That’s not a mod.

 

New update time.

First off, I won the "People's Choice" Award at the 2016 All Japanese Day. So happy!

20160703_125123

A few small updates to the interior.

20160520_13110620160519_233503

Push button start installed in the factory cigarette port, Jass Performance shifter boot, and my new Hazard Switch Kit.

20160713_090825
20160708_10222620160713_090037

This was a custom turned part my friend made for me. It's pretty much a quick connect fitting into a barb adapter. And it's used for my temporary idling setup.

20160709_10595320160709_110751

Had this piece laser cut out of aluminium to mount the modification and build plates.

20160706_112651

I also managed to install the Pipercross C604D air filter. The adapter plate was a custom one and the filter is offset towards the front of the car by 10mm, this was done to clear the clutch master cylinder and reservoir.

20160709_11074020160712_11265720160712_112722

And there's very little clearance, so I need to find a more compact clutch master and reservoir solution soon.

I've had side skirts on my car in the past, but I removed them because they always seems to go wavey after awhile. This was using the skirts made from ABS plastic, but I'm pretty sure the polyurethane ones will do the same. Fibreglass ones should never go wavey, but the fibreglass ones I bought ages ago were wavey out of the box. It seemed like they were moulded off a set of wavey ABS ones.

So these are some new ABS plastic ones, but modified. I had some aluminium sheet (1.5mm thick) laser cut, and folded one side to give it some rigidity. I then wire brushed both surfaces to roughen it up, and a polyurethane based adhesive was used to hold them together. Lots of clamping...

Hopefully they'll hold up, will update how it goes after summer!

20160713_094953
20160713_09492520160714_095719

Side skirts installed!

Now the first job before installing your new Hazard Switches is to remove the tombstone. I won't go into this step because there are dozens of tutorials that already exist online. The YouTube video below is pretty good.

This is how you'll receive the kit, comes with the "plug & play" harness, switches, panels and brand new omgpham.com sticker.

20160710_163445
20160710_163605

Take note of the labelled bags and the markings on the face plate and switches.

20160710_163840
20160710_16392620160710_164051

Install the switch marked "R" in the top position of the face plate, and switch marked "B" goes in the bottom position. Switch locations and orientation are marked on the back of the face plate.

20160710_16413820160710_164234

Once the switches are in, you can go ahead and install the backing plate and carefully tighten the nuts until finger tight, making sure the switches and face plate are in position. Once the nuts are finger tight, grip the switch housing and rotate counter-clockwise to further tighten down the switches.

20160710_16430520160710_164556

The connector labelled "R" plugs into the top position, and connector labelled "B" goes into the bottom switch.

20160710_16473220160710_164814

And this connector plugs into the factory wiring.

Manifold Vacuum Rail

 

OK! So last post was positive, engine started up, ran well and idled nicely. But that didn't last long...

While getting the tune sorted, I noticed that the vacuum readings were a little off and it turned out to be a vacuum leak due to a hose not being connected properly. Fixed the vacuum leak and then the engine didn't want to idle anymore... So I fixed the idling issue but that resulted in my brake booster not getting enough vacuum to assist the brakes 🙁

So the real problem was the vacuum set up, I think. So I've come up with a set up that mimics a few other off-the-shelf ITB kits. Haven't had time to finish everything yet, but will post update when I get it running again and report back on the vacuum set up.

20160216_173342

These are the push-to-connect fittings I'm using, swivel tee fittings.

20160216_17333620160216_185723
20160217_132048

Marked out the holes and drilled 11.1mm holes so that I could tap a 1/4" NPT thread.

20160221_18204720160223_140507
20160223_142052

The fittings tested fitted and measured so I could cut the hoses. The hoses need be installed in the fittings while they're out.

20160223_14302220160223_143032
20160223_143741

Vacuum rail installed and the old holes plugged up.

20160302_17250520160302_172516

Also test fitted the filter backing plate, some clearance issues here...

20160305_114422

Installed a Garage Star Wiper Cowl panel, and need to make a new fuel hose because I had to go from dual to single feed fuel setup.

20160302_182739

And finally installed and gapped the headlight covers, hate doing them so much.

28Dec/151

Start Up!

 

This was not a smooth start up.... Ran into a few issues earlier on, car would crank over and sometimes nearly run but never more than than a fraction of a second. Went through and checked through the wiring and grounds, everything was good there, a quick visual inspection of the cam gear and cam lobes to see if they were in the right positions. And a whole bunch of things....

The ECU logs showed consistent sync loss, error no. 31. Something was wrong with the cam/crank sensors. In my particular case it was caused by the crank trigger wheel being installed backwards :P. And I actually did check it earlier on, but checked it incorrectly!

