4agze fuel rail
Car - Datsun 1200 ute
motor / part in question - 4agze fuel rail
problem - no problem yet
occurs/started when (if applicable)-NA
personal situation (if applicable)- I have a 4agze I have re built. I has a Mad dat fuel system, 550cc injectors,264 cams, 68mm throttle body, 5557 pression turbo.
I am only a novice at this but I suspect the standard fuel rail is to small.Does anybody make after market fuel rails for the 4agze big port head.

I take it you're just using the standard big port RWD inlet manifold? Can you just use a (bigger) fuel rail to suit that? I'm sure someone must make one. <-ebay blue top fuel rail.
On the other hand, I'd take it that you're gonna make ~370hp with 4 550's, which I think is fine for standard 4a rails.
But as a disclaimer, I'm no expert on this stuff. I remember there was something different about gze rails from NA bigport stuff, or was that smallport, I forget.
As far as I know the only fuel rail difference on 4AGEs (ok, the 16Vs) in bigport vs smallport. The injector spacing is different. GZE and GE have different fuel pressure regs (GE being slightly higher pressure funnily enough). But I guess you won't be using the factory FPR anyway.
I've never heard of anyone running into problems with the stock fuel rail, though that is by no means gospel.
