Dream Project Might Be Coming True!!!

So back in December I decided to do a motor swap in my 4runner and I had no idea what I was doing. I bought a 4.0L V6 (1GR-FE) for my runner then later decided to sell it and just beef up my 3.4L (5VZ-FE). Well I ended up dumping a ton of money, as a matter of fact more than half of what my 4runners worth, into my engine and even though what has been done was all built around a supercharger, which is already paid for and ordered, Im not to happy with it. Even though I shouldnt jump to any conclusions yet since the supercharger hasnt even come yet, I still feel like this is turning out to be more work than its worth.

Well, ever since I had the idea of doing a motor swap, Ive been researching other Toyota motors just for fun and recently I stumbled across a motor called the 1UZ-FE which is a 4.0L V8 used in the Lexus SC, LS and GS series. It is probably one of the best motors Toyota has ever built and not only is it cheap but they're pretty easy to find. As a matter of fact, swapping out the 3.4L in the 3rd gens with the 1UZ is actually a pretty common swap.

For those of you who don't know I recently sold my Camry and bought an Audi A6 cause I got an insanly killer deal on it and I dont really like it very much so I've been thinking of selling it.
Yesterday I came across a 98 Lexus SC400 (which has the 1UZ) for $1800 cause it was a project car and the guy tore it apart then decided to sell it. So Im going to go take a look at it on Monday and I might be bringing it home with me.

I haven't really kept anyone updated on the progress on my 4runner cause it always seems to start an argument, but I figured this might be something worth letting everyone know about.

I'm pretty serious about this build, actually to be honest I'm about 90% sure Im gonna actually go through with this. Oh and p.s. I am gonna keep my V6 and I think Im gonna throw it in the Lexus and keep building it once my 4runner is done.

Now I know a lot of you are gonna tell me that I should just build the Lexus but because Im stubborn and hard headed, Im still sticking true to my plan to have a 13 second 4runner that can still be taken offroad.

So as for all the recent modifications I haven't really done much. I've been doing a lot of planning and preparation for up-coming mods. So here's a list of what I've got coming up and what I've already started on.
New, blue LED's for the interior, I am doing a manual swap and I already have the transmission but I'm waiting to sell my auto to buy the rest of the stuff for the manual (clutch, clutch pedal, flywheel, master cylinder, ect) I am doing something really cool with the exhaust but I'm running into snags left and right. Im cutting holes in my rear bumper and running dual exhaust into them, kinda like the Corvettes. and yes im using my Jardine exhaust so no you cant have it :p Im looking into reupholstering my interior, getting black leather for my seats and making parts of the dash and door panel trim black too. I just ordered hella fog lights a few days ago so those should be ariving soon. I just got clear corners and blinkers and chome blinker bulbs from Mr. Burtman (the man, the myth, the 4runner god :p) I am custom fabricating brake cooling intakes on the sides of my lower valance just in front of the fender flares, which was turning out pretty well until I melted the plastic on one side so I just had to order a new lower valance :bash: and last but not least, Im still looking into a coil and shock system that will allow me to raise my runner 3" above stock and and lower 2"below stock at the push of a button. I do have a lot of leads but Im just having a hard time trying to decide on which system I want.

So there you have it. Ill post pictures in this thread when I finish each project so keep checking back :biggrin2:

Thanks,
Matthew Starr

Another plan. I hope this one goes through. :D

How much HP and torque are you expecting out of this new motor?

What were you expecting out of your bored and supercharged 3.4L?
 
1UZ is a nice engine to start w/. I looked at doing the swap into my IS, but because of the year i would have had to do the 3UZ which while it is a bit more advanced, the price is a lot more than the 1UZ. Good luck w/ the project.
 
Very interesting. Certainly a challenge but it sounds like you're up to it. Hope everything goes well. Keep us posted. :bigok:

Well as it sits, my 3.4L dynoed at 192 rwhp a few weeks ago. The problem is that since I replaced the cams my redline is now at about 7000 rpm but since I have a stock tranny, it still shifts at 5500 rpm, so for all I know I could be getting 240 rwhp at 6200 rpm but I wont until I get my manual installed. Im guessing I might be at or close to 300 hp with the supercharger.
The 1UZ on the other hand sits at 215 rwhp in the Lexus and thats bone stock. Not to mention the 1UZ has a 6 bolt main and cast steel internals so I can throw gobs of boost into it and not worry about a thing. Theres a guy with a turboed Lexus SC thats pushing almost 300 rwhp with only 8 psi. Not to mention, aftermarket support is abundant.

Ya, I think I'm gonna take some classes at Lincoln Tech (automotive college) while I'm doing this cause I want to do it myself but Im still pretty in the dark about a lot stuff. So if anything this will be an awesome learning experience.
 
Im pretty sure this swap has been done on the 2nd gen 4runner. I'd like to see it done on 3rd gen good luck with this it.
 
Some of you have already seen this one-2nd gen with a 1UZFE V8 not sure if thats the 4.0 matts talkin about, correct me if im wrong. But i love the sound of that thing!<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/A3oV48rV4ug&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/A3oV48rV4ug&hl=en&fs=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>

PS: Good luck with the swap, I'll definitely be checkin back on this one!:D

Cheap projects usually end up being expen$ive projects, or stillborn projects. Have fun.

X2. That seems to be how all my projects go. Good luck and let us know how it goes.

Yes that is the 1uz. The 1UZ-FE is a 4.0L V8 alloy block with a 6 bolt main and steel internals. The 2UZ-FE is the 4.7L thats in the Tundra and 4th gen 4runners. The 2UZ is and iron block with aluminum internals and only a 4 bolt main. Then theres the 3UZ-FE which is a 4.3L aluminum block V8
From all I've read the 1uz is the best motor for building.
Oh and heres a 3rd gen with the 1uz :biggrin2: http://www.uzswap.com/forum/index.php?topic=150.0
 
A friend of mine had two V6 4runners with rebuilt motors. A third and a second gen. BOTH blew up. I'm sure there's exceptions but from what I understand these motors don't like to be opened up.
