RB28 CP Pistons - $1,200

I have brand new (never out of the box) RB28 Pistons. These are to suit any RB26 stroker crank that uses standard rod length but alters the pin height of the piston (eg HKS, Spool, Nitto etc).

Specs are:

  • 86.5mm diameter
  • 9.0 : 1 compression ratio
  • 21mm wrist pin included
  • Carillo rings included


Perfect for 98 or E85 fuel and better off boost response than factory 8.7:1 CR.

I'm only selling as I have decided to go higher CR due to running E85 only.

Retail price is now ~$1,750 for these.

I've had a few queries on these and it's easiest to clarify here:

  • These pistons suit standard or aftermarket rods for RB26 engines
  • You will new a new or used block that  hasn't previously been bored so you can take it from the OEM 86mm to 86.5mm.  This still leaves plenty of metal between the cylinders and the water galleries
  • The wrist pin height of the pistons is different from OEM pistons to suit HKS, Nitto, Spool, Brian Crower crankshafts. 

Everything brand new and includes matched rings and pins.

    • Yeh... literally every time i jump on a forum, see an instagram post or see an engine bay at a car show, i get an idea and add it to my 'to do' list. So what started off as, hey can u just make a couple of intake hard pipes because my dumbass bought the wrong apexi kit, blew out into a 2 week job including braided brake lines & custom bash kit for the front lip haha.  Getting Luke from A4E engineering to make a full custom exhaust with a controllable aes dump valve so i can actually switch between quiet and loud, because right now its just loud all day every day. Then after that go and get the tune redone flex e85 & 98 as i get bugger all milage from e85, makes going for longer drivers difficult
    • Car looks clean as. You ended up getting quite a bit done 😂  So what's the plan for the exhaust? 
    • The only Neo rods that were any different to any other RB25 rods were the DET ones, and they were the same as RB26. Here is a Neo DET rod. O5U part number visible. Here is a post in a thread here on SAU with evidence from someone who has done this before. There are photos in the thread of normal RB25 rods.  
    • Sure, but why assume that will be the case forever? And why assume you'll be able to do an oil change to swap back to a stock drain bolt before that happens? And does it even matter when I change the oil at fairly short intervals? Life can be funny sometimes and unexpected things can happen. Like breaking a collarbone so you can't do any work on your car for a few months but the oil change is due so you have to take it to somewhere and hope they don't do something stupid like stacking the new drain plug washer on top of the old one.
    • Do u know how to identify the rods are rb25 or neo ones? Can u look into the pics and tell me is they de or de neo ones. Its confusing becoz my motor has de neo head but block is 25de 75t, so really confusing me about rods, crank.
