I believe the GS300 requires a different unit than the GS4. Not sure if it makes as big a difference on the GS3 as it does on the GS4.

I'd agree with most others here... concentrate on good maintenance of your car, detailing and keeping it clean and subtle improvements in looks. Until you get FI on a GS3 IMO you're wasting $$ with small incremental improvements that won't make much of a difference.

Yep I agree with the others. Maybe think about selling the GS300 then search for a good deal on a GS400.

The TC should help the GS300 although it will not be the same bang for the buck as the GS400. There is just more power potential in that V8. With the cost of the GS3 PI TC (~900) being greater than the GS4 (~700) and the gains is less than it is for the GS4, it is just not a great bang for the buck. Also, if you can get it installed for $100 + fluids, that is a GREAT price.

Anyway, at that pricing, the TC is still not a "cheap" mod but is still way cheaper than FI. I agree with the other, though, that it is the GS3 is just not set up for modest gains. If you don't like the power, you can:

1. Live with it (since it is a no additional cost option )
2. Sell it and get a GS4
3. Go FI

Anything else will just disappoint.

Neo,

I said labor and $100+ of tranny fluid Not labor of $100 That would be cheap huh!

Let's see... your in high school and want to go faster?
This will just get you more speeding tickets and a suspended license. Ask me how I know this.

Also, driving a pimp car will get you the ladies more easily than driving a fast car. Just a thought.

HAHA. My bad.

nobody recommended a $500 nitrous kit

Seriously though, A GS3 could take 75hp kit ok, no?

lalexusgs

You're right. Zex makes very discent kit's compatible with GS3. It just costs another $500 to install it unless you can do it yourself.
