Porting / irons/ housings - If you have input please post it

This motor will be street drivin once a week. And SCCA's more then likely. I am just trying to get more of my research together for this motor.

My plan thus far has ben. A 88 N/A block with S4 rotors and FD housings. I still have in the air to Bridge port it or J-Bridge port the irons. Race exhaust porting on the housings. Aluminum flywheel. Fully balanced motor with rotor clearance to be able to turn 10.5k. This motor will be seald dry sump with electric water pump. Motor will be turbo as well.

If I am going to do all this. What is your opinions/knowledge/exsperiance using MFR housings insted of FD housings? And what about just spending the money on aluminum irons? Do they ware very bad? Just not worth the money? Or are they great?

Or should I use FD rotors? Does someone have counter weights for them?
