So this might be a dumb question but I heard I could install a super charger on my 02 without any fuel mods. I saw a video online that said our fuel systems can handle the TRD super charger.
I'm looking to do this maybe in the next few months but I don't really want to tackle the fuels system since the California emissions are pretty strict
Anyone know if this is true?

with a stock pulley and premium gas yes you should be ok. Though the fuel pressure regulator mod is an important thing to do also.

Check for vacuum leaks. Make sure you're not using a k&n filter, if so go back to a factory air cleaner and clean your maf.

Not dumb, it works just fine. I live in CA and as long as you print out the vacuum diagram for the supercharger to help out the smog tech all is good. If you can get the sticker as well (google it, you can buy it sometimes) that helps even more, if not go to the CARB (california air resource board) website and download the the EO and put it in your glove box.

What is the code number? Either you have a vacuum leak when you installed it or your O2 sensor decided to die on you.

Seems silly that I have to do 15 nonsense replies to get past the spam filter, but OK...
Soo much want on the supercharger. I have a '94 and always wanted one, bought wifey a '97 4runner and now just have to fix it up for her. Someday a supercharger will be in it.

What kind of regulator are you talking about

What sticker are you talking about? Wouldn't the sc come with it if I buy it brand new

It would, it's the EO# printed on the sticker. But be aware that the aftermarket version of the supercharger they make now (Toyota & TRD do not sell it anymore) may not come with one, since they have to jump through all the hoops to be CARB approved, even though it's the exact same one.
This is what the sticker looks like:

From Gadget's page about Fuel with the supercharger -
Fuel Delivery
While testing the Cartech FMU and the TRD Fuel pressure regulator I decided to see if I could run my 305cc injectors without an FMU stumbled across something. I removed the Cartech FMU and went for a test drive. I was surprised to see that my fuel pressure was increasing when I was in boost at a ratio of 1:1. How can this be?
I checked out my connections and found that I had the stock fuel pressure regulator (FPR) hooked to the boost port. The stock connection is to the main air induction tube which is really nothing more then a vent and gives a constant 43 PSI all the time.
With the FPR hooked to the boost port it will react to boost pressure and increase the fuel pressure under boost at a perfect 1:1 ratio. This offsets the boost pressure differential that I discussed earlier and really does a good job of stabilizing the fuel pressure in relation to manifold or boost pressure. The funny thing is that all the other fuel injected engines I have toyed with has the FPR connected to a port that allows it to read and adjust the fuel pressure in relation to engine load (manifold pressure).
Here is the benefit with the TRD supercharger. Like I explained earlier, as the manifold pressure increases in boost it will restrict fuel flow from the injectors. By reconnecting the FPR to the boost port you prevent this problem and it will give you 6-7 PSI of extra fuel pressure at max boost that you did not have before. Many people with the dreaded pining problem have tried this and it has in some cases eliminated the high gear, low RPM ping. All have reported an improvement.
I do not think for a second that this will be enough to prevent the fuel system from leaning out at max boost, but it will not be as bad.
Give it a try. It is FREE and you can easily switch it back. I have been told that TRD has heard about my little trick and is now recommending it as their own discovery.
I currently have my stock FPR connected to the boost port and I am using the 305 cc injectors.

Actually... They are approved as of December 9th...It would, it's the EO# printed on the sticker. But be aware that the aftermarket version of the supercharger they make now (Toyota & TRD do not sell it anymore) may not come with one, since they have to jump through all the hoops to be CARB approved, even though it's the exact same one.

Who wants to tune their truck with a much much better system than URD offers and is lazy? See below:

Want more features and even more tuneability because now that I'm out of school I'm gonna throw a smaller pullry on like idk a 2.0" lol something conservative ya know haha
It explains it in the discription
