I want to turbo the 4Runner. I am ready to buy parts. It has been done before by a couple of guys. I would love CSi's help in selecting the proper turbo, acquiring parts, and giving any suggestions that would assist with installation.
This could be really fun. If you want to help just reply stating so. Rather than make a bunch of different posts every time I have a question, I thought I would just put everything into one thread.
Here is the background info:
-02 4Runner 3.4L V6
-Budget: $1500.
-Goals 250hp/300 tq with peak torque around 1500rpm.
-I don't mind buying some parts used if necessary
-Must be remote mounted
-Non intercooled, no meth for now.
I've owned several turbo 4 cylinders in the past, but I've never turbo'd an N/A vehicle.
The 3.4 has shown that it can handle 7psi reliably on the stock fueling settings/components and timing.
To give you a basic idea: 
The turbo and piping will be protected by a belly skid
Thoughts?

I dont see it happening at that budget unless you are building from scraps, but it could be fun regardless.
Goodluck with the build

What are you (or the other builds) doing for tuning?
Holset HY35 is a cheap option that will make the power you are looking for.

holsets are cheap. They're turbo diesel take-offs for cummins, I believe.
there's a lot of cheap turbos capable of movint the small amount of air needed for your goals.
Saab 15T is about the low-limit for 250hp, mitsubishi E3-16G/18g/20g,T28, Volvo 19T/K24, and a bunch of other take-off turbos could do it, but you'll need a relatively large turbo to move the amount of air you need @ such a low psi. T04E seems like a good choice, but I didn't think they were cheap-enough.
if it were me, I'd scoop up a used holset as suggested from ebay/or a junkyard, or start looking @ EvoIII 16G's before they price jump.

I can keep an eye on the Link forum classifieds for you if you settle on anything. I don't think an E316G would be all that efficient at 7 psi being such a small-frame turbo. Now a 20G? I could see that. Those can be found for around $400 if you want me to try and hunt one down. I also see Holsets quite often, mostly the HX35 variety which will be a little big I think - it's about the same frame as a Garrett GT30.
Stupid question, but have you thought about PM'ing denmah to see if he has anything sitting around that might work?

-Goals 250hp/300 tq with peak torque around 1500rpm.
Thoughts?
You can't simply pick and choose your HP/Torque numbers, or where they will occur...even with turbo charging (well, maybe with a monstrously missized turbo, but I digress....)
Essentially the powerband will stay the same, and the ratio of your HP to Torque numbers will stay the same as they are...the HP/TQ numbers will go up, sure...but you won't take a vehicle that makes 150hp/180ft-lbs tq to the rear wheels and suddenly get 200hp and 500ft-lbs of torch.
It's a general rule of thumb for turbo, and as such is meant as simply a guideline of what to expect, or what may be needed to obtain a given goal and gauge how realistic it might be to do so...but:
For every 14.7psi (1 bar) of boost, output increases by 100%. So a car that makes 100hp/125ft-lbs to the wheels now getting 14.7psi from an appropriately sized turbo, tuned correctly, etc, will now make 200hp/250ft-lbs of torque. The torque and power curves will look very similar, assuming you're making 14/7psi at the same rpm's. Likewise, at 29.4psi, that car will make 300hp and 375ft-lbs of torque, so on and so forth.
At 7.4psi, 150hp/187.5.
These are general numbers, not actually intended to be precise.
Now, are your numbers realistic? Sure, I guess...don't know what the stock 3.4's make to the wheels, don't care to look it up. But would you really get it to make the 300ft-lbs at 1500rpm? Nope...not a chance (though, you can through some dyno trickery, usually on an engine, not chasis dyno, get diesel like numbers by really restricting the rate that rpm increases, or loading the engine to reduce the rpm over the course of a pull).
Otherwise, it sounds like a fun project that could be done with some experienced guides checking in on you from time to time.

16Gs are internally gated at 13-15 psi, I don't know an exact figure for it. You'd probably have to go with an external, 38mm, to reduce boost to 7 psi. I'm not 100% sure on the 20G but I do know they can be internally gated. I don't know what a TD04E is comparable to. I found some things that say it's a .57 trim turbo but unless you know what family of turbos you're comparing it to, it's impossible to gauge. I would think something like a Garrett T28, Mitsu 18/20G would fit the bill. I've seen a lot of people shooting for low boost go with fairly large turbos due to how efficient they are at lower boost pressures. That's the opposite of, say a 16G which doesn't really hit it's stride until 15+ psi.

+1. Id be very impressed if you could limit boost to 7psi on an internal gate. Ive got an old t3super60 i ran with an internal gate. Lowest i could get ot of it was ~9.
The gates from any of the cheap option turbos from other oem applications will probably be useless for you
Id hunt for somthing external used. All of these parts you will need *can* be found from various forums around the interwebs.
Do you weld?

when i used a ko3 on my motorcycle internal gate dialed all the way back was 4psi
that is too small for this though...
you're goal is so low that i would say why even turbo?
a master power 70, .68ar is like 599, and will make approx 650rwhp
and on low boost will probably easily outflow your mafs on that car.
maybe you could get a used 20g or something like that, but man that is alot of backpressure probably
any turbo around 60mm will probably do what you want.

Why turbo? 230-250hp >>>>> 187hp 
Dude, you turbo everything, I can't believe you said "why turbo". My heart just broke a little.

i have a guy who i get turbos through.
vsracing.net
call him as his web stock is no where near what he can get you on the phone, if you call him (viren) tell him you know me and he will give you a discount for sure.
he stocks alot of 400-1000rwhp stuff though,
ide be willing to bet a mpt70 with the .68AR t4 tangenal will make plenty of power and stay very cool non intercooled under the car and with a 44mm gate from him for like 140 you can easily hit 2-3 psi to start.

Denmah, what brand turbo did you run on the truck? Was that a master power?
yeah i am in love with master power/magnum/borg warner turbos
viren stocks them all.
we are using a master power 76mm with a 1.0AR exhaust side, big mother on the truck. it doesnt light off well till about 3500 on 292cubic inches

is the 187hp crank numbers from the manufacturer?
ide say 100whp over stock on anything is doable.
so someone said there is room on the stock mafs and fuel system to make a few more ponies without modifying anything?

The tranny would be the least of my concerns at 18psi lol

Is your MAF in the intake filter area like it is on most Toyotas? In that case I think you'll want to recirculate the BOV. You can only vent a BOV when using a MAP sensor (speed density) or when you have a blow-through MAF like on GM setups.

*Looks at cacasesi's post*
"...money's that tight, a custom turbo is never a good idea."
*Looks at every post by Denmah*
*Attempts to wipe smile off face*
Yea. Gonna go ahead and disagree. Denmah isnt magic. If hes close by and his knowledge can be tapped, Id say why not have some fun slapping a turbo on it?
If it can be done, post pics, let us all enjoy and dream, thank Denmah, and romp on your new toy.
If it cant, post pics, let us all learn from your mistakes, thank Denmah, and then save up more money to do it up proper. Win win.
