So my recent purchase is a impreza turbo 2000.
It has a td05 20g (set at 1.4bar)
3 inch down pipe to 2.5 inch straight through
440cc injectors
Walbro fuel pump
New age top mount
Simtek ecu
Piper cross panel filter

What sort of power do you guys think I'm making? Will be booking into a rolling road on payday but would like a rough estimate. It feels fast lol

 

I'm not an expert but after my research you would be at around 300 - 340 bhp

 

Fackin hell, that much really?

 

would be surprised if your under 300 bhp, I want the same spec as you apart from a td05 -16g and was advised 320-330bhp.

obviously every engine is different and not sure how a 20g impacts on that but just with a remap on a td04 it's around 260bhp

 

a 20G has potential for around 400hp. Your injectors will be limiting your power! and maybe the engine strength!
