I have a fmic, air filter, 3" zaust with decat, fuel pump, dark blue hawk injectors, forged rods and pistons and a super awesome innovate scg-1 . That should be sorted to 400, although I am on a 5 speed so won't be hitting that. If it doesn't work I'll have to sell it and get something else on. Just needed to know about the fitment for the snail incase I ended up waiting for parts.
