L28TMI The project of the year for me. I've just picked up a LD28 IP and 6 injectors. Along with my LD intake, im going to port match the head to intake, ****** up a turbo manifold and a stock T3 turbo. change out to the 76 N42 dished pistons i've been hording. Yes this is a Turbo Mechanical Injection project. With correct timing, by theory this should at least run. how well i have no idea. The very high pressures of the IP will create good atomization. Im not trying this for performance, just an idea i want to try. and Hilborn systems are way over buget for a "idea".

Specs:

F54 block-2.8 regular bore
N42 Dished pistons
E31,E88 or P90 head(still got to get one of these)
LD Intake-Injectors mounted halfway on runners, 80MM T/B
LD Injection Pump
LD injectors
Stock Ingnition
MSA's "high performance" oil pump upgrade

This project starts right away.

 

why???

 

because i can. really. i got an idea. i wish to pursue. With a few modifications, the LD IP will mount to the L28 just the same. Front covers will have to be mixed with each other. or a Ford EDIS trigger mount ignition used. LD28 block is taller, so will front cover, etc etc. Im aware that the LD28 is IDI, but still the pressure must be high. So what is the pressure the LD28 puts out at the injectors? Im aware the LD28 IP can handle a turbo, im only looking to push low boost, such as 5 to 7 psi. The timing would have to be advanced a bit to compensate for the extra travel time through intake. Im aware diesels are controlled threw IP, not a throttle body, So two cables would be needed. This will be a bit of a complicated build. but with a wide-band, and knowledgeable people interested in the build. could be successful.

 

Pick requests pics!

 

the pump will be here in a week. but it's paid for. Over at Nissan Diesel Forums(getting help on things like pump timing) they say the LD IP is lubed by the diesel fuel, and will be destroyed by gas alone. since she's now a project car, what can i put in the fuel, that is kinda cheap per tank of gas that can keep the pump lubed?

 

use leaded aircraft fuel for lube.. itll be just fine. i wanna see this one just as much as you fubar.. you have ideas i cant even dream of because im stuck in the same theory as everyone. at least i can see where your headed, something crazy custom. btw still havent installed the ms. waiting for more parts and time plus just got laid off again.

 

there's 2 diff types of normal leaded aircraft fuel 100LL which is blue and the most common of them all. 100 octane low lead, that's what the abbreviation is for. it also costs 4 bucks a gallon. And that's if you can even access airport grounds to get to a pump.

 

if leaded fuel would be best choice then older valve seats are a must for replacement. I think i can get me some no problem, there are 26 small craft (single and twin engine) air strips within 100 miles of me. no to mention 10 registered private strips( once less then a mile away) unless some one else throws an idea out, ima go with 100LL

 

The tetra-ethyl lead found in leaded avgas and its combustion products are potent neurotoxins that have been shown in scientific research to interfere with brain development in children. The United States Environmental Protection Agency (EPA) has noted that exposure to even very low levels of lead contamination has been conclusively linked to loss of IQ in children's brain function tests, thus providing a high degree of motivation to eliminate lead and its compounds from the environment.[13][14]
“ While lead concentrations in the air have declined, scientific studies have demonstrated that children's neurological development is harmed by much lower levels of lead exposure than previously understood. Low level lead exposure has been clearly linked to loss of IQ in performance testing. Even an average IQ loss of 1-2 points in children has a meaningful impact for the nation as a whole, as it would result in an increase in children classified as mentally challenged, as well as a proportional decrease in the number of children considered "gifted."[14] ”
On 16 November 2007, the environmental group Friends of the Earth formally petitioned the EPA, asking them to regulate leaded avgas. The EPA responded with a notice of petition for rulemaking.[9]
The notice of petition stated:
“ Friends of the Earth has filed a petition with EPA, requesting that EPA find pursuant to section 231 of the Clean Air Act that lead emissions from general aviation aircraft cause or contribute to air pollution that may reasonably be anticipated to endanger public health or welfare and that EPA propose emissions standards for lead from general aviation aircraft. Alternatively, Friends of the Earth requests that EPA commence a study and investigation of the health and environmental impacts of lead emissions from general aviation aircraft, if EPA believes that insufficient information exists to make such a finding. The petition submitted by Friends of the Earth explains their view that lead emissions from general aviation aircraft endanger the public health and welfare,


While this is an experiment, none the less. 100LL can only be used to get her running, i'll have to find a alt additive, or once running, and proven to work. a more self contained pump installed.

 

you can also run the fuel they use for vintage race cars. not as expensive and has lead type additives. i was talking to the 76 fuel guy this summer bout fuel and there are so many types its amazing. i was looking into c16 for my boosted road course car. you wont need different valves, they will do just fine, its the seats that determine that. the old seats needed lube, the new ones dont, but adding some wont hurt at all, the only thing i can think of is a bit more carbon build up

 

the 100LL will be much much easier to get.

 

I've been looking at fuel additives, Lucas has there injector cleaner and upper cylinder lube, a 10$ bottle treats 100 gals, i'll try contacting lucas to see if it'll work for the pump.

 

E85!!!! lol

and don't be such a puss on the AVgas. Though I really really doubt you'd be able to get it as easily as you think. All airports have methods to keep civilians off the movement areas.

 

Well with the private owned strips(allot of crop dusting around here) I can get a few gals

 

still nothing back from Lucas, although it is the holidays. I still have an issue on throttle. since the pump runs on a throttle cable. so. either a elaborate vaccume set up that increases the pump with RPM, or split the cable from the gas pedal. and maybe gear if if the pump needs a different increase of pull length.

 

I like the ingenuity, but can't fathom the reasoning...

Anyway, when you're done, throw me the IP, intake manifold and injectors. I could use the spares for my veggie powered turbo diesel 240Z project!

 

IWW the IP and Injectors only cost me 110 with shipping. Also the reasoning? just cause it's an idea. plus 1,950 PSI of fuel out the tips of the nozzles make for decent atomization. Old school look. Mechanical look. Just an idea, i wish to see work. Im bad about those things.

 

Well the pump is in. Unfortnatly it came in as I was headed out to work. Tomorrow I'll clean it up and take off all the useless diesel stuff. I'll also be changing to a N42 block. I have a low mile one in great condition. Plus my dish pistons are still installed in it. All it needs is my head and to be dropped in. After the first I'll be sending for the front cover. Alt mounts. And get her bolted up. I'll be using a stock T3 turbo for this. Nothing special. Still working out the fuel issue but Lucas is helping with that. It looks like 91 with there additive used Ina slightly larger quantity then the bottle recommends. Now its just down to modding the intake. Getting a head, and ignition issue. I need to use a Ford EDIS system for this.

 

you know, thinking about the fuel, you could ad some diesel to your tank, maybe a gallon every fill to get the lube part. some people have been known to do this to get an octane booster effect as well.

 

After looking at the pump much closer today. There are some features that really look good for this, Allot of crap can go, like the fuel shut off(the kill switch for a diesel) can go, the cable pulley can go, the throttle is already connected to a vacuum control. that solves the uglyness, and all linkages are already there. There are limitations, such as a max RPM of 5500, slower revs. handicaps really. but better pumps like Cummins IP's and Mercedes IP's can handle fast revs, and revs to 7K. But it's got to start and run with decent AFR's before i'll invest in those.

 

Sounds like you have a crazy, one of a kind customized, out of this world modification. Will be quite anxious, to see the end result. You are out there man. Good luck.
