Due to the increase in orders “enquire for availability and time frames”

NO LONGER AVAILABLE - "Platinum Prepped" second hand / refurbished RB engine blocks are no longer available due to both scarcity and availability of our new Cast RB26 block which is capable of a 90mm bore allowing for a 3.0 Litre displacement. 

Original listing as follows kept live for reference only: 

Platinum Prepped blocks are a MUST HAVE for any serious RB build and are sonic, hardness, and crack tested for longevity and are suitable for applications between 500 - 1500hp. Beginning life as a second-hand RB30 Block, these blocks are prepped, acid washed, machined, meticulously tested, and come with a detailed report for specifications, tolerances, and test results. Why place the guessing game with expensive rotating assembly when you can let the professionals handle it for you and give you a product that will perform with peace of mind that all checks have been carried out.

Option 1: utilizes a PRP Alloy overlay brace with the options of 2WD or 4WD, Wet/Dry sump, and utilizes OEM Main bolts - recommended for up to 1000hp.
