mario_82_ZXT Posted May 14, 2008 Share Posted May 14, 2008 Personally, I would run this flange: http://cgi.ebay.com/ebaymotors/T3-T4-and-T3-turbo-header-manifold-adapter-to-T4-flange_W0QQcmdZViewItemQQcategoryZ33742QQihZ002QQitemZ120261496174QQrdZ1QQsspagenameZWDVW Mario Quote Link to comment Share on other sites More sharing options...
JSM Posted May 14, 2008 Author Share Posted May 14, 2008 I think were still stuck waiting for a donner header to copy still, right Jeff? Quote Link to comment Share on other sites More sharing options...
TrumpetRhapsody Posted May 14, 2008 Share Posted May 14, 2008 Not that it makes a differnce to the buy, but I'll be using a holset HY-35 with a T3 flange. It sounds like your R&D is in the ballpark for it's flow too, so I'll shuddup. Quote Link to comment Share on other sites More sharing options...

alexdeprat Posted May 14, 2008 Share Posted May 14, 2008 Hey guys, just to let you know, I already e-mailed Jeff (by PM) the pictures of the turbo header that I can gladly provided (with a return address) for you guys to use it as a template or as an idea to start the project. If you guys wish to see the pictures of the header, they are on my photo album, under my screen name:) Alex Quote Link to comment Share on other sites More sharing options...
jgkurz Posted May 14, 2008 Share Posted May 14, 2008 I'm also looking into a possible doaner. Stay tuned.... Quote Link to comment Share on other sites More sharing options...

sticky280zx Posted May 14, 2008 Share Posted May 14, 2008 sooo where are we on this as far as with the production company....? are they still needing specs....or are we just gonna send a header and them copy it? Quote Link to comment Share on other sites More sharing options...
jeffer949 Posted May 14, 2008 Share Posted May 14, 2008 Ok sorry for the delay. I will give you guys an update tonight im late for pool league other wise id do it now. till later Jeff Quote Link to comment Share on other sites More sharing options...
Guest daytonaz Posted May 16, 2008 Share Posted May 16, 2008 im interested in the manifold, and even possibly making a manifold, but it would help if we had a price range in mind and a few pictures to go off of. i work at a shop here in wisconsin and i have a 75 280z and i have an extra motor set up on a stand. so if anyone has a few pics to give me a rough idea i can go from there. my email is daytonaz_05@hotmail.com Quote Link to comment Share on other sites More sharing options...
sticky280zx Posted May 17, 2008 Share Posted May 17, 2008 http://forums.hybridz.org/attachment.php?attachmentid=6672 that is the one we want...in a t3 flange...and cheaply priced but good quality Quote Link to comment Share on other sites More sharing options...

jeffer949 Posted May 24, 2008 Share Posted May 24, 2008 Ok guys sorry for the long delay. Here is where we are at with the manifold. They have a stock cast manifold to make one off of. But they are saying they can only make a copy of that one and i have a feeling it would turn out like the bhj one. Here is the copy of the last e-mail i got from the guy. Jeff OK - we got the cast Manifold So - do you A) want to make " EXACT DIMENSION CONFIGURATIONS " based on what to do for the engineer and email them to me ? OR Have us make the manifold as it is, with stainless steel , and tell us where to add a gate flange and all that Just let us know what to do ........ EXACTLY ........ and we will start to do it Thanks! Honestly guys im a little lost on what we need to do from here. and could use some help. Do we just want to say make one or do we need to basically design one and send them the dimensions. So what are you guys thinking? Then we can go from there.

78280z Posted May 24, 2008 Share Posted May 24, 2008 Well, as far as I can tell, the original purpose of this group buy was to obtain a turbo header that flows better than the stock header and has an external wastegate flange. Now we are faced with the decision of designing just that, or replicating the stock manifold in stainless and adding an external wastegate flange. If we replicate the stock header in stainless, it may flow slightly better due to the differences in roughness in materials (basic fluid mechanics losses stuff), but it will still be almost identical with the exception of the addition of the external wastegate. As far as I'm concerned, I would not want to pay $200 for the addition of an external wastegate and close to stock flow characteristics when stock headers can be found for $50. We have the opportunity to design a turbo header, have it produced for us, and be able to buy it for around $200. We might as well give it our all and design the best performing header we can (that also best accommodates everyone's interests). Just my two cents...

col Posted May 24, 2008 Share Posted May 24, 2008 From what you said , if I got it right , you sent a standard manifold and they want to make an coppy of that. Didn't they originally ask for a manifold to coppy exactly? I think we need to find the best manifold that someone is willing to send to them ( they should send it back when finished). There was a manifold that most people seemed to agree on.(Someone posted pictures of it) . Was that just pictures, or does semeone have it to coppy? If not maby post a question to all members asking for help getting a good manifold, that can just be cpooied exactly. Quote Link to comment Share on other sites More sharing options...
