Left is stock Smallport's. Right is 13B's which is usually found in 2nd Gen RX7. Length-wise, they look like a direct swap.
A bit difficult to see but judging from the spray tip shown below, smallport has split stream while 13B has single spray pattern. Let's see if this affects idle speed once i swapped the 13B's in.
Different plugs. Definitely will have to change the connectors so it's not a direct swap afterall.
13B has longer spray tip. I have no idea if this will interfere with air flow inside the manifold but it won't be too worried about that.
The 13B injector shown is part number 195500-1350. This website here says red square plug with the same part number like mine should be low impedance.. but mine is definitely high, confirmed with ohm-meter. Yet another proof that you can't fully trust the interwebs, including this post.
