GR Yaris will be making 1000bhp, not bad from a 1.6 litre 3 cylinder engine.

A quick run down of what we are doing:

7 speed sequential gearbox with ATS Carbonetic carbon twin plate clutch
Forged engine using a brand new short motor
Whifbitz CNC ported cylinder head
Kelford valve springs and 267-B cams
Lamspeed turbo kit using a Garret G25-660 turbo
Syvecs stand alone ecu
Lamspeed fuel system with flex fuel
Wagner Tuning intercooler kit

The car already has a lot of mods done like Verkline tubular front and rear subframes with Verkline rose jointed arms, KW suspension, Advan GT wheels, Airtec engine oil cooler, etc.
