so i have a ls vtec with a stock b18b bottom end and a b16 head with GSR camsand a B16 tranny i was wondering how high i could rev the stock LS bottom to without messing anything up i have a ecu with a 8500 rev limiter i have only been takin it to 7200 but i was wondering if 8k would be safe on stock rods and bearings i have a type r oil and water pump also on the car thanks for the help

 

i rev my **** to 8200-8300 daily for like 7 or 9 months now n no problms yet *knocks on wood* and i currently have a completely stock b18b bottow with a gsr head n cams on a ericks ECU... oh and im on a ls water and oil pump

I have been revving to 7500 for nearly a year now without problems, i just dont trust it anymore than that. If you are going to rev it to 8+ the least you can do is make sure you always keep up on oil changes ect. but its likely that your rod bolts will take a dive over time.

 

Keeping your oil in check doesn't mean anything as far as rod bolt stretch.

Rev that high, and those suckers WILL stretch and you WILL spin a bearing. Give it time.

You said it yourself already. "Luck of the draw"... so why need someone else's explaination?

Give or take the trans options given to all and to see where they make most power at will give there shirft points. Now this kid never mentioned power ( didn't read all just skimmed) but you can rev a motor as high as you want all day? did you remember about everything else that can blow? maybe a oil pump can fail and you could be just driving home when that happens. a valve drop just cause your luck of the draw just did happen to run out.

You dont have high compression or should have a issue. There is no need to rev that motor to 9100 rpm like I used to ( your setup is way different like mine is so different then others ) Your safe, just tune it and make adjustments to it within your budget Good luck to you bro and have fun first of all.
