@ Leon, A small curve will be in the runners that will aim the plenum about 45 degrees upward away from the brake booster. It will be a smooth curve just as the LD28, but not as far. Air horns will go into the overall design, and will be removable. Lessons for these are coming from the small high reveing ITB/ICB Crotch Rocket bikes.
@ bigbreak_2000, It will have the runners with a balance tube for balance/vaccume purposes, as well as the unit will most likely ship with a -8 vacuume log to be mounted on firewall/where ever you want for everything vacuume. For a Air filter, the unit will have a removable plenum for racing purposes, at the front of the plenum, a round port will be part of the unit for the attatchment of intake tubeing for a filter.
@ NewZed, We are doing a small one car shop on the side, We run into alot of people that "Can't figure out" and "It's been sitting for awhile". My partner and I have messed with Z's for a few good years now, and can help with advice, or repairs/mods to local Z Car's. Were not claming to be, or trying to be a full on expert shop. That being said, we pretty much just work on 71-83 Z Car's. We both do it all on the car's, but I also do fabrication on a diffrent side. Only example of previous work I can offer are in Fuel rails, Not stated before due to the fact I am not here to promote, but if you wish to see. There posted on Zdriver Marketplace and F/B pages "280ZX Drivers" and "MZC"(Midsouth Z Club)
@ m1ghtymaxxXx, a Turbo version would be a one pice unit, with a single T/B, the ITB's would not play such a huge differance in an application to where the air is being force fed into the engine. But, I do plan on a unit shortly after/if this unit goes to prototype.
If I missed a question I'll try to reread all the replys and answer them shortly.
