i heard that mazda released the rx7 with a twin turbo charged 20b in japan. i would like to put one in my 85 so if any one knows where i can get one please let me know.

I don't think that Mazda has ever put the 20B into the RX7. But try Rotaryinspired.

That sounds kind of high for a front clip. You don't need the trans, unless you want to keep it auto. I'd say shop around. I have seen them go for a lot less than $6500.;)
