Thanks photobucket for ruining the forums and this build thread. I am going to copy/paste a shit ton of pictures so ask questions if you have them.

i have flipped over my current stuff to flickr but not sure if i will get around to converting the entire thread over. May do a cliff notes version and answer questions if there are any. Anyways, just got my infinity 506 stand alone and found a crazy deal on the DMC crimper i need for the pins in the milspec connector i will be ordering shortly. It is consistently 100*+ in my garage which makes it hard to find motivation to work on this thing. I have reinstalled my engine harness and the chassis harness so now just planning things out and getting ready for final wiring. Still need to order some battery cable, wire strippers, and another crimp tool for battery cable lugs and the infinity connector plugs. This weekend i hope to get the hood cut for the exhaust and do a mock up on ECU location to confirm the harness length.

Here is a quick run through to get us caught up from when she came back from the fab shop.

Didn't do much this weekend as i was helping a buddy with his half mile car. Did get a chance to use his chop saw to cut my dump tubes/ exhaust. Now i need to trim the hood a bit more to clock the exhaust to the left and then remake a shroud! Chopped the intake also to run a 7 inch by 6 inch filter as this one seemed disproportionate. intake needs a -10 bung and the IAT sensor bung too.

did some planning for the harness build. Whipped up an excel sheet with the connector face views and lists of all the pinouts. Need to start cross referencing my engine harness and ecu pinouts and group stuff together. Still need to get the ecu mounted but im tying to find some alumalite locally to mount the ecu and fuse box/relays. Also have to save up to order all my sensors which includes fuel pressure, oil pressure, oil temp, ethanol content, IAT, and a 5 bar MAP.

Cleared up the table to layout the harness
https://farm5.staticflickr.com/4368/...58bfaca7_z.jpg

Current plan is to mount the ECU in the stock ecu location and run the harness behind the heater core box
https://farm5.staticflickr.com/4367/...9c686c13_z.jpg

I hope to be able to run it through the current hole shown below. I will likely use a 90* boot on the flange connector. Going to cut that lower HVAC case bracket and firewall stud next time i pull out the dash

So been trying to get another fuel line/fitting order together to finish up my system. Does anyone know of any braided line that is submersible for my pump plumbing? Everything PTFE doesn't state its submersible and i done want something ghetto with rubber line and hose clamps. Toying with the idea of doing hardlines but then i would have to buy the 37* flare tool as well which gets pretty costly.

Got a lot done today despite the heat. Pulled the engine to install a new rear main seal and then to reseal the pan as i did not replace the pickup o ring and it was worrying me. Next weekend it will go back in along with the clutch/flywheel and hopefully that will be the last time.

and all back together

I need to plug a few coolant ports on the block and the second turbo oil feed before the engine can go back in. Also need to press the larger throwout bearing onto the sleeve and then slap the flywheel and clutch on. Once thats in, i need a driveshaft and clutch line/ master cylinder and drivetrain should be all squared away. going to mount the bulkhead connector sometime this week as well.

Spent some time in the garage and got a good amount accomplished lastnight and today.

Heres the throwout bearing adapter with the ACT supplied bearing which was about 1/2" larger than the collins one.
https://farm5.staticflickr.com/4409/...90015a00_z.jpg

I ordered the cast clutch fork and new clips from z1motorsports

Flywheel on and adapter plate torqued to spec

Clutch on and ready for the trans. i should have stopped here lastnight but kept going which led to alot of cursing and frustration
https://farm5.staticflickr.com/4409/...b3a16c74_z.jpg

so this is where it went wrong. i could not get the trans to slide all the way onto the engine and was about 1/2" short. I struggled for about an hour then got it close enough to pull it on with the bolts. I then realized that there was no play in the clutch fork and it was sitting on the case yet i could engage it using a large prybar. I went to bed and realized later that night that the pivot ball is preventing the clutch from disengaging all the way.
https://farm5.staticflickr.com/4355/...401641dc_z.jpg

Here is the longer pivot i got from collins with his instructions.
https://farm5.staticflickr.com/4381/...4df43449_z.jpg

I ended up calling him today (saturday) to confirm that i should use the short one. After explaining my setup and telling him i had the long one installed, his response was simply "why". No complaints as this is the second time i have called him and he led me in the right direction (first one was about clutch master cylinder size which he recommended 5/8"), just was confused why the wrong one was supplied.


