You think maybe they tried moving the motor back to help with weight distribution? I have never had a chance to look underneath an FD, so I don't know what all that would end up affecting.

If my motor blows, I'd be interested in a subframe for the second gen. RX7. Seems interesting and very rarely done, and I think by then I would have the money to complete the conversion.

Then why did they need a scoop in the center of the hood to a flare over the front turbo? (I won't even go into adding the extra "nostril"...)

Sorry for no response in a while if anyone checks..for that matter......We are gonna start mocking everything up and making the subframe a tranny cross member and a new tubular PPF.. so it will be able to be sold as a full package. the prices are rough right now but figure around 2k. and that includes the engine cradle a tranny cross member and a tubular PPF for the rear. The rack will be kept in stock location and the control arms will be also. Pics will be available once it all starts coming together.

Obviously there are Mustang Cobras running the 8.8" IRS making well over 500 RWHP. Due to their suspension and subframe design, though (double bushings), it's not a good drag racing combination, designed more for comfort (what Ford was thinking of, I have no idea). The 300M chromemoly axles are rated for 800+ horsepower, according to the manufacturer, and have a 1 year warranty. I was told that my Zexel Torsen differential would handle a lot of power (700+) in a non-drag racing application, and I'm sure that an Eaton or Auburn unit would hold up just fine in those scenarios.
Put it all together with more rigid mounting of the differential, and the combination is probably good for 700 RWHP or more. Once you start drag racing, though, all bets are off. Drag racing puts incredible strain on drivetrain components. Anyone seriously considering building a drag-specific car should look into a Ford 9" solid rear end conversion.

yeah for the cost of that i would build a full rear for it..i have a 300m axles in the car with a kaaz unit but im not sure how well its gonna hold with the 2jz setup. I though about building a 8.8 rear with all mark williams parts. the 9" is nice but i dont need a rear that big. but who knows.
