use the ones from your factory rb25 manifold, thats what my friend did on his rb25 when he put the greddy manifold on.

lol, If you read my thread I just did this. I was missing two of them, 300zx 94+ are very close, didn't try them though. KA's both years are WAY to small. I ended up using 5/8" ID heater hose for it to work, no leaks so far.

ha, sorry man don't get on here much lately. i did read page 6 of your thread. so the heater hose cut into pieces fits snug on the manifold? how about the injector?

might be a noob question but are neo injectors different girth than s1 or s2? just curious as to how well it'll seal. i may just pick up a hose tomorrow and go to work. good deal thanks guys

I thought NEO injectors were top feed, so, totally different then S1 and S2.

they are, but the greddy manifold should use the same size, so the inner diameter would be the only concern really. wonder how much a difference there is

Injectors are the same between motors s1 and s2.

The 5/8" actually fits snug around the injector, and there is a little slop on the plenum (I got lucky and found fatter wall thickness heater hose) the actual OD of the stock grommet is like .995 inches, ID was like .565 or something like that.

I cut them to thickness as best I could, and installed. Not leaking anything so far....

A32 Maxima insulators.

part# 16636-72P00 crossed reference them with the JDM# from the JDM Nissan Fast.

Mines came in yesterday. I fitted and measured them so I can indeed confirmed they are the correct size.

NEO 25 injectors appear to be the exact same as VQ35 injectors. At most, the flow rate may vary.
