I am going to try and be professional and not point fingers...heh
My buddy who is doing the fab work for this kit is installing a new version of this kit on his tundra this week.
The sc will now be located on the passenger side and will not require tubing to cross over the manifold like the previous version. In order to fit the sc on the passenger side, we will need to replaced the factory airbox.

Well I registered on your buddy's site. I was told I was nuts by a friend as she said I'd loose any and all efficency for gas mileage, but I soooooo want one! I'm a firm beliver in that saying "When you turn your car on, does it return the favor?" lolblink said:I am going to try and be professional and not point fingers...heh

Gas efficiency depends on how often you want to go into boost. Right now I average about 19mpg with mixed city/highway driving.
When I drive it hard I end up at around 15-16mpg... Its not great by any means, but its not too bad of a trade off imho.
My buddies 5.9 RT Durango gets 6-7mpg with spirited driving...lol

Setup looks really solid! I like the fact that you are using a Rotrex 'charger - Those are really nice units. One question - why are you still running the stock airbox? Do you have a different filter in there?
Looks like you could remove the high pressure pipe going over the intake manifold (before it makes the bend into the throttle body) and replace it with an upfacing air-to-air intercooler. Then all you'd have to do is open the hood scoop (providing you have an SE or an SE hood). That would be money. If you're not running more than 6psi it probably wouldn't matter though. Just an idea.
I love the setup and if I still had the 4Runner the Rotrex would be the path I would've taken...

This kit use the stock airbox to retain stock driveability while not in boost. Im sure it doesnt matter much but Im currently running the TRD filter.
Ive contemplated running a top mount IC since i have a scoop with the insert removed, but ultimately I decide against doing a top mount and here is why: When I was NA and had the scoop open, I could visually see the heat waves coming out of the scoop when I was stopped. The cost of having a TMIC and having that much heat coming through it was not worth the return.
Thanks for the compliments on the kit

Compatability question.
I have 90K miles already and I'm concerned about what this additional compression might do. Engine,transmission,transfer case ,full time 4x4 systems, etc...
I want the power but, with an acceptable level of associated accellerated damage.
Would you reccomend installation on a 2003 V8 Sport (full time 4x4) with 90,000 miles on it ?
I'd like to hear from anyone with a reasonable opinion.

Compression wise, your 03 is better off for force induction, as the non-vvti engines have a compression ratio of 9.6:1 as opposed to my 2005's 10:1.
The 4-speed auto will need to have the valve body upgraded or shimmed in order to handle the additional power.
I think at 90k you are fine to run a s/c kit as long as you keep boost low(6-7 psi), and take care of your truck.
My buddy installed this kit on his 01 Tundra (same engine and mileage as you) at 90k and has run it to about 140k miles without any problems. Ive personally run the kit for 20k miles in 110F+ weather (Arizona) and have not encountered any problems (other than traction issues

Thank you for your promp and informative response.
"The 4-speed auto will need to have the valve body upgraded or shimmed in order to handle the additional power."
Could you expand on this?
Is this somthing you learned first hand?
Is there a valvebody upgrade kit available?
or where are shims required and at what thickness?
I'm (Sidewalk Engineer) hungry for details.

When I decided to supercharge my truck, I spent a good amount of time researching the TRD s/c kit, to learn from the problems they had.
I had found out that alot of people were having transmission failure due to the added power. This was later confirmed at Sema 07' by Magnuson Superchargers (manufacture the trd sc).
Personally I have not experienced any problems with the 5-speed transmission, but I took a proactive approach and did the following:
1. I replaced the stock tranny cooler with a much larger one rated for 30,000 pounds
2. Inside the transmission there are a set of accumulators that take the "shock" between gear changes. The accumulators in most vehicles are set to soft to allow for a smoother shift. For the average consumer a soft shift is preferred, but generates more heat. A large portion of a transmissions life span is determined on how cool you can keep the fluid. I added washers to the accumulators to provide for a much quicker shift, in turn reducing heat
There are a few companies that I know of that offer a service where they modify the valve body to achieve firmer shifts for about 600+ dollars.

i was under the impression, all 4th gen V8 4Runners had the 5spd trans? My 03 Limited has the 5spd.
