Im curious to know what caused your bearing failure.

Re: Budget Z6 made 309.9/250. Xenocron Tuned.
 

RPM, heat, thin oil and low pressure.

How high were you revving the z6 head? I remember you said 8400 rpm with the y7 head...

in for the updates. vitara builds excite me. i have one in the works right now

Re: Budget Z6 made 309.9/250. Xenocron Tuned.
 

About the same rpm.

No need to go higher at this point without retarding cam timing.

What about the rods that you had used? Were they checked to be within specs?

Re: Budget Z6 made 309.9/250. Xenocron Tuned.
 

They were brand new.

Its really not a big deal, things like this happen all the time.

Re: Budget Z6 made 309.9/250. Xenocron Tuned.
