Does anyone know how much RPM's a stock GSR block is good up to? It has low milage too.

 

stock redline

 

i believe the stock b18c1 redlines at 8200 rpm

 

I will quote hondahookup


But why?

 

8k duh..

 

Stock bottom end, stock valvetrain, stock camshafts = stock redline

b18c1 stock redline is set to 8000 rpm you rev too far over that and you'll lean out and say bye to your motor. The stock redline is there to make use of your stock powerband and keep parts intact. You really don't need to rev over it until you modify your powerband via tuning, cams, etc.

 

8200 RPM

haha say bye to your motor? i doubt it. if you go up to maybe 8500 its ok, your not gon' blow anything, but yeah you wont make any power up there with stock cams and stock block, might as well stay close to the redline as possible

 

no i have a fully built head, it can rev to 9,xxx ish safely... just wondering how far i can push the block.

 

you can push it according to how good your engine is built, ie valvetrain, block, pistons, etc.

Only way to know it to take it to 9k rpm, if the block blows, then you'll know that that was the limit of THAT motor and that motor only. My cousin used to rev his stock block with a built head to 8500 rpm daily for a few years, never had a problem. Then he rebuilt the bottom end with all forged internals, now he revs to 9200 rpm daily.

 

u can push it up to 11k but why would u risk a low millage engine and plus ur loosing power after 8k arp

I meant he'd be running the risk of causing detonation due to a lean air/fuel mixture. That's why I said "if he revs too far" meaning: Past the fuel cut point.

Don't go past 8500RPM MAX.