Once I flipped that trigger wheel around, it started right away! Here's a quick video of it, more to come later!

Back From Holidays.

20151025_194910

After the last update, we went for a short trip. Then there was the house move.... So not a whole lot has happened with the build, but still some steps closer to start up :).

I finally received my laser cutting order, the original holes for the wiring have been blocked up and the bulk head panel is done too. All three pieces were painted with a clear-over-base rattle can paint system. Turned out pretty good 🙂

Would also like to look at redoing my brake lines at some stage.

20151122_16571220151124_122953
20151203_140402

This is the Jass Performance shifter boot. They're a direct bolt in part with a much more durable boot than the Mazda item. My brand new Mazda replacement lasted just over a year. Will be doing a group buy soon for these 🙂

Interior back together.

20151201_214204

Borrowed a friend's Pipercross air filter for testing fitting. These have an internal height of 120mm I believe, more than suitable for my 75mm velocity stacks.

20151206_134402
20151206_13441020151206_134339

But the problem is that it doesn't clear the clutch master cylinder and reservoir. I'm currently talking to a few people with some possible solutions, more info when that's sorted.

20151206_13441820151206_134333

And had my HKS headers ceramic coated by Thermal Edge Coatings.

Door Cards & Other Bits

 

Some more progress over the last few weeks.

I installed new door cards and door pull. The door cards are by CarbonMiata and door pulls by Jass Performance, both products available through my store. I also went with some larger diameter speaker grills, I think it works well with the rest of the interior.

20151018_11320320151018_113210
20151018_113158

The interior wiring is now completed.

20151015_232306

Rear lip was painted gloss black and finished mounting that up.

20151013_122824

I used some rubber sheeting to make a gasket for the bulk head connector panel, cost a couple dollars off eBay. Than used some spray on glue to position it on the panel.

20151016_22300020151016_223643

In a previous post I mentioned I had to make a jig to mount my throttle bodies, well below are more details on this. Quality of the T3 manifold isn't the greatest. Basically because the T3 manifold doesn't have dowels and the throttle body mounting holes aren't in the correct positions, the throttle bodies were never perfectly aligned. This misalignment results in the butterflies not opening evenly. I confirmed this with a spare set of throttle bodies.

No matter what adjustments were made, the butterflies would either be out of sync at closed throttle or part/full throttle. Even adjusting the bypass screws wouldn't help.

Not too sure how important it is to have them open evenly, but it can't be a good thing if they're not...

Below shows a factory Toyota manifold with two locating dowels on each throttle body.

20151007_215107

Throttle bodies mounted to the Toyota manifold and everything dialed in.

20151007_210341

The jig mounted to the throttle bodies using the top holes.

20151007_210651

Throttle bodies unbolted from the Toyota manifold and transferred to the T3 manifold. The threaded holes in the T3 manifold were not spaced correctly so I had to drill out the holes in the throttle bodies to get everything to bolt down.

20151007_211147

Jig plate removed from the throttle bodies and trumpets installed.

20151011_002801

Intake mounted up and injectors connected.

Wiring Complete!

So here we are, all done.. All those early mornings before work and late nights after work building the engine harness and tucking the body wiring. Pretty happy overall with the finish product, just a few changes I will make later. Just want to get the car running for now.

The 3D printed plate will be replaced with a laser cut stainless steel piece.

20151007_185217
20151006_23062420151006_000843

Engine harness complete!

20151007_15450520151007_154458

Dummy fitted the intake so I could cut the injector wiring to length.

20151007_13181420151007_093744
20151007_185309

The start of the ECU side of the engine harness. All this is being recycled from the previous wiring setup. So handy having everything done with Deutsch connectors.

20151008_195102
20151008_20114720151008_204113

The washer bottle has been relocated to under the guard, I think it should clear everything on full lock and compression. It's a bit awkward to refill, but probably only needs to be topped up once a year. This washer bottle is from a Holden HQ I believe.

LOTS OF PHOTOS. Wire Tuck.

 

OK, a decent update. Lot's of photos.

Because I'm planning to use bulkhead connectors on the firewall for the engine harness, I drew up this plate to mount the connectors. It allows easy disassembly if any changes need to be made or replacing connectors etc. Because I'm recycling parts for this section, the connectors used are Deutsch 12-way DT and Deutsch 31-way HDP.

Had it 3D printed so I could start the wiring while I wait for the real thing to get laser cut from stainless steel.

Installed these Garage Star Fender Braces too. Pretty straight forward, comes with all new stainless steel bolts.

20150924_20262420150924_202639

Because I had the valve cover sandblasted and painted, all the baffles need to be removed so the blast media can be cleaned out. Garage Star machined stainless steel valve cover bolts. I've got a whole engine bay dress up bolt kit to go on too.

