ok I might be getting a 1987 Mazda RX7 1.3L Rotary Turbo. would this stock turbo be good for my 240? I don't know any of the specifics about it yet but I'll know tomorrow. if anyone has any comments let me know thanks.

u need a mainfold, and flang, and all the piping that goes with a turbo, new oil lines and cooling lines , but yes it should work, just make sure the turbo doesnt have to much shaft play.. b/c that turbo is really old..

is it a yellow rx7?

no it's that ugly gold/silver color it's half peeled off, but other than that the car's in good condition. and the turbo spools up really quick :)

whats the size... if its anything bigger than a t25, you should be just fine...
