Hi All,

I have the opportunity to buy a 1988 RX-7 with a 13B.  This is NOT the turbo.  Will I be able to
port and polish this engine to get 200+BHP or should  I be looking for a more recent engine.

Can

someone explain the differences for me.

Thanks for your help.

Yes you can port and polish it with the proper intake manifold it should generate
close to 200 HP particularly with a 2.85:1 gear box. Tracy claims he is working
on such a gear box.

Or you could Peripheral Port the rotor housings and easily get 200hp.  Right Jerry?
