been looking for custom zed Plenums, have seen some before but have not found any anytime recently. anyone got any pictures?
http://www.aus300zx.com/forum/showthread.php?t=308934 This might help! ;-) Thanks to this thread for reminding me for my own Z!
here is one somebody on here made up for me. Ill let the pics speak for themselves. Its for a vq 30, but i guess would work for a single turbo vg setup
If your really trying to get every last bit from them you can match port the heads to the lower plenum and the lower plenum to the upper plenum. Some also place a spacer between the plenums to reduce heat transfer but also to lengthen the runners another 5mm or what ever it is...questionable gains.
