plenum spacer+ stillen supercharger don't mix. But its cheap and sells used well so get it and just sell it later.

I suggest Motordyne engineering's 5/16ths spacer.

Stop with the shouting.

plumpzz suggested the Motordyne 5/16-inch spacer. Agree.

Does anyone have NISMO headers? Yes. Search the exhaust forum.

Will headers pass emissions in Virginia? I don't know. Ask in the regional forum.

The 5/16 MD spacer does go well with F/I "turbo & S.charged" and it claims up to 23 whp for F/I instead of max 15whp for N/A. If you have the extra cash I would go with there Iso 5/16. I went with a Blox 5/8 spacer and I bought the Iso lower gasket and CCV from a member here. I will post up later on the gains and cost savings if any. I also run a turbo so I am interested to see if I will melt the Blox as it uses a heat temper Polymer like the skunk2.

He was talking about the Stillen supercharger which is a roots style that sits on top of your engine, not a centrifugal supercharger (Vortech/Procharger) that sits in the OEM airbox location. I'm not sure if gains are to be made with a Stillen SC and spacer.
