I am going to buy new injector

I am going to buy new injectors for my '87 Testarossa from Hal Rogers. But first I need to verify that I'm ordering the correct part number. The part number on the ones I removed are: 0 437 502 010. The number I have for the new ones is: 0 437 502 047. Can someone please tell me if this is the latest correct version that I should get? Thank You in advance.

Just a note Jeff: My injector

Just a note Jeff: My injectors are the same number as yours. I e-mailed Rogers, and they quoted $22.50 per injector, and $4.95 for the thick O-ring.

Henry: Was that for the part

Henry: Was that for the part number on the ones I removed, or the number that "someone" said was the latest version of the correct injector? That seems like an awful lot for an o-ring, I wonder if there's an alternative to this?

Jeff: I don't know the cu

Jeff: I don't know the current part number. I was referring to the original injectors, as you also have the same. I haven't ordered any yet....I don't know anything about the replacement injectors.....I was told that they did change numbers, but I don't know to what.

I went to my local VW dealer regarding the O-rings, and he couldn't help me.....the idiot wanted to know the year, and model of the VW!!!!!! Some help!!!!!

If the thick O-ring isn't cracked, or brittle, I plan on re-using mine.

Hank, Jeff and JRV,

The thick o-ring is from a 1977 VW Rabbit with a 1.6 litre engine. I'll work on getting the Bosch PN tomorrow...

JRV: Do you know what kind of

JRV: Do you know what kind of upgrades they did when they changed the part number to '047? I would assume this new version must be better than the old one?

David Feinberg: Wow...that is great information...Thank You so Much! You just never know about parts for these cars, there are so many cross-overs and alternatives. I see the parts stranglehold and price gouging slowly coming to an end some day as long as there good resourceful people who don't accept everything they are told. I would imaging that sites like this one are monitored by Ferrari people and hopefully they take note.

Jeff,
Over 25 years on the s


Jeff,
Over 25 years on the service side, you eventually learn your way around. However, now I'm on the OE consulting side, so information isn't as easy to get for me, as it once was...Calling in a few favors, from time to time...and I've got a good memory, still!

On the injectors, the primary difference between the two numbers, is that the later one has an improved (better shrouded) pintel design...hence, better spray patterns over a longer period of time. Materials may have changed, but the tip is the primary difference.

As for the donut seals...6mm x 5.2mm. Again, two designs...OE likely black, replacement could be black rubber or green viton. Although the viton may be a better design, they can be a real bear to install.

I've contacted my Bosch supplier...and hope to hear back from him later on today.

Regards,
David

I just posted this question a

I just posted this question a couple weeks ago on F-chat, and we found that the injectors are the same for all the similar period F-cars. The upgraded injector part number is 04 37 502 047 As David says, they changed the tip; the easy identification is that the old ones were made of steel, the new ones are from brass. I intend to replace/upgrade the injectors on my 328 as well. The recommeded source is www.importeccatalog.com

You can also search the archives at F-chat for info. on the Bosch website where you can confirm part numbers and applications for the injectors.

Wow...the Importcatalog has a price of 21.15 for the newest version injectors. Does anyone know the part number for the thick o-ring? Maybe they have this part too!

Thank You JRV, David, and Dave!

Jeff,
If the injector donut s


Jeff,
If the injector donut seal (the upper one between the injector and housing is round), the application is the same as VW. See pictures in the Import-Tec Catalog using a 1977 VW Rabbit as your search criteria. Both green and black seals are listed...PN C1010-13920 for the black seal or green PN C1010-19742. Important: Some KE cars used a square donut seal. If this is the case on your car, these are the incorrect o-rings for your application.


Regards,
David

David....don't take this w

David....don't take this wrong, but if you were a woman I'd kiss you! I know I've said it before, but I cannot Thank You enough. My TR takes the round seal. How did you ever figure out the o-rings are the same for a VW and a Ferrari? Are the injectors the same and therefore take the same o-ring? I can't believe that ordering these o-rings from Hal Rogers would cost $4.95 each and from Import Tec they are only 0.31 cents each !!! Henry...are you listening out there? David if your ever in Coldwater, Michigan I owe you a nice dinner.

Bobby Bosch company provides F

Bobby Bosch company provides FI components for virtually every European manufacturer...As special as Ferrari is/can be, they're smart enough to use "off the shelf" Bosch components, where ever possible. FYI, most of the CIS/CIS-E injectors are the same diameter where the seal lip is machined. How'd I figure this out?

Servicing 2,500 foreign cars a year helped...and when I did injectors many years ago on my 328, I saw the seal and thought...Hmmm,these sure do look like VW, BMW or AUDI seals. As we used to buy them 1000 at a pop, supply wasn't an issue.

Most of the other Ferrari FI components can be sourced to, or are the same as MB...though the FD is more or less unique to the Ferrari. Although difficult, they too can be sometimes be sourced outside of the F-car network. Still, not cheap though.

Despite the FI system differneces, the BB I own and your TR have alot more in common than you might suspect.

Jeff...I'm just South of Rochester, NY. Dinner, sure..If you need a hand one day, drop a note and I'll fly up for the day. No big deal to help...Thanks for the offer.

Regards,
David

Just to let you know David I o

Just to let you know David I ordered the injectors and o-rings last night. The grand total including shipping is $257.52. Needless to say I am very happy with this.

David....your a pilot too? You'd fly over here like it's no big deal? That's pretty cool! I'll have to keep that in mind. I never ceased to be amazed by the kindness and generosity of the "good ones" in this hobby.

Henry: I ordered lots of part

Henry: I ordered lots of parts from Rutlands. Very easy to talk to and so far not one bad experience. It seems there is no ONE best source for parts. But if service is good, I'm a repeat customer. That importtecparts place is gonna be a gold mine provided we can get the Bosch part numbers, or cross reference information. Good Luck on dropping that big aluminum lump out of there!

Thanks Jeff: Just curious, did you find the valve adjustments off, and if so, by a lot?

No....they looked okay. It&#3

No....they looked okay. It's kind of hard to check until you get the proper "feel" using the gages. I wrote everything down as to what valve had what clearance. I'm documenting as much as I can, to put the next owner's mind at ease if I sell the car some day. My info. may not be from a dealer and all official-like, but it should help the value somewhat - I hope.

Hey guys, what is the difference between the black and green o-rings? Does it matter which I order?

Dave: Everything I have seen

Dave: Everything I have seen on my 88 TR has been black. I believe the green refers to a "Viton" (as David described) product. I don't know where they use a Viton product on a Ferrari.
