Oh ok, for some reason I thought you meant dually tires. Dual cases makes more sense

live4soccer7

Yes, a smidge more.

What adapter and slave cylinder did you use for your R151F?

First of all.... the mileage that Toyota posts for the government website is under what it can get. I have seen many people get more then 17mpg on their V8 models in the thread that was posted and I am running a V6 that gets better mileage.

I dont know how people drive down south but I am getting my stats from actual real life experiences. I am running synthetic lucas oil in my rear diff and regular oil in the other locations. I have brand new Denso O2 sensors and I fill up at the same gas station making sure to get clean gas without any additives. My fill ups match what the computer says. I have seen lower numbers but the picture below is a 1200 km/750 mile trip. The only time i See numbers above 10L/100km is when I start/stop in town to and from my school. I dont even get to warm up the truck before it shuts down again. After 2 weeks of this and the ocasional trip across a 35mph city in stop and go traffic I average of 13L/100km which equals your 18mpg US. That is the absolutely worst mileage I get on the worst possible day.



My tires are goodyear duratracs, they sit at 50 psi all the time, I got the correct denso spark plugs from toyota and I dont punch the gas to get up to speed but I dont drive like a granny. I coast to stops instead of staying on the throttle till the last moment and adjust and hold my speeds before hills (and we have lots being British Columbia).

Maybe this will help others but I think the 5 speed auto with a slightly lower gear ratio behind the v6 would be the best bet. I will know more this summer since I am switching the transmission and transfer-case for a lower mileage 5 speed version. From what I can see its a plug and play.... and a couple bolts for fun :p

Ps. I am not being abrasive or defensive in this post. Just stating facts and answering questions

Oh... typing it into google I actually found a post that states the engine dimensions pretty good.

http://www.xr-underground.com/forum/...ad.php?t=42114

In that post it states

I have read that a stock 1uzfe measures 680mm (which converted is 26.7inches) but all these measurements are from other people and might be slightly off.

live4soccer7

Are you referring to the height of the 1UZ? Great info. I will dig into the swap a little bit more. Do you know of any members/threads that have done the swap?

2big4arunner

those measurements are for the 1gr-fe.

If you want to see who has done the 1uz-fe there is another site called Lextreme that pretty much covers every possible version of using that motor for swaps. Just think it and its probably been done.

live4soccer7

Yes, I have been over to lextreme, very helpful. I've read most of their posted information. I was referring to the measurement you had at the end of the post. I was more curious than anything, no big deal though.

2big4arunner

Yeah, the part at the end under the 1gr-fe measurements is the 1uz-fe measurements.

If no one does it before me I will be doing it myself for a friend of mine.

live4soccer7

Best of luck, hope to see the swap around the forums when it happens.

22R4EVR

shoot I cant wait to swap to the 1uz when the time comes. I love my 22r but im sure I will love a 1uz just as much if not more and im sure it will get about the same if not better mpg since it does not have to spend so much time in a high rpm band as a smaller engine trying to make more power to make it over mountains and what not.

live4soccer7

ha ha ha... I'm with you on that 22r4evr. Pretty much have to have the thing pinned to make it up hills.

I was reading a thread over at lextreme or v8forums that a guy put in the 1UZ, but if he had to do it again would go with the LS1. He said this because if he put 100kg (220 lbs) of his gear in the back he could feel the difference in the truck. I've always wanted to put an LS1 into something, perhaps now would be the time. I'm not quite sure on the lift requirements though. I've seen a pretty high BL in a couple swaps, would be curious if anyone else has good info on this swap.

It is nice to see a modest discussion over this thread instead of a bunch of flaming/bashing.

22R4EVR

right on live4soccer7, then you know exactly what the feeling is like having that heavy foot smashing through the floor. I have thought about the LS1 swap but seems like it would run a little more on the $$ide compared to the 1uz. check out this discussion its pretty good https://www.yotatech.com/forums/f163...88/index8.html

2big4arunner

Stating that the truck felt different once he put the 100kg in is exactly why I suggest the 1gr-fe out of the 4runner. I had to tow a trailer with a 1995 camaro that weighed 6000+pounds behind it to have to use the top half of the throttle. Even then I wasn't pinned while towing that load up a 5% grade. This motor is designed for the truck and suv and its hard to beat a company that produces such great vehicles.

