. Ideal for a big electric power Establish needing dependability and the likely to spool up a large turbo with no breaking a sweat.
Therefore you’re considering an RB28 Create. As with every engine mod, The task gained’t be as simple, Unless of course you receive it completed from a store.
On this page, we’ll get an in depth look at the RB28 and explore its several iterations, such as the RB-X GT2 and the greater frequent RB28 stroker.
Nissan’s greatest recognized 4 cylinder engine has an enormous worldwide tuning scene guiding it, and we teach you The nice, and negative details, of tuning the SR20DET engine.
