Fully Built SR20 S13 Dyno + First Drive! ( IT RIPS! )
It’s been a whole month since we promised the first drive of this SR20DET-powered S13… and today’s the day. After buttoning up the little things — gauges, exhaust, master cylinder clearance, and a brand-new wideband setup — we finally strapped this thing to the dyno.
First pulls? 360 HP → 409 HP → 443 HP at ~15 PSI. The fresh engine from @GARAGESZERO and Garrett 3076 turbo sound insane, and there’s plenty of room left — this setup should easily push 500+ HP when we turn it up.
But before we crank the boost, we had to get the car on the road. This is the first official drive of the MotionAuto S13 giveaway car, and it feels like a totally different animal compared to its old life.
