is it just me or did i just read my head # as 13M? wonder if that exists...
casting was on the front...left of the exhaust side/port of the head....can't really see whether is 31M or 13M...

or could me i'm seeing the wrong thing....

it's at the place where ryco n12 mention....or alternatively, u can look it at the intake manifold side, also got the marking.

What does it mean if I have the numbers M2 and 11M on my block? I have a 15M head...not stock though.

11M is a standart block... i got the same for the e15t... 15M is the turbo head, but since all the block are the same (but some holes for turbo lines) i wount think it would differ

What does the M2 stand for? My block I'm building is stamped M2 and to the left of that say something, then says Japan.
Hey crazy-mart, where are your oil line/hole located on the block. I'm planing to drill and tap the holes now for future improvement

Also, where in Montreal are you located? I have family there and frequently go there.

im the south shore (st-hubert) to be exact

would be nice to see you around !! as for the taped oil lines... the return is on the front bottom right, about middle of cylinder 4 and 2 inch from the oil pan.. the oil pressure side is kinda special cuz its taped directly into the oil galery in the back of the engine... ill try to get pics to show it to you by next week...i would definitly sugest to use the oil pressure sending unit location if you plan on turboing the NA block.. in conjunction with a pressure limiter/vavle (would be about 10-15lbs max) or else youll destroy the seal in the turbo...

on my block... i got "nissan japan" "11M" "2M" and some 38262 or something too... like i said its probably the mold ## casted into the mold it self refering to the part ## ... Ie 11M is standart E-series part ##... 2m could be the mold used for 1.5/1.6 .. i would think the 1M could be the 1l/1.3l ... just a taugh

Yeah, that 11M head is mine. It came on that engine I got in the '83 B11. I highly suspect the block was a JDM E15. The head says 11M on the front in the standard place, and in the middle of the inside of the head, just under the camshaft, it also says 11M. This block had notched pistons to clear the valves, I kinda expected it to say 15M when I cleared the grease off the front casting number. heh.. Was 11M a special japanese casting? If it was, is there anything special about it that I might want? IE, is it better than a 33M? I have my freshly rebuilt 33M head on that engine for the time being.
Gotta love a good mystery.

check and see if you've got a Sentra "MPG" model... i don't remember how to check.... i have an '83 MPG, with a hemispherical head (no shrouding...) and shallow-dished, notched pistons... i believe this combo was good for a little more compression than a normal E15. NEVER put the plugs in that head hot. it'll crack like a mofo.

I am so confused. I have an E16 with an E15 head. I got an 11M block, but my pistons are only notched from previous valve damage and machining (so i thought), but when i look at the pistons, they say 33M on the side...what's goin on?

Crazy-Mart · Jun 6th, 2003, 12:24 AM

there you go, wath i think should be a guide line to part number in the E-serie...

17M - standart e 15
33M - later E16
11M -all E-series...
15M - turbo engine

when i ordered some stuff for my turbo engine i faced some 17M like the crank and piston, 15M head and turbo intake ... 11m block... misc parts are all numbers... or most of them... any input on this Blown, Myet ??

I know the 15m head has smaller chambers and bigger valves than the other heads .I would like to know what size the valves actually are and what size are the chambers in the other heads like the 33m.What are the largest valves that can safely be put in a 33m head and what are they out of?Also I was looking through an old motorsports catalog and noticed that the inner spring and the spring seat for the E-series has the same part numbers for the ones for an A-series.In the A-series section they listed a competition valve spring that had to be used with a special aluminum retainer.The part number for that spring is the same as the intake spring on a KA24,could this spring be used on the E-series?Why does that spring have to be used with the aluminum retainers?Does it have something to do with the installed height?Is the comp. spring used alone or does it use an inner spring also?It's recommended to use the KA24 intake retainers when putting dual springs on the E-series I wonder if you could go ahead and use the KA24 intake spring also.

Blown has a post somewhere about doing the K-series valve spring swap onto the E-series....do a search....you can use the KA innersprings but you have to have the E head machined down around the valve guide.
