DrR34Gtr · May 7

RB26 JE pistons to suit 2.8 stroker crank 77.7mm and 86.5mm bore

Custom made with EN plating and Je perfect skirt.

Valve pockets Suits 1mm over valves biggest lift you can throw at them. 21mm 210” wall 9310 upgraded wrist pins to suit standard sized 121.5mm rods.

I had these made for my build but block had to be rebored to a larger size so sadly I can no longer use them. I spent a-lot of time and money on these pistons.

See photos these are the Heavy duty forging in 2618 material with all the bells and whistles accumulator grooves double force fed pin oilers skirt milling window milling etc.

The En plating was done to the whole piston this helps with heat and also critically in the ring grooves to prevent ring micro welding. The Perfect skirt is JE's propriety coating its a permanent coating that expands and contracts with the bore to prevent piston slap and noise and also friction. you can look these features up.

They have been balanced to a tenth of a gram at my expense. They come with Gas nitrided ring pack's and oil ring rail supports all brand new never used.

The Dome volume is 17.9 cc which based on your Gasket thickness and chamber volume can put you anywhere you like in terms of Comp ratio in my case it was just under 9:1 but this is highly customizable for your build.

In terms of sizing these pistons will work with any 77.7mm build using the normal sized rods.

I did buy an extra set of rings at the time of purchase incase i stuffed one up during gapping so i will throw these in at my expense.

I purchased these through performance wholesale in Brisbane and still have the receipt if you were to make these now it would cost more then double what i have them listed for.

I am super fussy when it comes to building motors so you will see they have been measured and numbered with marker in the photos. Every thing has been handled and stored with the utmost care and diligence.
