Safe is a strong word, and its dyno, tune and which rb25 you have dependant. A neo can be happy around 500whp, and a s1,s2 I wouldnt run past 450whp (on e85). Pump fuel, 350-400 I think would be your limits. Key things to make them live longer, if you can, put a set of billet oil pump gears in, that'll make a world of difference, add a head drain and put on a baffled sump, with your boost curve, keep it relatively soft in the 4000-5500 rpm range. Bringing them on super hard is what kills them. No it wont be as fast or feel as fast, but itl live longer (we do the same on my 800hp set up with a built motor and all the goodies for that exact reason)
@@rcdemail404 just reliability mate. They sre prone to cracking and failing in the upper rpm bands once you stsrt pushing more than 350 and especially if you enjoy limiter. My stovk motor lived at 400-450 for about 12 months before it shat the can with stock oil pump
Sounds so good!
