Ok, I thought I better get a thread started on my car. I've lifted it off the Ausrotary site if wondering why progress is so fast.


It's a 1974 RX4 Coupe bought it late 2007 from Melbourne and sat in my sister-in-law's garage untill I got my new shed built. With my wife working most weekends and having to look after my two kids, dosen't leave much time to work on the car so bear with me.
To get things started here's a few progress pics

When I first bought it and the old wreck of a shed in the background




Now with the shed up I have made a start.
Pulling the crossmember out to replace the bushes.




I have got a few things organised though, the engine has been dummied up and I scored some 12mm plate and made my exhaust flange for the turbo manifold and bought some steam pipe bends.




I also lashed out and spent my performance bonus from work on these two.



A Lincoln Electric 180c Mig and a CIG weldskill 170HF Tig/stick :twisted:
Now once the 13b is sold I can go about fitting the 20b and fabricating engine/ gearbox mounts and a turbo manifold.

 

I got a awesome bargain the other day, a bloke at work tipped me off to some 16 inch F90 Simmons at a second hand shop. A bit of bargaining and these were mine for $140.


All 8 inches wide.

Picked up a Microtech LTX12, coils, loom and Eboost from Sam, aka "GTLimited"


Just got the engine in place to work out the engine and gearbox mounts



Time and cash is really holding me up at the moment. I have lost all my overtime in the last 6 months and this was funding the project. My wife is having to do more weekend work so I am looking after the kids which stops me putting as much time into the project. Things are starting to pick at work, so hopefully might get some overtime in the next few months but at lest I kept my job, there was 280 of us that didn't .


For Fathers Day I asked for some kid free time to work on the Mazda, so I got around to doing the old shorten shifter housing mod......


Modified the gearbox cross member to suit the old RX4 one.....


Made some plates to mount the engine off ......




Now I just have to install the engine and box and fab the mounts off the suspension crossmember.

 

RH engine mount now finished



And test fitted.


Should be strong enough :!:

Got the left hand mount completed, sits quite nice 8) .

 

good stuff!

 

Very Nice project, I know your putting a 20B in your RX4 and you put it in the 20B Forum section but you should move it to the Other Rotary Section. There is alot of Old School projects there and you will probably get alot more people giving you the "nice project" there IMO. Hey if you every want to sell those wheels Ill pay triple for what you got them for. I needs some wheels for my RX4 : )

 

Clean 4! Look forward to your progress.

Forgive me if this is a stupid question, but I'm not a fabricator by trade: Is there a reason why most folks seem to use aluminum spacers to take up the depth differences of the various mounting points on the block as opposed to integrating (welding) a steel piece onto the bracket itself?

 

love the photos. i can just tell that this is going to be good! is it safe to assume you're going to keep normally aspirated?

 

I just happened to have some spacers at work that were the right depth so thats what I used

No way it will be turboed just getting some cash together for the purchase.

By the way I'm interested in what you 20b guys are using for a single turbo uprade. I was looking a something like a GT42R with a .90 to 1.0 exhaust, don't want it to be to laggy

 

The dyno sheet in my sig is with a GT4202R with a 1.01A/R turbine housing. Running a 7 psi spring in a TiAl 44mm wastegate with no controller hooked up. It pushed up to just beneath 9 psi and then dropped to 7 almost instantly for the duration. Unopened block.
