DAY SIX: (6/1/11) FRONT END and REAR END BEGINS
Overnight the POR15 paint dried and I was able to handle the components. I like the finish you can achieve with nothing more than a brush, but getting the part clean is critical. It comes up like a glossy hard enamel and should endure well on the underside of the car. There is no need for it to be a show pony but since the actual car is so shitty looking, all the safety items looking like they've seen some love doesn't hurt.
The photo demonstrates the difference between the OEM bush and the new Nolathane replacement. The boots give the appearance of a new ball joint. It will however need to be greased up like a scotsman. The bushes for the torsion bar (castor and D bush not pictured) are second hand but useable.

And the master was stripped cleaned and re-assembled for a second time. There may be a third with and actual re-kit it for peace of mind but since i still have to make a trip to Darby's brakes I can afford to wait a little. Then do hard lines, pads and calliper kit in one go.
I see there is a little curiosity around the driveline. I mentioned earlier i had a 9 inch as a diff option. It came from a fucked out RX5-121 i scored on ebay for peanuts at the end of 2009. I gutted it completely in a day. It gave up a new 13bPP, RX5 box and the 9 inch diff.
The diff is physically the same width as the RX4 diff (1410mm). It runs a 4.88 LSD centre, no idea on spline count, commodore stud pattern and brakes. It was built by RUPCOL diffs (that's the red stickers).
To double check the fitment complete with some MooMoo chasers running 225/60/15's here it is shoved under the rear 1/2 of the smashed coupe...although not centred properly.
I tried to sell this a few times but got a couple of fuck arounds and no serious takers. To set it up for RX4 it just needs the RX5 mounts lopped off and conventional spring platforms welded on. I think a couple of the mounts may be re-useable as a ghetto 2-link. Can supply a bare 929 housing to make a jig so the job should be easy enough if anyone here wants to attempt the job (for PF cred and man love at bbq) it would be mucho appreciated to keep the costs down. Geelong Differentials are on holidays as is McDonald Bros.
Speaking of which...the 2 link install pics here ----> http://www.mcdonaldbrosracing.com.au/2linkkits.html
are showing the fitment on an RX4. I think I could do it similarly but not the same by picking up the mount points for the cross bar/loop from the front spring eye pivot.
Here is a shot of the underside showing where you could run a bar across (notwithstanding exhaust clearance).

It could be a complete bolt-in. Arms would be donated by a visit to pick-a-part armed with a tape measure. Then cut and shut some adjustability into them. Then make the front pick up brackets. All sounds easy but this won't be happening for a while yet. In the mean time it will be lucky if the old tramp rods go back on.
There is a different way of doing the 2-link and that is the original way as was done on the top of the line JDM RX4 luce. Basically it had two upper arms going to a removable mount on the rear chassis rail forward of the shocks. For those interested there is bulk info here on AR -----> http://www.ausrotary.com/viewtopic.p...t=rx4+handling
The 13bPP out of this RX5 was the main point of my bid.
The seller told me when i went to look that i was the only person who seriously enquired and actually came to look at it. I then found out this motor cost in the vicinity of $8k from Rank Rotary in 1998 or thereabouts. It has brand new from mazda everything bar the apex seals which are Ianetti ceramics, but they are brand new too. The motor was set up in the car with injection, wolf 3d and M&W cdi but never ran. It was well sealed and still full of oil/petroleum jelly as this pic shows.
I'm not a huge fan of the PP. I very nearly stripped this motor to sell as a set of ready-done PP housings and plates. Then plan was to get Jed Simmons to port up a set of BP plates (if you have never seen his work, trust me the bloke is at the top of his game and has close ties to Rohan @ Extreme).
But with no desperate need for the cash, and a very decent 230 odd hp BP motor sitting there already, I shelved any plans until I had a firmer idea of the perfect driveline for my genuine RX4.
And as I have posted, can't rule any combo in or out until i have crunched the numbers and competed honestly by actually building the car.
Tomorrow the block comes out of the RX7 and an auto comes out of that munted RX4 which looks like it was hit by a road train.
