Thanks man, it's painfully close to being on the road. Certifier had a couple of points to fix, but all really minor stuff. Was hoping to fly up and drive it home over the weekend but the certifier can't see it until Tuesday. I'm so frothing to use it!

I did look into it, but found aftermarket ECU's around $1,800nz, plus all the wiring, plus tuning. I didn't look into it too much further than that so maybe some cheaper options are out there. Definitely didn't spend that kind of money getting the stock ECU wired up and running. Thank God.

Ha, yeah a small fortune sounds about right. Had to be done though.

Yep, kept the chassis mounts and Fabricated some new engine ones to fit the bolt patterns on the 2J block. I'd bolt down the chassis mounts before measuring up the engine ones. We had to weld on an extra bottom plate to the engine mounts for clearance that disappeared once everything was tightened up. But, we're idiots so... There's enough room for a custom job. At least for the set up we used. If you got your 2j from a Supra maybe it has a better manifold angle? But we had to cut ours up to under the firewall. Chassis clearance was sweet. Yes, we reused the crown radiator. After some discussion with the resident pros, the original was up to the task. I put 16' fan on there too. Keep in mind, everything I've done is still experimental. I've tried to get as much info as possible before making a decision. But the car has only been on the road a handful of times. It did just do a two and a half hour drive from Whitianga to Tauranga not a problem. And if that means nothing to you, it's the equivalent of driving on mountain roads for two and a half hours, without the high altitudes. Very up and down, winding roads.

Wow, epic update. Sorry it took so long.
-
This is where I run out of photos of all the rest of the stuff that went on. Like the full reconditioning of the brakes including a new Booster/master cylinder from an MA70 Supra. The reconditioning of the radiator, and the inclusion of a 16' fan. A new 10 bar oil cooler for the tranny. Plus other things I can't think of right now. But the front end is back on, and I've got some snaps of that and the engine bay. Enjoy. image by toyota2jzcrownbuild, on Flickr image_13 by toyota2jzcrownbuild, on Flickr image_41 by toyota2jzcrownbuild, on Flickr image_36 by toyota2jzcrownbuild, on Flickr image_40 by toyota2jzcrownbuild, on Flickr image_37 by toyota2jzcrownbuild, on Flickr I've also repositioned the filler bottles to the other side of the bay to fit in the intake. image_28 by toyota2jzcrownbuild, on Flickr

Back it up. Before all of this, we decided to remove the air con compressor and power steering pump from the engine. I'll look into these in the future, but they weren't important in getting car on the road so, off they went. The engine looks much cleaner without them. image_7 by toyota2jzcrownbuild, on Flickr image_4 by toyota2jzcrownbuild, on Flickr image_3 by toyota2jzcrownbuild, on Flickr

That was a moment of much relief. Relief that I didn't get scammed with a mismatching ECU, transponder, key. Relief that I didn't have to go back to the net and continue looking. Relief that everything that went into hooking up this engine to this car was working. Relief that the engine itself wasn't a lemon. And relief that I had some good whiskey to toast to that first 'fire up' and that there was plenty of it!
-
Computer, transponder, key combo found! Oh hell yes! Cost me $400 delivered for the lot. Which could've only have been better if it was free (or you know, any number between 0 and 400 ). It goes in and the car fires up straight away.
-
Now before I go on. I'd like to point out that we called the auto electrician out of the blue. An isolated, small New Zealand town business. Not an authorised Toyota dealership. So, hunting down these model specific items are understandably difficult. And I called the big city businesses too, who also scratched their heads, or just told me to 'piss off'. So, if it sounds like I'm ragging on this guy, that couldn't be further than the truth. What these guys do specialise in is marine and off road vehicle electrical solutions. With their hands in some local racing set ups as well. And handing this guy a "fucking mess", and a .pdf file he performed some serious auto electrical wizardry. If you want to know more about him, send me a PM and I'll happily pass on his details. I haven't told him I'm doing this build thread, and haven't asked if he minds I use his name. So.

Electrics. Oh the fucking electrics! (This is where shit gets real) This was something I was happy to put in the hands of a professional. I spent a lot of time beforehand trying to find a complete wiring diagram for the ECU. For a while it proved a futile effort. I've said before I'm new to all of this. There was always a possibility I'd hit a brick wall on this build, and the electrics was almost that brick wall. After exhausting all my Google skills and looking for a wiring diagram for an '01 Toyota Altezza Gita with no luck. It came to my attention that this car was also imported to the USA as a Lexus IS300 Sports Cross. And after much searching I found a complete diagram in PDF format and sent it through to the auto electrician. Who himself had no luck tracking one down. That got the ball rolling, and things ticked along nicely until..... image_24 by toyota2jzcrownbuild, on Flickr image_34 by toyota2jzcrownbuild, on Flickr image_23 by toyota2jzcrownbuild, on Flickr ...who here knows that the immobiliser in an '01 Gita is built into the computer itself instead of the transponder located near the ignition barrel? Not fucking me, that's for sure! This means that if you don't have the transponder key for that specific computer, then that computer is completely fucking useless. Later models fixed this problem, so that if you lost your keys, you didn't need to replace the cars ECU, which is pretty fucking expensive. Toyota told me anywhere between 1 to 4k for a new set, depending on the model. Jesus! Again, the auto electrician couldn't source anything second hand. So the only thing (other than money) that I had to contribute of significance to this build was digging through the bowels of the internet trying to hunt down a second hand, '01 Toyota Altezza Gita ECU, ignition barrel, transponder receiver, transponder key combo. From the same car, so that they would all work together.

