I have a 73 2.0 4, all original except for fatter tires and an updated stereo, need a new injector, will a 75-76 injector work?

Yes

What is the difference? I noticed in my confirmation e-mail from AA that I was getting the 75-76 injector, I thought maybe I ordered it wrong, if it doesn't matter then I will just use it as I am not driving the car right now because of the leaking injector. We only have so much summer where I live and I hate to lose the warm days!

.....You said 2.0?.....if it's green

The difference would be in the flow rate in lbs/hr, cc/min, etc

'75 - '76 Bosch Injector was/is a 0 280 150 038 - 400cc @ 3 bar

'73 - '74 Bosch Injector was/is a 0 280 150 019 - 406cc @ 3 bar

'75 - '76 914 had a smog pump & catalytic converter and were made to run leaner than the earlier ones.

Oops, found some info & noted above. I feel better now!

Mine are green and the pictures in the AA website show them as green, but the 75-76 one has an A at the end of the part number.

Better send it back and the get the one for a 73, any difference between new and rebuilt other than the price?

Ian

.....But yes......have them all the same (flow rate etc-etc-etc)

019 Injector carries a part number of 039 906 031 (Porsche/VW '72 - '75)

038 Injector carries a part number of 039 906 031 A

The flow figures I quoted are from a rebuilder. Testing them at 3 bar (44.1 psig) is a bit stiff as the sustem runs at 28 - 30 psig. So the flow rate will be less by 33% at the least, giving a flow at system pressure of 268 for the 038 and 272 for the 019.

What's the flow rate for a 76 912E injector ? I've been told that my 75 L-Jet which has a 2L crank 96mm pistons might run stronger with the 912E injector. Does this sound right ?

So, those with a '75/'76 2.0 who have removed the smog pump and back dated the exhaust system to '73/'74 specs, should use the 019? (except for the CA guys with '76's)

We are talking about a 1.5% difference in flow as rated for a NEW injector.
again, Yes it'll work

According to the chart, they are 188 cc @ 3 bar. 0 280 150 105 as I remember. Looks really lean to me in comparison.

I believe that L-jet squirts each injector twice during a full camshaft revolution, instead of just once like D-jet does.

The numbers quoted are probably from WitchHunter.
BOSH claims that both injectors quoted above have the same flow rate.
See attached original specification.

SLITS, whatever you're smoking, you better give me some too!

Numbers are from WitchHunter & I know the machine they are derived from. Glad you found a chart ... been looking for a long time for kicks as I just use the correct injector for the application. Never looked for "free" power boost as I figure the engineers probably knew what they were doing.

Not smoking or drinking anything ... gave it up again as a lost cause.

Ordered the correct injector, I hope AA doesn't get too upset with me for ordering the wrong one, the only difference was an A at the end of the part number for the 75/76, still my mistake though!
