So to update my build so far.

Engine came apart. Got ripped off by the original engine builder (Dyson Rotary) but at least there was stuff wrong. The tuner I was paying Ben left work at the workshop I was going too, but is doing this stuff out of work for cash which helps me out alot as he is about the only guy in town that knows enough about them. Things wrong include

All corner seals springs completely flattened
2 corner seal springs in half
1 side seal 2mm too short, had been wearing on the apex seals
Oil control rings were dead, only half of one was found
Corner seal o ring things were all missing
Crack in the housing - repairable
Extend port was barely a port job at all

So this explains why I was only getting 300whp. The car made 90psi on both rotors before pulled apart, but must have been loosing all/most of its compression under load. Ben (engine builder) is getting me a quote on parts for this as he can get them cheaper then I can then thats going to get ordered/built as soon as my tax cheque clears.

Now I'm going to put my list of stuff I need to do to the car while the engine is out/before I get it back on the road on here as I just wrote it down on a bit of cardboard that will probably get lost. Ignore the prices just putting down what it's gonna cost me for my reference and its all in $au anyway.

Parts to buy

Front slotted rotors (ebay $155 paid)
2 front wheel studs and nuts (repco)
Engine mounts (see ben possible poly ones)
Bosch coils and microtech X4 igniter box ($300 ausrotary)
Oil cooler ($462 PWR)
Air temp sensor (mazda)
ECU loom (microtech)
Microtech DASH unit ($500 microtech)
A/C Condenser (Troy $200ish)
S6 Alternater (Troy $200ish) may wait till after rebuild
Engine pulleys (purely cosmetic needs alt first)
Silicone rad hoses (Ebay)
Oil cooler lines (Pirtek, need cooler first)

Parts to make!

Underbody tray

Windscreen washer bottle <---- DONE!

Rad overflow bottle <----DONE!
Turbo heat shield (titanium free from work)
Rad fan shroud (composite, free from work. Unless I put a carbon layer over the top which I probably will that will be $70 for the metre)

New LIM blank off plates (free work, orignal ones done by mechanic were horrid) <---- Done
Exhaust side heat shielding (Probably be 301 stainless from work, titanium if there is enough for me to take without the boss knowing. Going to box off all the exhaust manifold, dump pipe and wastegate up to try and keep engine bay heat down)
Coil mount brackets (need coils first, will be 7075 t6 from work)

Parts to modify

Engine bay wiring (messy as needs to be tidied up)
Brake lines (got bent out of the way during respray, never got reinstalled correctly)
I/C Piping (need to oxy it and ovalise it between the power steering pump and strut tower)
Muffler tip leaking around tip (give to darrell to weld)

Seat mount bracket busted (give to darrell to weld) <---- DONE!

Parts to paint

Parts are painted in gloss black 2 pac polyurethane paint, as it's free i just surface prep it and give it to the painters at work. I don't like polishing stuff so I just paint it all black, was going to go matt, but gloss is easier to clean just degrease and hose off.

UIM <---- Done!

Power steering pump and A/C compressor mounting bracket <---- Done!

Waterpump <---- Done!
Front cover (Need back from ben after OMP part welded)
Throttle body
Throttle body snout

And that's about it for now. I'll put some pics up of the progress if I get round too it. I got alot to do in the next month or so. I'll just update this list as I get it done.
