Interesting. I wonder why the "Supra 7" had problems with bump steer then. They must have done something differently.

 

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.

 

Mikey lets see some pics of this beast..

 

Is that a reagal in the back ground? I wonder if is a t type or a GN?

 

sorry i hadnt checked this for a while. When my car is done and everything is worked out i will be able ot tell you for sure what is good and what is bad about it. Some people havent tried stuff first hand but are still an expert but i will let you know for sure.

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.

That's right Greg. Care to make a smart *** comment about my checkbook for old time's sake?

 

What are you talking about??

 

i tried searching some old posts etc etc..i cant figure out what you are talking about. i am very curious to know...????

 

You're not the former owner of Philly Fab?

 

correct i am not...

 

My apologies, I thought you were a different Greg from PA.

 

nah.. its ok we all make mistakes

 

while you are here.....what kinda HP does that rear setup that you came up with hold? or an estimate of what it can stand up to?

To be honest, I don't know.

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.
