I don't believe they make POR15 in aerosol cans, however it's just as easy to throw it in a HVLP paint gun and spray it on, you may just have to thin it a bit.

The clearance issue was mainly due to the large plenum size. As stated earlier in the thread, this was Mazworx prototype manifold when they first started producing the VVL swap kits and their first "street" swap was in an S13 hatch. Obviously the S13 doesn't have a large fusebox like the S14's so it wasn't an issue for that car. Since then, they have changed the plenum size to a smaller one and it now clears the factory fusebox in the S14 bay. The runners are a billet piece and are identical among this manifold and their new design. I wasn't about to purchase a new manifold because the fusebox was in the way, so relocating was performed and it cleaned the engine bay up at the same time.
As stated by the555car, runner lengths play a large role, among other things, in manifold design. Obviously, FI cars aren't as touchy as NA cars are with manifold design, but it still has an effect. I too am unaware of the key RPM band this manifold is aimed at, but I suppose I can call Mazworx and ask or I'll find out soon enough. If I had one gripe about the manifold, it would be that the runners aren't long enough. I'd rather sacrafice some high-end power for more low-end grunt, but we aren't dealing with a large liter motor or a V8, so I'll stick with what I have.
