Check my other videos for full details but at that point it had a ported head, cam and oversized valves as far as I can remember! For 280hp cam is all you need, plus injectors and good turbo set up.
Anything flows enough with 5 bar boost, getting it to last with that pressure is not so easy, and you'll always benefit from more flow! I ran 4.3bar boost (5.3 absolute) with little over 3 bar back pressure, but engine was fully built with lower compression, stronger rods, cam, springs, valves, ported head, arp head bolts etc, I can't see standard engine taking that much pressure, also for that pressure you need compound turbos
Sweet that'll be good, start at 3.5 bar at most and creep it up keeping an eye for head lift and you should be good 🤙 if you do get head lift roll it back a bit change your studs 1 by 1 and send it at that 🤌
Siiiick 👌
what is all done to engine
