Toyota Starlet 16V 4AG
1981 Toyota Starlet Australia
Fully built 16V 4AG engine with the help of some skilled individuals. We used a rebuilt long block with TRD forged 12.5:1 pistons. Although we kept the bluetop bottom end, we added a ported head, Supertech valvetrain Kelford Cams 193-B after the initial dyno tune with the stock head. We put 20V Silvertop throttles on the drivers side and Niteparts headers on the passenger side, which lead to a 2.5" exhaust.
On the Mainline dyno, the engine produced 150hp at the hubs, which is not quite on par with @garage4age car (you should check him out), but it performs well on winding roads.
