Im going to buy either rx7 fc, Fd.
I heard the biggest prob with the rx7 were the engine rebuilding.
Is the rebuilding cost same with fc and fd?
And if there is a way i would like to swap with any kind of engine.
what is the easiest engine to swap in to the both rx7s?
and does Rx7 take up lots of gas? I dun think it does but lots of people say it does.. ne wayz thank you in advance
