+1. Exactly.

The matter of compression ratios and boost has been discussed in great detail on this forum. We have had all kinds of conversation on the difference between static vs. dynamic compression as well as the importance of tuning the engine/ECU combo. We'll know pretty soon what the limits of the Renesis are, for sure.

hopefully the limits of horse power involve 4 digits

And all to the left of the decimal!! Cool.

not a damn thing really. There are probably some slight ECU differences, but that's it other than the RHD/LHD thing (which supposedly affected the exhaust manifold). In terms of power, etc. I have said it on this forum for about a year now... there is no difference. JDM cars that Greddy, Blitz, Phoenix Power, etc. have dynoed on a chassis dyno have landed at about 180whp. JDM gasoline has the same octane levels as standard USDM gasoline... it's just calculated differently (do a search on octane... RON vs (RON + PON)/2 if I remember right). As far as emissions goes... remember that "Kyoto Protocol" thing that the US still refuses to sign? Well... where is Kyoto? So yes... Japan has strict emissions and strict inspections every 2 years.

Thank you for posting that before I had to. RG has posted on this in his usual detail MANY times. Run a search...

no it wasn't. It was first displayed during shows last year on Greddy's test car. That was soon followed by articles on the "joint" development project with RE Amemiya where they applied the Greddy kit to an auto8. Whether or not RE Amemiya decided to try to go with this for sale or not, I have not heard anything about... however concerns about the tranny (torque converter in particular) being able to handle the power were mentioned.

As far as an FI next gen RX-7 goes... the latest article I skimmed at the convenience store here said that the engine hasn't been decided. There is a fight between Ford and mazda... Ford wants FI (Turbo or Supercharger) and mazda wants larger displacement. The drawings looked interesting... the front was like a cross between the MS front and the RB front. The side is like a 2 door 8 and the rear is pretty 8-like except that it had a single exhaust coming out of the rear rotor crest. But these are just drawings... when we see spy shots of test mules is when I'd start to make bets on specifics...

Sounds like its time for a compromise. Mazda do what Ford wants larger displacement and a turbo!

That's a very strange thing to hear, that Mazda actually wants larger displacement. Perhaps they don't want another rat's nest 13B-REW nightmare. It's also strange that Ford wants a FI engine...makes me wonder what they have up their sleeves for Ford's own lineup.

I wasunder the impression that Re Amemiya hadtheir turbo Rx8 since 2003 b/c thats when that sectionof their web site was created.

Regardless I dontlike what Im hearing about the tranny and torque converter. If I hadto upgrade allof that **** ON TOP of buying a turbo kit and install - $$$$$$$$ !!!! - I guess itd probably be more cost effective to sell my automatic for a stick and then put a turbo kit onto that.

Thats reallynot the route I had in mind but timewill tell

Well, retooling cost for additional FI would be cheaper than increase displacement which might be the reason for Ford leaning towards FI, while Mazda doesn't even want the additional hassels of dealing with FI because of the additional insurance required, (better cooling etc) which are more likely to be skimped to cut costs.

Thanks,

I woulnd't go overboard with the cooling, just play it safe with a radiator. I was also going to mention the compression rating of the renesis but had to get off (which was why my post was cut short).
