rb26dett all the way m8. they sound epic on chat, there light, reliable, big power is easily acheivable.
also the YBs been done, and i dont care for the engine much anyway. sounds abit pants and on the same budget as a 600bhp rb26 ul have an ureliable 450bhp.
rb26 looks cooler aswel with two fat turbos stickin out of it
