Some more progress today 😀
Had a friend come over to help strip out the interior since my cracked dash and ripped carpet will be getting replaced. Also makes it easier to get out the old wiring harness. Enjoy the madness below, sorry for the lack of photos.
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.
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 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.
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.
My new fuel rail finally arrived, had to replace the M-Tuned rail because it had clearance issues with the fuel rail bracket. And I was able to get myself a B6 cylinder head for free. This allows me to test fit all the parts and I can work on the fuel lines and wiring while my NB6 head is away for porting and cams.
Also did a quick test fit of the ITBs to see if there are any issues that need to be sorted out.
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.
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.
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.
Follow on after the break to check out more photos.
So I'm still waiting for the paint to dry on the ITBs, going to be a long 7- days... But I couldn't wait so I did a dummy fit of the trumpets (velocity stacks) on the ITBs.
I'm so WET with excitement!
