My SR20VET...

[jr_ss]

So, some of you, well most of you may be aware that the DET manifolds bolt up. However, the ports are slightly lower in the head. Nissan raised the ports for cooling channels and to provide a straighter path to the combustion chamber, you know, that theory of a straight line between two objects is the fastest and shortest path… Unfortunately, that means some modifications have to be done to the DET manifold.

So, tonight, I was loading up my goodies for coating and I wanted to make sure what actually had to happen. I happen to have a spare head without valves here, so I bolted the manifold up and used my trusty little camera I mentioned in the last post. I am happy to say, I do NOT have to oblong the bolt holes in the exhaust manifold flange. If I gasket match the DET manifold, I can get away without oblonging the flange holes. This makes things a lot easier. I have ordered the correct gasket for the VE/VET, which happens to be a 6-7layer SS gasket as well. P/N - 14036-8H600. I will lay this on the manifold and bevel the runner inlets accordingly, so nothing is hanging down in the exhaust flow path as seen below. Don’t mind the semi blurry, partially focused pictures. I shake like MJ at times…

You can vaguely make out the black sharpie along the poet edges. I’d say this is 1.5mm to 2.5mm at most. The bottom of the port is not interfering with the flow path, only the top.
