Hello folks,
Been reading around these forums for a while now, and finally decided to post. I have a variety of goals for my build, and was hoping to get some direction on a few details I'm fuzzy on.
Quick info about the car: I have an 86.5 MKIII Supra N/A in dark blue metallic, blue interior w/Sport package (LSD/TEMS). Interior is in excellent shape, exterior is pretty decent. Currently on fresh Illumina II's/Eibach Pro Kits. I've owned the car for about 8 years. The 7m and trans are pulled, as the dreaded BHG got me at 132k or so. The idea was originally is to swap a 2jzge vvti, but the engine I purchased proved to be a little shabby and I sold it.
Now, after some reading I want to use a 3uz from an LS430 (which is rear sump I think). I have a 94 LS with lowish miles (130k) as a commuter and love the motor. The early 1uz is stronger, but has less power and I don't want to fuss with boosting it. I want simplicity and stock reliability (And lower cost). 300+hp/TQ from a lighter powerplant sounds good, and really my w58 trans can't handle much more than that. Plus that V8 roar. Cost is a factor for me. I want AC, power steering, etc.
Questions:
After reading various threads, I've seen people insist electric fans were needed, but I've also seen builds posted by Lex that used hydro fans from a JZA70 I believe.
I want to run an OEM rad/fan combo and steer clear of electric fans. My initial thought was to run an OEM LS400 fan clutch/Fan, and a 7m rad, but this probably won't fit. Since those threads are pretty old, has anyone found a better OEM style setup? What do you do for a fan shroud? Are custom hoses mandatory at this point?
I've seen recent threads with George_R where he tunes stock 3uz ecu's, (a little more power at lowish cost is welcome) but I'm a little vague on how I would get one to work with the mkiii. I know he can do fixes for missing trans/immobilizer. I'm just not sure how I would get everything to work. I've seen mention of a celica(corolla?) tach sender? What about idle up for A/C? TEMS? I've read there are a couple outputs on the stock ecu that tems uses. Seeing as I went through the trouble to find Illumina II's (which I really like) keeping the functionality would be nice. Would I need to retain the original ecu for some functions? If I wanted to use an early 1uz cable pull throttle, can the 3uz ecu run it, or would I need a Link ecu? I saw a build by yotarip where he used a 1uz vvti ecu/cable on a 3uz, but I don't know if those are tuneable. What about cruise control? The system uses a servo to pull a cable I believe, so it will probably work with the old uz setup right?
Headers/Exhaust: I've seen gloverman post that he prefers 2.5", but what headers should I get? I'm hoping for better than stock hp, and a little noise but not a ton. Maybe single exit, high flow cats, vibrant straight through resonator, borla muffler. EGR delete. Just spitballing. Any intake suggestions?
I plan on using the XAT adapter kit with hydro clutch, and hopefully I can score a motor with the tranny on it so can take the bell. Their lightened chromo flywheel sounds appealing as well. I am, however, unsure what clutch to use. I am hoping to make 350 flywheel if all goes well, so I don't need a hardcore unit, and I don't want to blow up my tranny if it grabs too hard...
On the AC front, I still have the original 7M system hooked up/pressurized, and it works. I was hoping it would be possible to create a bracket that would mount the compressor to the uz. Does everything spin the same direction/should it fit?
If anyone has any thoughts on the above, I'd really appreciate it, thanks.

. Thanks for the quick response, and for the videos!
. Though it is something to consider. Are any sensors required to be installed for such a function? Do you have any knowledge of TEMS? I've seen threads where people claimed it worked fine after a swap, and others not so much. I know it has its own computer, but the TSRM says ECU pins 3-7 are related to TEMs, but how or why is not specified. It also uses the TPS, and I'm not really sure how that transfers over to a UZ either. If all else fails, I'll probably just rig up a way to switch it full on from the cabin, but that would be a shame. Does using a 3uz ecu require an electronic pedal/throttlebody? What about cruise control?
