I have a d-series with a dsm t25 turbo, i'm using the stock hf mani with a adapter plate going on to the turbo. But i want a aftermarket mani but i don't know where i can get one that has the same bolt pattern as my turbo. its not the stander t25 flange, its something diffrent...

 

well, what flange is it? post a pic

 

if your turbo is internally gated you could use a greddy manifold like here:

or http://www.godspeednet.com/servlet/t...CRX-D15/Detail
although with this last option the wastegate placement is awful. I would only reccomend that one if your going to block it off and stick to the internal wastegate

if your looking for tubular you would have to go custom since most are made for a t3 flange

 

aonther option is edelbrock: http://www.jegs.com/i/Edelbrock/350/...0002/-1?CT=999

 

they make t25 to t3 adapters
