Ok plenty of room where though. I have the SR5 LE with all the trimmings under the bonnet .
As for the small block you cant ever go far wrong when its got 8 slugs !!!!

[kingmick]

you can go wrong if it has made by FORD on it

when i start ill take pics for yu to show you.

Hey the blue oval team gets somethings right but not in this country thats for sure.

Hey you ever race at Wakefield?

[30psi 4agte]

you a sick puppy putting ford an toyota in the same post!

fark what does that make me then lol. I have a Ford with a toyota in it!

[kingmick]

heheheheh very sick puppy! dont talk to me again! hehehehe just kidding

Yes many times but never in a Runner

[ToyMota 4Runner]

ever see some idiot running round after the feild at the start of races in a Runner ?

[ToyMota 4Runner]

<------------- same idiot !!!!!

[kingmick]

I prob have but cant think of it im usually thinking of other things at the track.
I will take note next time and say HI.

[ToyMota 4Runner]

No worries
am part of the team that does Recovery and Fire on the track for most meetings and I do chase recovery so if anyone breaks on the start line we can get them safe as quick as we can . We also tow cars back into the pits if they break in the Qualification sessions
Does the SC14 have to be mounted vertically or it doesnt matter?
Another blower to maybe consider is the units they ran on the V6 commodores. Just so happens I have one of those tucked away too .

[Toysrme]

If you want a blower, M62-M90 sized would be great. M62 would be more than enough on that SOHC engine, It runs outta breath pretty quickly. (The SC14 is in between an Eaton M62 & M90)
For all the effort to put a blower on that engine, I'd scrap the idea & go with a turbo.
Easy enough with the layout. Just afew welds.




I will say that unlike these guys, I would very STRONGLY advise you to blow THROUGH the AFM. (AFM after S/C, or turbo, whatever you do) You'll gain lots of response, you'll have less re-tuning to do, and the ECU will stay much happier knowing the actual air temp, and air mass running through the engine.


Which is something the first guy figured out & wound up doing anyways.

[ToyMota 4Runner]

Not sure I like the way he has made the Turbo Manifold but hey if it works. I have already split my exhaust so would a Turbo still work on the fumes from only the single side of the engine.
This also is for fairly serious boost on the poor old 3VZ motor. I am only looking for a small increase in torque not a race engine so to speak. I know that the poor 3VZ motor is never going to be a fire breathing beast however I am hoping that in its stock form it will handle a little boost to up the grunt factor a bit not a lot.
I am still sorta keen on putting in a rear mount turbo as it will be minimal impact and means no manifolds etc just some pipework and a oil lines.Guys in the states are using this means to boost cars that have crowded engine bays like Mustangs and such like.
My idea is to rear mount the turbo and then run the air discharge pipe back into the factory airbox . That way no mods needed to the factory intake etc.
However that being said I know people will say major lag times etc but not thinking going to be an issue. I do however need someone to point me in the right direction as to where oil lines would run to and from on the engine. Not having ever played with Turbo's before havent any idea what goes where with them ...

[JetspeedCamry]

Is that turbo only being driven off one bank?

[Toysrme]

No, the sohc 3vz-e's, like your 2vz-fe use a crossover pipe.
ToyMota 4Runner you could do it off one bank if you wanted too. You could also weld an up pipe & re-merge in the engine bay.


You've stated several times you don't wnt a race truck. So don't race it LoL!
A small increase in torque would be management, port & polish, unshrouded valves, larger valves & weasy's cams.
For the same money (If not less) you could turbo that & make 200-240bhp before you're at the limit of the stock fuel system. (Assuming a descent pump swap & fuel pressure were set correctly.)
150 bhp to 200-240 will give a good increase in torque & nobody's making u run that much power either.

3vz-e + A/T =

[ToyMota 4Runner]

well that certainly sounds like what am after. The only reason I say not a "Race Truck" is its the only way i can put it so I get across the fact I dont want to go too far as far as power goes.
Main reason being is that have read so many articles where bodies are saying that too much huff into the 3VZE will cause problems with the heads. I certainly dont want that to happen.

Squire Turbo Systems from the US is doing lots of work for Rear Mount or Remote Mount and this is some blurb from their page

* Ease of installation. STS turbo systems can be installed in about 8 hours with standard tools and average mechanical ability.
* Performance Sound. The turbo acts as a muffler and sounds like an aftermarket performance muffler. Turbo spool and rushing air from the blow-off valve make a unique sound that will turn heads!
* No need for major modifications to your vehicle. STS systems are designed to "bolt-on" to factory mounts.
* Increased gas mileage. Unlike a belt driven supercharger, the turbo utilizes "wasted" energy leaving your tailpipe. Most of our customers get 1-3 mpg increase in gas mileage.
* Lower underhood temperatures. No need to worry about melting wires, hoses, or other components.
* Converts back to stock in about an hour.
* More room under the hood. Future repair work or modifications will not require the expense of removing the turbo system to allow access to engine components.
* Cooler oil to the turbo. Cool oil is better for both the turbo and engine.
* Approximately 500F lower turbo temperatures. Eliminates the need for a turbo-timer, which allows the engine to run after the car is shut off in order to cool down the turbo and prevent oil and bearing damage.
* Denser exhaust gasses drive the turbo turbine wheel more efficiently.
* Built-in intercooling. Intake piping provides ~50% intercooler efficiency. There is no need for the expense, pressure drop, and installation problems associated with a front mounted intercooler.
* Turbo is exposed to ambient air rather than underhood air. Allows for better cooling of turbo components.
* No need for expensive headers, mufflers, or exhaust systems.
* Turbo is closer to the tail pipe outlet. Provides a better pressure differential across the turbine wheel which promotes better flow across turbine.
* Better weight transfer. Increases traction because the bulk of system is mounted in rear of vehicle rather than up front.
* Less noise in the passenger compartment.

might drop them a line and see what the go is
