Anyone ever fitted top feed injectors to thier zed??

I know they require custom fuel rails and such ...just wondering if its ever been done.

yes, I have done it using skyline topfeed injectors and it works fine.

 

it's a cheap solution, but won't win a beauty contest though :D

 

it's similar to the injector setup on the Z31, which uses topfeed injectors also.

The fuelrail is on top of the plenum, with small hoses running to the injectors.

 

I don't have any pictures of my setup, but it looks very similar to this:

 

hoses running from the injectors:

 

and with plenum installed , with the 2 fuelrails on top:

I take it the fuel rails on top are more or less straight tubes with spigots for injectors and feeds for fuel

 

Did you make your own rails ?

I used an universal fuel rail like this one

and some universal rail adapters

fitting:

its a great fix if you want to go big power and fit say 1000cc injectors from a skyline :)

 

how did you fix the rails to the plenum eric?

currently with zip ties :D

 

but I'll have some fittings welded to the plenum so I can secure the rails better and it will look nicer :)
