Guys, my 323i injectors are clogged.

I can not 323 injectors on a few sites.
Are 320i bosch injectors from 1980-1982 the same as 323i injectors?
I heard that they where..

Can anyone confirm this?

thanks.

You do the math.

You do the math.

CJ, thanks. I heard that they where..and I do need another set.
Mine I shot. I also heard that the injectors I need are from an 80-82 320i.

thanks. I will shop around.

J

correct me if im wrong but werent the pre 80's e21's carberated so wouldnt they not have injectors?

yes, you are wrong. any e21 that had "i" on the end of its model name had fuel injection.
Jake

77-83 320i were k-jet

the 320/6 was carbed

oh i thought only the post 80's e21's were k-jet. no e21's with the m10 came carbed from BMW?

No NA E21's with the M10 were carbed, however the Alpina A1 320 (7/75-8/77) came with the Solex 40 ADDHE; and A2 320 (7/75-8/77) came with the Solex 45 DDH

The Euro >1980 320/4, 318, and 316 came with the Solex DIDTA 32/32

The Euro 1980> 320/6 came with the Solex 4A1, the 316 came with the Solex 2B4, and the 315 came with the Solex 1B2.

Pat where did you get those part numbers from? I got mine from BavAutos web site and they usually go with BMW part numbers, either way they are the same on a few sites I have checked out.

Guys, my 323i injectors are clogged.

If you want to save yourself a few bucks you could get them cleaned...

Josh how do you do this? Do you soak them in solvent or something?
I was thinking about just cleaning them, becasue I want to spend the mola on the mustang 19lb injectors..

Do the math and all will become clear:lol

No, you can't soak them in solvent, they are cleaned with an ultra sonic cleaning machine.

I can use google. Here's the first web site I pulled up, typed in "clean cis injectors". They do CIS injectors. I get a gold star.
injectorservices (http://www.injectorservices.com/)

I would not spend a ton of mula on the 19 lb mustang injectors either. Those will be a dime a dozen, buy used ones for cheap and get them cleaned.

Are you sure that your injectors are clogged? Have you replaced the fuel filter or checked for fuel flow at the injectors? I would be more worried about the fuel distributor than the injectors. My car started running on 3 cylinders before I tucked it in for the winter, but I haven't had the time to determine whether its the injector or a bad port on the FD. Speaking of which, does anyone know where to get the tool to remove the injectors? I looked at bavauto and bmp and can't find it, but I know i've seen them.

according to RealOEM.com:

320i = 1 35 312 61 685

323i = 1 35 312 66 436

Are those even BMW part numbers? WTF?

You do the math.

What Cj listed as part numbers, Bav auto also gave me.
So basically 80-82 injectors from a 320i = 323i.

yeah, that's definitely a BMW part number...well, just the injector part numbers from the 323i and 320i added together. CJ, you said to do the math.
Jake

Joe,

The injectors have different part numbers in the ETK. I know of folks who have used 323 injectors in 320 with no performance difference. I also know of 323 owners who have used Porsche 911 injectors. I suspect the flow rates are very close but the opening pressures are all the same.

I had mine cleaned by Cruzn Performance. He no longer does CIS injectors. Any competent truck diesel shop will have the equiptment to clean CIS injectors. All you are doing is cleaning as they really can't be tweaked. They have an opening pressure that allows the flow. My cleaning did help however and they documented the flow rates pre & post cleaning.

However I am confused, what do the Ford EF injectors have to do with the CIS? They wont work together. CIS is purely a high pressure flow system that atomizes the fuel. There is no pulsing of the injectors as they flow constantly.

Bruce

Most any independant BMW, Volvo, or watercooled VW shop has the Bosch cleaning machine. I paid less than $40 to get mine cleaned and it made a very noticable difference in the way the engine ran.

Regarding the 19lb efi injectors... you won't be able to fuel much more than about 150hp with those at 80% duty cycle unless you REALLY crank up the fuel pressure. Heck, I run 26lb Delphi injectors at 45psi in my m10-works great.

Bruce. Thanks bro.
There are two things going on.
#1) My 323i injectors are clogged and maybe my fuel distributor is not good.
Anyway, my 323i existing engine is having problems.
This is due to the fact its sat for a decade.
The gas tanks have been cleaned and droped within the last year,
so its not that.

#2) Ken, Bruce all: Those Mustang 19lb injectors are for my - New engine ;) that I have almost built for my 323i. Its the one that you guys like to tease me about and uses the motronic setup from the 325i. With this you a very common upgrade is the mustang injectors which are 19lbs. I dont want to buy new injectors for my 323i if I am swapping engines soon.

With the 2.8 or greater m20s owners swap injectors due to the flow rate on the stock ones. Its a very common upgrade, and I am doing it right from the start.
Acccording to Jordan on Rev Limited he knows the cycle rate of the stock injectors and they can be upgraded.
The picture is of the Mustang II 19 injectors that he is running.

#3) Josh no idea how makes that tool, to pull the injectors but I have seen it somewhere.

J

Joe,

I personally think the 19lb injectors on a Motronic 1.0 are a waste of money. Unless you are matching the increased fuel flow by allowing the engine to breath via more intake and cam timing what is the point?

This comment isn't directed at you but many "experts" out there don't have a clue. Engine upgrades must be approached on a system basis.

The early Motronic isn't adaptive, are you going to MegaSlop?

Bruce, I have heard that Motronic adapts to the 19lb injectors very easily.

As far as upgrading the head/engine, you know the build of the lower end. I am regrinding the stock cam to 272 duration. Do to all the ribbing I take, I am not going to list my other things I am doing to the head, but its going to be built to the max. I have a 288 cam but I can not run it with motronic, so I have to either dump it or find a different engine management system..

I dont like and would not put megasquirt on my tricycle..

Joe,

I am not advocating Megasquirt as I have no firsthand experiance with it. What I do know is that it is a true DIY with a fair amoount of fiddle factor to get setup. Either you have the skills or you have a checkbook.

One fast thought; if the Motronic can't adapt to the 288 cam how does it adapt to the 19lb injectors?

Bruce, I have looked into this and every available motorswap and tuning trick for my car for a while.
Also I have talked to Jordan, Tyler Brown. Rob and Gordon of Bav Auto, Turner Motorsport, Jim at Metric Mechanic
and a whole bunch of others like Tony at VAC, Pete McHenry and Kemit Upton.

If you go on Rev Limited and ask Jordan this he will smile. :D
There are some cams that you can run on the m20, with motronic like what BMP sells that intake and exhaust durations are different.
And some people may run a bigger than 272 cam combo like what BMP sells. But, motronic does according to Tyler who tried like anything bigger than 272.
288 duration is just way too much. But not for guys with the stock 323i fuel system. They can run a 288 cam all day long.
Rob at bav auto is running tripple side draft carbs and a 288 cam, but I dont need this on my car.

Now as far as the 19lb mustang injectors, this mod has been done, by a great number of owners to their satifaction on other boards.
Along with using a M30 MAF and other things. Here are the links to Jordan's car, and to Rev Limited board.

I don't have the time to mess around with Megasquirt.
I am just going to run Motronic this time around.
I am waiting to see what the Neek is going to be running for a stand alone system.
And Autronic is too expensive for me. If I built an even bigger engine or something, maybe I will do something different.

I just want to run my car and enjoy it right now.
