Hello All,

I have a '90 L98 with 120K miles and it is using the original injectors. I figure that it is time to freshen them up a bit, maybe recover some long lost ponies. I have heard and read good things about getting them blueprinted, do any of you have experience with this? What did you think? I know that TPIS does it, Marren Motorsports is another one, and there is a high performance diesel shop that does it as well. I can't remember their name at the moment. Do any of you have any suggestions on what shop to send them to?

Thanks in advance,

Adam.

 

Hello Adam, buy replacements from Fuel Injector Connection (FIC). Jon there is a great guy.

Go to www.fuelinjectorconnection.com

(NOT fuelinjectionconnection.com!)

I haven't heard of blueprinting injectors. One can not take them apart anyway, so I don't know what you would blueprint. I think that is probably a hype word being used by some places to sound better. Five O mentions this on their website (along with lots of bad spelling), but they don't say what it is other than cleaning and checking flows.

If you have the gray Mulititec Rochesters, don't even mess with getting them serviced. Don't let anyone tell you they can "rebuild" them. They are going to go bad on you eventually and if you are going to go through the intense labor of taking them out, it is not worth putting the originals back in. If you REALLY want your old ones checked for some reason, I am sure they will be glad to do this if you send them in. But, most places wont even service or sell the Multitecs.

Most people are replacing these with Bosch / Ford units and they work great. John has type 3 Bosch for about 160 for a set. Earlier Bosch type are available also and they work fine also. You will get a set of matched injectors as far as flow with a data sheet showing the fuel flow runs. Generally speaking, his injectors are from low mileage Ford engines that are being converted to Motorsports engines.

Remember that no one is actually rebuilding injectors in the conventional definition of taking them all the way apart. They are sealed units. Can't be done. What everyone is doing is checking the flows on an Asnu type machine, ultrasonically cleaning them, testing the coils and then replacing the filter baskets, orings and heat shields.

Hope this helps!

Why replace your used injectors with used injectors? Buy new ones. How do you know how many miles are on these used Ford injectors? How do you know if they have 100,000 on them. When he cleans and spray paints them they look new but they can be in worse condition than the ones your replacing. The rebuilders clean a used injector that's all. They will take your used injectors as core replacements and sell them to somone else. Someone here could end up with your old injectors. This make sense to some. One thing I have noticed on this forum is: almost every member including myself have had some trouble with rebuilts and Accel. Blueprinting is BS, they clean them.

Hope I spelled everything right.

 

he may be refering to flow testing/matching or cleaning.. these guys have been in the business for a long time.. prices are reasonable.. http://cruzinperformance.com/fuelinj.html

 

From what I have heard and read about Rich, I would recommend him. His website shows that he cleans and checks to assure that the injectors are in good condition. He doesn't make any false claims. Other forum members have sent him injectors and he has cleaned them and reconditioned them. Members have had very good results at a very good price. He seems very honest. If you have the Multecs they may not be worth the hassle.

 

Thanks for the suggestions guys, appreciate it. I was under the impression that you could balance the flows of injectors, doesn't sound like that is possible with this style of injector, is that correct?

 

Correct, I would not buy used, rebuilts or Accel. You could contact Rich (see above) or you could do what I just did, buy new injectors. Make sure you stay away from the so called rebuilders. They clean and paint old injectors and sell them as new. There are a lot of them on Ebay. Fiveomotorsports has a horrible reputation.

 

Flow matching usually means measuring the flow of several injectors in a lot and picking 4, 6, 8, etc. that are the closest to each other. BTW your injectors can't be rebuilt.

