simpler, yes, but far less acurate, distributorless system is optimum

Hi, you have to reopen your ecu and be sure your ignition out is wired, and you'll need some IGBT 's to control wasted sparks , with your cops ( are you sure your 300 zx ignitor is useful ? )
read the ms extra manual , every thing is avalaible .
with a 36-1trigger wheel , you put 50 degres in the soft TS

you said :
No dice! We checked for spark and we have it. In Tuner Studio the only alert that I see is
"Not RPM Synced" Im guessing that means MS is not getting a Tach Signal from EDIS?
how did you checked spark, if you don't get tach signal ? Lazeum is right, test inversion of sensor, it could work . Are you sure the basics are right in TS ?
good luck with EDIS , i switched to wasted cops and IGBT 's , i could not get good sparks with EDIS 6 but it was my fault (may be) ?

Hopefully working on my stroker soon and trying to make some decisions. I was going to go for 89mm.
23 hours ago, turbogrill said:Besides head gasket being a little pricey and a sonic test is recommended , is there any other issues/risks/costs?
Obviously custom pistons are needed.
the cheaper is to build your own multi layer copper head gasket , what i did , removable and no leak if well done .
custom pistons ? after market pistons exist , some times need over boring the rod at the pin

89 mm with F54 would be rather safe , but not with P30 or other blocks
my P30 from l26 was in the water at 89 mm , sleeves to come
i did not sonic test my f54, i think for NA it's enough
-
my F54 is bored to 90 mm , stock rods but much work on them, no problem for a NA engine , megasquirt injection and timing
-
front cover without water pump
-
The timing cover was removed and changed for a custom made in billet alloy
I dont Know the power

Hi, Already done years ago : 6 holes above exhaust pipes, and one big tube feeding water in reverse flow with an australian electric water pump Davis Craig.
Absolutely no problem of over warming
there are two little purging hoses in the upper roof of the head , for avoiding eventually steam , returning to the expansion tank
excuse my bad english in my explanations
Regards
Didier
PS : Peter Macdonnel built an amazing system like this on the Green Hornet , but no reverse flow

The one and unique thing to Know is the total lenght from valve to Horn limit, looking for second harmonic at your rpm wanted, that's all,

That is interesting. Have any pictures of your pan?
Well, i'm working on my Z sometimes, not so much anyway, i'll try to make photos of my pan, steering rack, etc ...as soon as possible
-
I made my own oïl pan with a sheet of aluminium, with a Weaver bros dry sump pump system, and lowered the steering rack, and cross member,, so i am about 50 mm ( 2 ") lower . You have to realign the gear box bracket ( 25mm or 1")
Of course, you have to modify the steering geometry to avoid any " bump steering" on such a bad suspension and steering system
-
OK,Matt, I have read everything, and i have the solution : Go for injection .......
-
Not sold , and not relisted ...what's the future of this head ? who knows ?
-
I swapped the two antic fusible links with a modern fuse box Peugeot . 4 x 30 amps blade fuses in a little box. very smart and reliable

MAG58's DOHC L28 Build Log
in Nissan L6 Forum

well yes , stock guides , just to make lower axes in the block, and the stock cover is modified to make some space, electric water pump ( davis Craig ) , and tensioner on the right side, in place of the water inlet ( spring and lock without oil pressure ) no need for oil pump drive or distributor for i put dry sump pump system and megasquirt ignition and injection EFI with yamaha bike itb's
So simple and cheap , just a little of brain storming !
oh ! and a little joke for the head cover !! Lol !
