I'll definitely be trying to find another Mk3 ECU, even though I have a local friend who's keen with a soldering iron and well, well-versed with this vintage of Toyota and their motors. It's just common 1J sense.

Eventually the plan is yes, to go Standalone; as this motor is pre-OBD, there's zero data-logging ability as it stands.

My main problem was that, i assume, with a larger than factory(jdm soarer 1jz) intercooler setup, 3 inch downpipe, etc. it always read rich as hell on my wideband at idle and cruise speed, and slightly lean WOT. That, coupled with boost/speed-cut, i was at a wall with being young and at the end of my budget, with no cash left from doing the swap tuning wise.

Edit: i very well may have had other issues i didnt at the time have the ability to diagnose, poo poo i even drove on 4 cylinders for a few weeks to get to work because a cap in the ecm blew out, until i finally nailed down the issue.

Going back, knowing a fair bit more about engine management(but from looking at megasquirt products, not nearly enough, god drat), i would invest in a megasquirt or something and do tuning yourself, because gently caress paying someone a grand to tune your car, once. My coworker at the Audi dealer i work at, uses software that can tune Motronic ecms, and he will spend a few times a week fine tuning his 2.7 s4 avant, and is even running e85. Do a couple pulled on the way to work, tweak it, test on the way home. Having that kind of freedom to tune it just right just seems like common sense.

Until my kid gets older and I can have money pits again, ill just live that life vicariously through you.

EMS was going to come after the rollcage, which truly is the next step; I love this thing, but don't want to die in it, and part of the reason I haven't done a ton to the interior yet. I'm going to need to do a lot of research; my 'known' options for EMS on the 1JZ are MegaSquirt (because it does everything), various AEM products, and if I somehow win the lottery, a MOTEC setup. EMS and tuning are not within my scope of experience so far, but obviously we're going to change that.

Very much so. I got a hoss of a rivnut tool, though still a relatively inexpensive one, to put the M6 threaded inserts on my Cherokee for the roof rack, but for the smaller sizes (M3, M4) you should be able to get away with the pop-rivet style gun.

I got an Astro 1442, at $70: https://www.amazon.com/Astro-Pneumatic-Tool-1442-Setting/dp/B003TODXQW
It does M5-M8, and 10-24 - 5/16"-18. Other mandrels are available.

If you just want metric, the Astro 1427 is only $40, and does M5-M12: https://www.amazon.com/dp/B004KLVJAA?psc=1
I've got American junk, too, so I paid more to be able to fart with those as needed. No more Tek screws for me!

There are some that use a drill to drive a threaded collet. Not sure how well they work, but they're around $30. and the one-hand rivet-gun style ones are all over the price range, depending on brand, metric/SAE, and what sizes they can do.

Alright, so. Few things sorted out. I tried working on it tonight to overcome Project Inertia, but the 1.5 ton jack's apparently blown, I'll have to get a new one

1) I figured out why I can't connect my e-brake; it's because I was missing the cable stays that allow the cable proper to move in and out of its sleeve. I bought my calipers from ye olde Reiley's unloaded, so there were no pads, slides, brackets, or boots.

This was resolved by junking a pair of the cable stays from an S14 in a yard nearby.

2) New rear brake hoses have been acquired. I totally hosed up the routing on the first go-round, and realized they've been rubbing on the cv and its hardware; corded almost through when I looked at them. :siren:

GOOD THING I DID NOT DRIVE ON THIS :siren:

3) Diff seals great. Finally. gently caress.

Still to do:

- Polish up some ground spots in the engine bay
- Make sure the wiring harness is in the right place
- Bleed brakes
- Run fuel hoses.
- Chase electrical gremlins in body harness, if any, after re-soldering the defroster pigtail.

I would like to sincerely thank Korwen for loaning me his harbor freight jack tonight since mine gave out The thicker, proper late-model ST rear sway bar is on, and PRAISE THE OMNISSIAH clears my driveshaft.

A hiccup with a much cheaper fix than anything else I've hosed with so far: I have to clock these calipers/brackets to the back side of the axle so the brake cables meet, and get my grubby mitts on some clevis pins:

I think the only reason I mounted them this way in the first place was because of these incredibly short hoses, which made this configuration 'look right'; now that I have the parking brake cable stays installed, it's obvious they need to be flipped. I had some nice stainless steel lines braided lines that came with the disc conversion kit, but the private-label manufacturer who did them for the kit-basher was kind enough to send me one of the two with an improper flare type fitting at the wheel side instead of a right and good banjo bolt.