OR.... there is another option if its just for a v8, after 2005 they make the 2uz-fe vvt-i. That motor has more torque then the 1gr-fe AND the 1uz-fe.

And of course there is the hard and expensive route of making your truck a diesel.... not suggested unless you have 10+ thousand to throw at it.

live4soccer7

Yes, I think those engines would be great, but the added complications of the OBII making the ECU's picky as hell will be a big PIA. Just what I've read from 1UZ swaps due to the engine overlapping when they introduced OBDII.

22r4evr: I actually read through that entire thread this morning. ha ha. I'm not quite sure that he actually put the LS1 in it though, despite the title of the thread. I currently have 1" BL and 4" front TG and 5" rear TG on my 4runner. I think more BL may be necessary, however I am not looking to raise the truck anymore. I actually would be happy if it would settle more. My frame height at the door is about 29.5" with 37's. I've spacers and 14.5 wide tires with a decent offset, so it still has a good/decent stance.

I'm pretty sure he ended up with the 5.3L Vortec LM7 engine.

2big4arunner

If you dont want the complications why dont you settle on a turbo diesel unit (pre-obd2)

I have done a few swaps and the sensors related to the engine are pretty easy. Hooking up the speedo and all to the older guages would be an issue on its own. Everything else should be on the wiring harness.

Hey... how about a 7mgte straight 6 from a supra. I got one sitting in the shop just finishing a rebuild.

live4soccer7

I've considered diesel, but didn't see many worth throwing in that aren't extremely heavy. The good thing about the LS1 and 1UZ are they are 350-450lbs. I believe the 22r is about 350ish.

I have considered the 7mgte, however I think I would choose the 1UZ first. That choice has nothing to do with power. I read up quite a bit on the 7mgte as well. Tough choices.

Heres one

live4soccer7

looks like a massive PIA. ha ha. I'm going to look up some dimensions on the LS1 and 1UZ for comparisons.

Wonder if chromoly front and rear axles with the 6spd manual (T56 I believe) and a full floater axle in the back with a fully built dual case with adapter (if possible) would hold up to the LS1 (v6 thirds). Any opinions? It doesn't get driven to hell and back all the time, but it does get used well from time to time.

live4soccer7

Here are some dimensions for the LS1: http://paceperformance.com/p-3990-en...imensions.html
from oil pan to top is roughly 28.25"
from front to back roughly 28.75"
from side to side roughly 24.75"
Weight (rough): ~400 (not 100% certain on this weight)


Here are dimensions for the 1GR-FE (stated above by: 2big4arunner)
from oil pan to top is roughly 28"
from front to back roughly 20"
from side to side roughly 26"
engine and trans total is roughly 53"
Weight (rough):

1UZ-FE (if anyone finds different dimensions, let me know) - http://www.v-eight.com/tech_forum/vi....php?f=5&t=532
from oil pan to top is roughly 25.6"
from front to back roughly 25.8"
from side to side roughly 24.4"
Weight (rough): ~380-400 lbs

22r Series Dimensions (can't find them, surprisingly. Anyone know them?) - For comparison reasons
from oil pan to top is roughly
from front to back roughly
from side to side roughly
Weight (rough): ~350 lbs

5vz-fe Dimension (anyone know them?)
from oil pan to top is roughly
from front to back roughly
from side to side roughly
Weight (rough)

7mgte
from oil pan to top is roughly
from front to back roughly
from side to side roughly
Weight (rough): ~450 lbs

2jzgte
from oil pan to top is roughly
from front to back roughly
from side to side roughly

Can anyone help fill in the blanks?

live4soccer7

It appears that stuffing an LS1 and the 1GR into the engine bay would both be somewhat comparable as far as raw size goes (additional complications not considered).
