i saw the Xcessive Motorsports fuel rail i think that only can work wit the Xcessive Motorsports lim but, i saw you can past from 2 to 1 fuel rail allowing the secondaries and primaries in 1 rail only i think that is great upgrade to do.
but i dont know if you can put diferent sizes of injectors like 2 850cc and 2 1600cc in the same rail,let me know what you think.

thanks

 

Im not sure exactly what you are trying to do. but if your just trying to upgrade your fuel system I would try www.KGParts.com. I know there kit works with the factory LIM. There is actually a group buy in the works as well if you are interested.

I'd say that your idle would probably suffer if you eliminated the primary rail altogether and moved the primary injectors up a few inches...the primaries were placed directly adjacent to the ports for a reason on ALL of the fuel inected rotaries...

 

I think the GZ Lim is intended for people who want options to run 4 Top fed 1680's... I mean if you're paying $500 + for a part the last thing you wan is to be limited...

It's for like a dragster single running 20-30 psi boost, and needs the extra fuel.... in addition to being able to idle... it's more options, not neccisarily more = better.... unless you're building a dragger... or dyno queen....
