DIY Fuel injection thread.

Recommended Posts

Anyone got any experience with converting K-Jet to normal injectors? 

This is what the manifold looks like, you can see the six spaces for the injectors,
Ford-28-V6-Cologne-Inlet-manifold-Capri.

and with injectors installed

There seems to be some kits for other brands, like Porsche, but i can't really find any detail on how the injectors fit into the manifold. Im also pondering how to get fuel to the injectors with all their angles being on the piss, as obviously a normal rail wont work, so old school hose tail injectors running to a "remote" rail?

The injectors are also fecking long, with the narrow end pointing down into the inlet manifold (and you can just see the tops protruding in the above photo)
FORD-CAPRI-SIERRA-XR4i-XR4x4-Set-of-Inje

Other suggestions are to replace the manifold with a later model one that has normal L-jet injection, but there wasn't one for the 2.8 Cologne V6 and as far as i can see the 2.9 (which had L-Jet) doesnt fit?

Normally have the injector seats machined out to suit modern injectors.

@00quattro00   might be able to advise further.

The vag/porsche/mercedes had removable injector seats that you could replace with ones to fit an efi injector

 

You will require a funky ruel rail, might have to feed each injector off a hose

My photo of the injectors seem to indicate that they may also use a removable seat, albeit not screw in. Cant find much info on that, but still looking. Maybe i can turn the ID on them down to fit standard injectors, and retain them with the factory style clamp, and use hoses off the injectors to a remote rail.

Currently irrelevant, I just need to know if the conversion can be done. Be a good use of my spare Speeduino if it can.

Thats pretty much the only option unless you make a new manifold

So I made the 24-1 distributor trigger, it works fine. I just cut all 29 teeth off the wheel using my barry lathe and then used a mill at uni to drill 23 holes and welded in 2.4 mm diameter tig rod as teeth. Instead of welding it onto the shaft I made the shaft slightly larger with some weld, turned it down so that it was a little bigger than the wheel and then blasted the wheel with heat and placed it over the shaft. Perfect interference shrink fit.

 

I was having issues with the car cranking slow some times, not cranking at all other times, cranking moderately fast some times and starter motor smoking, and ignition interference while cranking. I pulled out the new starter motor and put in my original starter that I rebuilt the solenoid on and it cranks twice as fast, with no interference and uses half the power and doesn't smoke. Car starts nicely now - just need to play with the cranking advance and cranking fuel values to get them right again.

 

Hopefully they will take the new starter back. It was interfering with my ignition from day one, and was what made me make the ecu controlled ignition system.

I've always wondered with the Plug n play ECUs: if you just cut the engine plugs off the loom, could you use them on any engine? Like, take a plugin S15 Link, and use it to run a 4AGE? 

 

Other than the connectors, are they actually different?

But also, crank triggers are absolutely disgusting on this type of engine.

You know it's a K series, right? It's already as disgusting as it can get

no reason why you couldn't.  can all be reconfigured in software

I guess it'll depend on their trigger (cam crank etc) inputs and if you can change stuff. If its a link I guess you can change stuff

Yeah it depends, sometimes if it something like a powerfc then it'll have specific things to work with specific OEM parts.
For example you can use a 1ZZFE ECU on a redtop beams 3SGE engine, but you need to use the 1ZZ coilpacks or it doesnt work. As the return signal from the coilpacks is different. 
No such problem on a Link or Haltech etc, but again, sometimes they have bespoke options like the BEAN protocol thing to make the fuel gauge etc work in the Altezza plug and play. 
(A feature that the wire in ECUs dont have, so people actually bodge these into other Toyotas that would otherwise benefit from a wire in)

TL;DR: It's a lot of work for not much benefit unless its a special case.

Cheers, I'm not seriously looking just yet, but I occasionally see plug and play ECUs advertised for quite a bit less than equivalent wire in options.

I feel like a plug in would have less io connections than a wire in?

the nissan plug in links  ive done,  s15 etc.  have had plenty of spare io's on them on the factory loom.  plus you can buy and expansion loom/plug for them

was talking link specific in my previous post btw
