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 ;)

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
