Very is the answer. Last time I raced I was weighed at 1085kg, with me around 90kg, making car just under the tonne. That was with fibreglass bonnet, guards and bumpers. Plastic windows, gutted door shells, etc.
Have pulled lots of wiring out, cut off lots of studs and brackets, drilled lots of holes in anything non-structural. Will be interesting how light I can get, especially in the front for better balance.
As Dan said it’s the four pot S14B20 motor so good weight saving over the M20.
