Hi,

It stated on wikipedia that the Nissan RD28 Diesel engine is very similar to an rb block, but obviously diesel and single-cam. And that some ppl have used a custom head to convert to standard petrol.

Does anyone know if a RB Head will bolt on to a RD28 block?

If it does, then wouldn't it be a good option? aren't diesel blocks usually stronger?

Nissan RD28 Diesel

Bore: 85mm (guessing you would bore it out to 86mm if you have to)

Stroke: 83mm

Isn't it better that a rb30?

RD28 - Stroke: 83.0 mm

RB26 - Stroke: 73.7 mm

RB30 - Stroke: 85.0 mm

lol, personally I wouldn't want an 85mm stroke either. but you do have a point about it comparing favourably to a 30 crank and rods in that respect.

I have no idea if this thing is feasible for a performance application though, and also not sure how comon they are?

Old news, very old news. 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.

I see nothing wrong with an 85 mm stroke and 86 mm bore (as in RB30), that's a pretty "square" engine (bore = stroke). Same as a BMW 3 litre 6 (as in M3) or a Toyota 2JZ. Neither of which are exactly bad engines. And of course an SR20 is 86 x 86 as well.

:P cheers ;)

      How dare you sell your unreliable Skyline and buy a reliable, Toyota/Yamaha car with a strong gearbox, torsen LSD and Toyota reliability. At least you won't need to worry about oil pumps, big catch can, oil restrictors, blowing off power steering belts, sheering off 3rd gear, failing ABS relays/pumps, etc.

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      Leak from Tokico BM50 Brake Master Cylinder

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
