Mark Shead put 4 1000 cc injectors, iirc they were Siemens on my car and said that was pretty much future proof, I would ask the mapper what brand and size they would spec for the Engine that they are going on as I suspect the way the mapper does the car may determine what to go for. Mark likes a lot of boost on his maps, other mappers do things their way...

I think low and high impedance needs to be matched to the ecu type too???

What power are you going for? Interested to hear the spec.

 

Did you add 2 billet fuel rails? Any pics?

 

 

Ah, it’s his one, he has a nice setup.

Take a look at the Siemens injectors.

 

 

Not seen those but I know very little about injectors, I just do as I am told

 

I have done a little digging on injectors in the last few months, seams that a lot of the Americans don’t rate the Siemens DEKA (poor spray and atomisation?) and highly rate-recommend Bosch EV14 range, I’m no expert but I will be looking to buy Genuine Bosch injectors.

 

 

Do not buy any cheap shite, although if they are genuine Bosch "green giants" as some yanks call them they would be ok. Problem is...even the Chinese are making fake injectors of all the popular types.

So...more importantly how much injector do you need, and do you really need 2 inj per cylinder ?

They can have pros and cons, but unless you're heading north of 180hp per cylinder....there really isnt any need or benefit for 2 inj per cylinder.

Siemens make a lot of good value stuff too in smaller sizes, even they started this website to sell direct because of the plethora of fakes out there

Or more locally, just buy ASNU

But you need to know how much injector and flow you need, and IF you must run 2 inj per cylinder, also to decide how you intend to run them. Staged, blended, other ?

 

You can’t go wrong with the Asnu if you are after 750cc plus injectors
