ProjectGS#2: NA-T Build in 24 hours.
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

Can't wait!I'm down to be a guinea pig
Awesome work!
I highly recommend using an oil feed restrictor on your turbos to drastically prolong the life of the turbo and a SS braided return line. Anything else would melt or eventually crack since its under constant high heat. You might need an extra fitting depending on how you flex the SS hose.

If you check my first post in this thread, the blue hose in that picture on the drain line is what I use. Purosil multi layer reinforced silicone hose. Trust me, I have had enough trial and error in doing this stuff and I have all my bases covered
Thanks for asking though, most people don't even notice stuff like that.

Yeah, I said it will pass plug in OBD2 
I'm sure a inspector is more willing to let visual slide if the car has no check engine lights.
I'm working on some way to hide everything to make it look very OEM including use of the stock air box and snorkel. Piping will be powdercoated wrinkle black finish to look OEM and the intercooler coated in black as well. Thinking about including a catalytic converter in the exhaust piping as well. Then the car should pass both the sniffer and plug in obd2 test, just not the visual if the inspector knows what's going on

). You would probably need to include a cat on the down pipe for people in strict states. I never did replace my B-pipe with the Megan one, so I don't know if my 300 would pass with only 2 cats.I could only wish I lived in a free state.
I am pretty sure my GS300 only has 2 cats, those is on the headers. My downpipe has a resonator, but no cat (I have seen downpipes with cat though).
It passes smog just fine.
Sorry, was busy and did not remember to update this post lol. I've had the car running for 2 days now and driving around. I'll be posting updated pictures and some videos soon
