Seems fair enough mate, not everyday you get someone offering to freight your car down free of charge. However it is interesting how he apparently has no ownership of the business or gets wages from it..... oh well.

woah, what a read and a half!! Apart from that one twat, its good to see most people on there are trying to help you figure out the issue rather than flame you

Good luck with it and let us know what happens

Yeah well I'm waiting on dysons to clarify a few things. And mick 2 of those guys have been working on the car with me. Ash and i tried a few things today, took the muffler off the back and took it for a spin. Maybe gained 10hp or so nothing massive. So came back disconnected my BOV and hooked my boost gauge up to it. Im getting a pressure drop of around 7psi through the cooler. So i ordered a new cooler and am going to make all new piping out of 3" stainless this weekend.

3" piping is pretty big for cooler piping I thinks. 2.5" max is what most people recommend. Could also be a silicone hose with a tiny split or hole in it. Never know.

Good luck with it though. Hope it works out well for ya.

Cooler piping size all depends on the desired air flow Bob, 2 will work to a certain flowrate/power and so on and so forth. 3 inch isn't too big I'd say for the kind of power Chris is aiming for. I've got mates with 3.5inch inlet and 4 inch outlet cooler piping on skylines making big big power.

Yeah dysons reccomended 3". My cars really giving me a headache, having a hard time working out whats wrong with it. Hopefully something happens when i get this new cooler in. If not its getting a compression test which im sure will say fine then heading back to dysons

You mention the motor is an extend port, built strong with only 20000km on it, how sure are you of this? Where did you get the motor from? Did you get it built yourself?

I would not be being so specific if i didnt know. I have a reciept for the engine being built by them in my name.

Aaahh so you did get it built yourself. Good stuff I was just hoping you didn't buy a motor under the proviso it was recently built and get stung like so many others. I was told my old motor was a 4 bolt mains group A block and it was just a dirty old 308 block lol.

Well i did get stung when i got the car, it had a "rebuilt" engine in it. Blew up a month after I got it. My new intercooler just got here, seems pretty decent. Now i just gotta start making some brackets up at work on monday to fit it, and get some cash to buy the pipes.

Got any updates on this Chris??

Yeah im just in the process of making up the intercooler piping. New cooler is dearer to install then one would think so far ive spent

Cooler - $240 shipped
Stainless pipe - $250
2.5" - 3" silicone elbow - $75
Throttle body adaptor - $175

Ive made up the hot side of the pipes, just waiting on the throttle body adaptor to arrive so i can make up the cold side, should be fairly straight foward. Had to cut alot of puppy out of the front of the car to get this all in lol. I still gotta work out where im relocating the aircon filter too. Then i gotta wait for pay day to buy the rest of the silicone couplers and all the clamps for it. I'm just taking my time with it lol kinda over the car at the moment a little

Dont even worry about the Aircon. I took it out of mine to fit a bigger cooler. Who needs it anyway the power sapping puppy that it is. lol.

Haha i dont use it at the moment, but I like the idea of keeping it so im gonna try.

Ah god damn, got my new 3" throttle body snout today, got a straight one so it would look neater i gotta cut the oil filler neck down. But now i gotta relocated my trailing coils lol.

So i figure I'd update this with what I have done.....

Intercooler (600 X 300 X 76) Is now installed
3" piping from turbo to throttle body snout is in
Engine has been compression tested, just over 90 in both rotors
Coil packs have been changed
Have tested with air filter off
Timing has been checked
It's also now a 2 seater.

And it still doesnt make any more power =(

In my quest for horsepower this is what it has come down too. Will hopefully start tearing it down this week. Am also doing some mods whilst I'm at it. Buying a sheet of 6061 tomorrow as the stuff from work doesn't weld real nice so I can make a radiator overflow tank, windscreen washer tank and hopefull a tank for the water injection I want to be running in the near future. Am also going to rewire the ECU so all the dodgy crap wiring that plugged into the std stuff thats long gone. Gonna paint some of the other bits black too like the timing cover, power steering pump and ac mount bracket. Also making a carbon fan shroud up for it. Gonna be a busy month or so.

Woah...sounds like you're on a mission bro. Can't wait to see this unfold

Yeah, just working out funds. I have to buy a new ac condensor and I wanna look at a PWR oil cooler as they do a bolt in replacement. Just trying to work out all the hidden costs, I wanna replace all the radiator/heater lines and such as I dont want a stupid hose being what kills my engine haha.

Anyone know how much it is to get an exhaust manifold HPC coated?

Wooo, engine was pretty buggered. couple of cracked seals, corner seal springs were dead flat so this thing would have had next to no compression under load, as a result of the overheating with that stupid radiator incident I only had half an oil control ring instead of 2. So basically the problem is found, this thing is gonna haul when its back on the road. Finally

Always great to solve problems.

Haha had a win today! Won some RDA slotted front rotors for my car for $130!!!! Good old ebay.

Anyone one here running a microtech and wanna buy a hand controller for 100, looking at upgrading to the dash unit.

Stole my post off rotary car club, cause i really cbf typing out the list again. I'll update as I do it.

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
  
• Rad overflow bottle (sheet of 5051 for these 3 $160 Capral)
  
• 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)
  

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.

now thats an xmas wish list if i ever seen one hahahaha
