Rd28 Vs N1 Block Whichever Is Better For A Build?

[GD51LA]

What is the cost of each?

Which is stronger? And how?

What machining is required for the RD to fit the 26head?

We need a comparison for those buying N1 block for strength

Is it worth going RD?

[Leroy Peterson]

a quick google search for SAU came up with enough info to satisfy your question...

"Simply put there is ZERO advantage over an RB30 bottom end. No stronger, DET cylinder head doesn't bolt straight on, water and oil galleries are different, as is water pump and oil pump etc etc."

more comparable to RB30 block than RB26.

so of course RD28 is a lot cheaper than N1. and cheaper than RB30. with good reason.

That search is a pile of shit..from 2007 no less .. but if you have to ask about a RD...you dont need one

Just out of curiousity why do people go rd28?

[GTSBoy]

Because race car.

Um. Because diesel. Yeah that must be it. (The story is that they are strong.)

[niZmO_Man]

RB30E 4 lyf.

[WantGTR]

RB30E 4 lyf.

My thoughts exactly....

People go rd28

Because rb30 blocks split

Same with any platform of engine,some people can get them

To hold together better than others.

unless you want a 7 sec car,you probally dont

need one at all

Another thought, how many RD28 in NZ and Saudi compared to Australia?

Quite a few in NZ. Was someone building a race engine out of one locally - don't know how it turned out.

The RD block needs a heap of work to make the RB head fit but it can be done.
We are actually doing one in the new year with a 3.2 stroker.

The deck is thicker and so are the bores, it is one heavy f**ker though.
They can also be bought new which is always a good thing.

Custom crank and rods or is there a drop in kit available for them?

Did you sleeve the block or did you think the extra wall thickness was enough?

What was the biggest issue having the head join the block?

Pic of split rb30 block?

you'll be blowing head gaskets before splitting a block and if you're worried about it then grout fill it.

[Ben C34]

Seriously.

Theres pics of a rb30 split lengthwise pretty much at the base of the tapped holes for the head studs floating around the net.

Grout filling won't stop that!

[Ben C34]

Which is a 7 second car.
