L4 Fuel Injection

[Z chopper]

Late lastnight I ran across a forum where a guy modified an N42 Intake from and L6 to fit an L4. Like the dummy I am I forgot to favourite the forum thread, I have googled it for the past couple hours but can't find it again. I did save the pics though hopfully they can help me find the forum thread. I kinda want to read the thread when I am more awake, I do remember icehouse posting in it.

 

 

here is what he started with

 

 

 

and these pics were also in the thread

common way of making cheap L4 EFI intakes.

I have spent over 2 hours googling and searching and still can't find it

Nice welds .... :cool: ... . . . it's cool how there's casting marks where there should be welds .. . . . probably because it wasn't ever a 6cyl manifold.... :rolleyes:

[jon521]

id be interested in some more info on this, if you can find it haha

[RedBanner]

Will a stock l6 efi ecu run that properly, cant imagine it would, but dont know.

Hey, y'all forgot my thread! :D Let me go find it.

 

Here it is: http://community.ratsun.net/topic/22074-510-l20b-efi-conversion-the-project-is-finished/

 

The above looks like a factory L18 EFI manifold. Note, necking down a 280z intake works fine, but sucks for flow on top end. Intake runners are too small. I'm addressing that with the next gen manifold Joe built for me.

i like the way icehouse built his manifold

Most guys use a Datsun 4-cylinder ECU, such as the common 1980-1983 Datsun 200SX ECU. Icehouse used MegaSquirt of course cause he's a wizard.

that is what piqued my interest and went searching for info on L4 fuel injection and ran across the thread dat510 posted.

ya now that you draw my attention to it and me doing a bit more research (rereading http://ddgonzal.members.winisp.net/nwde/4586.htm ) while a bit more awake L18e manifold right

Factory injection manis like that were available in japan for Nissan 4 bangers going back to the late 60's.. we got stuck with carbs because it was cheaper... Japan actually cracked down on smog before cali really did, hence EFI.

dagnabit Merlin I should have asked you to keep an eye out while you were in Japan (if I had known)

[Dirttrack510]

I'm just curious, did these fuel injection systems have decent performance, when compared to a 32/36 Weber or dual side drafts? :unsure:

[DAT510]

since we're on the topic, Bolt on EFI?

[ggzilla]

You mean going back to 1972?

 

They used a license for Bosch Jetronic, so it was good stuff made by Hitachi. Far better than a Weber 32/36, better than twin Hitachi/SU, and similar to twin sidedrafts. Tuned-port runners, ITB, and port injection. Just like modern performance EFI. It wasn't sequential injection, but that makes almost no difference anyways.

 

It's what the 1975 Datsun 280Z fuel-injection models used.

[merlin]

meant to say late 70's... that mani troy is selling could be off an l18 or l20b from certain JDM cars 1977 on... have seen a prototype looking one on a l16 or l18 pic from 1970 or 71. there are lots of L series efi options ... hell a guy on Van Isle was casting his own manis i think... check the510realm.com

[Z chopper]

hmmm gonna check that out merlin maybe datzenmike or 510freak might know somthing
