Hi everybody...My name is Fil and a have a B210 coupe that was imported from USA.I am restoring it at the moment.
I wonder what will be the best thing to do to my engine:
-raise compression and port the head wtih some new cam?
-turbo it?

Also have a new A15 head, high compression but with round ports...Can this head be ported to oval ports?It

I think even in the download section of this website there is a Datsun 1200 workshop manual in Portugese....I guess it does cover the A14 though.

Have you got a workshop manual - ebay is good for them here in Australia - don't know about Portugal though.