Since the donor car had an in tank fuel return, and we were running a different set up a bypass valve was needed. image_42 by toyota2jzcrownbuild, on Flickr
-
The fuel pump is a Walbro 255 in line. We added another filter before the pump to try and catch any shit that'll come out of the old tank before it can do any damage. Needless to say it was flushed and emptied first. Can't be too careful right? image_21 by toyota2jzcrownbuild, on Flickr

The exhaust again isn't pretty but it's effective. image_22 by toyota2jzcrownbuild, on Flickr image_17 by toyota2jzcrownbuild, on Flickr image_19 by toyota2jzcrownbuild, on Flickr You can also see the driveshaft has been done. We sourced one from a Altezza Gita (IS300 Sportscross) and had it cut and balanced.
-
Next, extractors and exhaust. Since the factory exhaust manifold didn't fit it had to be cut. I can't say it's the prettiest job in the world, but it'll get the car on the road and I can get something sweeter fabricated in the future. With a turbo manifold perhaps?! image_6 by toyota2jzcrownbuild, on Flickr image_5 by toyota2jzcrownbuild, on Flickr

Installation and calibration was pretty straight forward. image_11 by toyota2jzcrownbuild, on Flickr
-
After some internet research I found a device called 'CableX' from Abbott which handles this function. All I had to do was show them a pic of the speedo connector cable and they wired an adaptor onto one of their devices. 20140112_144908 by toyota2jzcrownbuild, on Flickr 20140112_143850 by toyota2jzcrownbuild, on Flickr

I wanted to keep the original dash in tact, as it was in such good condition. That meant sorting out the problem of running the analogue speedometer and trip meter in miles an hour, from an automatic trans computer reading kilometres an hour. image_12 by toyota2jzcrownbuild, on Flickr

Hi guys, it's been a while, but this project has been moving along all the while. As of now it's waiting for certification in Tauranga. So much has been done, but I don't have photos for all of it. Let me try and remember all of what's been done in this time and I'll put up some photos where I have them.
-
.....And just like that I've found what I'm looking for. All sorted, Cheers guys.

Hey all, I'm trying to find a complete wiring diagram for my build, and it seems pulling complete ones from the net is proving difficult. I can get input diagrams for the back of the computer, but nothing on wiring layouts. Can anyone recommend a good source for finding these? I'm specifically looking for one for an 2001 Toyota Altezza Gita (or Lexus IS300 Sportcross), but a point in the right direction would be awesome! I'll carry on trawling forums in the meantime. Cheers Inerweb gurus and analogue warriors alike!

Hey automotive ninjas, I have a few questions I need answers to. I'm gonna look them up on the interwebs, but I thought I'd throw them out to you guys as well. You may have some quick answers for me that'll save me some googling time. Does the 2jz-ge vvti have a fuel bar overflow return system? The 3"8 outlet pipe at the back of the block under the manifold. Is it for a heater pipe or engine cooling? Will the power steering sensor in the engine computer cause problems, if we loop the outlet to the return on the power steering pump? Or there a better way to do it? Is it easier to just take the power steering pump off the engine and run a shorter belt? I hope those make sense. Any help would be much apprech! Cheers guys.
-
True that. Any engine work is way down the track! The focus (like you said) is to get it on the road. And big billowing smoke out the back with a straight pipe is all I need.
-
Cheers dude, We can chat about improving the "epic handling" in the future. Far, far into the future!

For the engine mounts we cut a chock and used it for the template. IMG_2320 by toyota2jzcrownbuild, on Flickr IMG_2321 by toyota2jzcrownbuild, on Flickr IMG_2325 by toyota2jzcrownbuild, on Flickr Then cut some steal and grinded along the creases to thin the steal enough to bend it in the vice. IMG_2333 by toyota2jzcrownbuild, on Flickr Welded the creases to re-enforce them, IMG_2335 by toyota2jzcrownbuild, on Flickr and bolted in. IMG_2349 by toyota2jzcrownbuild, on Flickr It's not pretty but it fits sweet, and not bad for a first effort. So the engine/trans is now bolted in, and I'm stoked with the progress. IMG_2365 by toyota2jzcrownbuild, on Flickr IMG_2368 by toyota2jzcrownbuild, on Flickr And when the bonnet (hood) went on, I got confirmation that the engine was the right choice. Super stoked!
