Every Build Has a Story – Meet the Cars of SpeedSF
Forced Induction For Track Work: Supercharging Two Popular Platforms
The S2000 and E46 M3 have weight and nimbleness going for them. Do they need more power?
Richard’s MR2 Turbo: Not Too Pretty To Pirouette
Although Richard already had an E92 M3, he decided to spruce up his mid-ship sports car and spin his way into driving competence.
Lief Storer's GT-R: Big Dreams, Bigger Numbers
While Lief started out this ambitious build with a slightly different destination in mind, he ended up doing what so many GT-R tuners do: chase big numbers. In his case, however, he wasn’t after four-digit power figures; weight and lap times were the numbers he was preoccupied with.
Tailai's Supra: Keep it Simple, Keep it Sane
After blowing up an M3’s engine, Tailai Lihe realized power wasn’t everything. With this car, he kept the B58 stock, and instead prioritized seat time and cornering speeds.
Adam's S13 Coupe: Silvias Do More Than Slide
It’s fun to remember that you could pick up a turbocharged Silvia for a few grand once. Adam Swan took this car to the next level with a few track-oriented mods, but it’s still essentially stock; proving the Silvia can do more than go sideways.
Sam's Semi-OE Turbo Miata: Taking Advantage of Pre-COVID Pricing
After growing tired of his tuned Abarth, Sam scoped out a lighter, rawer, and more involving car. However, he’d grown accustomed to turbo power, so whatever he ended up buying couldn’t be anemic. Fortunately, his friend was looking to sell an NB with the whole Mazdaspeed powertrain already swapped.
Simon's STI Wagon: Many Mods Spoil The Subaru
The temperamental EJ257 has taught Simon quite a lot about to the lengths one should go when building a track car. As he’s learned through five engines and a lot of trial and error, the third-generation wagon’s best asset is not its motor.
Ed Susman's 718 Cayman: Proving the Four-Cylinder's Potential
After years of tuning flat-fours in Subarus, Ed Susman realized he might have a new audience if he learned to tune the new Porsche Cayman with that engine configuration. As he learned, it didn’t take much to make this 2.5-liter engine seriously powerful.
Showdown at Sonoma: Battle Between the Fastest Stateside A90 Supras
Jackie Ding and Will Kwok have both gone quite far in tuning their A90s—further than any others on American soil. With Gary Wong piloting Will’s machine, these two drivers demonstrate where variations in tuning are felt most around Sonoma Raceway.
