I am starting a project and need a little help. I am looking to find out what is the #poundage and flowrate as well as duty cycle of OEM S2 injectors as well as 944 turbo injectors. I also need to know how much the oem fuel pump for the S2 pumps out as well as the OEM fuel pressure in the rail.

thanks

The turbo injectors are something like 34.5.

do a search on darklightnings posts here and in the 951 board. He's put together a few FAQ's recently.

The S2 uses low-ohm (2.2-2.5) injectors while the 951 has mid-ohm (4.5-5.5) injectors. You can use S2 injectors on a 951 with ballast resistor, but 951 injectors won't work on an S2 (at least reliably).

I reicently did some checking on the Bosch injector part number for my 89 S2.
Several FI web sites listed the same number for both S2's and Turbos.
I will post the part number when I get home tonight. --Roy--

I am doing a project and just want to confirm that S2 injectors are 34#

thanks

I recall the S2 uses a 3.5 bar FPR, so I suppose the flow rate of the injectors should be similar to the 951's. The S2 needs to flow fuel for nearly the same HP without the .8 bar pressure change, so they just upped the rail pressure one bar.

Will the 951 injectors work in a 88 N/A???
