Floorless240z Posted August 19, 2005 Share Posted August 19, 2005 I am quite curious, as I have never heard of it, and apparently there is a 3.1 rolling around w/an e33 head... +couple posts down I posted a question I have about converting a Z to fuel injection Quote Link to comment Share on other sites More sharing options...
johnc Posted August 19, 2005 Share Posted August 19, 2005 The E33 is supposedly a "special" homologation head that Nissan built to get the larger valves into the basic E31 for FIA competition. I think its a myth: 1. I and no one I know of has seen one. 2. I and no one that I know of has seen any reference to it in the Nissan Motorsports books. 3. I and no one I know of has seen the homologation specs for the head. 4. This E33 rumor just surfaced again in the past couple months after being dormant for 6 years. 5. The early E88 head is exactly what this mythical E33 head is supposed to be. FYI... E33 is a Nissan paint color code (Ultra Yelow) and an intake manifold code.

JMortensen Posted August 19, 2005 Share Posted August 19, 2005 What's the casting number on the early FIA head? I just checked How to Modify and there is no casting number listed, but it does give some different valve sizes for the "early and late" FIA heads. If it is the early FIA head it should have cast iron cam towers, that would be a pretty big giveaway. Quote Link to comment Share on other sites More sharing options...

I don't have the book in front of me but I seem to recall all the 'FIA heads' were four banger heads.... Ya know e88 becomes e33 pretty easy with just a touch of dremel and a splash of acid for that non-machined look.... Quote Link to comment Share on other sites More sharing options...
JMortensen Posted August 19, 2005 Share Posted August 19, 2005 Crawford, you are correct. In looking at the book I see that these are 4 cylinder heads. Quote Link to comment Share on other sites More sharing options...

Floorless240z Posted August 20, 2005 Author Share Posted August 20, 2005 it is real, i saw one yesterday at the convention. only time he popped his hood all weekend i guess. specs? Quote Link to comment Share on other sites More sharing options...
Floorless240z Posted August 23, 2005 Author Share Posted August 23, 2005 this top secret motor was also fuel injected- had an maf, and said it had a computer (not sure if it was a stock ecu or some sort of piggyback or standalone). what kind of numbers could you get with an e31 head and L28 block fuel injected? I'm just looking to have something a little more streetable. due to the exhaust smell, the 6 240z's in my family only get driven once in a while. I want something I can drive somewhere and not smell like exhaust fumes, so it seems fuel injection is the way to go. Quote Link to comment Share on other sites More sharing options...
Sparks280zt Posted August 23, 2005 Share Posted August 23, 2005 fuel injected Zs can reek of exhaust just as easy as the carbed ones. Its not the fuel system, its the cars shape among other things. In Misc. Tech there is a thread "Fumes in my Car" read it http://forums.hybridz.org/showthread.php?t=100260 Quote Link to comment Share on other sites More sharing options...
Floorless240z Posted August 23, 2005 Author Share Posted August 23, 2005 read all the way through that thread and others linked in that thread seems there is no real solution. looks like it will jus tbe a sunday driver. damn. Quote Link to comment Share on other sites More sharing options...
Sparks280zt Posted August 23, 2005 Share Posted August 23, 2005 Well if u read it there were some members such as Clifton who has no exhaust fume problems. I have rode it quite a few s30s and yes there is such a thing as one without exhaust fume problems. Quote Link to comment Share on other sites More sharing options...
