Pork Chops Posted 26June, 2017 Report Share Posted 26June, 2017 Might be a repost but my first car was an RX4 with an extend port 13b. Pulled 140mph and blew flames on up changes. Otherwise was a shocking car! TG911 and JV911 1 1 Quote Link to comment Share on other sites More sharing options...
firstone Posted 26June, 2017 Report Share Posted 26June, 2017 Rx4 was my intro to real speed. Also extended port 13b. I spent hours port matching both ends of the inlet manifold and adaper plate and sat a 465 holley on it. Too tight to spring for a 48IDAPlenty fast enough ATT. How I'm alive is any wonder. What a DH ? JV911 1 Quote Link to comment Share on other sites More sharing options...
DJM Posted 26June, 2017 Report Share Posted 26June, 2017 Amazing how the rx2 coupe shape just looks good in primer grey without windows. i feel bad, I personally witnessed the destruction of three rx2s (2 sedans, 1 coupe) and 1 rx4 coupe.None were actually that bad, but it was uneconomic to fix even a mild shunt then.not any more, RX2 coupe on Ausrotary page on FB in neat enough condition with a 12A not in the car and in need of rebuild..............$45k!

DJM Posted 28June, 2017 Report Share Posted 28June, 2017 How about a stock RX2 sedan with bare metal respray for $110k......can't figure out how to post a link but if you want to buy it, It's on Ausrotary page on FB ? Quote Link to comment Share on other sites More sharing options...

Just wow. 90k for an rx2.There has been a few RX3s change hands for north of 100k recently, so it's possible. Granted they were 9-second Pac-build cars like this:https://www.carsales.com.au/private/details/Mazda-RX-3-1974/SSE-AD-4726531/?Cr=2(Pac stickers add $$$ )How about a stock RX2 sedan with bare metal respray for $110k......can't figure out how to post a link but if you want to buy it, It's on Ausrotary page on FB ?sedan...tell him he's dreamin Edited 29June, 2017 by JV911 Quote Link to comment Share on other sites More sharing options...

DJM Posted 30June, 2017 Report Share Posted 30June, 2017 (edited) @jv911 what seals etc are you running in your engine. Mines about to be rebuilt, went to the engine builder this week and got the detailed story on rotaries, inspected my engine in bits, discussed steel vs (Ianetti) ceramic apex seals, factory vs solid side seals, porting options etc. wow very simple and tiny engines but you really want to know what you're doing assembling them for longevity. My guy says rotary are the most reliable race engines in the world. Unfortunately if you don't understand the detail, they fail easily leading to a bad reputation.I contemplated ditching my 13B BP Turbo and going 20B PP NA. Similar horsepower but it's probably $8-10k to rebuild mine to race spec vs $35k+ to source and build a 20B. Maybe next time.....my bridgeports are small and not well shaped so tidying those up will release a few more ponies. Probably going for steel apex seals - not as durable but they fail gently rather than Ianettis which take lots of abuse but cost $4k a set and shatter when they fail, goodbye engine.fascinating stuff. Would love to stuff a 20B PP in a 911 to turn up to cars and coffee ? Edited 30June, 2017 by DJM firstone 1 Quote Link to comment Share on other sites More sharing options...
Coastr Posted 1July, 2017 Report Share Posted 1July, 2017 Imagine the guy who first bridgeported a rotary. Starting it up, and then taking it for a drive. That would have been awesome. Sheeeeeeeeeett! Quote Link to comment Share on other sites More sharing options...

The last fresh one I saw was a race engine on Facebook recently for $35k....so $16k is cheap but it's a bit of a lucky dip, very sensitive to build tolerances etc so you'd want to know what you were buying.

firstone Posted 1July, 2017 Report Share Posted 1July, 2017 Love the NA timing overlap in any car but the Rotory is a feeling like nothing else.Peripheral port was the original design which they changed to the side port to overcome timing overlap ( amongst other issue's ). Side ports were positioned and reduced to overcome the same issue, so probably not a surprise to the first modifier. Quote Link to comment Share on other sites More sharing options...
JV911 Posted 3July, 2017 Author Report Share Posted 3July, 2017 Would love to stuff a 20B PP in a 911 to turn up to cars and coffee ?Sacrilege! (26B and you might be forgiven )My engine guy keeps his cards very close to his chest, so I can't tell you a whole lot about the spec, but I believe they are steel. Don't know what brand (guessing Pac) but even the stock Mazda ones are good enough for most applications. Quote Link to comment Share on other sites More sharing options...
DJM Posted 3July, 2017 Report Share Posted 3July, 2017 My engine guy says some seals work fine in big hp turbo drag cars because it's a short sharp sub 10 second blast. But for circuit racing, full throttle down 2 long straights at Sandown it puts a LOT more load on components particularly apex seals. And a lot of sustained hear. I had a low fuel pressure moment due to the stupid way my fuel pickup works and that led to lean out and failed apex seal. No catastrophic failure or noise but down to 10% compression when tested.

JV911 Posted 7August, 2017 Author Report Share Posted 7August, 2017 We have lift off! And all the front steering, control arms, crossmembers etc have been dropped off for sandblasting and powder coating, and new bushes, ball joints and the rods P-Kay, Pork Chops and DJM 3 Quote Link to comment Share on other sites More sharing options...

JV911 Posted 25September, 2017 Author Report Share Posted 25September, 2017 Well after being told “next week” by painter A for months on end, I lost patience organised to go elsewhere. Received a call from painter B saying he was ready on Saturday, while I was out shopping with the Mrs. Legged it home and organised a tow. It’ll be blasted sometime in the next fortnight or so and the extent of the bodywork required can be assessed.Also received the aforementioned steering components and cross-member all freshly coated and bushed. Will post some pics tonight. itsujack, WOKA and DJM 3 Quote Link to comment Share on other sites More sharing options...
deano Posted 5October, 2017 Report Share Posted 5October, 2017 nice rotisserie, much easier than lying on your back scraping deadener of getting covered in the stuff.I had a silver MX-5, great color choice.I look forward seeing pics of the car back.So will we see you on Current Affair in a cloud of smoke before Christmas?

JV911 Posted 5December, 2017 Author Report Share Posted 5December, 2017 The old girl is back from blasting (plastic bead to be precise) and I’m happy to say there were no nasty surprises. Sure a few areas are shagged, but we knew that already. The panel beater said, “it’s better than the majority of Rx-2s” he’s seen. Certainly better that some of the rusting hulks he has in there. Next step epoxy primer, then onto the metal work. Raven, P-Kay and Dalai 3 Quote Link to comment Share on other sites More sharing options...

JV911 Posted 5December, 2017 Author Report Share Posted 5December, 2017 I dare say so. You could in theory try and drill out every hole then MIG them up, but I think it's beyond that. Looks like previous dodgy accident repair - trying to repair a repair doesn't usually end well. As an aside, any pics of the HQ?
