84 GSL-SE motor rebuild, please help with a couple of questions.
 

I have an 84 GSL-SE and have an extra 13b motor I would like to get rebuilt with the most hp I can get out of it and still be driven everyday. I would also like to add a turbo kit to it eventually. What can be done to this motor to make good reliable hp? How much does this usually cost? Who makes a good turbo kit? Twin or single? Sorry, I am new to the RX-7 world. I am used to cams and heads and pistons. Thanks a lot.

I would go with a camden s/c running a conservative 5-7 lbs boost and a rebuild with stock internals and a streetport. Many will tell you different, but this will produce lots of torque and offer reliability. I'll be installing a camden this spring in my SE. Many would suggest lower comp rotors (more $$$), lighter flywheel (good idea if you can afford) but this seems sensible without getting exotic to me given the research I have done.

On my rebuild, I plan on using a 12a centerplate with either a small bridge or streetport next winter. Then with 3mm seals, I'll bump boost to the 9-11lb range.
