I have a 90 TII. I was wondering what all the turbod guys know about porting. I have a na and Ive done a street port it but I have no clue about turbo ports. The TII isnt going to be a daily driver so wild ports are OK.
THANKS

 

As big as you can get them with out having too much overlap, with out going in to water jacket, not cutting too much out of the corner seal ride and don't cut anything out of the outer oil control ring... worry more about the exaust port than the intake port...

 

would you think a big *** street port of a bridge. Or I could do a big street port and a bridge across the top?
just wondering

 

Street ports, are exactly that.... best for the street !

Some are fairly radical in design (to the max of housings both rotor and side) and will give you insane top end power (@8K+ rpm) while not suffering the low speed/low load excessive fuel consumption of a partial bridge.

Also keep in mind exhaust (system) back pressure, anything greater than a street port does suffer with anything over a legal or near legal noise limit, these are the facts of life unfortunatley

If the low speed economy and noise are not an issue, then go a full PP...... I know I would
