Twin Turbo 2011 4runner Help& QUESTIONS

i have a 2011 4runner 1grfe 4.0 mortor i wanted to do a twin turbo set up but need question on amount the stock injectiors can push with each turbo at 8psi how much pounds can the engine handle on stock internals Where i can locate the oil pressure sensor is at? Please help anyone

 

Go Buy a TRD supercharger if you want to boost a Toyota. Keep the twin turbo setups to cars with built motors that can handle it.

 

I like superchargers and all but im sure i can produce more power with the turbos that and i pretty much have them aLready lol honestly want to hear the choo choo sound

 

Completely custom set up is what ur looking at. Issue is no one seems to be able to hack the ecu completely

 

I think the guy you want to talk to is @Torspd. He's got a mad turbo setup on his taco and could answer many questions I'm sure.

 

Thank you Cory.

Like ForeRunner stated, your 4Runner's 1GR is of the dual VVT-I version. A little better flowing heads, but that is where it stops as being a better 1GR. Unfortunately, it is not the same architecture as the single VVT-I 1GR. It should have been named a different engine, but can't do a thing about that.

It has weaker internals than the single VVT-I (SVTI for short), and therefore cannot hold as much of boost from an F/I adder, psi - psi, as the SVTI. Gadget already encountered this as well. Despite still having a twin screw S/C on his 4Runner. His is running no more than 6 psi ( not sure the liter size of the blower, nor the volume of output) and had to have very careful tuning to keep the engine from failing.

Can you add boost from a twin setup? Yes. Must you be extremely careful on OEM internals? YES.

Adding rods and pistons alone would net you a huge safety margine, and allow you to achieve at least a 400 hp rating.

You'd still be left with a tuning solution necessary. Currently the only one availble for yours, which is a plug in play, is the UniChip. Unless you don't mind a wire in style?

Before I go any further.........what is the budget?

'Twer me, I would swap the SVTI engine in, used ecu, and harness, then go from there. I am not an average modder though.
