There the wieght issue, might not be 50/50. After all the rotary problems(the list is endless) i sure could have settled with 52/50 weight dist. It would be a **** ton faster than a supra as well, considering the rx7 weighs over 600lbs less.
Oh well, thats why im doing what i am to my car. Eliminating the shittyness from it...

if your not breaking ****, your not racing 
in anycase, cost and performance and emmisions is pretty much the answer. if the car cost 50k starting, then perhaps some of these issues would have been taken care of but it was not. in reality, nearly all relibility mods can be done for about 1-2k and you can buy a new engine for 2-4k so its not really that much considering a new entry level import (ex: camery or altima) will cost you more then the car+relibiity mods+new engine+new turbos. i have been seeing FD's go for less then 8k and that is pretty cheap... especially when you consider 240's cost about 3-13k and 86's go for like 2-5k. hell i have seen civics (the old boxy type) go for 3-6k

Here are my guesses on each...
Fuel mileage.
There is no single turbo that spools as fast with the same peak power potential as the stock twins, even today. Yes, you can get something like the RX6 to spool nearly (but not as) fast if you open the exhaust, etc. I wish Mazda made the control system a little simpler or more reliable, but the sequential twin setup still offers an unbeatable combination of quick spool and capacity. And that's coming from someone who had an RX6 single and is now installing a bigger single.
The stock raditor is light and works just fine for most purposes.
It keeps the throttle response snappy, but I generally agree that it should have been larger. Sucking the intake air from the same duct was not a good design choice, either.
This doesn't make any sense. There is no such thing as ceramic *coated* seals, ceramic seals are very expensive, and they don't offer a lot of bang for the buck.
And that's from someone who just bought a set of ceramic seals for his rebuild since the other alternatives available in the marketplace when I had to choose (Mazda's new 2-piece, and the RA seals) were not yet proven enough for me to be comfortable with them.
I've never heard of the oil passages being a problem, and I suppose the upgrades would cost money.

Why Mazda even go with the complicated and failure prone TWIN Turbo set up?
When a Single turbo system would of been simpler/easier and less failure prone.
espcially when some single set ups spool as fast and able to get bigger power?

Why Madza didn't put in a better radiator, than the POS skinny radiator that they
put in?? Knowing the heat the Rotaries make??

Why mazda put in such a WIMPY stock intercooler???

Ask Ferrarri how they win so much, and they will tell you 'more test time than anyone else.' It's very possible that the RX-7 was somewhat lacking in the long-term testing department, I'll definitely agree to that. But I still feel that those issues were resolved in the later models, the ones that we didn't get because of various socio-economic factors that were beyond Mazda's control. I guess there is one thing that they did to shoot themselves in the foot: they did such a good job on the Miata that people weren't willing to spend the extra money on the RX-7. Miatas are pretty darn fun, I recommend driving one if you get a chance.

Well my only grip about the Fd was the design of it's rats nest. I know the Fd was the first production vehicle to have a sequential turbo system, but they could have taken a little more time to develope a less complicated set-up. You would think at some point Mazda would have stepped back to look at their design and say......."**** we can design something less complicated than this"! Hell Toyota got theirs working right the first time. Mazda was capable of doing the same.

Yea... why didn't they let some idiot in NY design the car that has no idea what goes on in the background of car design.

You must of forgot too. Ford owns a percentage of Mazda.

Yes Fumanchu, but if they possessed so much buying power and been such a powerful company, why would they sell even a fraction of their great business? Your point is invalid, whether the entire company was bought or a fraction (which BTW is something like 55% making it Ford) they still wouldnt give up any of their company if it was so powerful.
