    Question 2003 Tundra 4.7 Supercharger

    I have located a "brand new", in the box, TRD supercharger for my 2003 Tundra 4X4 Limited 4.7 (V8). I can get it installed by A Toyota Dealer for a total of $3,820.00. Is that a fair deal? Do they really make a huge difference compared to the personal upgrades I have done? I would put my Factory Air Intake box back on and omit the Throttle body spacer. I would keep the exhaust I have put together. Do you also need to run different plugs? Last of all, are they reliable? Thanks for any input on this.

    I ran the 4.7L S/C for over 2 years. I had NO problems at all from the S/C. I would get rid of the K&N and the Throttle spacer thingie as they will hinder not help with the S/C. Stock airbox and filter. The only downside, the S/C adds a 9th injector. So, your feeding 8 hungry mouths and cramming a 9th injector in there. You see where I am going.
    Also, your forced to run premium. If you run regular, it will only run for a short while, until the pre-detonation bores a hole in the piston. Just don't do it, run premium. Lastly, there are two choices, leave it 100% stock as in do not mess with the pulley, waste gate, fule system.... or.. if you alter one, then you need to beef up your tranny. It is an all or nothing sorta thing. The tranny was not ment for anything above what the S/C and TRD Piggyback supply. Ask around.

    I've had my 02 s/c on for 6 months with no probs. The extra poewer is perfect, only mod is air filter in stock box. Use IK 22 denso's and youll never have to change the plug up to about 120,000. If you want to be out in frount and way ahead of the pack of cars in trafic, climb hills with ease and pull with ease, then do it I paid 20 dollars less instaled by toy than your quate..its worth it..Also youll love the wine and sound at a stop light. Real attention getter.

    Thanks for the response. Greatly Appreciated. I see alot of threads saying there is problems with the s/c and you have eased my mind. I will use factory air box with the TRD performance filter. I have dual flowmaster delta series 50 mufflers. They are turned on their side and tack welded together. I believe it has 2 1/2" pipes. I believe that will be perfect with the S/C. It is to be installed Wed, next week.

    Regarding your tranny comments, my bro just bought a 00 4runner w/the s/c & noticed the tranny seemed sloppy vs my 96 4runner (2wd). He said it is making him nervous. From what you are saying the s/c puts a little stress on the tranny, correct?

    I can tell you from LIVING the nightmare the S/C WILL toast a tranny!
    I had a 1999 Toyota Tacoma PreRunner V6 blah blah blah...

    Had S/C Installed @ 28,000 and had the tranny rebuilt @ 64,000.
    Blown 2nd gear clutch pack. If he is having a "sloppy" shift now, then the fat lady is tuning up bro!

    Will the 03 Supercharger work on a 00-02 Tundra if you use the 00-02 Kit? Is the "kit" just a TRD ECU? OR is the 03 Supercharger a whole different monster. I read it has a 10th injector also. I don't want to waste time and money only to find out that it will not work.

    00'-02' campatible. The ECU for these won't control the 10th injector. If your gonna buy one, get the correct match. They come up on e-bay often. Some of us at great deals. About $2600 to $2800 I think is good. Some have done better and some have got ripped off. Do some homework and you won't be sorry. Good luck .

    I can get an ok deal on a 4.7 TRD Supercharger but it is for an 03 Tundra. However, I can get a 00-02 ECU kit separatley also. Will the dealer tell me they cannot install it because I need to have gotten a 00-02 Supercharger with the 00-02 ECU specific kit? Is the 10th injector something that is built into the 03 Supercharger or is it something that is optional and I'll end up having a spare injector?

    The '03 supercharger has two built-in injectors (Mototron 60 lb pico style) and the '02 has only one. The '03 ecu and harness are designed to handle the 10th injector as it has two injector connectors vice one for the '02. The 03 connectors on the TRD piggyback ecu will not fit the 00-02 Tundra ECU. Not sure if there is one injector driver or two on the '03, but on the '02you could run another injector connector from the single connector harness and run both the injectors from the one harness. The short answer is that the only difference between the 00-02 supercharger and the 03 and higher superchargers is the 10th injector. Other than that, they are physically the same. As far as running only one injector....TRD added another injector for a reason...I would not run it without both injectors. I can also talk about the transmission...I run a 4.7 and I had IPT mod my valve body before I went hot-rodding. Was running 8.20's in the eighth mile. I am finishing up a 650 hp 4.7 and sent the entire transmission back to IPT to build it so it will hold the torque...John told me the second gear frictions were getting really worn, so that seems to be the weak link. If you are only running the supercharger, I highly recommend sending your valve body to IPT and have them mod it....you will be greatly pleased at the results. Shift hesitation will be gone and increased line pressure is immediate when you stomp it...it will engage the clutches immediately and not let them slip as the stock programming will do. Hope this helps...

    I have an 02 tundra with the supercharger and i am havin a hell of a time trying to find a smaller pulley for the supercharger so if the 00-02 and 03 and newer superchargers r the same then will a smaller pulley off of a 03 and new supercharger fit my 02?

    Are you trying to gain more boost by changing the pulley size? If you pick up that 2 extra pounds of boost, you'll no dought introduce more issues. Thin sintered connecting rods will probably be the first to go. Another good option is an overdrive pulley for the crankshaft.
