Ok to give you an idea what you might need I had a 2TG in my TA22 . I used the 3T crank and pistons ( flycut ) had about 11.2 - 1 CR , 288 cams with .400" lift , extractors and 40mm sidedraughts . The best time I run was 14.8 , so you may need to go a bit bigger in the cams and run CR about 11.5 and get a set of 45mm carbs .
