Not sure yet, like to have a good disk brake setup.




Here's a bit of an update not much but it's one step at a time .

Lashed out on a Westside Exhaust and Custom radiator and oil cooler combo.


Also a PWR barrel cooler, heat exchanger, filler spout and water pump I scored for a good price off ebay.



Now have to make some mounts for the radiator and heat exchanger and plumb up the barrel cooler.

Getting there ever so slowly.

[Stredrotor]

Found a bit of time this arvo, so with the mounts welded on I mounted the radiator and made some trial mounts for the heat exchanger radiator.

Also had a bend welded onto the end of the barrel cooler to bring it in line with the radiator.





Waiting on a 135 degree bend from plasmaman to go up to the throttle body to finish it off the intake side.

.

[Stredrotor]

Shaping the end of the tube to match the chopped off snout.



Trial fit up.



Spent a few hours sanding out the casting marks on the snout and the hammer marks on the tube.





Now just have to get my mate Troy to weld the pipe and snout together. (Don't have an AC tig to do Aluminium)

[Stredrotor]

Hey guys, today I moved the wastegate outlet which fouled on my new radiator .

Cut it off and shortened it........



Then welded it up!




The pipe from the barrel cooler to throttle body now welded.



I made a mount for the coils. I think they should work there .



Here's a pic of the dump pipe, just tacked up at the moment. When I get the lower flange cut and tacked I can see if the flange will fit past the engine and steering box .
Then I can weld that up as well.

Just a quick update guys, with a few jobs around home keeping me busy I haven't had a lot of time on the old girl. So while I am waiting to get a bit of cash together for the stud kit and the rotors to be machined I have managed to sneak out to the shed a few times. Wore my fingers a few centimeters shorted by sanding and polishing the intake manifold and throttle body snout.



Still needs another sand I think to get a few more scratch marks out. It's not going to be any show car but I always wanted a car with an engine bay I was proud of.

[Stredrotor]

New update . Purchased a Xtreme Rotaries side mount alternator kit and alternator with twin pulley.



On the down side now have to modify my coil mount as there is slight fouling on the front coil. Oh well that's what ya get when you buy your parts one at a time.

[Stredrotor]

Bit of an update, I cleaned up the dash, rust converted and primed the dash frame. Also stripped and repainted the steel cover panel.




Also after finally after getting my TIG back (well they replaced it ) I got around to welding the exhaust probe bung in and shaping the dump pipe to give a bit more clearance for the steering box.




Should be able to send it off to get ceramic coated now!

[Stredrotor]

Hey Guys, got my exhaust manifold, dump pipe and turbo exhaust housing back from getting ceramic coated.




The finish is not as smooth as I thought it would be but it looks allright. As long as it holds on an keeps a lot of the heat in.

About half way through fabricating the front crossmember so after Monday I will have a break from my studies for 3 weeks so might be able to get a bit more done.

[Stredrotor]

Fabricated the front engine mount crossmember...






Should be able to pull the engine out now and throw a whole lot of money at it .

Then start paint stripping the engine bay. The fun begins!

[Stredrotor]

A bit more progress!

I have made my rear caliper brackets to adapt the RX7 calipers to fit the Toyota Hilux diff housing.

First I created a CAD model of the diffhousing, axles, bearing and housing, disk rotor and a rough model of the RX7 caliper.


Then I printed a 1 to 1 drawing of the profile an cut it out of MDF.



Then ground out the step down.


When I was happy with the fit I created a DXF file and had them laser cut and had a mate mill the step into them.


And here is one fitted!




I also bought some new rubbers that go top and bottom of the leaf springs. Bought almost the last lot that Mazda had left.

[Stredrotor]

I got the laser cut parts back this week so I started work on the 2 link mounts.....

This is the CAD model.


This is the mount for the chassis.


These are the mounts to go on the diff housing.


And here are they all are with a bit of a mockup.

[Red Baron]

Can't wait to see the end product.

[Stredrotor]

Ok a bit of an update!

Here's my latest investment...


Tremec TKO 600 5 speed with Carbon Syncros, Brass fork pads and with an Ultimate Street short throw shifter, Quarter Master Hydraulic bearing, slip yoke for the tailshaft, a Direct Clutch twin plate, and a Green Brothers steel bell housing.

I have to do a little mod to the box to suit the RX7 turbo starter and fabricate a gearbox cross member, I will detail this later.

[Stredrotor]

Had to make a mod to the TKO to clear the starter for Green Brothers bellhousing.

Some of this area has to be removed and a new hole drilled.


Marked out the material to be removed and drilled new hole.


Chopped! A bit un-nerving on a brand new gearbox


Bellhousing back on. Just need to get hold of a turbo RX7 starter to double check fit up.

[Stredrotor]

Here's the photos of the fit up...


The shifter comes out pretty close to the factory hole. (Already butchered for the early RX7 box when I bought it ) The engine is 50mm further back than factory so normally would be spot on.


Good clearance around the firewall.


Not bad around the trans tunnel either.

As soon as I get the laser cut parts back I'll fab up the cross member.
