How Much Can An Rb26 Rev Out To Safely?

[nsta]

Hey guys, im getting my motor rebuilt at the moment, back to factory specs, car already has acl pistons -.5mm oversize, larger turbos, everything else stock, bar arc panel filter plus cold air box, and exhaust....what is the safe limit for the rb26std when it comes to revs, ive heard ~7000rpm?, others seem to also believe that the stock gauge is always off by around 400rpm?

thanks- ive tried searching about this with no luck....just want to know others thoughts

wouldn't go past 8000 with the standard valve guides in a 32

Would it be better to have it tuned to say 7000/7500rpm, either way i dont think theres much power to be made after 7000 on a stock gtr....

[sh@un]

put it this way- with standard cams, you can make all the power you can below 8000rpm anyway

p.s the standard rev cut on a 32 is 7500

no mine revs to 8200 rpm

i wouldnt go much past 7500 on a stock motor/rod bolts etc.

Just undue risk if the motor is old, wont make much power there anyhow unless you have big turbos, and then... you've have a proper bottom end by then

Well whats the oil pump that you are running ? I am assuming its a standard one..I would not really be trying to rev it past 7500 definately not 8200 like you said.As that will more than likely be your first thing to go bang..then spun bearing shortly after...You want it to rev no problem..build it to live

How can you diagnoise whether you have a spun earing or not, or whether the oil pump has gone bang?, my gasket blew, but it wasnt because ov over-revving, but none the less im trying to diagnose the fault....My car still was running when the gasket blew so hopefully i havent done damage to the bottom end...i also had oil in the sytem(just milky oil)....ive opened up the head anyhow, so is there anyway i can tell if my oil pump is shot w/o opening the block?
