Hello. I am just starting up my EFI build again after a several year break. Since I started the first time, I have become a manufacturing engineer and started my own small machine shop on the side to make up some income when my wife becomes a stay at home mom this summer. I have been lurking on this site ever since checking out other's builds.

I have a humble shop, but I do have a CNC mill with 30"x15"x6" travels, a Bridgeport, a 14x60 lathe, and a TIG welder.

I was thinking about offering up my services in exchange for either parts that I need for my build that you might have as a trade, or just offering to make more of whatever I make for myself for a little $$$.

Things I could easily provide right now are fuel rails, throttle body adapter plates, turbo flanges, injector bungs, etc. Whatever it is that you need fabricated for you build, I can provide. I am also a Certified SolidWorks Professional, so any design work you need done, I can tackle that as well.

I'll keep you posted as to what I'm making for myself and see if anyone else is interested in one while I'm at it.

Excellent! I think the two most difficult pieces (read desireable/marketable pieces) would be a fuel rail with options for a built in fuel pressure regulator and for a fuel return and a returnless fuel design. The other service that might be good would be the installation of injector bungs on intakes customers provide to you.

Fuel injection is the wave of the future for slant sixes. I have been slowly working on adapting a Ford MAF based system to the slant six. The last real hurdle I have is fitting the Ford distributor sensor from a Ford fuel injection distributor into a slant six distributor. I know the part will physically fit, but i need to design a mounting method and/or adapter.

Were you thinking something like the Ford rail mounted regulator that Aeromotive makes?

http://aeromotiveinc.com/products-page/ ... regulator/

Or something more like being able to hard mount interface with the rail via fittings?

I like the idea of the returnless fuel system, but we would need to do some research on how to best interface the fuel pump side of it. I think people have successfully used Ford's PWM electronic returnless system with MegaSquirt so that may be an option. There also may be a mechanical system that would work well for people who aren't all out 20+ psi boosting their motor. Although, I have a feeling it would be more cost effective to run another fuel line than to interface the returnless system to an EFI controller.

I barely have a grasp on what you were saying. The system I am designing will be based on the 87-93 MAf system used on Fords (usually Mustangs). It uses a pressurized fuel rail with a return to the tank. The type of fuel pressure regulator I intend to use will be a stock Ford variety to fit this particular system. I have no experience with Megasquirt, FASTEFI, or any of the other aftermarket systems.

My thoughts would be a fuel rail with a hole on each end that accepts standard thread fittings so the system could be designed to have a return or to be capped.

Well that's easy enough. I think I would use the 6an size fuel rail stock and tap the ends for either 9/16-18 for an o-ring to AN fitting or a standard npt thread, maybe 3/8 because of the .5" through hole in the fuel rail stock.

I would think folks wouldn't mind some tapped or through holes on the flats for mounting as well.

How much do you think you would charge to weld injector bungs onto an aluminum Slant manifold and make a fuel rail to match, with mounts to the manifold? I understand if you'd rather PM me an answer...

I also have an Aussiespeed short runner w/ cast-in inj bungs that can just be drilled. I assume that would be a different quote/price.

I have 2-3 manifolds I am looking to mod in this way, and might also want to chop the driver side end off a manifold and have a TB plate/enclosure welded on. So, there should be at least 2 and probably 3 jobs here.

Have you done projects like this before, and if so, pics of your work?

Thanks much,

Lou

Ok. This is what I'm thinking for pricing.

Fuel Rail, unfinished, brushed - $80

Fuel Rail, anodized - $100-120 depending on type and how many I can do in a batch

Fuel rails include sizing to your injector type and type of threads on the ends for fittings. Do you guys want more or less features on the fuel rail?

Modify Manifold for injectors, (built in bungs) - $80

Modify manifold for injectors, (weld in bungs) - $200

Custom throttle body plates/adapters - $100-150 depending on complexity. I will weld it onto a manifold for $100

I'm not sure what I want to do for brackets yet because everyone's height needs are going to be different depending on injectors.

Prices will be adjusted up or down to reflect actual cost once I've done a few.

I found the manifold, adapter plate, and fuel rail I made several years ago yesterday and will post up pictures tonight.

I was thinking that the fuel rails would be sold with threaded fittings on each end and pre-drilled for injectors. Personally, I will be using Ford injectors for 89 vintage Mustangs, so I would be interested in having the fuel rail pre-drilled and ready to accept Ford injectors.

As far as brackets go, if you could incorporate a bracket or brackets that used the two pre-existing bolt holes in the top of the head (commonly used for pulling the engine) but had a bracket that could be adjusted for different height injectors, I think it would sell well.

