Do these not work on a 2013 Limited? I sure would like to have these units on my rig...

Uh, stoich is still stoich. Supercharging doesn't change that value when the fuel is the same. (the difference in stoich from 87 to 91 or 93 octane is negligible) You are right when you say that injectors and fuel pumps need analysis because you need to ensure you keep adequate fuel pressure...

Some of us just wanted a proper section width and sidewall look, so we kept the 20" wheels. Hell, I put 9" wide wheels on there with 275/55/20 tires and I have yet to throw a gang sign.. I know the 4Runner is great off road, I've taken this heap off road with my "bling" wheels. It did just...

You *do not* have to go out of state to get a 4Runner optioned with "out of region" preferences. All you need is a dealer that isn't full of crap and a deposit. I ordered my 2013 LE with retractable running boards, which are a non-regional preference in my area. I waited just shy of 2 months...

That's what happens when people don't pay attention in school. That same line of thinking reared its ugly head a few years ago when people went around saying that cell phones would ignite gasoline while refueling. :| Then again, I don't go to the gas station and expect the guy behind the...

PM'd you on the 4th. If you still have these, I am in fact here in Seattle. Give me a shout

No, engine braking is just that: braking. It uses the resistance of the engine to decelerate instead of, or in addition to, wheel brakes. The ECU is smart though, it won't let you downshift to a gear where the RPMs would be too high. You hear the little "beep beep" warning if you try that...

Heh, well, water injection is real enough, and it can be beneficial in some circumstances. Engines have used water injection for various high power application such as fighter engines. GM even had water injection for cars for a while (the dash in my 86 Buick still had a "water injection" place...

I didn't say that was the only reason. It *is* a primary benefit though, and it keeps you from having to do things like add a larger stall converter to an automatic transmission, etc. It's easier to spool two smaller turbos than one larger one. It's a balancing act between keeping hot air...

Explain to me how I am an idiot. Feel free to use actual math, science, or engineering to back up what you're talking about, because I have that data. I've made ~1200 hp on a single turbo, and I spent about 2 years getting to that point. I worked with SWRI to get there. How about you? Also...

I think what people are seeing is that these running boards are often not what is within a sales regions "preference" for options packages. You *can* get these ordered on a car, the dealer just has to know how to do it. I waited 2 months for my car because I wanted the Limited, fully loaded...

My guess? Because it would require more modifications, be more expensive, and is more interesting to tune than this setup. For example, a single turbo would need a crossover from one manifold to the other to feed the turbo with exhaust gases. Twin turbos, usually, have one turbo and one...

I don't know where you get the "they don't sell" idea from, because Toyota can't keep 4-Runner's on the lot in many areas. Are they as popular as they once were? No, but look at what has gone on in the last 10 years. People were given tax credits to buy Hybrids. Good stuff right? Well, what...

I would steer clear of any "universal" system. For starters, if it used the stock exhaust, how do they solve the wastegate/crossover problem if a single turbo is used? Where do they mount the Turbo? In most cases, you'll want a wideband setup to handle A/F ratio inputs and add/trim fuel...

They are tuning for rich side of peak in both power and fuel curves. The larger injectors will accommodate the higher lb/hr needed at each nozzle for the A/F ratio to be ok. They'll run rich of stoich of course... They won't run aggressive timing because of the cylinder pressure. Something...
