Most of them splices/splits are for ground, power and headlight wiring.

My wiring doesn't have alarm so not sure how that would be wired up.

That wire is close to the fuse box just under the dash, and from memory that wire is for the indicators.

Nice work MrPham!

A question on that window air vent : could someone get it off the window just by pulling it ?
Just like you I could use some more airflow in my car, but I park it on a public car park, doesn't want anyone to mess around with it.
Wondering if a big o-ring seal can be added to keep water out, and a spring split pin could be used to secure it closed.

Keep it up, your build and attention to detail is inspiring !

Thanks mate!

If someone really wanted to they could break the bend the vent and pull it out. It's not too easy though, but one way to make it even harder would be to install a rod on the inside so that the vent cant be removed from the outside. It's a good upgrade because it flows so much more air.

I can't picture the rod you're referring to.
Would you have a link to share for the vent ?

I've seen those vents before, the one that can be secured, but wasn't sure how effective their flow would be.

Also regarding water sealing, mine does fine even through heavy rains or the car wash. No leaks at all.

Build Update - http://omgpham.com/build-update

Not much has been happening but some updates for the build so far.

I received my first batch of Brake Cylinder Braces, so took some photos of what it looks like installed. It's too hard to take photos of the install, so will be doing it on a bare chassis in a few weeks.


Excuse my dirty engine bay.

I've also decided to ditch the old style CAS and go with dedicated crank and cam angle sensors. They're used in later model BP4W engines as well as NB6 engines.

Started my ECU harness too. Re-used the ECU connectors and just de-pinned the terminals so I could solder new wires on. Was a tedious process but well worth it, sensors/injectors/coils connectors will be installed later.


mmmm so fresh so clean.


Cleaned up all the connectors that I plan to re-use, de-pinned and bought new rubber seals.

Picked up this cool passenger foot well plate from MX-5 Plus. No idea what brand it is, but it looks useful as it'll give me more space for the MegaSquirt and fuse/relay panel.



Made a decision to get rid of the of standard coil/ignitors and go with the very popular "Toyota COPs". Coil-On-Plugs provide a much better spark as well as giving me sequential spark with the MegaSquirt.

ITB Assembly - http://omgpham.com/itb-assembly

The enamel paint on the ITBs finally dried, didn't air dry in 7-days like the instructions said. And I actually had it in the oven for a total of 12-hours at 60degrees. That was annoying...

Anyway, I had some time today so I went for a drive in search for new throttle plate screws. The factory screws are M3 which are "mushroomed" from factory to stop them from ever backing out. I drilled these out so I could pull apart the throttle bodies for sand-blasting and paint. Checkout the photos here - http://omgpham.com/itb-strip-clean.

The shop is called Small Parts & Bearings, they stock a huge range of screws and taps. Had a chat with them at the shop and they recommended the M3.5x0.6 Hex Cap screws. I bought the required tap too, total was $18. Not too bad I thought.


First step was to drill out the hole slightly and then tap the new thread.


Just test fitting the new screws, had to cut/shorten the screw too.


The assembly station, used a syringe to apply oil in the tight spots. Also picked up some spare ITBs for parts, was great having them there so I could check how everything went back together.


One throttle body done, three more to go.


All four throttle bodies assembled!

This next part is a bit hard to explain, but basically the Toyota throttle linkages don't really match up with the stock Mazda throttle cable. There's a bit of slack as well as not enough travel in the throttle pulley. The idea is to make more space between the throttle cable stop and the throttle linkages, this removes any slack in the cable. It's quite straight forward to do, just have to move some parts around so that the throttle linkages sit on cylinder #3 and #4 instead of #2 and #3.

After re-assembling the throttle bodies, the service manual outlines the procedures to adjust all four linkages that "daisy-chain" the throttle bodies together. I'll do that in the next couple of days hopefully.


I can't wait to get these on the car!

Nice work !
One comment on the screws you used though : the head is quite large and will generate some aerodynamic troubles.
I own a Mini. Carburetor tuning include shaving the head off (not entirely) and reduce the shaft thickness. Can you get some different screws ?

Those AE itbs are coming along nicely! What fuel rail are you going to use? Injectors? throttle linkage?

Thanks mate. Took your advice and got new screws in, will show you photos soon.

M-Tuned rail, 1.8L injectors and not too sure about throttle linkage setup yet. Will update as soon as I figure it out.

ITB Update - http://omgpham.com/itb-update

In my previous update I posted up about reassembling my ITBs. I had to use new screws to hold the throttle plates as the old ones were drilled out, they were replaced with socket cap screws but I was recommended to use something with a smaller profile head. I've now replaced the screws with button head socket screws.


The screws were also cut down so not much thread was left sticking out on the other side.

Spent some time over the weekend dialing up the ITB adjustment screws, still a few things to sort out and hopefully they won't cause issues down the track.



Stupid little adjusting screws, very tedious!


Finally received my FPR adapter piece for the M-Tunes fuel rail.


Gave the foot-well plate a good clean.

(have you put loctite on the screws ? You don't want one to kiss a valve )

For sure, used loctite on all throttle plate screws. Backed them in and out a few times while the loctite was wet just to make sure all the threads received a good coat.

Wiring Update - http://omgpham.com/wiring-update

Small update... some wiring parts arrived and picked up a white board to help me scribble down wiring stuff. It's been pretty handy



According to the MegaSquirt manual, it's a pretty good idea to shield the TPS and trigger wires. So have been on the search for a flexible 2-core shielded cable, ended up deciding on a microphone cable from JayCar (part no. WB1530).



Terminated the shielding into it's own BLACK wire, this will grounded at the ECU end and left floating on the sensor end. The BLUE wire will be used for sensor return and the WHITE for sensor ground. The +5V/+12V wire will be run externally to the shield.



My awesome PURPLE (and grey) Deutsch connectors, all solid terminals too.


This is the relay block I'll be using, it's all modular so you can expand if needed.

Engine Harness & Wiring Parts - http://omgpham.com/engine-harness-wiring-parts

So a few weeks back I started working on the ECU/engine harness, this was re-using old connectors and terminals. Was never happy about re-using those parts...


How it was with the re-used parts.

Fortunately I was able to find the part numbers for new parts, all sourced locally from RS Components too! All parts are manufactured by Tyco/AMP and the part numbers are below:



I also found a very good source for automotive wiring in Brisbane, the company is CECA and located in Geebung. They stock Tycab's full range of automotive cabling.


All new connectors and terminals!



Also started on my Deutsch connectors, love these things!


All terminated... this connector is used for all coil and injector +12V wires.


As a precaution, I also did continuity checks for every wire and terminal used.


These are the parts I picked up to do my dedicated fuse/relay panel. Includes terminal bar, bus bar, fuse block and a relay block.


On the left are the brand new terminals I used, and the right is the FD RX-7 battery fuse block. This is where I'll be relocating all my main fusible links, sits on the positive side battery clamp.
