i would think any good build motor for such as pistons, rods, pins, head work, vavles and cams then will beable to go to 10k all day but other then that i dont think you would want to for a long time. or you go boom

 

Early 4g63 engines had no problem with 10k over revs from missed shifts. The evo has a superior valvetrain that can rev even higher. The pistons on the evo are also much lighter. again making it rev higher safely.
Redline to 8500 not a problem at all. Accidental over revs well over 10k would not be a problem.

 

I go 8200 man! I was racing this gt35 s2000 and believe it or not I hit the limiter in 4th gear. (we were racing on the track)

 

when upgrading rod bolts do you have to go back and re trq them after a few miles or is it a 1 time deal??

 

Ive had mine set at 8K for over a year now an no problems, and there wouldnt be. I have valvesprings/retainers for safety (easier to install while doing cams) so I did them at the time, but yeah no problem at all.

 

humm i would be scared of having the pistion give in. but then again there are people there traping higher then 4th gear so they just turn the max rev up to 8000 8500 and never seen them have a problem.

 

i have spun my rpm's consistantly to 8k all last year & it was fine... stock springs,valves & rod bolts.

 

8k w stock head beside buddy club 272/272, been now 5 yrs, upgrade spring and retainer to be the safe side

 

I was running 8500 rpm, with BC valvesprings and retainers, and Cossie M2's on a 9 MR and I missed all kinds of shifts!
