Question for the experts,

The below turbo TD06SL2-20G (Photo) is a new offering from Kandodynamic on eBay, would this turbo be too laggy for a 2L engine, the wheel is a 20G.

I have also spoken to GT Pumps about their new twin scroll turbo that also has a 20G wheel, from there initial testing it comes on about 800rpm later than a VF36, but with great mid-range and top-end. They also offer the same turbo with a 18G wheel...

Too many options nowdays

Thoughts??
