I have had this engine running for about a year now, but never posted any details. I know there are a lot of ideas and questions about the RB30…
I am pulling the engine out this week to clean it up and redo some lines.
I can tell you that the RB30 route was all worth it. Spool-up is very quick and power delivery is awesome. I like the twin setup better than the larger single turbo. Here are a few specs.
And, yes, this is an RB26 twin turbo kit on a RB25 head.
