1UZFE - Considering ITBs and Cams. Thoughts?
I'm toying around with the idea of some individual throttle bodies and slightly bigger cams on my 1UZ SC400 (non vvti).
I'm wondering if I'll need to purchase a different piggyback system (currently have SAFC) to make this system work together and gain slightly more power. My hope is to get near 300 to the wheels in the 1UZ with this setup and tune.. nothing crazy
Would I need to scrap the SAFC all together and get another piggy back or perhaps a stand alone system such as ProEFI or AEM? Right now she has manual tranny (w58), rush headers, intake, and custom single exhaust (2-1) no cats or resonators. The purpose of the vehicle isn't for drag racing or anything, right now I'm having a bunch of fun throwing it sideways with the 1UZ. Replacing the motor with a 1J or 2J isn't an option, and I like the idea that if this 1UZ gets destroyed, I can simply buy another for under $800 bucks.
So, any tips or recommendations on upgrading my current setup with ITBs and Cams or one over the other would be appreciated
Here is a Supra that did something similar.

Well, in short yes, you'll need a stand alone plus, ITB's at the cheapest are like $900 so with the stand alone and ITB you are already around 2k, before cams and installation.. :/ At least if something happens to the motor you can get a junkyard swap for like $250 all day.

it only makes it sound cool, there are lots of videos online of it. ITB changes the engine alot, you will need a more capable piggyback like the aem fic or a full standalone to take advantage of the ITB's, even then its tricky.
I would look into boosting the 1uz, the cams are already decent for hp applications.
the first thing I would do is look into a centrifugal supercharger on a fish bracket.
If you have more fab skills, then a real single turbo setup is always a great power adder.

The car is really loud, it almost sounds like an LS when I get on it. A few people that I've drifted and raced say it sounds a lot more powerful than it really is, and they're right.

the fish bracket requires relocation of the battery, and I am not sure about the fusebox but its easy to turn sideways if needed. you do not have to delete the a/c as far as I remember, they usually say that for single turbo setups cause the exhaust comes right where the compressor sits, but for a supercharger there are no mods to the exhaust. believe it or not the fish bracket is 90% of the fabrication already done, just bolt up the right supercharger and oil lines and presto you are good to go.
relocating battery to the trunk is very easy, its about the same difficulty as running a power wire for an amplifier in the trunk if you have ever done that. from the stock positive wire I have one large wire going to the trunk that connects to the battery with a fuse right next to the battery, and a short wire from the battery to the closest chassis ground bolt. I used a $10 plastic battery box and made a couple holes in the bottom and bolted it down, if you have removed the stock amplifier and cd changer, you can pretty much reuse some of those bolts to secure it down. if you still have those you can do it anywhere else in the trunk its not difficult and helps with the weight distribution on the SC.

You can still leave the factory 6 gauge starter wire at the engine and do a terminal block to "splice" them together. The factory wire just has a terminal lug at the battery clamp, anyway, so a simple stud-type block would work well. There's also distribution blocks with studs and screws, so you can put your new battery cables on one side, the factory starter cable on the other, accessories in the screws. Then screw the block and its cover in an easy to reach area out of the way of your new SC/Turbo and pipes. If a turbo make sure it's far enough away from the exhaust side that it doesn't melt.
And wherever you run it through the firewall, make sure it's well protected from shorting out against the body.

I am actually in the process of making a spacer for the 1uz intake manifold for have some more air volume. I was wondering if anyone else has an intake manifold that has been modded or made.

I say go ***** out. Like you said 1UZ is easily replaceable if anything goes wrong then its just taking the bolt-ons off and putting em on the new engine. I was always interested in finding out what a 1UZ can do NA. Standalone for sure especially if you have cams intake exhaust fuel etc

Last question regarding stand alone ECM on 1UZ NA; Would I still go with the almighty AEM/ProEFI stand alone ECM?? Or is there a particular stand alone that is ideal for NA?

Yeah absolutely my thought as well. Break something, and transfer it onto the next 1UZ and drop it right back in.

I was thinking Megasquirt as far as engine management. It's a V8 and it should respond well to more air, more fuel. Guys in Australia have all sorts of great thigns for that engine, not so much stateside. Have you seen the videos of an ITB 1uz?
