ok, this is a dumb question, but I can't seem to find the right info anywhere... maybe i'm just internet retarded today...
anyway, on a 93 rx7, what are the stock turbo sizes? and what would one expect to pay for one in decent shape...
thanks

 

Twin Hitachi HT12 turbos w/51mm turbine & 57mm compressor

 

are they worth anything?
I mean are they set up so only fd rx7s can use them? or could they be used for another build?

 

It would be a royal pain in the ass to try and hook them up to anything else except maybe a second gen RX-7
As for price, rebuilt units run around a grand, you could probably find a decent used stock unit for about $250. If someone is selling one
most guys blow the stock unit and go with and upgrade to a single turbo.
