In looking at the JBA, that might be the best bet aside from fabbing my own.

JBA's shorty header:

But I've got concerns that the big triangular flange they use won't clear the frame rails.

The other notable are Flowtech headers:

While these are a good efficient equal length design, the tube routing makes them pretty large - I doubt they'll fit the space available also.

The JBA looks pretty good - I just need to make sure it doesn't stick out from the head too far.  I can always change the collector flange if it gets into the frame rail.

[cebby [OP]]

These things came out further than I thought, the tale of the tape...


Almost 5 1/2" straight out from the heads.  I need something that turns down instead of straight out.




Other side...


It appears the JBA headers won't work either due to where their shorty layout puts the collector flange (in my case this would be into the firewall.  Big thank you to "Brad Bedell" on Lextreme for the pic. (He swapped a 1UZ into a Lexus IS300 Sportcross)

[cebby [OP]]

Forgot to mention - 1UZ, 2UZ and 3UZ exhaust port layouts are the same...

[BUDDERS]

I know that each body style that the "UZ" series engine is in takes different exhaust manifolds.  If I remember correctly (from research done a year ago) the a lot of guys on the Lextreme forum are using LS400 manifolds.  If I remember right, I think they hug the block a bit closer.  I'm not too sure if they point down or not though.  Dang, I kinda wish I was working back at Lexus again to help you out with some exact knowledge.  Oh well, the Toyota dealership still beats the hell with an "L".   

[cebby [OP]]

I'd love to find a cheaper "stock" alternative.  I wonder what the stock 2UZ manifolds look like...

Check out the fit on Mudman's headers (see pics up above - with blue background)

He did some nice work on fitting those in amongst all of the IFS and tight 2nd Gen engine bay (pics by Mudman from Lextreme):










Mine will be slightly different, since my motor will sit a bit lower in the frame than Mudman's...

[BUDDERS]

Wow!  How in the world did he wiggle those in there    It looks to me that you would have to pull the cab off, and set the engine and trans in place, then drop the cab back on.  It looks super clean though.  Good luck on that one. 

[BUDDERS]

I think the easiest way to mock those up would be to pull the cab off too.

[cebby [OP]]

Finally got a chance for a 2nd Fitting yesterday.  Thought I'd post up some long overdue pics...

These first two are for SuperRunner (shows the speed sensors on the A341E and A340F)


The additional speed sensor the 1UZ ECU needs to see can be added easily to the A340F (since you need the input/planetary from an A341E which has the sensor tone ring on it already, it should be plug and play)


I pulled the exhaust manifolds off so I could get a better fitting this time around.  This was a big improvement...  A few shots for reference:

Passenger Side:


Is it just me, or does thing look like it's ALL MOTOR? 


Driver Side:


Business End:


After numerous adjustments, I think this last shot is pretty close to where it will sit.  I will have to modify the steel oilpan (may make from scratch - probably easier) - jury is out on the pickup tube for now though.  I need to pull the aluminum ring off to mount up the pickup tube and then go for a 3rd fitting.  This is close to the final position - shifted it over a little to the right and there was good spacing all the way around.


Here's a guess at the oilpan mods.  Might be more, might be less...


Clears the breather extension and ARB line perfectly.  Although, I will likely raise it up some for breathing room.


Now that I got it tucked down nicely, the motor mounts will actually be pretty short now.  I measured and it appears they will be roughly 2 1/2" to 3" off the stock 3VZ rubber mounts.






I am hoping to remove my 1" BL, but I'm still not sure that can happen yet.  Going for low and planning to hack my fenders/footwells.

(like my shim?)

Did another trial fit of the oil filter mount.  Framerail clearance is an issue.


On the left is the 1UZ filter on the right, the 3VZE.  Neither of them make it. 


Looks like a relocation or more of a block hugger mount is in order.

Not sure yet, but it appears that the stock steering stabilizer location can be reused.  Might be tight with the beefy OME though.

Hey - anybody know what will take the paint off that the junk yards use to tag their wares?  Not wild about this being on the final product.

[cebby [OP]]

Not exactly tech, but some progress.  Pulled the motor apart again...load going for powdercoating...  I had all the big stuff hot-tanked.

The cam covers and intake will be dark dark blue and the fuel rails and related stuff and nuts/bolts will be gloss black.  The fins on top of the upper intake will be either silver PC or raw and polished/brushed.  I plan to paint the plastic plug cover ridges to match (silver).

[BUDDERS]

I'm waiting to see what it looks like when it gets installed.  Should be pretty

[Marc P]

Brake parts cleaner takes that paint right off.

Looks really good.

[cebby [OP]]

OK, we're working through the Lexus control of the Toy trans currently.  Anyone familiar with the Lexus control of the TCC solenoid?  It appears to be PMW (pulse width modulated) control that is different than the Toy version.  This Lexus TCC solenoid has 2 wires and the Toy one as 1 wire.  Also, the Lexus one is about 2" bigger than the Toyota one (comparing a341e Lex trans vs a340h Toy trans).

If anyone can offer some insight, it would be much appreciated...

[BUDDERS]

Cebby, I'll see what I can dig up at work on Monday.

[cebby [OP]]

Did you find anything Budders?

[BUDDERS]

Sorry Cebby, I got caught up replacing my floors last week.  I'll have to write it backwards on my forehead or something so I will remember.

[cebby [OP]]

Sneak peak:



It's a nice dark blue - nearly identical to the body color of my 4Runner - I think this pic is close to the real color.


More to come!

[cebby [OP]]

More goodness:

Lower intake:


Valve Covers:

[cebby [OP]]

More engine PC done (hub dials too):

[Marc P]

Looks good Cebby. Get that bad boy running!!

You need to come out here to Cali and get a non-rusty 2nd or 1st gen to put that in. Find one with a bad motor, and swap all your goodies.


Miss the updates on YT...

I hear you on the rust free vehicle.  This is not my last swap - just my slowest... 

The YT thing couldn't be helped.  I'll still contribute to the tech over there - just won't be nearly as much as before.  Sad really...  I have it on my UZ swap site and about 6 other places, so I think we got it covered.  My UZswap site will contain the most detailed tech for sure.

[cebby [OP]]

What, no one's curious?

Pardon the dust...







These are much darker in person.  A very close match to my 4Runner paint.

[cebby [OP]]

OK finally got a couple of hours to do some clean up and start assembling my 1UZ today.

First I installed the plug tube gaskets into the cam covers. 


Hit them with a coating of oil to make it easy to insert them.




Here's where the inventiveness comes in...  I took this shot on a timer and held the camera under my chin to get the shot (that was my 2nd try)


Here I've taped off the various passages so I can give it a cleaning - obviously not a Smitherz level of cleaning, but I wanted to get the grunge off of it while it's all apart.  This is a pre-cleaning shot (although after the cleaning, it isn't vastly cleaner - at least I know it's clean...


Here's some teasers with a few of the parts on the engine (not done cleaning yet though), plus I need to get bolts for the starter to reverse the mounting for easy removal.








Maybe a new avatar??


Here's the color match.  Since I was trying to match a dark metallic, I opted to match to the bright-sunlight version (as in the color it takes on when it sunlight).  As anyone who has dark metallic paint can testify, it looks different in various lighting conditions.  It's not exact, but it's a stock color I'll always be able to get.
