I have a ST185 I bought a year ago. I bought the car without an engine and I swapped in a Gen 4 3SGTE with CP Pistons, Manley Rods, Cometic Head Gasket, ARP Head Studs and Main bolts, Gates timing belt, AEM 320lph fuel pump, CT20B turbo, 3" exhaust, and a Vibrant muffler. Stock head and stock injectors for now.
