Tried posting this in the Single Turbo RX7 section...no replies. Maybe this forum will have better results.
I'm building a 85 GSL-SE from the ground up. Motor was shot so I picked up a NA S5, which is also in need of a rebuild. Hopefully not much else. Then along comes the chance for me to pick up a turbo really cheap, so I snag it up. I know the compression on a NA S5 is too high to turbo, so do you all think I should scrap the idea of adding a turbo and stick with the simpler (and cheaper) NA street-ported S5...or should I rebuild the S5 with lower compression rotors, street port and slap the turbo on. I'm not a racer and the car will be street-driven on a regular basis, but not every day.
