Can I Run Rb25 Greddy Plenum?

[helltd]

not sure if i can but just bought a r33 rb25 greddy plenum to fit to my rb30det

buttttt,i'm running a r32 rb25de non vct head,

and also will be fitting r33 style side feed injectors and rail i've got layin round...

someone please tell me it'll fit or what i can do to make it fit

[helltd]

anyone??

[Wheezy]

its not a direct fit. The R32 RB25 non VCT head is the same configuration as R32 RB20, a plenum for the 20 will fit the 25DE.

[helltd]

is there anything i can do to make it fit?

[Wheezy]

Sure, but IIRC the water pipes underneath and water galleries are different, injectors and fuel rail are different etc.

Look into a KU Engineering or Plazaman if you are set on it.

If I could do it again I probably would have spent the money elsewhere

[helltd]

so i could run the sidefeed r33 style injectors and rail i have then,have you done it before?if so what did you do to mod nwater galleries etc

[Wheezy]

No I have not done it before. I believe that the galleries do NOT line up. IE you would need to make some sort of adpter plate ALA the Blitz one for RB26 intake on RB26.

Its NOT worth it.

Go a custom manifold (KU / Plazaman) or adapt an RB26 one.
