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.

Out of interest, what CR did you go to on the new pistons?

[Gav]

11.0 : 1

Obviously only an estimate as the head gasket thickness and any combustion chamber machining will affect this.

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.
