Definatly need some manifolds as mine are on the laggier side. I have a stalled auto, but they have gone 10.80 and my highest mph is a 127, all boost stock motor. On my 5spd I ran consistant low 12's, high 11's on race gas. Never had any issues with them. Mine setup will be forsale in about a month if your interested in some good condition used ones. Email me @ twinturboz161@hotmail.com if your interested, I can show you some vids of my car and how the turbos are.
