Ok so I need some help here. It seams that the stock Nissan injectors arent that easy to identify or at least im getting my ass kicked trying. Here's what I know.<br />
<br />
High impedence<br />
<br />
Off of an 88 Z31<br />
<br />
Visible part number is 2341 64 01 and A46-000001<br />
<br />
What I need to know is are they turbo or na?<br />
<br />

**Disclaimer about JECS numbers. These numbers do not represent a Part Number, but yet a manufacture date and batch codes. There is no way to tell the flow rate of a JECS injector by the number alone! Color, connectors, and style are a "better" way to determine the injector you have.<br />

^ what Vagabond said.<br />
<br />
Only way to tell the yellow top side feeds apart is to break on off and have it flow tested.<br />

There is info I found somewhere around the interwebs that post service campaign side feed injectors all look the same, "natural" (yellowish with age) but I can't confirm that.<br />
<br />
These are pics of my actual injectors.<br />

I can, NA and turbo campaign side feeds look the same. if you ask RJ, they're NATURAL not yellow :P<br />
<br />

<br />
Ah, then yellowed with age. Thanks, I'll change that.<br />
<br />
Any one want to confirm that older side feed turbo injectors were brownish/burgundy?<br />
<br />
