Tim Walz Posted November 18, 2003 Share #1 Posted November 18, 2003 Hey all! Been out of the hobby for a while, since my son was born. I feel like a bonehead for asking the most common knowledge question, but which casting is the 260z intake manifold? I have a few intake/carb combinations from different cars, but I forgot which is which. Thanks, and try not to be cruel! Link to comment Share on other sites More sharing options...

ZmeFly Posted November 18, 2003 Share #3 Posted November 18, 2003 That is the casting number and they are said to give you a little more. Though you wouldnt want to use the boat anchors that came with the 260Z unless your doing a full on resto.Stick with the earlier carbs. Link to comment Share on other sites More sharing options...
Tim Walz Posted November 21, 2003 Author Share #4 Posted November 21, 2003 well, the only numbers I seem to have stamped on mine are e46 and e88, so i guess I don't have the 260 ones I thought I did. oh well... As for the nasty carbs, I would think it should be acceptable to use the 3 screw carbs in even the best full on restoration, since even Nissan dealers were putting them onto the cars as a solution..... but then again, I have never done a restoration, so how would I know what the "rules" are!

Bambikiller240 Posted November 21, 2003 Share #5 Posted November 21, 2003 E88 would be the casting number on a cylinder head. The casting numbers on the 240/260Z intakes are either E46 or N36 (one or the other) Link to comment Share on other sites More sharing options...
Royce Posted November 21, 2003 Share #6 Posted November 21, 2003 I've got a complete set and I am pretty sure the original US configurations went like this:E46 '69 - ' 71 240Z with 4 screw SU style carbsE88 '72 240Z with 3 screw SU style carbsE33 '73 240Z with Flattop Hitachi carbsE36 '74 260Z with Flattop Hitachi carbsThe E46 and E88 look very similar with the difference being the E88 routes water through the bottom of the carbs.The E33 and E36 look very similar, not sure what the difference is.Sorry to not have specifics. One day when I have a bunch of "extra time" I plan to take some pictures and document the differences.Hope it helps! Have fun! Link to comment Share on other sites More sharing options...
Bambikiller240 Posted November 21, 2003 Share #7 Posted November 21, 2003 Hi Royce:My 1972 240Z (mfg 11/71) came from Nissan with an E46 intake which does have provision to route pre-heat water through the carbs. I've never seen an E88 Intake or an E33 ,though I remember a balance tube assembly having a "something"33 casting number mounted on an N36 Intake.

Royce Posted November 21, 2003 Share #8 Posted November 21, 2003 Are you sure about that Carl??? While my E46 does have water running through the manifold it certainly doesn't have water running to the carbs. Are you sure you don't have an E88? You can certainly use the later insulators and carbs, that do have the water passages on a early manifold.I hate to disagree with you but I have seen quite a few E46 and E88 (and E33) manifolds to support my claim.I suppose another theory is that Nissan had some transitional pieces. It wouldn't be the first time. Anyone else out there have a E46 intake manifold that has provisions to run wather to the carbs, not just through the manifold???

Bambikiller240 Posted November 21, 2003 Share #9 Posted November 21, 2003 Hi Royce: I'm 99% sure that what I have on the car is an E46 and I'm 100% sure that it has carb water provision. Though I have defeated that provision with some hidden plugs in the water hoses. I don't have the car with me, so I'll check to confirm the casting number on my way home. PS I KNOW that you have torn apart far more Z's than I have. Link to comment Share on other sites More sharing options...
Bambikiller240 Posted November 22, 2003 Share #10 Posted November 22, 2003 Royce: OK, here's the inventory that I have. 2 - E-88 Intakes with Water to Carbs. 1 - E46 Intake without Water to Carbs.My mistake :stupid: Carl Link to comment Share on other sites More sharing options...
Royce Posted November 22, 2003 Share #11 Posted November 22, 2003 That's quite okay Carl! I respect you and was starting to doubt myself! Thanks for checking it out and following up! As you said, I've have taken a few of these cars apart. The problem is I haven't put that many back together! Take care! Link to comment Share on other sites More sharing options...
Bambikiller240 Posted November 22, 2003 Share #12 Posted November 22, 2003 Originally posted by Royce That's quite okay Carl! I respect you .............. And I respect you and your knowledge about these cars as well. Don't really know how I forgot about the E88 Intake casting. Sending you a PM on another subject.
