Ian is going to need some injectors for an SDS install. This will be based on a 2.0 Djet intake so he'd rather not mess with fuel rails, so they have to clamp in like stock injectors.
Pretty sure there was a thread that used MB or Volvo injectors that were close to the 2.0 green injectors? Low or high impedance, doesn't matter, I can add a resistor pack.

Engine 2056cc, stock 2.0 other than KB 96mm P&C's and Web 73 FI cam.

Thanks

Hi Mark,

I think this is what you are looking for:

If SDS can run with high impedance injectors take a look at these:

I usually prefer these when going aftermarket ECUs with the stock intake runners.

No resistors needed, better electrical connectors, better atomization/higher pressure. Does require a different pressure regulator (though that is pretty easy to come by) Plus they come with a full datasheet and voltage/response time map so there is no guessing with aftermarket injection.

Is the the 280cc suffice or do you really need 380cc for 2056 or anything smaller?

Thanks for your input

Depends on how crazy your 2056 is I guess, but 280cc is still going to still be on the large side for most naturally asperated motors near that displacement. 280cc should support in the ballpark of ~180 HP at the crank.

Forgot to mention the injector sizing is another advantage of these over stock injectors. Stock 2.0 injectors are HUGE. This becomes really apparent with aftermarket systems where you can monitor your pulse width. Extremely small pulse widths results in poor resolution for mixture control at idle. In fact i find even the stock 1.7 injectors preferable to the stock 2.0 ones when running an aftermarket ECU on most motors.

Agreed.
But is the single pintle design really giving a better spray pattern then the Delphi Lucas type (3 hole pattern)?
Just curious...
