Assembled the engine, with no issues at all. From putting the front plate down on the assembly table to bolting on the rear counterweight it took only 4 hours. The assembly was done by myself so used a car jack to set the e shaft height to get the center plate on. Turns overs nicely with all pulses sounding even. Photo quality is a bit average, my hands were covered in oil the whole time.

Thought getting this center plate on would be a bit tricky, but it pretty much fell into place.

Set the endplay, was able to use a spacer i had laying about which was easy.






Gave Cosmo #1 a wash and took it for a drive

Using an Xtreme Rotaries ewp adapter with -20AN fittings, really nice part all cnc machined.

I purchased a 1200mm x 400mm plate of 6061 T6 to make the transmission adapter and oil pan out of.






Its really heavy, weighs about 33kgs.




The plate is 1 inch thick which makes it difficult to cut on a band saw. I used a 64 tooth carbide tipped circular saw blade designed for aluminium. To make the 400mm cut above it only took about 3mins.




Getting the plate to thickness for trans adapter

Cut a chunk off the transmission flange.

Magic. Puts it into perspective how long it is with the tranny bolted up.

7rotater

Cheers. The funny thing is that its not actually that long. it just appears to be long, the engine is about the same length as an ls1.

Not f#cking about ah ya, well done, great progress

Because the car is so light now being completely stripped out the suspension was sitting way too high. So purchased some D2 adjustable coilovers. Fitted them in about 3 hours with no issues which was a surprise.
They are made in Taiwan but the quality seems good. Not really too many options out there for Cosmo suspension. By the way the wheels are Work Emotion D9R 18x8.5 +38 front and 18x9.5 +38 rear. Front tyres are 235 Goodrides haha and rears are 255 Nitto Invos.




Towed the car out of the tent with the mighty Honda.

Aragosta makes coilovers for us, if you ever see a used set in good condition I'd highly recommend getting them. The set I have now are 4th different set of brand coilovers I've tried and they are phenomenal.

Haven't really achieved much on the 4 rotor. Been busy fitting a new turbo to my rx7.




Started making the sump. Used building paper as a template which wasn't the best idea.













A few of the holes required a bit of massaging, but overall turned out good. Still need to machine out baffles and oil pick up points.




The engine bay of the rx7. Its a 1986 FC. Extend port, garrett gt3582r. 360rwhp. First rotary i have built, 20000kms later still going hard.

Finished the final shape of the sump







Started to make a bracket for the alternator and oil pump










Ended up with a giant swarf pile.

More progress on the bracket

I only have one question. Is your house also built out of giant thick plates of aluminum?

Great Fab work. Carry on.

Awesome and inspiring work mate.
Well done.

Bitchn7

Awesome build mate !! So love it. This si the very reason I haventsold my 20B JC yet. Wish to do a similar thing one day, such a perfect car for a 4 rotor!!

Love the work your all doing yourself too

7rotater

Thanks mate. Don't sell your Cosmo, hopefully Cosmo prices will start going up in the future when people start realizing how rare they are getting. Its just cool doing something a bit different. Whereabouts in NZ are you?






Start of the engine mounts. Will bolt straight to the foward subframe mounts.

Bitchn7

I'm in the Waikato. Had my car for over 10 years now I think. Was bought into NZ new in 91 by Mazda.
Sold the 20B, but have ideas of what i can do with the beast.

Bending the engine mounts, bender is bolted to the forks on the forklift.
