After much trolling through Google images, I have found a few options for electronic injectors that have an extended tip length to help "unshroud" the tip when installed in my CIS runners. VW Jetta 2000-2001 1.8L engines use a #30 version which is probably the best choice, but have yet to test fit one. This pic is an injector tip from a 2007-2008 Toyota Camry 3.5L v6, 420cc(?), 12 hole spray tip. With the injector seated in my modified holders (not much more to gain for depth when accounting for the injector ring seal on this injector body style), the tip is just past the "unshroud" part of the injector bore hole. The walls still below the tip might be hit by the spray - just not sure yet without testing. Hoping to find the VW parts for trial fit and testing if I can rig it up.
Another option is from 2005-2008 Toyota Tacoma 2.7L I4 - it appears to have the same external size as the Camry injector, but haven't found the flow rating yet.

Got the cam front housing drilled for the cam position sensor, then did the final assy of the seals on the nose of the RH cam. Pics are showing the cam sensor mounted, and the single tooth trigger wheel I designed. The odd shape opposite the single tooth end is the counterweight for rotation balance. The trigger wheel is installed outside of the cam gear, so easily adaptable, and the gear can be replaced easily with a stock part. The only mod I will do to the gear is drill a tiny, shallow hole to pin the trigger wheel to the gear once the wheel is timed correctly. I wonder if this "blade" spinning up to 3400RPM will make any noise!??

My TPS setup has been a small challenge with squeezing into the space available, and still orienting it for wiring access. I had to cut off the original hose nipples on the side the of the throttle body where the vacume pot for idle air used to be to make room for the new TPS. After that, it worked out quickly. The adapter plate has a short stub that fits into the upper hole, mainly to give more glue surface in a different plane than the end face of these bosses would allow. The plate will be epoxied onto the throttle body, with careful alignment to the butterfly shaft axis. After that, I still need to modify the shaft end to have a blade like a straight screwdriver that will engage the internal tangs on the TPS.
The LSx coils have a new home! After 3 trials of varying designs, this bracket works well. The fuel rail will clear past the coils nicely, and they have enough clearance underneath to not vibrate and hit the casting below. The stock GM ignition leads have the perfect length, and the wiring path to the coils and injectors will neatly tie to the new bracket. It also has 2 holes to mount the fuel rail hold-down brackets waiting to be designed after the rails are machined. Just a couple more brackets to design for fuel pressure regulator and rail mounts, then onto the wiring. This will be combined with tearing out the interior and dash so I can integrate the new harness with the old and remove any extra wiring from the old ignition and fuel control stuff. Once into that then I'll start updating my other thread again.

Nice work on that bracket. Very nice work.

Really is nice work, even cad plated it looks like.
I am impressed.

All I can say is WOW, can't wait for you to have it up and running!

That is a beautiful coil bracket!
It almost makes me want to go COP just for the cosmetics!

Thanks for the kudos guys. All the interest has me wondering if there is an opportunity here for a little business?

There is ALWAYS oportunity for a little business. If you can make one, make 10 at the same time and recoup some of the cost. That's what I did with the flywheel locking tool a few years ago. Made 10 and kept one. Very nice work by the way.

I'm interested in the brackets as well, if you can sell them at a good price together with a set of secondhand coils; they're very difficult to get in Europe... My MS setup with twin Ford coils work fine, but look ugly.

Thanks for the interest in the coil brackets! I can supply more, but first need to make copies of the design to work with the various LSx coils available. Ducman gave me a link which shows the variety of coils and I have the AC Delco D581. See http://msdignition.com/page.aspx?id=15358 . So, possibly 4 more designs to do, but probably created when needed by someone.

Just some small progress on the throttle body today. I say "small" because the little blade tang that engages the TPS was what I made. Also drilled the end of the butterfly shaft to mate with the stub on the blade tang. The OD of the tang is .002" under the butterfly shaft, so when it is clocked properly and affixed, the shaft can still be removed as normal. Got the throttle body test assembled, but still need to lube all the wear points before I can final assemble and say done.

how are you going to end up sealing the old vac port holes?

Variety pack of mini condoms from the local hardware store was my plan.

I just built a nice 16V motor for my car, factory new lower ends, Euro S top end. But I am thinking of pulling it out and putting in something more recent because I am not happy with with the CIS. So, yes, if there were a kit I could buy and install for less than the cost and effort of buying, transporting, refreshing and installing a 32V motor, I would be interested.
