Thought I'd toss in my S/C experience. I bolted mine on in March and I love it. Nothing incredible but I'm not digging in the low gears anymore. Which was a lot up here in the mountains.
2nd gen TRD supercharger with a big pulley (4-5lb max)
No 7th injector or ECU tune whatsoever. Perfectly safe with the low boost.
Runs smooth through entire RPM range. I can't wait to install my Flowmaster on my open exhaust so that I can here more S/C whine!

Here's a good write up for the 2nd gen DIY rebuild. I plan on following it one day.

Can you breifly discuss tuning options. I'm only familar with tuning for GM LS engines where tuners are using hp tuners or efi live. Would you essentially be doing the same? Finding someone experience with the Toyota 3.4 motor and f/i then they tune it via hp tuners or efi live? Or, do you have to use some sort of stand alone unit?

I'm not too informed on all the tuning options yet, but I will post my experience when I get there. I plan on just adding info to this thread as I find it. I'm not a sc expert at all, but felt the info needed to have one thread for others to look into. I just got back from a trip and will be updating the thread a bit this week with some more info.

no, you need a SC for a 3.4l motor from 95-2004

You mentioned in the original post...
"The TRD thermostat is a 160* and many people recommend running this ONLY if you do a very accurate tune and are trying for maximum performance. Be cautious with this one. You will often see the engine running around 175-180*."
I was just curious, why the need to be extra cautious with the low temp thermostat? Sorry, if it's a stupid question, I know just enough about motors to get by, is it really bad to run at lower temps?

It was me that said it, but potato potahto.
Its because the engine isnt in the optimal running temps at that low of temp range.
What's optimal?
I have water temp on my scangauge and once warm it is always dead nuts on 170F unless I have AC on (172-173F). Obviously this is just cruising around.
If I'm pulling up a steep hill I'll get into the 190F range.

I've had mine for 2 years, and its always been around 196-200* range. It can be cold or hot, its always within this range, even with the AC on. I haven't changed the thermostat since I bought it, so I can't tell you which one is in there...

Thanks guys! All the info here is amazingly helpful! I'm not looking to supercharge my 4Runner very soon, but I want to prep the runner for it and get some of the performance stuff done prior.
What is the best high flow cat I can get for my money. I'm going to pair it with a flowmaster 50 series muffler and definitely get the urd o2 adapter.

Anyone figure out something for the accelerator and transmission bracket? I bought a supercharger from a guy with an '01 so he had the different bracket on there and I don't want to pay $170 for one stupid little bracket.

They look to be pretty simple to make, but I'm pretty sure [MENTION=94888]EatonKyleH[/MENTION] has an extra one. I'd pm him in regards to it.
Congrats on the purchase! What gen did you get?

I just picked it up today. It has mostly everything except that bracket and then the parts that come with the dynamic tensioner so I'm gonna have to get that. He even gave me an '01-'02 throttle body with it so I can sell that and make some money back.
Oh and I now realize you asked what gen did I get. I read that real fast and read when did you get it. Haha. But I got the 2nd/4th gen black one.

It is a 2nd gen but its also called a 4th gen. I have no idea why.

4th gen is an Eaton designation. Only 3rd gen (grey called 1st gen by us) and 4th gen (black called 2nd gen by Us) were set up for use on the 3.4
