This was an incredibly fun read today - definitely excited to see where it ends up as a finished produt. Phenomenal work!!

It has been a long time since I have made any updates to this thread, not a lot has happened with the car but I have been collecting some parts and investing in more fabrication tools.

Today I picked up a set of tyres which I will need to have so I can modify the body for the new ride height and make some new panels to suit. These tyres are way past their use by date but I got them dirt cheap. No point buying new tyres unless I was planning to drive this thing some time soon.

I couldn't resist the opportunity to mock up what the car might look like with some wheels on, speaking of wheels, they will be my next purchase.

That thing looks mean! I love it!

Hey guys, a few things have been happening.

To start with I have taken delivery of my new AC/DC dedicated TIG welder. Up until now I have been doing all my welding using a multi-purpose MIG welder that has a lift-arc TIG function in DC only.
Now that I have a welder that can weld any type of metal I can save a lot of money by making my own catch cans, dry sump tank, swirl pots for example. So it has cost a fair bit up front for the welder but over the long run it should pay for itself.

After a fair bit of back and forth with measurements I have also ordered a set of wheels from Japan. The wheels are 18 x 10.5 but I have had to be very careful with the offset because I am in danger of the car being too wide to fit on my trailer. I won't spoil the surprise and say what they are but as soon as they arrive there will be lots of photos. Unfortunately due to Covid they are going to take a fair while to arrive.

The last thing is I have ordered a pair of genuine Subaru rear wheel bearings off the 08 onwards STi to convert the rear end to 5x114.3 pcd. The front RX8 uprights are already 5x114.3 so this has given me larger wheel bearings and a much wider selection of wheels to choose from.

Been following this on NASIOC, didn't realize it was on here too. Your build has given me a lot of great ideas, keep up the awesome work!

Rear wheel bearings arrived today, brand new genuine Subaru from the 08+ STi. Got these to convert the rear to 5x114.3 PCD so when my new wheels arrive I can bolt them straight on.

The front PCD is already 5x114.3 with the Mazda RX8 front uprights.

Next to the old wheel bearings you can easily see the size difference.

Hey guys, Merry Christmas to you all.

I have been modifying the Honda K24 valve cover so that the motor is less tall and dry sump ready. The design is based on the Honda Racing HPD valve cover.

I'll do a more detailed post once the work is done but here is a teaser for now.

I am also hoping to have a gearbox coming within the next few weeks.

Cast aluminum welding is not for the feint of heart. Glad to see you excited about the new Tig.

DIY · 12-26-2020, 10:35 PM

There is a good chance the valve cover will end up in the bin

Clean the shit out of the material before, and pin a 4 leaf clover on your welding helmet. lol

Good thing is that I have a lot of offcuts from the trimming I did to practice with. The welds will be ground smooth anyway so I can do short runs to minimise heat without worrying how it looks. I will use large chill bars and I may even use pulse for even less heat.

I'm sure you will figure it out. With aluminum, If I can get away with using alumiweld, I'll use alumiweld rods and gas. Its more like brazing than welding. Though I sense you are not looking for a easy way.

Some exciting news, I finally got a trans for the car! It's a ZF 5 speed S5D 320Z from a BMW. Good for 320Nm of torque which should be plenty behind my turbo K24 engine. I weighed the box at around 37kg (82lbs) which is rather light considering the strength, its very compact too.

Now I just need to get an adapter plate and I will be able to get a lot more fabrication done, engine mounts, trans mount, steering rack mounts etc.

I did some test welding yesterday on some of the scrap cast aluminum I cut off the valve cover just to see how it welds and how well it might clean up after with a flap disc and file finish.

It was not as difficult as expected so as long as I can manage the heat I have a lot more confidence in the project now.