With all the tractors around central Texas, it should be easy enough for me to find a hydraulic shop that can crimp up some hoses; while I'm calling around today to see what costs are like, I'll see if I need to bring my own metric fittings or if they keep a supply on-hand.

I feel this and donuts could fall under the umbrella, yeah.

I may elect to do the loud stuff in a carefully-selected parking lot instead, because the courtesy of my neighbors has thus far been legendary; I had no less than two random dudes come out of their apartments far after sunset, a sheriff and an ironworker, to shoot the poo poo with me and lend a hand just because I was working on it in the lot.

poo poo, I forgot this was a thread! A lot has happened; the fuel system is now manifold, with the A1000 mounted to the firewall. Much has been cleaned and tidied up, and importantly, I am now officially the second legal owner of this chassis ever, with the title blue, clear, and free in my name after 30 years of bureaucratic limbo.

We worked late into the night Monday to screw in the hose clamps for the under-chassis fuel lines along the inside of the transmission tunnel. I now have parallel AN -6 hoses for feed and return on the driver's side of the trans tunnel, well out of the way of the driveshaft and gearbox, and tuned for fluid physics. The tires are now correctly oriented. My accomplices tidied up a few things I forgot, including tightening the end links, and ziptied the wires. I cannot believe how much faster things go when you have two extra capable people helping. Also I love my girlfriend, she's amazing.

The Police apparently thought we were stealing the vehicle from my apartment's parking lot because we were working on it so late, and dispatched a helicopter to tight-circle us at 1 AM. I think after the first pass or two they realized Grand Theft Auto charges weren't going to materialize, but loitered for about 30 minutes until an actual patrol car came by to confirm on the ground, and I like to think they were speculating on it while we were wrenching.

What remains for ignition:
1) Battery box needs bolted in. I'm going to mount it behind the seats on the parcel shelf between the foot lockers, dead center, so I can easily reach a breaker if I need to.
2) Transmission, diff lubes, coolant.
3) I discovered the barb on the MAP sensor has been broken all along, so I can't actually start this vehicle until that gets replaced. The only cure for this ailment is a fresh Toyota P/N 89421-12111, which looks like it'll run me about USD $100. There's a Alibaba Special version of the sensor, which may very well work just fine, but I'm not going to risk a generic at this time.
4) Rack alignment. Car's front wheels are a few degrees duck-footed.

After the car fires up...

5) Insurance! I am liking Esurance, but they don't cover vehicles older than 1981, and instead refer you to Hagerty. I'm going with GEICO until I can get this thing its own garaged spot, even though they can't offer me collision on it.
6) Headlights and turn signals. Not integral to the vehicle's operation, but required to not be an rear end in a top hat.
7) I need to move the fuel pump a little more inboard. It's not perilous per se, but I'd really like it to be more centered, or at least gravel-guarded with an extra piece of shielding.
8) Weatherproofing. The chassis has no rubber bungs to keep the rain out. in the firewall or on the floor. I may get some cheap weather mats to give the car a semblance of interior comfort while I'm finding the nicest ways to route the wires.
9) Hood pins. I had to grind off the stock hood catch for the 1J to fit. I'd like to use Aerocatch products for this.
10) Cage cage cage cage cage cage cage cage cage cage cage cage cage. Frame rail and rust repair as necessary. Really don't wanna die in this thing, but I need it to move under its own power so it doesn't cost me $120 to tow it to anywhere it needs work in the future.

At first I thought they were out just in the area for a fleeing suspect or something, but they never lit up a spotlight, and the circle they flew was tight on us for their loiter period. I feel I missed an opportunity for a posterboard imploring them to, "SEND SNACKS AND RACE GAS"

loving neat, it cranks.

I solved the problem of distributing main battery (+) feed via muthafuckin car audio components and the power of THE CONTAINER STORE:

(extremely professional)

The four red-on-white wires are the Datsun's main chassis power wires. They used to go to fusible links; now I just use mini-ANLs.

These custom audio junction blocks are great; accept 1/0 feed and distribute out to 4x outputs, up to 4-gauge size. I think people use these to drive amplifiers...? Hell, works for me.
The sandwich box works remarkably well for keeping rain off the blocks. Yes, that is totally a piece of scrap wood mounting the distro blocks.

The wiring for the Taurus fan used to run all the way to the back where the battery is; I shortened it now that I have a nice distribution block up front.

That's how much of a run I saved tying it to the (+) block instead.

Spent some time tidying up the headlight harness, too:

Current moods:
- wow it loving cranks
- it's 27 degrees outside
- A Bosch 044 is VERY loud
- _{shall we see what happens when we put gasoline in it? I think we should}

its cold, my hands are cold from crimping, but at least these wires are hot

You'd be surprised how simple it is; you just basically feed everything (+) power, and make sure the other end of the accessory, whatever it is being fed, is grounded.

