Had a relatively busy week with the car.

Last week I sprayed all the cavities in the bay with Dinitrol rust converter and also filled and painted the holes I made when removing the tunnel brace mount.

I painted the ABS bracket and base along with the bolts. Some of it has gone matt though as it was damp outside. Hopefully a polish will bring it up again.



This weekend I sprayed Dynax S50 in to the cavities, then spent a good 4+ hours going over any seams that were missed by the garage (used epoxy mastic). There's a lot of nooks and crannies which makes it a really tedious job, not to mention messy.

Here's a view in to one of the frame rails:


I still need to figure a way of getting the crap out of the cam sensor hole. I may have to blow it down and take the sump off to clean it out. Not sure how much room there is though.



I got a new rear o-ring for the water pump so that can be prepped for paint now.

Nice job ^^

One half of my tunnel looks like that... the other half I was lazy and kept the Mazda matting.

Next job was to sort out all that crap that fell in the engine when I took the cam sensor out.

Firstly took off the sump. Turns out the sump gasket is shot.




Luckily most of the rubbish fell straight on this



Some grit stuck to the crank shaft.



But, after an hour or so I got it all clean. I looked up under the engine and got in there with an earbud taped to a skewer to reach up inside. I then turned the engine 1/8 turn then repeated the process.

After a bit of a faf I got the rear subframe out. It's in a bit of a state and I can't be bothered to spend ages tidying it up so I purchased one that has already been dipped. Hopefully this coming week I will be getting the front diff mount welded in.

I still could do with the height that the standard bushes sit above the subframe mounts. I know that the pinion angle needs to be 2.5 degrees (relative to flat of subframe top), but I want to make sure I have plenty of room to play with.



Also tarted up the ABS pump a bit. I could have done it alot better but fully dismantling it would have been loads of work. Besides, I am not going for a show car finish.

Got some surface rust to sort out under here


ARB, tank straps and fuel lines are all a bit crusty here so will get them cleaned up this week


Got the fuel tank out (I was on a roll). This has some rust in too. Going to get some deox gel to sort it.

Got started on the cobra diff mount. This is going to be a lot of trial and error as the car is miles away from where the workshop is.

So far the cross bar has been bent and spot welded so that I can move it about a little. It is sitting quite proud of the subframe at the moment so I suspect it may hit the underside of the car.







I also started making a blanking plate for the clutch master, blasted and painted the brake servo heat shields (not sure if I will be using them), drilled the blanking plate ready for the tapping a 1/8 NPT for the speedhut oil sensor. Blasted the rear anti-roll bar and the fuel tank straps but these need soaking in anti rust as they got surface rust almost instantly.

I also had to file the middle holes on the Samberg batwings. I don't know if I am just unlucky, but that's twice I have had to modify bolt hole locations on Justin's stuff.

The brake lines that run round the rear subframe also need to be remade as they are a bit too corroded. I blasted the line splitter for them though.

Bit of a fail on the pipe for the subframe. There's no way it will fit in its current shape as it hits the seat wells.

My next plan is to get some pipe insulation of the nearest size an use that to mockup an alternative.

Man is it ever tight back by the diff I couldn't imagine having to make that myself. Will be a bit of trial and error I think. Interested to see how it turns out!

I spent quite some time yesterday trying to figure out the best shape for the mount. I ended up making the frame dog leg each side. I will get pics up of the plastic pipe template if I finish it today.
