Thank you Rik,
Well, i won't need them now but may be later for a NA application over 200 Bhp.
However i read the following on the ZZ performance page for their supercharger kits:
2. The LSJ uses 34# multec 2 connection injectors. These will not plug into your 2.2/2.4 harness. They are too small for this application. Our kit includes 39# injectors that plug in with no cutting or splicing.

and it makes me wondering about the fact that they could be used as is
