Inlet Manifold Spacer With Springs

[grim32]

Hi guys i just picked up an rb25 from a local importer and discovered a weird inlet spacer. You can see in the pics there are 2 springs that look like they get in the way of where the injector will fire, it also has several wires coming out of it that runs into a non standard looking plug. Has anyone seen anything like this?

Any other pics? Im guessing its not an RB25 manifold. More like an RB20 red top manifold?!?!

Not sure what it is but its not a redtop spacer/sandwich plate Roy. The redtop 20s had a 12 port spacer with a butterfly on every second port.

Interested to know what it is though...

Ok here are some more pics. It looks like it has 2 metal plates and the center is some sort of hard silicon. It lines up directly with the manifold so it doesnt appear to be an adaptor. It is an r32 motor and had end feed injectors like the rb20. It looks like the injectors fire directly onto the top spring and the plate is about half inch thick.

The only thing i can think of is some sort of cold start device if the motor came from around the mountains but who knows?

Looks like the same sort a thing they use in diesal engines to get em running when it cold a pre heater

I'll second that idea!

Coil/spring thing should probably heat up the fuel entering the chamber. I think some of the RB's have the water lines running around the throttle body to heat up the fuel... do the RB20's not have that perhaps?

Looking at it it isnt an RB25DET manifold

Yeah its a non turbo motor
