Re: VW Jetronic mechanical fuel injection swap

I was trying to solve a big flat spot right off idle the other day. It runs great besides acting like a carb without an accelerator pump. I was able to drive it around my yard even but its not steet ready yet. The fuel pressure test results were close to perfect and I was starting to doubt the proje...

Re: VW Jetronic mechanical fuel injection swap

I got the fuel system sorted today. There are some threaded mounts on the trans that I was able to use to hold the pump and accumulator bracket. It's low enough to keep the pump happy and higher than the undercarriage so I call it a win. The thread pitch on them looks to be different than what I exp...

Re: VW Jetronic mechanical fuel injection swap

Thank you guys for your kind words. I stared this thing for what seems like days for a location to mount this big ass filter, pump, and accumulator. The filter fits by the intake and the rest has a home you will see in a couple days! I have some hose ferrules and a crimper the way so I can hopefully...

Re: VW Jetronic mechanical fuel injection swap

I made some changes to the airbox bracket for small allignment fixes and redesigned it as a single piece for easier reproduction. Made a flange for the cold start injector and brazed into the best location I could find. Aux air valve was going to be ported at the throttle body flange but after a tes...

Re: VW Jetronic mechanical fuel injection swap

As I go I’m taking notes and saving templates and artwork so yes. I can recreate most of this if it is successful. Some of the parts are a bit hard to find as they are from late 70’s cars but hard to find parts shouldn’t scare a Pinz owner! New injectors will be here soon and I’m hoping to get the f...

Re: VW Jetronic mechanical fuel injection swap

I was able to score a CNC plasma table a few weekends ago in trade, so yay! Not currently having income and ultra long shipping times is proving to make me think harder about how I go about this for sure! Stupid Covid. This week I made some progress on bracketry. I ordered some longer studs and made...

Re: VW Jetronic mechanical fuel injection swap

During the initial run test I discovered two very important issues. Too long of an assembly to waste space with a pretty TB adapter if it is to fit under the engine cover and even if it did fit, that rubber boot is hilariously too weak under full vac! So next idea.. build an ultra short one from ste...

Re: VW Jetronic mechanical fuel injection swap

So far so good.Early this week I bench tested the system, cleaned the injectors, made a mason jar fuel tank, mounted up the manifolds and attached the TB with a plastic printed adapter to the oem accordion boot. It's not pretty or permanent yet in any way. Today I recived the injector inserts in the...

Re: VW Jetronic mechanical fuel injection swap

OK,I had some time to move ahead. Casting was fun. I first tried investment casting and failed spectacularly! Next I went with the sodium silicate method with way better results. I'm new to casting and still learning a lot.Oh how I would love to have a mill. Most of the machining was done with a rou...

Re: VW Jetronic mechanical fuel injection swap

Got the patterns printed and tested the core with a mixture of sodium silicate and fine silica sand. This might just work out assuming things keep going as well as they have so far.

Full scale test print fits great. Now to modify the shapes for casting.

Re: VW Jetronic mechanical fuel injection swap

The Goatwerks system is superior to Jetronic in every way I have no doubt. I'm trying this route for a few reasons- My Pinz spends half the year living outside and can get a bit wet. This situation isn't good for electronics and has already killed off my diesel heater. Also the time period of techno...

Re: VW Jetronic mechanical fuel injection swap

I was unaware of the air volume requirement. Thank you for the tip and the photo of how they did it. I got further on the manifold castings and still plan on testing the system, however, I won't spent the time making brackets/fuel lines quite yet just in case it doesn't work well in this configurati...
