looking to rev to ~10,000, is this enough?
I'm in the middle of a new build with my b16 and i'm going to be using a gt35r ... since i've got such a small motor, i'm going to need to rev quite a bit higher than stock to keep deep in the power band after shifts. I'm looking to rev anywhere from 9500-10500 ... which will be determined during tuning and then again after a few consistant passes as the track. This may sound a bit high, but with the b16 crank the piston speed isn't going to be much higher than a GSR at ~9000rpm.
85mm B16 ~9.5:1 c/r
Balanced and polished b16 crank
Eagle Rods, ARP bolts
GSR Head Supertech valve springs, portflow retainers
Will the gsr crank pulley be okay? What about the stock valves and valve guides. Is there anything i'm missing in order to rev this high, or will it be okay. My last setup was the same (smaller bore, higher c/r) and took 9000-9400 all day till I cracked a ringland... Just not sure if 10000 is going to put a lot more stress on it or not. Obviously it won't be taken to 10000 every day, only at the track on weekends and such ... but still - i'd rather be safe than sorry.
Thanks

i would be affraid of the crank pulley and the valves, but if you have springs and retainers that should help. i am in the same boat as you.
launching at 8200, shifting at 9400. trapping about 8800 +-
at MIR the end of this month, i will be shifting at 10.5 +- and see what she does.
simmilar setup, 84mm b16, rev head parts, t3t67ho.

Re: looking to rev to ~10,000, is this enough? (boostedcivicsir)
your thread about your mph is actually the one that got me thinking haha. Either way ... I'm pretty sure i'm running the 5/16 bolts ... i'll have to double check, it's been so long since i even looked at the darn things that i forget ... but i'm almost positive that's which ones they were.
Are you running a damper? i might be picking up some valves soon, just to be on the safe side. I'm just not real sure about the crank pulley now.

yeah i am running the fluidampr street version, i am lazy and keeping ps for now till the engine comes out for the gsr and then ill do a manual rack.
if you are running the 5/16 bolts, that would be enough to scare me.
