I am looking to buy a cheap header to well some 02 bungs into and do some per cylinder data logging on my evo 9, which still has the stock turbo. Alot of the cheapies on ebay have a connector between the cylinders with bungs already welded in. Since I want to log the cylinders individually I do not want this. I found the header linked below, that has isolated runners, but it says its only for the evo 8. I e-mailed the seller to ask if it would fit an 9, but got no reply. My guess is they have no idea what it will and will not fit. From what I can tell evo 8 and 9 manifolds are compatible. Is there any reason to think otherwise?

And before you flame me for trying to log a wideband in a pressurized manifold. I am using the AEM four channel wideband with pressure compensation. I am going to log the data use Evoscan coupled with the DLP-io8.

 

The manifold is the same.
