Sorry mate but that's tosh . R33 runs .6 bar if you remove the two stage it runs .6 all the time rather than the .4 bar initially it doesn't increase the boost, the wheels break much below 1.2 the series one r33 only has ceramic exhaust wheels the series two and r34 run ceramic exhaust and fibre intake wheels and are more fragile .8-.85 is the safe limit for both but they can cope with spikes up to 1bar. It's the speed that kills them not heat.
Rods and crank in the rb25 can run 500hp it's the pistons that are the weak point , I ran 1.45 plus 50hp of gas in mine around 475hp, all stock, car ran mid twelves and was tracked as well.
hahahaha its 0.5 stage 1 then 0.7 stage 2 boost. then remove the solinoid and it will go to 0.75/0.8 depending on intake temps etc..
yeah yeah we can go back and forth my car this your car that, we can all go read wiki etc too, but from being around skylines the past 10 years and owning and modding them from complete stock i think its safe to say its one car i know inside out.
BTW mid 12's at 475 isnt something id be bragging about, sure i done 13.2 with 280bhp then at 350bhp i managed 12.4 never ran it after that on timing gear, but was tracked at 431 on the stock rb25 before i swapped it out and build a 500bhp rb26 in it.... but i suppose thats tosh too lol
anyways OP im liking the sticker over the pipe, car is clean fair play.
