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!

ITB Build – Part 1

FINALLY!!!!!!!!!!!!

Started pulling apart my car today, the head is being removed so I can get that ported. The AC, all wiring, intake, strut brace and fuse box will be removed to make way for my custom tucked wiring harness.

I was planning to port it myself but have decided to send it down to Warren Heath Performance down in Melbourne. The head will received an extensive porting job as well as larger oversized valves, stronger valve springs and re-shimmed solid lifters. The camshaft going in will be 280degree duration and 10.5mm lift.

Didn't get too much done today but photos below.


The operating table where most of the work will be done.



Bonnet off, radiator out and headers moved aside.



Valve cover off to remove the head, full port job on the way with massive cams going in.



The AC condenser removed and a pile of parts that won't be going back in.


That's all for today, covered up and put to bed.

G-String Bikini Top

Awesome post title ey?

I've been drooling over Project-G's bikini top ever since I bought my MX-5, was never sure how it would look in person with my "tall-boy" roll bar so I never ordered it. But I recently found an awesome deal that I couldn't pass up, I'm now in possession of a Project-G bikini top!

It's a black top with red-stitching and also came with a carry bag. I've sourced a front bow locally for little money so pretty happy overall =)


w000000000000!!!



Some extra goodies that came with the bikini top. Always love stickers and free lollies 😀


The bikini top shown with the straps, center brace and carry bag.


Hopefully I'll look just as cool 😛


I also picked up some extra tools to make my life easier when I do my braided fuel lines. Just some aluminium spanners so the nice fittings don't get scratched and a hose cutter.

More Parts & No Progress

Blehhh not much progress lately, BUT I have acquired some more bits for the build. Also been talking with a few guys who are also doing the same ITBs and we've found a few more issues with the T3 manifold... The issue is that the TPS is located towards the firewall and hits against the clutch master hard-line. This is not an issue for all the US guys who have the clutch master on the other side of the engine bay (LHD).


So that's the problem... there are possibly two ways to get around this.


So this is a solution that I'm going to test out, it involves taking 12mm off the end and machining the surface flat. So now I can use a banjo fitting that will let me clear the TPS.


The other solution is to use a braided hose like above, not sure if it'll clear the TPS though. Will figure it out when everything else goes into the car.

So when I installed my new KG Works cluster I forgot to mention that my gauge hood also cracked. Was a pain in the ass but I was able to find a brand new genuine replacement :D. Apparently it was the last one in Australia too! Mazda have more on back order I believe.


So it looks amazing! It does't have the shiny finish like my old one but has a more smooth matte look. Will install this later on when I get a new dash to replace my cracked one.

The next part I found is a duct that is used in cars that don't have air-conditioning from factory. Since I'm removing my AC this part is perfect so that I can remove the ENTIRE AC system and still have functional air/heater.


Wasn't able to get a brand new one but Richard at MX-5 Plus was able to hook me up with this used part. Would prefer a new one but this is pretty decent.

New Parts!

Over the last week I've had a few parts cleaned up and also picked up a KG Works gauge cluster 😀


Install photos are below...



So fresh so clean clean.

Since I'm going to be using the later model cam/crank hall effect sensors, I had my NB6 valve cover blasted and powder-coated in satin black. While I was there I also had the shop blast the NB6 water neck too, this will replace the NA6 water neck because I won't be using the fan switch. Megasquirt will control the fans now.

The work was done by Global Powder Coating, price was the lowest I could find and service/turnaround was good.


First step is to remove all four screws and the steering column surround.



There are two more screws holding the gauge hood, remove those and than gently pull the hood towards the rear of the car. It should pop out with little effort.


Unplug the two connectors at the back of the cluster to remove it.


The new cluster installed 😀

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.

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.

Brake Cylinder Brace

After MANY months of development and testing, my Brake Cylinder Brace is ready! The first batch will be priced at an introductory offer of $100 and limited to 40 pieces. Install photos will be up soon.

Before setting out on this project I did some testing on various MX-5s to see how much movement/flex there is in the firewall. The process was quite simple, I sat in the car and stepped on the brake pedal as a mate measured how much the brake master cylinder moved. It was obvious right away that there was about 4-5mm of movement in various cars we tested. The movement/flex means that braking response is delayed, not rigid and more spongy

The Brake Cylinder Brace simply attaches to the brake master cylinder via the two factory studs and anchors onto the chassis. It's designed like a triangle because triangles are very rigid shapes, every side of a triangle reinforces each other so that load is divided. The brace uses these three mounting points to effectively stiffen up that part of the firewall so there is no longer any flex/movement of the brake master cylinder.

The brace reduces brake travel and improves response time under hard braking. The feel is more solid and precise rather than a soft and delayed reaction time. All this from one small brace.

Installation is very straight forward and requires no adjustments. The brace is designed to self tension as you install it.

Each piece is hand-made right here in Australia, everything locally sourced too. Didn't want to risk the quality or consistency of the final product so getting them locally produced was the only way.

The part only fits right-hand drive NA models.

All stock is located in Brisbane for immediate dispatch.
Price includes delivery Australia wide by Australia Post.

$100AUD
