Got boost?

Haven't really looked before, but stumbled across a thrid-party Lexus tweaker. They've got a blower kit for the 1UZ (car version.)

They also talk about replacing the bottom-end with the current 4.7L block.

AND..... they talk about the 'new' Lexus-Toyota 5.5L V-8 coming out.


Should make for some interesting reading...... http://www.lextreme.com/1uzdesktop.htm

It can be done. How fast can you afford to go, Derek?

About 42, but hey, can't a guy dream a little?

If I won the lotto today, I'd keep the boat but I'd clearly be down with having it souped.

Gordy, I read on Lextreme that the Eaton M90 is the way to go. The site and forum has a ton of info about forced induction, but I'm clueless and haven't read through it all yet.

1) Are all 1UZs computer-controlled?

2) Do you have to edit the computer or its programming when you put a blower on it? If so, there'd be additional issue for us since I'd be real surpised if our programming matches the ones on the road.

3) With the moderate/conservative boost that an M90 would give, the injectors and fuel pumps wouldn't have to be changed, would they?

4) The TRD blower for the Sequoia/Tundra 4.7L is an M90, right? I also thought that it included an extra component in either the fuel delivery system or control system (CPU) to alter fuel flow and some other stuff. Am I trippin?

5) Do you think that MAYBE the TRD blower for the 4.7's would work on the 4.0's??? There is talk on the site about mixing 4.7L blocks with 4.0L heads, etc. If heads align with blocks, might 4.7L intake manifolds match up with 4.0L heads? Could it be that the TRD blower might need just a little shave on each side to account for the 4.0's shorter span? If the TRD blower package could be made to fit (like with just a little shave), it might be the cleanest (if not least expensive) approach. Plus we'd get a sweet TRD logo under there ;-)

6) Besides mechanical issues of mounting, fuel flow problems of going higher than moderate boost, and too-high compression problems associated with big boost, what other impacts does adding a blower cause?

Just for anybody else who might still be reading, the TRD blower package for the Sequoia/Tundra is so friggin clean you can do it yourself. And just so you know, if you have the toyota dealer install your new blower on your new truck, the original Toyota warranty terms are un-affected. In other words, over a 3yr/36,000m interval (and longer with an extended warranty), Toyota does not expect increased failures in the drivetrain. TRD says gas mileage does not suffer measurably because the blower increases volumentric efficiency. Lextreme guys say it costs 1 mpg around town and none on the highway (maybe Cal can speak to this?)

All in all, despite the fact that $4+ grand could (should) be spent in a zillion other ways, a TRD blower package would be an amazing addition to our steeds. Imagine 25 to 50% more torque an the same prop. Neck-poppin g-force and an amazing look and sound.

Without a 'measurable' increase in fuel burn.

i will do the hard yards an fitt an m90 to my skiboat 1uzfe and put it on the engine dyno to see how much hp and touqe it will have with stock injectors and fuel pump a 1uz freak told me that the stock ecu and fuel systems is good for 400hp and max 5 psi of boost he dyno one in a sc400. if i can supercharge it for around 1500$ aus then it should be cheaper in the usa

Speaking to fuel consumption with the TRD blower:  It's true...no negative effect on fuel consumption whatsoever, at least on my 3.4L.  My brother has a stock 4runner, and we've decided mine actually gets 1-2 miles BETTER gas mileage. But mine runs 0-60 in just over 7 seconds (yes, faster than my old pocket rocket GTI), and my brother's takes well over 11-12 seconds (we've never timed it...no point).

BTW, I just finished the install of my AirLift 1000 air suspension bags and onboard air compressor. COOLEST FRIGGIN TOY ON MY TRUCK YET... The point is to level the car and beef up the springs when towing.  Without a trailer, it will jack up the rear end of my car about 2-3".  I haven't towed with it yet, but oh, it is soooo cool to play with... and I have a feeling it will be highly recommended once I do get around to towing. With the onboard compressor, it is 100% maintenance free (without the compressor, you have to check on occasion to make sure you are running more than the minimum 5psi)... but the compressor regulates it automatically.

400HP would be nice, but 400 ft/lbs would be better ;-)

Cal, the MPG thing still blows me away. And do you use a K&N or other cold-air intake with that blower? 7-second 0-60mph is friggin amazing.

CAN YOU IMAGINE A BLOWN EPIC??

[phenom_1819]

I have the TRD air filter kit.  So still use the stock airbox, but with the TRD filter... 100% identical to the K&N.   Also have the TRD cat-back exhaust... for what TRD says gives my truck 280 hp, which I think is over-rated.  Probably more like 240-250 or so.

