It is a problem to trying to intercool a s/c because you must cool the pressurized air, pressurized air on MOST s/c is located right after the throttle body. Its hard to try to intercool at that section because by the time you reroute everything thing you would have lost pressure and horses. Many companies have tried esp, with Hondas but the cost exceeds the benefits. Some intercooler kits ran up towards the 3000, just for the s/c intercooler kit. Turbo is a good route because it uses waste energy, the exhaust air, to pressurize the air. Turbo has no paradrastic drag on the motor like s/c. With the turbo technology these days, you could get pretty instant turbo response from a big snail, without the lag. Well, turbo does not usually have the instant torque that s/c has. I hope this kit will be mass market so the cost will go down. I have been waiting for a affordable priced turbo kit for the 3.4 motor, for a long while now.
The advantage to turbo is less polar inertia (lighter rotor) and no parasitic drag. |

That would indeed make intercooling difficult! Water injection...propane...nitrous....LOL

Ok am I missing something here?????????
From what I see of the estimated costs here for adding a SC. Couldn't you buy a whole motor from LC engineering with a SC or a Turbo and come in under the estimated prices? Then sell your old motor and cut the costs even further. This seems way to obvious. Let me know what I am missing. Thanks |

lol it was the V6 part I was missing. I have the 22re and I ASSUMED...everyone else did too.
I really gotta start reading things more carefully. Thanks for pointing out the obvious. : ) |

I know it is kind of off topic, but I was wondering how much it would be if I needed to purchase gaskets and all of the hardware that came with a supercharger. The only thing I would have is the supercharger itself, no belts or bolts. Any estimate would be very helpful, I may be able to score one cheap without the hardware and such. Thanks,

The more I see of turbo setups for the 3.4L, the more I am thinking that is how I will go on mine. They aren't quite as "bolt on" as a S/C but the tuning capability is just amazing. |
Hello everyone, This is Tom Cham from Hong Kong. I am new here & have just fitted the TRD s/c'r to my Toyota Prado It seems that most of the gas station in USA supply Octane 90 or 93 fuel. We use Octance 98 fuel in Hong Kong only. I am going to order a 2.2" s/c'r pulley & fuel upgrade kit from URD. Anyone here tried Octance 98 fuel in USA with 2.2" pulley & no fuel upgrade mod?
It was much more enjoyable to drive my Prado (very similar to 4Runner) with s/c'r and I would love to get a bit more :D Any recommendation will be greatly appreciated. :yotarock: |
Hi Tom -
The stock fuel pump needs to be upgraded no matter what. It is simply not up to the task of the increased fuel demands at sustained boost - especially if you plan on going to the 2.2 pulley. Furthermore, the timing problem (too much advancement in the stock map) between 2K and 3K (HG/LR) is not "solved" with fuel that can burn longer. Sure, pre-detonation will be reduced with 98, but you still need to install something that will take control of the timing, such as the SMT or FTC. I wouldn't even drive the vehicle without the Walbro 190 - even with 98 octane fuel. |
