HS30-H Posted June 15, 2009 Share Posted June 15, 2009 Probably best described as 'blueprinted' from the foundry stage onwards. Certainly some of the factory race block castings were made in small batches under controlled conditions to ensure consistency and accuracy, but they did not really have any major visible differences to the stock production blocks. However, they were supposed to be using stock production castings - so that would be expected. A lot of work was done at the machining stages ( oilways, boring, Wills ring grooves, stress relieving and surface prep etc etc ) but nothing particularly secret or special. Nissan Sports even published booklets on how to prep them. Link to comment Share on other sites More sharing options...

R30hybridz Posted November 12, 2009 Share Posted November 12, 2009 Anybody heard of a N49 Head? Link to comment Share on other sites More sharing options...
ozconnection Posted November 12, 2009 Share Posted November 12, 2009 No. Could be an N47 head, sometimes the 7 can look like a 9. Post a pic. Cheers. Link to comment Share on other sites More sharing options...

A quick search using "head" and "e80" turned up this thread:http://forums.hybridz.org/showthread.php?t=128095&highlight=e80+head Seems unlikely that an AU head made it over to So. Cal, so maybe your theory that the E88 is just defaced might be the deal. But it looks like there is such an animal as an E80 head. Link to comment Share on other sites More sharing options...
72zman Posted December 11, 2009 Share Posted December 11, 2009 i saw that earlier but it really didnt say much about it. ive googled it a ton and nothing has turned up. i guess when i get it ill take a look. thanks for the advice though. Link to comment Share on other sites More sharing options...
blue72 Posted December 12, 2009 Share Posted December 12, 2009 AFAIK there is no such thing as an E80. The only instances I have seen which refer to E80 cylinder heads are misidentified heads that later turned out to be an E30. Link to comment Share on other sites More sharing options...
19762802+2 Posted March 23, 2011 Share Posted March 23, 2011 (edited) Nevermind it wasn't a L6 head. Edited March 23, 2011 by 19762802+2 Link to comment Share on other sites More sharing options...
madkaw Posted June 30, 2014 Share Posted June 30, 2014 (edited) I recently aquired an E-88 head from a member.. As I have searched I have come across numerous threads discusiing the various E-88 heads. I guess there were 4 versions from what I have found. I am attaching pics of the two that I own now. The one on my engine now is from 9/71 . The one I just aquired,(dirty) is from a 72-not sure what month. The 72 seems to look exactly like the E-30 listed early in this thread. I wish there was a pic of an e-31 head in this thread. If I missed it I'm sorry, but thought it was(is) strange that the very first head is not pictured here. Anyway, not sure how you would describe the combustion chamber on this 72, but I laid the straight edge across the chamber to give some perspective. The 9/71 ( clean) head has been unshrouded and milled .012 Edited June 30, 2014 by madkaw Link to comment Share on other sites More sharing options...

Never know if I should shave it to make it flat or leave the dip there... Would be quite a lot of material to be removed if you wanted it flat. I haven't kept track of this thread and how many versions of the E88 there are but I'm pretty sure its normal. Link to comment Share on other sites More sharing options...
madkaw Posted July 2, 2014 Share Posted July 2, 2014 Looks like the 72 I just picked up. I was thinking more on the line of weld building the 'dip" to make it a high quench head. Link to comment Share on other sites More sharing options...
NewZed Posted September 21, 2014 Share Posted September 21, 2014 P90 Head Pictures: MN47 Head Pictures, and BTW the threaded hole is right above the heater jacket port, after number 6 cyl. Flow graph of different heads. DOHC Z Car head. All of these links are broken. Is this a dead Photobucket account or did some images get lost in the crash?