And for the record, my 0-60 isn't 7 seconds flat, but just over (like 7.3-7.5 seconds...tough to tell with our very unscientific method).  We did it over and over and seemed to hold true.  I envision the day when an X5 4.0 wants to race, and I take him by a nose off the line...grinning ear to ear...

...then my ear-to-ear grin becomes a sh$% eating one when a Porsche Cayenne S blows by us without even trying, making both of us look like a couple of SUV-racin' jackasses.

Oh well.

So still use the stock airbox, but with the TRD filter... 100% identical to the K&N.  

Well, maybe 95%. The K&N cone filter makes the engine sound 912% healthier, which must be good for an extra five %. When my wife drives (and I'm riding shotgun with windows down), I get the full ear-full. Sounds awesome when you reach speed and ease off on the gas - this bitchen whistling sound like NOS or a huge Holley with the air cleaner removed.

The reason I asked was that TRD 'doesn't recommend' andy 'cold-air intake' systems with their blower. All I know is with 23K on the filter, it's time to get a cleaning kit for it.

[phenom_1819]

Derek- I think we might be talking about two different things. Mine is just the drop-in flat air filter, which I believe was actually made by K&N, with a TRD logo instead.  It slips into my stock airbox.  I think what you're talking about is the cone filter and HUGE airflow tube -- which replaces the airbox in its entirety, and increases horsepower.  

Below is the filter I have (on the left side, second one down).  The one I have doesn't qualify as a cold air intake...it's just a filter.

And about s/c'ing our boats, I don't think it'd be possible with a d-drive, not enough room in the engine compartment.  So I think you v-kids are alone on this one...dammit!

[toyotafreak]

You're right about the intake, and make an interesting point about the TRD filter element. One of the mufflers in the TRD catback is stamped MagnaFlow. Guess the TRD guys have the opportunity to use off-the-shelf components if they fit, and fabricrate new if that's required. Free to mix and match. If I had more skills, my butt would be working down in Irvine at the TRD 'factory'. What a job that could be ;-)

Cal, I'm also interested in how much taller the roots/Eaton/TRD blower makes the engine. My impression from pictures was that the 4.7L doesn't get much taller. I'll post if THE answer's found.

The filter that you have in your stock box is supposed to provide most of the benefits of the FIPK pictured below. Anyways, the TRD blower instructions say that what I got can't be used (will make things too lean).

[phenom_1819]

Funny you mention that -- the guy I bought my boat from actually worked for TRD down in So.Cal.  He was a product development manager, and his first project after joining TRD was helping design the supercharger for the 3rd generation 4runners.  Man, what a job...

When I head that was where he worked, there was no way I could pass the boat up. I bought it right there, over the phone... No test drive, I hadn't even looked at it (other than hi-res pics).  In hindsight, I don't think I'd ever do that again...but I knew that me and this boat absolulely had to be together.  

I'll try and take some pics of my supercharger this weekend. It really doesn't take up much room at all.  Sits maybe 2" higher than the top of the engine...and matches perfectly.   It doesn't do all that much for torque and day-to-day driving, but when you drop the pedal, it'll friggin go.

[toyotafreak]

Well Cal, I have a new hope of all hopes....that you keep in touch with the guy at TRD. There will come a time when we'll need his info and contacts. Who better to put us in touch with a real life Toyota tuner?

[phenom_1819]

I will keep in touch with him. He's been a super nice guy. He even sent over some parts he found laying around just a few weeks ago...always fun to get care packages that you never expected!

Anyway, I'm an idiot when it comes to technical stuff...but will definitely keep communication up with him.  He's planning on buying a Toyota engine, marinizing it, and dropping it into another boat...so he could be a great resource.

His plan is to buy a really old MC P/S 190 and drop a Toyota engine in it (he's a waterskier, and that old P/S wake is legendary).   Don't know why he wouldn't just buy an E21. Either way, he'd be very interested in (and a good resource for) helping the cause.

[toyotafreak]

You might suggest to him (I'm kidding here) that a perfect engine might be a 1UZ with the Eaton M90 blower. I noticed yesterday that TRD is marketing the 4.7L blower kit for the Lexus 4.7L applications as well. I had been under the impression that TRD wouldn't provide parts for the Lexus since 'L-Tuned' is the Lexus equivalent to TRD.

That being said....it seems important to me that they're selling Lexus stuff with TRD part numbers. Now, maybe we'll see them work towards blowers and other accessories for the 4.0L. There's a lot of them on the road.

And a tiny number of them on the water....