Anyways, after swapping the short one back in, the trans slid right on first try.

Threw the engine back in and got everything torqued down to measure the drive shaft length
https://farm5.staticflickr.com/4339/...2d855d54_z.jpg

Called the driveshaftshop in NC and they told me to measure from output shaft to diff flange with the wheels on the ground and send them the measurements for a quote. I measured first with a measuring tape and got 32 3/8"- 32 1/2". Just to confirm i used this paper measuring tape and folded it on each side which yielded me 32 1/2" so thats what i will be giving them.

Getting my fuse box started once they ship me the correct one. have all the wiring for that and ordered two more crimp tools for the metripack stuff. does anyone know what this harness is for? i had it separated with the HVAC stuff but dont remember where it came from.
https://farm5.staticflickr.com/4336/...065d7189_z.jpg

Once i get the cabin side of the harness terminated i will start with adding the wiring for all my new sensors on the engine side. Still have to get the IAT bung welded in at the charge pipe, -10 AN bung for the breather system, and the second o2 sensor welded up. I also will be running an IGN1A ignition setup which i have to order up along with my driveshaft.

Thanks, i am trying lol. Speaking of wiring....

Big wiring update! i have been planning everything out and making sure i have the majority of what i need before starting with this. First needed the shielded cable solder splices to properly ground my shielded cable. I am using the AEM supplied 4 core cables, two circuits for CKP and CMP each, then 2 more for both knock sensors. This leaves me with 2 extra circuits for use in the future. These splices are lined up with the shielded cable so it can be grounded properly.

https://farm5.staticflickr.com/4392/...1e5cb018_z.jpg

With that being the last piece of the puzzle on the ECU side i zip tied that up.
https://farm5.staticflickr.com/4384/...25f3b7a8_z.jpg

Now i have the harness separated into a power/ground/ 12V switched loom, a wideband/ boost control solenoid loom, a CAN/ 2 step switch/ shield ground/tach loom, and an engine input/output loom. Twisted up the power/ground side which will run to my fuse box/battery
https://farm5.staticflickr.com/4420/...a529ee21_z.jpg

Ready for heatshrink and a deutsch connector
https://farm5.staticflickr.com/4424/...20cb0e35_z.jpg

Started the main engine harness with twisting the shielded cables which will be my core here
https://farm5.staticflickr.com/4405/...cf36e94e_z.jpg

Now typically you want to wrap layers of 6 at a time and because i have 26 total circuits after the shielded wires i wrapped 2 with the core.
https://farm5.staticflickr.com/4376/...1413f0fb_z.jpg

https://farm5.staticflickr.com/4392/...a69d3c49_z.jpg

Fourth layer of 6
https://farm5.staticflickr.com/4358/...896f662f_z.jpg

https://farm5.staticflickr.com/4331/...09c2c3ec_z.jpg

So the industry correct way to concentric twist a harness is to cut all your wire to length (+20%) and then start in the middle and work your way out. It should be done one layer clock wise, then one layer counter clock wise and repeat. Since i have my ECU side terminated already this method cannot be used so i had to do two layers clock wise then 2 counter, and so on. I also had an odd number of total circuits due to the core being large with 8 circuits total (from shielded cable). This left me with needing to use filler wires so after this last orange layer i needed to add an additional layer of 4 more circuits (yellow) to fully fill it out. I do not personally think this is a big deal as i now have 6 extra circuits that i can terminate on both ends without cutting open the harness for future expansion.

I did not take many pictures as it got very difficult to keep the end wound tight while taping and wrapping the last layer. I also cheaped out on spending $30 on a 1500 yard roll of lacing cord so i pulled threads out of the rolls of raw carbon fiber i have.

6 filler circuits pinned on the ECU side and wrapped in kapton tape
https://farm5.staticflickr.com/4401/...052a04c4_z.jpg

All done and perfect length now awaiting heatshrink. This is a 40 circuit total with two 4 conductor shielded wire bundles core measuring .55" in total diameter. I am pretty happy with how this came out for it being my first time. I will be running the modified OEM harness on the engine side but now want to badly build a harness from scratch with new toyota connectors over the winter. This should only cost me a few hundred dollars since i am now tooled to do this.
