what are you guys taking the revs to on the stock bottom end? and how high can i go before i spin a bearing? right now my rev limiter is set at 7400rpm

 

problem is the top not the bottom....
what cams?

 

...oh, sorry... here's my setup:

b18b obd1

Act stage 4 clutch, pressure plate, and release bearing
AEM Cold air intake
AEM fuel rail
AEM tru time pulleys
B&M fuel pressure regulater, with gauge
Crower stage 1 cams
Golden eagle adjustable cam gears
GSR DC Sports 4 2 1 one piece header
GSR Cat, and DC Sports Cat back exhaust
GSR obd2 injectors
GSR transmission Phantom Grip LSD with LS 5th gear
Hondata intake gasket
Mr. Gasket distributor cap and rotor button
Nopi brand - lightweight flywheel
Performance chip tuned by crome
Prothane engine mount bushings
Skunk 2 intake manifold
Unorthadox Crank pulley

 

hmm i wouldn't go past 7400... i wouldn't even go past 7200... on a ls... change the oil pump and you'll be safe...

 

change ur rod bolts too............

 

ahh got me there brah.. lol ARP is the way to go!!

 

changing the rod bolts entitles pretty much for a whole rebuild.... its not just change them and go...there is machining involved wich needs the rod to be out of the engine..
I think you can go safely to 7500- 7800 on stock bolts.
Waterpump also cavitates after like 7400 rpms.

i see no aftermarket valvesprings.. i would not rev higher than like 7200-7300. you are already putting way more stress on the springs by using aftermarket cams.
Stock springs are weak for stock cams..just my opinion

 

rod/stroke ratio FTW!

Ignore the ls/vtec part, and read the part about r/s ratios.

check the difference between the b18c and b18b R/S, not much of a difference to really worry about unless very high rpms.

well the main reason you cant rev that high is 1.your head .2.b18a or b does not have the oil squirters supplying oil to the sleeves when the piston is going up and 3.no vtec girdle..so I say no more than 7400

the non vtec motor has its own piston squirt lubricating system, through the rod pin hole.
Oil squirters are a neat thing, but not completely nessesary.
the girdle is pretty much only needed if you do lots of high speed highway runs.

Im in no way saying that all those things do do crap, what im saying is that for years and years now, including me, people have been revving their ls block to vtec rev limits with no problems.
rod bolts are the weak link if anything.

 

mmuller in for the kill... ( i sure as hell rev'd the crap out of my ls block when i had it 9k everyday! )