20150927_10580420150927_105808
20150927_163726

Started on the body wiring tuck, wires are coming out of the side behind the front guards. This has been drilled, painted and sealed to keep moisture out.

20150928_09142620150927_224049
20150927_22185520150927_221633

Slowly cleaning it up and routing. I've used loom tubing for exterior sections, they provide more protection than just braided sleeving alone.

20151003_00400620150929_111820

The wires re-enter the body from the side, drilled a 24mm hole and than sealed any bare metal. Ideally I should have done all the cutting/drilling before paint, lesson learned. I also picked up these wiring grommets from Clark Rubber.

20150929_11250920150929_102632
20150929_105156

I've had to make a few extensions to tuck the body wiring. Instead of soldering, I've been using these uninsulated butt-splice crimps and than heat-shrinking over it.

20150929_09411420150929_105017

Using a factory hole to tuck the wiper motor wiring. I think the hole is normally used for the washer hose, but I'm relocating the washer bottle... More details on that later.

20150929_09213420150929_092201
20150929_101704

These exposed wires have been wrapped and loom tubed now. Interior sections are covered in a braided sleeving with heat-shrink on the ends.

20151003_00404420151003_004229

The headlight assemblies back in, most of the wires are out of sight.

20151003_11394520151003_113929

The dual horns installed, and the body harness is done!

20151004_003032

Just so everyone knows, this part of the build is on a strict on budget, won't be MIL Spec or anything like that. Every part was either given to me for free or simply re-used from my old harness. It'll do for now, and I'll look into doing a concentric twisted MIL Spec harness later.

Below is the wiring for the coils, it is being terminated into a Deutsch 12-way DT connector. This connector contains wiring for the coil triggers (x4), coil power (x4) and the ECU grounds (x4).

20151004_23520620151005_002610
20151005_00151420151005_02175020151005_021800

For shielded wires (TPS, crank and cam sensors), what I did was strip the cable further back and unbraided the shield. I than twisted it up and heat-shrinked. It gets terminated into the bulk-head connector and continues onto the other side.

20151005_18024620151005_180338
20151005_180853

Finished the crank and cam sensors. This is all a dry fit, once I have it mostly sorted, the wires will be sleeved and heat-shrinked.

20151005_18511820151005_190646
20151005_181235

To tuck the starter and charge wires, I had to a slight extraction and feed them through the tunnel.

20151005_10394920151005_130146

So my ITB manifold is shit... The factory Toyota manifold has two dowels per throttle body to locate everything into perfect alignment. If the throttle bodies aren't correctly aligned than they don't open equally no matter how many linkage adjustments are made, not great at all!

Below is my solution. I mounted my throttle bodies to the Toyota manifold, adjust everything and confirm their alignment. I than bolt the tops of the throttle bodies to a thick plate of steel. The throttle bodies are removed from the Toyota manifold and transferred to my Techno Toy Tuning manifold. DONE! Everything is spot on now.

20151004_22481320151005_191239

Many late nights...

Back Home!

 

Happy day! Car has been towed back home and first thing we did was remove all the front panels 🙂 Storing them in a spare bedroom for now, don't want to scratch anything during assembly.

20150923_07251920150923_095301
20150923_100844

Colour is Audi's Aviator Grey.

20150923_100837

The entire engine bay was covered in blankets during the engine install.

Hnnnnggggggggggg!!!

20150923_14115920150923_141152

Colour looks amazing in sunlight, the Audi paint code has a bit of pearl through it but can only be seen in direct sunlight.

20150923_14122020150923_141215

Paint Shop Update 7

 

Awesome day today!

Most of the panels are secured onto the body now but only a few things have been gapped properly. I just really wanted the panels back on so they could be towed home securely on the body instead of strapped down behind a ute.

The flow coat came out amazing! The guys at J&D Quality Smash Repairs usually give it a polish too, but I figure it would be best to do that after I finish assembly. A few little extra bits need to painted and both windscreens need to be fitted up, but that's about it and I should have the car back mid-next week.

A pretty cool Lotus Elise was in the shop too 🙂

20150917_11043420150917_110457

Installed the boot lid, rear bar and than rear garnish. These panels have been gapped properly.

Using brand new bolts and flanged nuts with washers wherever I can.

20150917_12322520150917_123952

New rubbers 🙂

20150917_11350220150917_114345

The doors/rocker panel have had their rock-guard removed and everything smoothed out. I've kept the black section though, it's gloss black and will go well with the lips/sideskirts that will also be gloss black.

20150917_150305

Bonnet and front guards are on but not gapped yet. These panels will be removed as soon as I get the car back though, keep them safe while I get the engine and wiring done.
