JustinOlson Posted April 6, 2006 Share Posted April 6, 2006 You can also get the fuel rail material from http://www.atpturbo.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=ATP-FUL-010&Category_Code=FUL Regards, Justin Quote Link to comment Share on other sites More sharing options...
Some-Guy Posted April 7, 2006 Share Posted April 7, 2006 looks great I cant wait till I can start making stuff like this fun fun fun! that fuel rail is cheaper to buy like than than make damn! Quote Link to comment Share on other sites More sharing options...
340ZXTTAZ Posted May 7, 2006 Share Posted May 7, 2006 OK 2802NR I would really like a set of those runner as well, and if you are going to be making the intake flange I would take that too. Crunch some numbers and get back to me. I could really use that stuff for my future projects. Thanks for the inspiration! Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted May 9, 2006 Share Posted May 9, 2006 2802NR: Your setup (airbox-wise) is exactly what I had proposed for a manifold design a year or so ago. I addressed what I consider an issue of rather uneven distribution of air to all cylinders. I can't remember whether it was here or on ZCar.com, and really isn't that important. Since I was thinking in terms of a turbo'd engine, I didn't get into tuning like you are. I am anxiously awaiting your results! Quote Link to comment Share on other sites More sharing options...
Hugh Posted May 9, 2006 Share Posted May 9, 2006 I'm always thinking in turbo terms... but in an NA application, do you need to taper the plenum towards the ends? Less air has to pass the ends of the plenum, and velocity needs to be kept up there, right? Or is that strictly for boosted engines? Quote Link to comment Share on other sites More sharing options...
Guest JAMIE T Posted May 11, 2006 Share Posted May 11, 2006 I think it's actually more important on a NA motor than with forced induction. It actually speeds-up and straightens the airflow to the valve. Basically you're turning the whole runner/port into a velocity stack. Good info on this guys! Way to go!

2802NR Posted July 29, 2012 Author Share Posted July 29, 2012 Holy cow it really has been 6 years since I started this project. Hard to believe it's taken this long to come back around but as I tore down my L yesterday to fix a dead head gasket, I finally had a chance to mock up this project that is nearing completion. I'm really happy with how things fit, it sits nice-n-low in the bay which gives me more room than I anticipated for some intake options, should I ever go forced induction. I plan on doing a little more clearance on the flange, then I have to come up with a jig for welding the injector bungs. After that I'll have it finish machined and hopefully I'll hear it breathing by the end of the summer. Quote Link to comment Share on other sites More sharing options...
roger280zx Posted July 29, 2012 Share Posted July 29, 2012 Lookin' good! Whats the plenum volume? What tb are you using? Quote Link to comment Share on other sites More sharing options...
2802NR Posted July 29, 2012 Author Share Posted July 29, 2012 The plenum I finally decided on measures roughly 3.5 liters, 125% displacement. Throttle body is a twin 48mm off of an LT1 corvette. I spent alot of time doing the math for all this stuff, I just hope my elevation (4600ft) doesn't hurt my design. Quote Link to comment Share on other sites More sharing options...
