ok, so i got a turbo manifold on about 2 months ago (stainless steel which i now HATE) and ive had it on for less then two months and im only running 6psi... so im driving down the street and i hear a major exhaust leak and almost no boost. so i stop and look and see the #4 cylinders tube cracked, so i say what ever ill just go straight home and park and get a new one... well that didnt work because i got a mile down the road and all a sudden i hear this loud clunk and my exhaust sound like its straight header... well the wastegate blew completely off the manifold and hit the car behind me and the company i got the manifold from is not giving me another one or doing anything about it.. so i need to find a T4 turbo manifold for a b series engine and im having trouble doing this... id prefer cast iron now too so any one got any ideas? because i cant find just a T4 manifold, all i can find is t3/t4...
