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.

Here some pics of the rotor housings before I had them resurfaced.

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.

Won't be the first semi p I built
Have done a few lately

Here's pics of them

13bre for a rx2
