what kind of power do you guys think a gs300 would pull with this mods?
1. adjustable cam gears
2. camcom unit
3. headers
4. down pipe
5. cat back system
6. cold air intake
7. pulleys

lets say it also had a tc, vb and a lsd would it be faster than a stock gs400/430 ?

Gs300 is a vvti car so you can only use one cam gear on the exhaust cam.

Probably wont take a Gs400/430. You will most likely dyno in the neighborhood of 190-200 rwhp with a good tune. Gs400/430 usually are around 230-240whp. From a dig a TC is going to help the most out of everything (assuming you get a stall of at least 3200+ minimum).

Camcon is made by Power Enterprise and is a fuel and Vvti controller. Basically it's an afc that controls Vvti operation to a point as well.

Not sure what a Bv is though.

ok so its my afc on steriods Im running UR underdrive pulleys and you can feel the pull... the TC and LSD is CRAZY those should be the first 2 on your list... trust me break the piggy bank for that one...

i think with all those mods you might shave a second, maybe more on the 1/4.

I wish I knew where you could get an Lsd for $400 or a Torque convertor for $500. Hook me up with your connections man!

Lsd (Kaaz) if using your stock diff, is going to run you about $800. If you swap your diff for a Supra diff which is a bolt in you willbe looking about $1000 on the complete diff assembly but you will also being using the stock torsen Supra lsd, not a disk type such as the Kaaz. Don't forget labor, adds considerable $$$.

Torque convertor, you arent going to find it for under $800 shipped (assuming you use a PI) I contacted Lextreme and they wouldnt do a tc over about 3000 if I remember correctly(could have been 3200 but I think it was 3000) which is pretty much pointless on a Gs300. You will need a minimum of a 3200 stall and even that is a little low if your going for all out performance. Don't forget labor here, it's not cheap.

Pulleys (Greddy) $260 shipped

One (1)Exhaust cam gear (you can't use intake cam gear on a vvti equipped car) (Hks) $165 shipped

Power Enterprise CamCon unit $300 shipped
*Remember this HAS to be tuned on a dyno

Header (comes with "downpipe") $285 shipped

Valve Body $300
*Remember downtime and labor on this.

Rest of the items are in the neighborhood as listed in previous post.

dont waste your money on the bolt-ons. your list 1-7 will probably cost you around $2000 for 20 hp. and the TC, VB and LSD will cost you around $2500 for 1 second off your quartemile times. est. total around $4500


better off going with nitrous, 50-100 shot. $500-$1000, depending on the set up. or use the $4500 towards to turbo you gs300 or do the 2jz-gte vvti swap. but expect to dish out more $$$ if you do go turbo or do the swap. there are upgrades, tuning......etc...etc... involved.

Nitrous will be the best bang for the buck as always.

Outside of Nitrous, the biggest hitters on your list are:

1. Torque Convertor
2. Intake (only with proper fuel compensation)
3. Lsd (nice handling diff but not a huge diff in 1/4mi times)

I've already spent around $3.5K on my bolt-ons (parts and labor) and it's just like half of your list. Obvously I'm not as fast as GS4, but I can descently keep up with it up until 65-70MPH.