 

For those that believe that the so called rebuilders can sell NEW Bosch injectors. Here is a link to the site where you find an authorized dealer. Fiveomotorsports claims that he sells NEW Bosch injectors. If that were true he would be listed on their website. The zipcode for fiveo is 90714. Plug that into the Bosche website. Check out the other rebuilders and see if they are authorized Bosch dealer. Some of the dealers won't give you their address. They just sell on Ebay. It looks like the only place to buy the NEW Bosch injector in fiveomotorsports area is Autozone. What I find amazing is I reported fiveomotorsports to the California Attorney General's Office for fraud. I got my money back but he continues to say he sells NEW Bosch injectors. I just tried the zipcde for the fuel injection connection, it's 30040. They are not an authorized dealer. They cannot sell NEW Bosch injectors but they claim they have them for sale. They cannot issue a Bosch factory warranty. The internet is not regulated by anyone. Anyone can open an Ebay store and commit fraud all day long.

Dude you have got to move on.

 

summit sells NEW ford/bosch flow matched #24's and TPIS sells NEW matched ones as well. What they do is flow them at the same pressure and pick ones with numbers that are close or the same. Fords come w/a flow sheet and TPIS engraves the the # (using a different method) on the side of the inj.

 

Summit racing and TPIS are good places to shop. Are you sure the Fords are really Bosch or are they the Bosch type? I don't think the Fords are very high quality and they are noisy.

 

I know, I just get pissed when someone recommends five0. Makes me crazy.

 

Ford does not make injectors. They are made by Bosch for the most part. Noisy? you can hear Bosch injectors click more if you have the hood open and are standing close to the engine. Can't tell any different with the hood closed, so who cares? They are efficient, high quality injectors.

Other than that dont let a place like five0 destroy the reputation of everyone out there. Call John at FIC for example and let him tell you about his products. Reputable places don't ask for your Multitec cores and will not resell them. Mechanically, not much go wrong with Bosch, Delphi and others beside Mulitecs. Restrictions caused by dirt and varnish cause the injectors flow unevenly or even stick open. If you ohm test a coil both cold and hot and also put it under a load test, it is good to go for an indefinite time (again this does not include Multitecs). Other than the coil, the injectors are made of very hard and durable material. Blasting the varnish and dirt out by ultrasonically cleaning them usually bring them back to correct flow just like textbook. Good quality brand injectors like Bosch that have been serviced are really a great value.

Anyway, now that we have probably beat that to death, sure, go with new ones if you can afford them. If you want or need a good value, there are places that offer a high quality alternative, just be careful and read alot about who the players are and what they offer. Words like blueprinting (what does that mean anyway) is not legitimate.

BINGO, a winna.

Yes, Rich can and will balance flow.

 

Actually no one can balance the flow (adjust the flow) of a (gas) injector and Rich's website points this out. What he can sell you is a group of injectors that the flow is the same or very close. This could be called a balanced set. In other words if your injectors do not flow close enough together after cleaning then you have to exchange them for ones that do.

Not trying to cause a big argument here, I just think it is time that definitions of words that everyone is throwing around be cleared up to reality.

 

Here is a Sorenson injector for sale. I don't know much about them but they are new and come with a ! year warranty. They are only About $42.00 each. I have seached for new injectors for my Vette. They range between this unit up to about $110.00 each for the Bosch. I went with the Lucas because they have a good reputation. They put them in Rolls Royces. Maybe someone knows about Sorenson. It's seems like an alternative to the Accels and the rebuilts. I'm starting a new thread to see if anyone know about them.

Thanks to all of you, this has cleared up some misconceptions on my part.

 

I just got to put my 2 cents in. I would go with FIC. They carry a 3 year warranty. Read everything he has on his site. www.fuelinjectorconnection.com I think when they are flow balance, or matched, what they do is measure the flow, and certain flow rates go into a bin with identical units. That way they are all closely matched units. Anyway, I will be going with FIC, heard many others have, and they where very pleased. I was going to go with the Accel's, but I have heard to many guys where having trouble with they cars loading up or running rich. Seems you can only get 19 or 24lb injectors from Accel, and not the 22lb some of us need.

 

Thanks for info about people selling cleaned injectors as "New". I will be careful when I need new ones.

I'm no expert, but I would think there would be some wear on the moving parts after 120K when you think how many times a second those injectors are pulsed. Cleaning worn parts really seems like a waste of time and energy. I'd buy new.
