1.6L td injector options

[Tony2ltr]

I know a guy that put Cat injectors on his newer tdi, says he dyno's at over 400 lb of torque.  I have see the car (automatic) go.  He steps on the pedal, waits about 1.2 second for the boost, then the tires go uncontrollably up in smoke!  I can't verify the dyno numbers, he does some racing development for General Mess though.

Here is a list of nozzles I found,  Does anyone know how to decipher the type number?  the "0" I believe refers to the spray pattern angle which is 0 degrees. and the "S'" refers to pintle design.   :idea:

Yes, the '0' is  the spray angle. You really want to stay with a nozzle that has the same spray angle or you're probably going to end up with atomization issues.

More on injectors from the Bosch injection pump book:
"abbreviated a bit...
1.Throttling pintle nozzles is used on swirl/prechamber/turbulance engines.
2.Injection is coaxial shaped jet of fuel
3.INjector Nozzle type (DN...SD) together with nossle holder type KCA with screw in thread.
4.normal version has M24X2 thread and an A/F dimension of 27mm.
5.injection nozzles have a needle Diameter of 6mm and spray angle of 0 degrees.
6.it is rarer to find defined 12 degree spray angle (in the DN 12 SD) for
7. for restricted cylinder head space more compact nozzle holder versions (e.g., KCE) are avaiable
8. The hole nozzles have needle Diams of 4 and 6mm (for DI engines)
9. the seat/hole nozzle is only available in size "P" version
10. opening pressure of holder and nozzle assembly (IDI) is approx 110-140 bar"
That is all I have found in the bosch book on VE pumps...
hope it helps some.

I went with nozzles from a 80's diesel gmc with good results on a non modified motor. the nozzles were lots cheaper than vw or merc ones too, like ten bucks each.

they will flow way better too, so with a modified pump they should do even better

[Tony2ltr]

have you run it yet??
What kind of injectors were they? for a 6.5, 6.6?
