Rd28 -> Rb28det


280zg

Recommended Posts

I have seen some info somewhere on the net...

Of people converting the diesel engine RD28 with a RB head,

from a RB25/26DET(T).

Does anybody know some more of this?

http://en.wikipedia.org/wiki/Nissan_RD_engine

 

The RD28 is more available in europe, they came in the Laurel

and Patrol, ca -90 models +/- some years.

And, I was thinking of get a head from a RB25DET,

and put it on the RD28 engine, building a RB28DET!!!

 

Could someone tell me if this would be a good engine,

or is there some reason for this engine to break down, or give poor power?

Would the diesel crank or other internals be no good?

The wikipedia don`t say if this would be a bolt on head...

I already have a autronic smc in my z, so there would be no problem

in controlling the engine.

 

Also, what kind of transmission would fit this engine?

The best would be if an transmission from a RB-powered skyline would fit.

Internals and such might be a problem but your biggest problem is going to be the head. I've never seen an aluminum diesel head and most are going to be cast iron. If you wanted to just slap a turbo on the current diesel. Would be much easier to do. It also depends a lot on how much HP you want to make.

Well, I'v read about that somewhere too but can't remember where.

I do remember that the tranny is compatible and the head bolts right up.

The block is heavier though, to witstand the high compression of the diesel stroke.

 

Anyways, I'll try to find that site again and I'll send you the info.

VW, Audi, and MB all use aluminum heads on thier passenger diesel cars, and have since the mid 70's.