This diagram sucks, but my battery positive "rail" looks like:

code:

                        ________( - ) [[Batt]] (+)_____(+)| starter terminal
                                                       (+)|___accessory/harness power lead
                                                       (+)|_______alternator positive/charge lead
                                                       (+)|_________junction box power lead_____________________(+) [[junction box]] ( - )__&#9178;

You rail your constant/positive power wires together (starter+, accessory harness+, alternator charge+, and battery+) through your splices, junction boxes, wire nuts, etc. and it'll all charge OK. Make sure the grounds are all there for everything you feed, too, or at least they have paths to earth; current can't flow if unearthed, because dead end.

Yeah, I've been reading up on stuff and looking up power/relay block builds recently. I've got the general gist of things down, I think. Big power to block, power to feed pins on all relays, ground pins all go to common ground, switches feed the trigger pins, output pins feed devices. The whole feeding the block and the starter thing is what's been hanging me up.

I'm sure there's probably specialty automotive stuff for everything I've done so far, but here's what I used:

These (Crutchfield link) distribution blocks have 2x 4-gauge or 1/0 inputs that are daisy chainable. Up 4x, mini-ANL fused, 4-gauge outputs. Stinger has a version that uses 'blade' style maxi-fuses instead of mANLs like mine.

Here's (Crutchfield link) the same thing, just one lane; either 1x 1/0 or 4ga on either side, just like the input lugs on the above. I used this to step down from incoming 1/0 feed to a more-malleable 4-gauge for pathing inside the junction box.

The one-laner is in the middle here:

I have a different enclosure coming on a slow boat, but also need to work in my 300A killswitch at some point.

edit:
By using the battery => starter => junction box path you mentioned, I was able to make this ugly donut of cable and starter relay redundant:

tabby for scale:

The big ground is on the other side of the motor now, running back alongside the feed. Both tuck under the rain sill nicely. May trim the ground further to eliminate that loop at the end:

VVVV The way I understand it: A relay is just a switch that's flipped by a signal instead of your finger.

Car audio stuff is the bomb. I use car audio grade battery terminals, with ring terminals on the end of the actual cable, on most of my not-new cars. I can't stand lead terminals any more, especially the aftermarket clamp type.
The car audio market also has fairly high-current breakers that you can use as a main instead of a fuse, which is nice. You can also get cable terminals with built-in fuse holders, as I recall.

I only found out what a relay was because I had a broken one and got bored and then pulled it apart. as soon as I saw the guts of the relay *everything* about car electrics made sense.

Relays are great. Controlling a big, hairy current with a little signal is remarkably useful.
It annoys me now when a car maker cheaps out and runs full motor current through power window switches rather than using relays. It burns out the bespoke $not cheap switches rather than a cheap, ubiquitous relay. I've actually installed relays on the power windows of several cars I've owned. About to do it on my Crown Vic, I think, since the driver's front window switch has a habit of burning up on these cars from use.

You're in Ontario, right? Who are you going to use for the cage build? I'm almost finished with a CCUK FIA kit in my friends 350z if you need help/advice.

I�m surprised by how much you can do with stuff intended to drive amplifiers.

Nah, Central Texas, but I�ll take any advice I can get. Cage is my bext Big Step.

Main-hoop with harness bars with a rear shock tower tie-in (4-point) if you plan to street drive the car, or full 6-point (or 8-point if you want to tie the front hoop into the front shock towers through the firewall) if you plan to always have a hans and helmet when you're driving.

I was definitely hoping to get the front tied in; seems like a good idea on any old car.

Ha, I actually converted my Miata to manual windows because of that. I could have added relays but it was a pain in the dick and manual windows were faster and easier when it started to rain anyways.

Really helps your starter trigger signal (red circles) when you don't accidentally wire it to a bonus circuit (blue circles) because the wires are the same color.

whoda fuckin' thunk

I'm gonna go get gas and ratchet strap the tank down. Maybe test the brakes.

Well, if that isn't the most painful-to-read wiring diagram in the history of cars, I'd like to see what is :psyduck:

FYI: A Bosch 044 will pressurize a fuel system VERY quickly, and you will discover this if your fuel fittings are not tight as can be everywhere.

I've only ever looked at Toyota factory wiring diagrams, but generally this isn't so bad. It's wayyyyy zoomed in on the body and engine room connectors, here's the whole thing if you care to try:

I think he means all the damned crossing lines. That�s incredibly bad form in wiring diagrams. At least that one is in color, which helps quite a lot.
