Can anyone suggest a tank size for a 2.8 efi in my 240z,

thinking about 1.5lt, I'll have to have it custom made does being a rectangle shape make any difference?

Are you talking about a gasoline surge tank for heavy cornering? If so you probably don't need more than about 1/2 liter, just make it tall and skinny. Here's an example: http://forums.hybridz.org/showthread.php?t=94570

yeah I was wondering this too, what do you mean by the surge tank?

Here's a nice link to a surge tank DIY.

Thanks all, surge tank or sometimes called swirl pot, driving with less than 1/2 tank is causing problems on fast switchbacks in the zed, so Ithink I'll fit one under the washer bottle inspection lid. The exhaust tube sounds a good idea and place to find a builder.
