Looking to buy a 2006 LC this week.

What kind of performance upgrades are available?

Headers and exhaust?

I know the SC is out of the question for 2006-07 think.

Just looking for more HP than stock, as it is pretty dull:)

Googled around and didnt see much...

Thanks,
 
I'm interested in this as well, although I have an '01.

As I understand it, CAI and programmers are fairly worthless. I might do headers/exhaust down the road, but my mech advised me not to do SC without a rebuild, even at only 120k miles.
 
I came from a wonderful FJ62 with a 3FE, so yeah, comparatively, the 4.7L V8 is awesome..... but, it is in a 6000lb rig.....

Mine is also a 2006.

I don't know if the VVT is super tough to tune or why no one mentions doing much with the later models.

HFDPNL- Having owned and built several turbo and supercharged cars and more than 40 engines, I would say your mechanic is full of ....... stuff. Unless You are rebuilding with upgraded pistons with lower compression and better rods, You are just throwing money away rebuilding most Toyota engines at 120K miles.

My bet for my engine if I turbocharge it like I hope to, will be to install a water injection kit, run larger injectors, and because I am moving to Colorado, I may look into E85 fuel usage and a tune for E85 and one for premium fuel with water injection.

I have also looked into running some extra thick Cometic Head gaskets and some ARP head studs before I have any problems.




I just don't know if I want another daily driver hot rod..... I have had so many and truthfully, I wish there was an easy factory solution for this rig to add 100hp.....

TRD does a great job on most things, it is a shame that they did a band-aid on the 4.7TRD supercharger fuel and ecu.

There was a lot (!) of discussion several months ago about the headers - even some dyno sessions. Anyone remember what the gains are doing the headers, cat-back, etc. I like the idea of keeping the engine stock, but letting it breath a bit... unless the net is a neat sound and marginal gains.
 
While there may be some advantages to some of the normal channel upgrades, these rigs were never designed to be "sporty". You are pushing a lot of weight with a huge frontal area. The '06-'07 is better than prior years in the hp category. The more you add weight and lift the truck the more the acceleration is going to suffer.
 
I did headers and swapped the muffler (a mild one). The headers made a huge difference on my 2000. I use the LC around town mostly for my commute, so I also removed the jump seats and spare tire. I'd guess that saves about 150-180lbs. I'm hesitant to change the air filter/intake because I bet Toyota engineers put a good bit of thought into designing the stock intake for dust and water resistance.
 
EMS looks to be defunct currently though the store is up.

I'm the guy in fact that did all of the dyno work on DT Headers, EMS and DT exhaust... The headers are a good gain as well as the exhaust. If you go exhaust prepare for a very loud truck.

bottom line headers and open exhaust is good for +25 to 40 bhp and Torque.

I have the EMS midpipes with aftermarket catalytic converters on my 1998 LC and I have been very happy with them so far. The engine seems to "breathe" better and spin more freely after I replaced the stock catalytic converters with the EMS midpipes. I think the stock catalytic converters restrict the exhaust quite a bit, and the restriction probably increases as they age and soot builds up on the catalyst. I don't have any hard evidence for performance improvement, but my high-mileage 2UZ seems to run better and produce more power since I ditched the factory catalytic converters. The rest of my exhaust is stock, including the manifolds.
 
I guess it will be DT headers and Borla exhaust. They have a 2006 LC exhaust from what I can see online.
Just need to find a mid pipe like EMS Powered......
 
^ If "CA" in your signature means California ;) then know no CARB cert from DT for 2UZ-FE headers...don't believe their marketing/advertising!
 
Premium Fuel, Feed the car 93 -- and use PWR/ETC all the time. This ought to get you plenty of power on command. Yes this engine runs perfectly fine with regular 87 octane fuel. But 93 can make a difference. PWR/ETC also lets you access a bit more of the power the engine has to offer. I have 33" -- 275/75/r18 KM3s and no issues accellerating quick. Throw it into D4 with PWR/ETC and I can outrun any POS Hyundai or Shark Fin Shaped Car. I'm getting 13.9 mpg(mostly city) which is about the same as what my old 80 series used to get. No complaints with the power.

What are you guys doing to tune the engine for the change in AFR with the increased air flow? I know some folks don't think you need a tune but I've experienced quite the opposite on my other vehicles. I ran lean enough to melt/blow the electrodes off two of my spark plugs on my 6.2L Chevy. The increased airflow with the long tubes, full exhaust, and CAI were enough to throw warnings from my PCM saying the readings were going outside the bounds of the factory fuel tables to try to correct lean conditions.

This is an old thread, so not sure you'll get input from the original posters, but I think I can clarify a general point.

With most modern engine management systems they will self-regulate for the entirety of their programmed air/fuel table. Meaning, until you outflow the programmed tables, the ECU can accommodate the flow and will tell you when you're reaching beyond its limits.

If your Chevy gave you warnings it was outside the bounds that would have been your clue to stop and correct the issue. Normally, the ECU (PCM, whatever) will automatically pull spark or fuel or a combination so that you can't easily ruin a motor. If you tweak with the electronics or install mechanical parts that trick the factory electronics (modified air meter housing, for instance), then you're liable to lose the factory safeguards.

In this vehicle (non-VVTi, at least), the headers and exhaust made a surprisingly large power gain. That may not apply with the VVTi motors.
 
Mine is an 03 so no variable valve timing. I am getting ready to pull the trigger on a DT cat back this week. I would love to get the headers to go with it but the lack of tuning support makes me cautious to do so.
 
I know this is an old thread, but I haven't seen it mentioned yet, so here goes.

There is talks from Trail Tailor building a remote mount turbo kit for the 100 series. I'm not sure how much info I can release, but if you're interested, I suggest emailing them.

There is also someone on the Facebook group "Land Cruiser/LX470 100 series USA" that had polled interest for Magnuson to bring back the supercharger kit. However, there is no info on this and probably won't until November. Even then I'm not exactly sure if this will go through. I'm including a screenshot of the beginning of the topic for those who want to follow it.

Yes, it's on old thread. But with insights like this...

... we can't lose it to the archives.
