L series efi

[dimedude]

looking for a L series efi manifold L18e or homemade just seeing if someone has one and would be willing to part with:)

[bonvo]

good luck man you will need it your probibly better off making one from a z car mani

[dimedude]

i actually found one about two weeks ago on ebay australia the seller said he would ship it to the states but i havnt heard any thing from him for a week now so i think it might have fell through and i was thinking about cutting down the z manifold but i dont have a tig welder

[bonvo]

do you have a local fab shop? take it down there bolted to a head and tell them you need it welded together shouldnt be to terribly expencive

[Skib]

let me present a neat suggestion :D

 

:cool: this is going to be my next intake project......

an EFI mani is cut right after the injector mounting bolt hole and welded to duel SU mani and then fitted with twin throttle bodies

 

TonyD did one where there was just 2 large injectors per TB and it was all mounted inside hollowed out SU's.

totally looks like its running normal SU's but its really EFI. wish I could find a pic of it.

Contact Europe. The Jan.'79 through Sept '83 Sylvia (S-110) used an L18E engine.

About halfway down is the EFI SU setup

Reviving a old thread. I don't get a chance to be on this site much, but will this manifold do the trick?

I made these manifolds 15 years ago, and still have the patterns. Due to an absolute lack of interest, I have

Byron,

I was looking at your "Bronze" project on the Realm and wondered where your manifold came from. Thanks for the answer, I'm sure in my search I overlooked your stating it.

 

The issue I have is the intake track length and installation of air cleaners interfering with the stock brake master. I saw that you went from modified carbs for your throttle control to a short, dual butterfly, throttle bodies.

 

To me, including the butterflies made into your original manifold making it a complete ITB manifold would be a natural progression if these were to be re-cast. Also it could be an opportunity for the runners to be straighten going into the port and not have to curve to match the side draft base pattern.

 

Any future thoughts on reintroducing the L series manifold, this time as ITB?

I also thought about using an SSS dual SU manifold and mounting 2 Suzuki TL1000R throttle bodies onto it. The ITB's have 2 injectors each and 52mm butterflies. I felt it would work out to be about the right size for any L series street engine.

[Z-train]

Although it seems like a good idea,the Z manifold"cut-down" isn't.The ports(runners) are too big.One of the most important things in an L-20B is having good port velocity.

[yellowdatsun]

All depends on what your willing to spend, and what tools you have on hand. I have both a tig welder, an extra Z manifold sitting here at the house, and an extra L head to mock it up on.......soo I'd be all over just shortening one.

 

Last time I checked an L4 efi manifold was $200+

When I was considering going FI on my roadster I looked at these for a bit.

I would agree, Dave. This would be an ideal set up, but the cost for such low production numbers is really high per piece, and to honest, it's beyond the capability of my Bridgeport style manual milling machine which means farming out the machine work. For most guys wanting to keep an L series in a 510, it puts the cost of the project far beyond their wallets.

I made this L series EFI manifold originally in 1993, my first buyer wasn't until 1997, and I averaged 1 or 2 sales a year with this part until they were gone in 2007. I have two left - one on the Bronze, and one on the bench (in the photo above). My hand made individual runner throttle bodies were a pile of work on my little mill. I used new Webber throttle shafts and plates, and then just turned two rather larger chunks of aluminum into chips! I love em, but there just no way I could charge out my time on them. Trust me, if I were to even charge $50/hour the total cost would make TWM's complete IR EFI set up a bargain! This is the real reason why I haven

i scored a complete setup of thier 1st issue ITB's for the LZ22.

i may have the opportunity to upgrade to their current setup, before i try to install it :D

Man this extrudabody stuff is sexy!! Me want!!

I think I'm the only one who doesn't like the extruda lol. They seem so boxy/ridged and ugly, and still somehow still lack character. They don't match ANYTHING in a datsun engine bay esp a l series.

 

For the money I would go with jenvey. They even offer barrel type in dcoe format which is way superior to typical butterfly.

how about using the SU manifold and getting the SU style ITB's from TWM and running a stand alone ecu?

[Dime Dave]

Here they are 52mm ITB

Heh, agreed I think I just think ANY FI on a l-series 4 banger is pretty hot! But some of the manifolds made right here on Ratsun are way sexier!

The guy that is behind Extrudabody is a complete asshole. A couple years ago he was selling motorcycle ITB setups for L series four cylinders. I bought one from him. After a few days he says "my welder is injured. It will be a few weeks, or longer before I can ship it to you." After him completely freaking out on me, name calling and the whole lot I filed a paypal claim to get my money back. It took a while, but I got it. I, personally, won't ever deal with him again.

This is the thread for the SU manifolds converted to EFI, years back I used a 4cyl L series EFI manifold obtained from a Japanese engine exchange. Finding one of these manifolds would be an easy solution. I have seen a turbo L series use a narrowed 6 cyl N42 non EGR manifold, the motor ran great.

[dimedude]

so i got my efi manifold i had the guys at DGR fab cut down a 280z manifold it came out pretty good now i just have to start gathering all the other pieces

There are some interesting adaptors that allow 46mm SU to be used with GM TPI injectors.
