Anyone With Experience With Bisi Regrind Cams

[hotrodj]

Looking for any insight as to performance or probs with the Bisi regrinds. Thanks

make sure you get new valve spring or you'll end up with valve float......dont ask how i know

Lol I think I might have figured out what happened already lol I run a Bisi cam and springs on my D16. But its not a regrind, just wondered about the reliability/longevity of the regrind.

I used a bisi regrind dorm about 20 miles until a valve face snapped off and destroyed my engine. Everything from bisi held up fine though.

This is what can happen when you try bolting a higher lift cam and new springs on old tired valves. If you are looking at using a cam that requires the use of a new valve train, remember that valve train includes valves as well. becuase when a valve goes, it's not the fancy new valve train that suffers, it's the head, piston and possibly the cylinder!

Oh it went beyond the head, piston, and cylinder... The block somehow managed to develope a crack about an inch and a half long inside the water jacket. If money and time permitted i would of gladly bought new valves but i had to get the car running and out of my brothers old garage. That's about all the more i got accomplished. Had to tow it the last 3 blocks.

Just to share a little information about Honda camshaft and Bisimoto regrinds. Factory Honda camshafts undergo a heat treat process that penetrates far beyond what is ground off during Bisimoto regrind services leaving the camshaft factory integrity and reliability with a good bump in power. Along with Bisimoto camshaft profiles it is recommend to invest on Bisimoto Pro springs to replace factory worn springs and gain the proper seat pressures to overcome valve float.

I'm sorry to hear about your experience. If you are in need of assistance with a Bisimoto performance valves, and other components don't hesitate to shoot me a PM. I will gladly help you get your project back on the road stronger and faster then ever!
