Megasquirt Kits- Group buy/build??

[oldopelguy]

I haven't done all the pricing yet, but SDS does offer a weld-on injector boss for the newer style o-ring injectors that has pipe thread connections on the top so you can just use high pressure flexible tubing. They are a bit pricy, at $37 each, but if you take out the machining costs and the fuel rail material and add in the cheaper injector costs it seems like it would be pretty close.

I think with a stock plenum all you would have to do is cut a piece of flat steel or aluminum plate, buy the appropriate boss, and do some basic drilling and welding to be able to install "regular" injectors.

bob the jag xjs has the same injector as the 1.9 efi

as they rust like its going out of style there should be 12 at a time in a junk yard near you with low milage

[RallyBob]

Forgive me, if I am wrong, but I don't think a 1.9 injected motor was ever built. All discussion that I know of on this site is to fit a 2.2 injection manifold etc. onto a 1.9 motor.

Just to reiterate what Ron and Todd have already said, all the 1975 Opels imported into the USA (Manta, Ascona, and Sportwagon) came with the Bosch L-Jetronic fuel injection as standard equipment. This was also the only year for the 'Sprint' exhaust manifold in the US, as well as the larger front brakes (245 mm instead of 238 mm rotors, and appropriate calipers with larger pads).

I have a set of stock 2.4 o-ring injectors, 2.4 injector plates, and 2.4 fuel rail going onto a 1975 Opel EFI 1.9 intake manifold for my 1972 wagon EFI upgrade. Everything bolts right up! But those were the only 2.4 parts I had, so I needed another viable option for injector plates, hence the conversion of the 1.9 injector plates currently under way.

Bob

This is extremely good news since I have a complete 2.4 EFI setup sitting at home and have been wondering what I could do with it! Sounds like I'm all set!!

PS, did you get the Nissan throttle body yet Todd?

Yes I did Bob! I thought I had PM'd you but I guess I didn't...been busier than a one-armed wallpaper hanger lately. Thanks again for the throttle body since that is the last critical piece I needed!

Yup, the stock 2.4 injectors (gray ones) are rated at 192 cc's. Figure on about 153 hp (flywheel) maximum on a naturally aspirated engine before they run out of fuel. Forced induction engines run richer and need more fuel so, the hp limit would be a bit lower with a turbo or supercharger. But, easily upgradeable with aftermarket injectors...

Thanks for the input on the 1.9 EFI engines, I guess I have just never seen one, or if I have I didn't realize what it was.

Would anyone happen to know the real difference between the MS1 pcb2.2 and the pcb3.0? I know what MSII has the ability to control spark as well without the ignition add on, but I can't figure out the difference between the 2 MS1's.

I think MSI/pcb3.0 has the same pcb than MSII,
but uses the small 68HC908GP32 processor.
so MSI/pcb3.0 can be easily upgraded to MSII by adding the daughter card processor,
I think this upgrade was not built-in the pcb2.2 version.

I've looked into the options of all 3 versions and of course the MSII seems the nicest and most promising, especially for further expansion. Though if I do tune the ignition curve and I didn't go with a distributorless system (VR, hall, optical) Would I then need to rivit the distributor plates stationary? Would anyone ever want to control ignition through a stand alone ecu and mechanical and or vacuum advance? Should I even use the EFI distributor I bought or just use the early model with vacuum advance and then lock that one up when I actualy tune the ignition curve?

I would just take the distributor out of the equation, and go with a crank trigger and EDIS Ford-based system. Much simpler.

I have a cut-down distributor just for this purpose, it essentially consists of just the shaft to drive the oil pump and the distributor housing 'flange' to locate it on the timing cover hole. A small cap is welded over the center shaft to prevent oil leaks.

If, however, you decide to use the distributor as the trigger, then the advance curve must be locked out completely. Weld 'er up!

What would be your method of choice to mount the crank trigger?

I am having a custom steel crank pulley machined which will have a step in it to center the 36-1 trigger wheel. Then a few simple tack welds and it's done. It will cost about $160 for me to do it this way.

I could also just weld a trigger wheel to a stock crank pulley, but for racing I want the 'comfort' of a billet pulley for high rpm reliability.

[garrymc]

The Escort ring is about the right size for the Opel pulley. The outside of the pulley has a cleanup cut and the ring has a step machined in it to just barely grap the pulley. Everything was indicated in so it should run good when assembled.

It will need to be tack welded or bolted to hold it firm. The machine work was only to "jig" it together so it won't runout of round.

I have not mounted the VR pickup from the Escort yet. I think a bracket between the block and altenator bracket might work.

Could all of the edis compontents be taken out of a junkyard escort and used? Will the coil pack work?

Yes, you can re-use an Escort's EDIS crank trigger, EDIS module, and coilpack. Just a few mods to make the crank trigger fit the Opel pulley and make a pickup adapter for the timing cover.

[baz]

if the Ford cogged crank pulley is the same alloy one as we got on the CVH engined sierra(sold in states as the ford merkur) it is no good above 6800 RPM they tend to spread out around the engine bay at high RPM's

[jordan]

There are many companys that sell trigger wheels so the ford escort one would not have to be used, I was just thinking of using the escort set up becuase it is a small 4 cylinder, they are easy to find in junk yards, and they are cheap.

[Paul]

Oh my, that looks interesting.

Bob/Jordan/Gary, what year model rang Escorts have the stuff we would need?

Paul, this should answer your questions:
EDIS Ignition Control
It lists not only the 'how', but also part numbers for aftermarket parts sources, and the years that they were offered as OEM by Ford.

This company from the UK, Trigger wheels for engine management systems , has many aftermarket trigger wheels in various diameters and configurations. I will likely order a few of the wheels from them for my various projects. With the small diameter racing pulleys I often run, the availability of a smaller diameter trigger wheel is often a necessity. Tough to put a 5.25" 'ring' type trigger wheel on a 3.5" pulley!

Bob, do you happen to have any pictures of the VR sensor attached to a timing cover?
