 |
|
I have a bad habit of buying new parts when I don’t need to and I decided to replace all four of my injectors with these standard motor FJ6 injectors. Amazon says they are compatible with my vehicle but that doesn’t mean they really are.
The main reason for buying new was because two of my existing injectors were either a different brand or something compatible and I wanted all matching injectors (despite the fact that all injectors came back from cleaning with similar specs).
Visibly they are shorter and don’t have a cap?
Sorry for the bad pictures, I didn’t want to take it out of the bag.

Here is a thread discussing them in depth: https://www.thesamba.com/vw/forum/viewtopic.php?p=8438230

Thanks for the offer. I actually found that thread a while ago and tried to get an update on it but no one replied. Since my knowledge of this stuff isn’t that great, I really didn’t take much away from the thread as to whether or not the FJ6 injector are good or not.
I’ll give them a try but if they work I’m not sure what experience I’ll gain from running them so I probably won’t be able to help out anyone looking to get these in the future who want to know if they should run them.

I’d take Steve upon his offer, just a thought.

Ok with me. Stock parts are best 99% of the time. Maybe those SMP injectors are the 1@. SMP makes good things. I've got several people who have pm'd me for the stock injectors so if you aren't interested someone else is pleading their case - which I understand. Good stock parts get harder and harder to come by. Off to bed, I'll get back to others in the morning once I dig them out of their box.

So I took one of the injectors out of the bag and removed the hose to get a better look and see if anyone more knowledgeable than me sees anything interesting.
For one, there is no pintle on the standard motor one. The Bosch clone has a needle type tip whereas the new one is just a hole. The hose barb on the clone is 7.93/8.89mm (skinniest/fattest) and the new one is 7.79/9.76mm (skinniest/fattest). The collar to the tip of the new one is 6.82mm, I don’t know what it is one the old one because of the pintle cap. On the old one the length of the tip (end of pintle) to the tip is 31.84mm vs 21.77mm. The reason I bring up the length is because when seated the original will sit about 6mm further into the intake flange va the new one.
The other major difference is that the new has a different style plastic top and makes it so that you cannot slide the injector bracket over the top like you can the originals which makes removing them a pita because you have to take off the rubber bushing first which is now being covered by the injector hold down bracket.

I’m going to return these. Amazon listed them as compatible but smp’s website says they aren’t and lists the correct part as fj634.

Does anyone have experience with these injectors from Bus Depot?

Those look exactly like the ones I purchased except for the hose.

At $96 each on Amazon. Wow. That is like $400 a set. Outrageous. BusDepot ones at $220 a set would be less.

The ones on busdepot are the same ones I already purchased and I got them for $170.

why don't you use them? They should work. They are $55 each now. 4 x $55 = $220 plus shipping. I am sure we will see inflation due to the stimulus spending, and the moving of manufacturing back to the USA, Mexico, Canada , and Europe from China. Back in the late 1970's & 1980, there were a couple years where prices on everything went up 10% to 14% a year. That is on core items, and often items like parts for cars might have gone up 20% a year.

Yes, they are excellent. Except for packaging, they're the same as what NAPA is selling brand new, for about the same price. I'm not sure I buy the diatribe of ad copy though…
Here is a smog report on the last bus I used them on:

little lean Robbie. O2 is left. Anytime there is O2 left, fuel can be added to it to use it up. I try to leave a fraction of a %. If all of it is used up then CO will rise. Also your NOX will come down because the burn will cool down a little. That said, heater temps will cool a little because the EGT will be lower. Your valves will like it more too.
The issue for injectors is that each model has a slightly different volume even though it may be close. For peak performance while still passing smog, the AFM has to be tuned to the injector (and cam).

My main concern was their length as compared to OEM and the fact that smp’s own website says they aren’t the right injector for my bus.

Meaning why not use the Bus Depot injectors you already own?

I've added a note on the original thread with the part numbers:

As this has been revived from another thread, here's some more info about part numbers:
FJ634 - same form factor (and presumably) specs as OEM, L-Jetronic connector. Listed applications: Jaguar XJS (91-84), Nissan 300ZX (86-84), Nissan Maxima (86-85), Volkswagen Campmobile (74), Volkswagen Transporter (79-74), Volkswagen Vanagon (83-80)
https://www.standardbrand.com/en/ecatalog?part=FJ634&type=p&search=s
FJ697 - different pintle style and hose barb than OEM, L-Jetronic connector. Listed applications: Fiat 124 (83-80), Fiat Brava (81-80), Fiat Strada (82-80), Fiat X-1/9 (83-80), Lancia Beta (81)

Presumably the FJ697 injectors are the ones you got and also the ones available from busdepot.
The OEM-like FJ634 injectors seem to be available here under the Echlin brand https://www.napaonline.com/en/p/CRB218532 , possibly the same SMP product with a different package and branding (and same blue connectors as OEM). The price is not listed, so it's not really possible to compare with the Amazon price until you call or e-mail them.

The SMP injector quality is excellent.
I have installed about 3 sets in varioua cars with no changes required for perfect running. Looking at the parts and tips the quality is pretty much equal to Bosch. Ray |

The Napa ones show up as $51.49 for me. Those look like my OEM ones. How is that particular brand.
If it matters the ones I got from amazon are FJ6 not any of these other ones.

The main Napa brand you find is Echlin. They are MADE by SMP.
Same for ignition points. Napa has three levels (actually four but two are in the lower tier). Their top 3 are all made by SMP and are various versions of the Standard Motor Products "Blue Streak" points.
SMP has actually been making injectors for decades. The key as usual is getting the rigjt part #. Five years ago I was skeptical until I spoke to numerous 914 and type 3 guys that used SMP injectors.....and I installed a few sets on my own that have worked superbly.
Those two iniectors pictured....may be the same internally and spec wise. Check the catalog. The plug differences....is just a plug housing difference. Same internal terminal and spacing and they fit the same boots. If need be you can buy the plug housing you need. Ray |
