jeff thanks gain for more on our discussion. i will have to try to find some literature on the fuel cut im talking about but i like the 150 fuel cut you were talking about lol. Also good point on the 4 speed trans but i know with me when you got boost you always want more and everything factory on the car just really doesnt do justice anymore. Im sure you can agree with the 100%. Otherwise what your saying (which i should have read the whole thread) with the kits being 10% legal in just say the 50 states then yes. I will have to agree with your kit. I wish i lived a lil bit closer to you to mess around a lil bit more with the cars.

Hi Jeff, thanks for the explanation. I mixed up the OBDII plus testing and emissions testing. I find it kind of funny they check the plug for any errors, but skip the emissions test... In France, they do not do any visual checks. They lift the hood to check the chassis number but that's it. They also check emissions with a sniffer.
As for the cat, you could opt for a metallic cat. Wouldn't that hold up better on extended full throttle?

Certain states or cities with much more stringent emissions regulations require a sniffer in the tailpipe along with the plug in test. In these cases, of course a car with O2 simulators will pass the plug in test but definitely not the sniffer if you don't have a cat. You will lose a little power from having a cat in the pipe, but that's a small price to pay to stay fully legal. Also it's a small drop in the bucket when you have over 300rwhp(5hp loss w/cat) or 425rwhp(10hp loss w/cat) with Stage II.
Also, usually the metallic cats are not California OBDII compliant. They are high bypass catalytic converters(more exhaust gas is bypassed through the cat vs what is catalyzed). Yes it can withstand more heat and abuse, but there is a downside. It is only enough to pass loose emissions standards, but usually not enough to pass the more stringent ones unless you buy a really expensive metallic cat that is rated for OBDII emissions. I mean I can weld on whatever cat you want, but I'm just saying that if you use the cat I specified then it will be more likely to pass the sniffer compared to using a metallic cat. Or you can run without cats and find a shop that will pass you lol. Either way, the main point is that this kit will not throw any CEL whether if you have a cat on the car or not.
Really, it's all up to you

Awesome build! I wish it was easier to get hold of a 5-6spd tranny for a decent price.
With one of your kits installed, what do you think about driving the car in automanual? (2GS-up/down shift buttons on the steering wheel) I hate automatic transmissions with a passion.

With your stage 1/2, how will it perform in cold weather?
I live in Canada so it gets pretty cold in the winter time, around -30 C
Would this turbo setup still be reliable in such frigid temperatures?
I'm interested in stage 1/2 but worried about reliability in the winter.

For those of you wondering, yes I'm working on developing a turbo kit for this car. I still need to do some more testing and research, so I have not announced anything official yet. I'm waiting on a few things in line to be completed and I will become a vendor here on CL. Most of the things I'll be offering are hard to find items that you probably won't find anywhere or stuff that just doesn't exist for this car. My goal is to make a bolt on kit with all electronics + pre-tuned for the GS300 that will not set off any check engine lights and will still pass plug in OBD2 testing.
I'll need a few extra guinea pigs in the future

Still testing reliability. I've been flogging the hell out of the car all the time to do the testing. So far it hasn't had a single hiccup, it runs just like a factory boosted car.
It's actually a R&D car. For the sole purpose of developing a twin turbo kit
Sorry I'm most likely going to be moving onto a different platform soon, so I won't be making much more stuff for these cars in the future.
