Trooper/Big Horn: 4JG2 engine specs

[garyq]

boknoy: I think one has to see the basics of how a turbo works para maliwanagan dito. The turbine is moved by the exhaust gas coming from the engine. This in return is connected to a compressor wheel (more like a centrifugal pump) that "compresses" the air into the cylinder so that more air means more fuel you can inject producing more power. It takes a certain amount of exhaust gas to turn the turbine (because of inertia) kaya may turbo lag. The turbo syst has to overcome this so that the compressor on the other side of the shaft spins faster and compacts just enough air to the cylinder to give you the additional power. Pansin ko lang sa 4JG2 around 2000 rpm yung start ng noticeable boost and around 3200 rpm yung optimum. This is the reason kaya yun ang nasabi ko. Based lang yun sa rig ko. Hope this helps
