I am the original owner of this joy of a car. Currently has 48,000 miles, it is just my summer fun car. The Biturbo ES has both the "E" package & the "S" package installed by the manufacture. It is one of two Biturbo’s imported into this country with both options. The car is loads of fun, if you can find someplace to let her go. Mechanically, she is sound. All the smog systems has been removed, I added the european “tuned” exhaust which should add 10-15 Hp. I have removed the air filter and installed K&N filters at each turbo. New MSD ignition & wires. I don’t know what all this has added, but this spring I will dyno it & then we will know. I know it is fast, quick, and maybe the dyno tuning will make it scary.
