Changing Injectors.

[Pink_Floyd]

Having removed all my injectors and now waiting for the new O-rings to fix the leak, it just crossed my mind is there any point in changing the injectors for different ones. The chim is a 1998 4Ltr std cam running on the 14cux. Over the winter I intend changing to Megasquirt ao it gives me fule and wasted spark. So If I change the injectors for something else will I notice any difference. Looked through the search and a couple of mentions of using vectra 1.8/2.0 injectors.

You can`t change them untill you fit the Megasquirt

Why ?

Any pintle injector of the correct flow & impedance will be an improvement over the Lucas disc type.

As far as I'm concerned the Vectra injectors have three clear advantages.
1) they are the pintle type
2) They are readily available
3) They are cheap as chips

Why remove & recondition the old Lucas disc type when you can source a set of used Vectra ones and have them reconditioned and flow matched as a set of 8?

So what Vectra ones are a direct replacement for the Lucas ones ?
Are the same injectors fitted to the 4, 4.5 and 5 Ltr engines ?

Thanks to all for your comments and knowledge. I'll be putting the old injectors back in for now and will get some vectra ones (90501588) for the winter ready for the Megasquirt.
