Best compact 4 Zylinder engine?

[Bling]

4g63 beacuse i have one, and the motor has some serious balls, also the engine management is easy to tune on
which is NOT the case on say a ej20
sr20det is a great motor, stout block which ive seen/helped modify to make 450 rwhp
the old ford escort cosworth motor
or a 3s-gte...i mean top secret runs one in their top speed supra, so you know its go potential
