My ideal would be 4 cylinders, 86mm stroke or shorter so it can get near 9000rpm, using the lightest/smallest block that can be bored out to around 1.6L, with switchable cam profiles e.g. VTEC so it can have an Atkinson cycle mode. Add a mild hybrid system, and if the car is a little heavier add a small amount of boost, no more than 0.4 bar for minimal lag.
The boost pressure has little to do with lag. Being a 1.6L you want all the boost pressure the engine can hold. Choose accordingly. GM's 2.0L Ecotec can be built to 1200 horsepower.
