Can this be done on a 3.0 ? :think:
I have a 1991 4runner 4x4 3.slow
I was wondering if something similar to this could be done ?

If you're asking whether or not the 3.o can be supercharged..., the answer is "yes".
If you're asking whether or not the "Gator" system would work..., I can give no input without further information of the system's application.

Thank you for your input. I will be trying something similar because of it simplicity. Also I was watching trucks on TNT TV and saw a turbo system the was mounted and ran of the tail pipe behind the muffler, sound great but not practical of road. Or the fact I live in the rust belt. LOL
I work for a crane company and have access to a full machine shop, that will help.
Will post my findings when and if I get it done.

Limiting the boost properly (and smoothly) is probably the hardest hurdle for the home builder. Then there's reliability - longevity of the components (bearings etc.) And of course managing the fuel mixture.

I don’t know that much about them yet as I have not read many books on turbo yet. But isn’t that the blow of valve job? as far as reliability of parts, I will use a constant oil bath for the bearing case and turbo. That is the plan for now but we will see after I have read up on turbo’s.

DUDE! You work for "Crane", as in "Crane cams"???? WTF?!?
"B&M" has a pretty cool side draft setup that would readily fit under the hood and hook up without all of that much modding..., unless you're into building one yourself.

We build in door cranes. Like bridge cranes and jib cranes www.contrxcranes.com

To run the turbo at sufficient speeds to produce boost, you'd have to really step up the RPM's coming off the crank to something like 10,000 RPM's or more.
Save your money, drive slow, live long, have children, prosper.

Secondly, you see stepping the crank's RPM's up to at least 10,000 as being an issue??? Inasmuch as 2003mikem does work for a crane manufacturer, lifting that is, I'll bet that he's already got an inside track on stepping up the RPM's..., can you say "reduction gearing"???

Well as far as the rpm, I don’t know a thing. If re gearing is an issue I can fab a gear box.
As I understand a turbo charger is driven by the exhaust. A super charger is driven by a belt or so on. In the link it shows a turbo driven by a belt. which would be called a super charger. Maybe, Maybe not. My thought is this is less complicated than reengineering the wheel since there is almost no room under the hood. As long as I can get a belt to drive it.I have seen turbo’s on 1 -2 4runners with the 3.0 but I would like something a little less complicated. Maybe it inst less complicated.
Once again I do not know a lot about turbo”s or superchargers. Just enough to want to attempt something or possible make a big mess of my 4unner.
p.s. if it matter it is rebuilt .30 over new cams pistons rods etc.

105,000 - 200,000 rpm pending the compressor wheel used...

Yeah, what he said!
Seriously though, that's a "supercharger" setup in the link and their application is considerably simpler than a "turbocharger" in that you can almost readily bolt on a pulley driven supercharger whereas with a turbo you've alot of plumbing and tuning boost parameters that you'd have to go through.
Admittedly though, the one major drawback to charger usage over turbo usage is that the charger relies on the engine itself to create "boost" or increase compression by slaving itself to the engine's crank pulley which has a tendency to create a drag on the engine, whereas the turbo relies on the waste product of the engine, i.e. the exhaust, to create "boost" and so, puts a way less, if any, drag on the engine itself.

Take a look at the eBay pic...it's the compressor portion of a turbo with a box mounted to contain the drive shaft. Finally a pulley is mounted drive the compressor. If, as Bumpin' says, you have to run 100K rpms, you have to multiply your crank rpms about 400 times. Not quite sure how you'd do it or how long a stock pulley would last before the vibrations killed it and the bearings.

"Paxton" incorporates alot of centrifical gearing in their applications..., just think "block and tackle" to get a visualization of what's involved.
