13b oldschool four port semi p?

I have a rx3 that I'm doing up.have a pair of oldschool repu rotor housings that have semi p's done to them,debating if I should just streetport the irons or do them bridge port.any one have done a bridge with semi p port?

car is going to be driven in the streets occasionally.
Also going to be running efi,thinking 62mm ITB's Ida style?
What size injectors you guys recommend?
I have a full s5 n/a rotating assembly that is going to be sent to get balanced and debating side race clearancing..also going to do all the engine oil mods I can possibly do with the help from you guys,open to opinions and advice so shoot away..
Just trying to get the best n/a horsepower out of these semi p rotor housings I have laying around.


I will post some pics of the semi p work done as soon as my photobucket is up and working again..

IMO race clearancing is more important than balancing.

You have any details on the housing resurface process? They look fantastic!

Havnt done much since I have 4 engines I'm building for friends.
Will get on it soon

Got a new racing beat Ida manifold that I'm going to have my friend modify for the semi p

Also the rx3 is a 74 but previous owner put a 72 front end on it so I bought a SP front nose and need to get a hold of the matching grill and headlight bezels for it.

Slowly but surely it will get there.