Just so you know, THIS website sells extruded fuel rail for $10 per foot, as well as injector porting tools and fittings and injector bungs for $4.50 per bung. A slant motor would need a fuel rail around 3 feet long, so figure $30 for the rail, $27 for the bungs, and $130 for the injector port drill bit (11mm or 14mm). Given those prices, I think a price of $350-$400 would be fair for a complete package of modifying a customer supplied intake to have bungs and providing a fuel rail drilled and tapped to the customer specified sizes and ready to bolt on.

A slanter who was handy with tools and economy minded could set up their own intake and get a fuel rail for around $200, with most of that cost being the special drill bit for the injectors in the fuel rail.

Reed,

Regarding the rail, I was thinking that I'm a cheap guy and I might want to source my own fittings if I thought I could find them cheaper. But I could also see putting a "kit" together with fuel rail pre-drilled for injectors or your size choice, fittings, universal mounting brackets, and hardware.

That is where I was most likely going to get my rail stock as I purchased from them when I made my first rail. I most likely would not purchase the special tooling as I have the ability to make any diameter hole with the use of an endmill. The injector holes would consist of the through hole, counterbore to match injector sizing, and radiused counterbore edge to facilitate o-ring insertion.

I guess $350-400 does seem about right for a welded bung intake with fuel rail once you add brackets, hardware, and fittings.

I just want to make sure that it's not priced out side the range of the average joe's EFI project. I'm willing to do as little or as much of the work as people budget allows the to piece it together.[/img]

Here is my first shot at uploading pictures:



I think if you click on the picture you'll go to Imageshack to the rest of them. There you can catch a glimpse of my equipment. The mill is a Tree Journeyman 425 that I retrofitted with a Delta Tau UMAC motion controller capable of full 3D contoured machining. The control panel and box is aluminum and I formed, welded, and machined in my shop. I put the electrical enclosure together from scratch.

That has been my most frustrating and rewarding project. The programming and hardware manual for the Delta Tau motion controller is literally thousands of pages long and I think I've had to read every single page during my troubleshooting phase.

There is also a picture showing the last set of parts I made for a customer. I shouldn't should have any trouble punching six little holes in a stick

Modified cast iron manifold bored to the dia of the TB, fuel rail- black anodized(only requires 21.5" of fuel rail stock), and TB adapter for a Buick 3.8. Made my own bungs and JB welded them in although I planned to remove them and braze them in as I don't think the JB weld would last long. I was right out of high school when I put this together, so I would not do it the same way now that I'm learned. I would be willing to let go of those parts as I have grander plans for my project now. I have the throttle body somewhere as well. Make me an offer!

I designed this setup to allow me to run my stock 1920 while working on the rest of the conversion. All I would have to do is swap out the carb for the throttle body when I was ready. I also made an adapter so I could use the stock throttle cable and kick down linkage with the TB. Unfortunately, I was never ready so I took it off the engine and swapped my other intake back on.

Casey

If you didn't have to purchase the special bit for the injectors into the fuel rail, then you could probably offer a complete setup (manifold and fuel rail) in the $200-$300 range. I think that is well within the budget of someone looking to start a fuel injection swap. Heck, when the time comes for me to actually get an intake and fuel rail made up, I might drop you a line! I would rather pay a bit more support a member of the slant six community.

I was digging around in my 'stash' looking at parts I wasn't really needing anymore, I do have a 36" long Holley fuel rail blank, a couple fo 24" rails, and 16 holley bungs to weld in or epoxy, and I think I have 12 injector bungs that are NPT threaded also that I may not be using anytime soon.

Nice to see a local be able to hang out a shingle and fill this special niche.

Hi Casey,

Thanks for posting estimated prices on these parts and operations. Sounds good in general. I have to take stock of my projects, and then I will likely send you an intake.

All the best,

Lou

Not a bad first attempt, but sadly, on that Web site a user has to be logged in to view your shots. I'm probably not the only one to think it's a lot of work to register and log in to a site just to take a peek... If you're looking for a better alternative, I've had good luck with PhotoBucket, though I'm sure there are others.
Like your attitude. Thanks for stepping in to offer. I'll be thinking of what I might need, since my brain always seems to run at high speed creating wishlists for machinery that's really too expensive to justify owning.

That's weird. I haven't had to sign up to see all the pictures when I click the posted picture. I will switch to another picture host if it is easier for you guys. I don't have a lot invested into the ImageShack account.
