The original design specification for the RB26 crank was in fact 8350 rpm max!!!!!!!!!!!!!!!!
Read between the lines and you can see that you have to choose, drive with care and you can take it to 8500+- but you will wear the bearings out more quickly, take it to 7700ish and you should be fine whatever - depends what you want I guessgtr R33 lee said:mmmmmmm, so wat is the rpm limit say on standard internals....so many varied opinions.....

steve, i have been advised by Richard Bell at Rising Sun that smaller turbos will 100% defenatley cure my high fuel consumption problems.SteveN said:You mention fuel economy. Well different turbos wont change that at all, unless you running on boost all the time.
Mapping, or more to the point GOOD mapping, will sort that.
Sounds to me that low load mapping wasnt done much or at all if the economy is that shocking.
Suprised peak powers so high too, its not like they monster turbos.
