Thread: Intake manifold aluminium plate

My D2a with seq. injection has been running rough once it warms up (petrol and gas) and my mechanic has found that the aluminium plate the LPG installers put un the manifold to separate the LPG/petrol has a crack in it.

problem is the installer here in Perth has closed down, as well as all the others that used to do the same install (after the subsidies closed down).

does anyone know of a mob over east that does that type of install still, and might be able to help source a replacement plate?

otherwise i'll have to take it to be fabricated from scratch and that's gonna be $$$

cheers

The same way I convert any EFI vehicle, drill the injector nozzles into the inlet manifold adjacent to the petrol injectors, then run the LPG injector hoses to wherever the injectors are mounted. My method for D2's involves passing the hoses through the top section, via holes drilled in the manifold webs:



One D2 conversion I am aware of had all the injectors mounted under the upper section hidden from view. AFAIK the only reason fitters use the sandwich plate is to raise the top section to allow the injection hoses to pass out over the rocker covers. There is no one correct way to do it, simply it is whatever works.
