Gday Uriah, got a 35 + with about 12litres threw it now, been running like a champ, absolutely love it. Today the rod let go on me, was running a bit rich sitting around 220 was running good, then lost a bit of power pulled in, leaned a bit another run then bang, just shut down game over, snapped in the middle and destroyed the brass bush and the rod. I know its a bit hard to say without seeing, but what are the causes for this type of failure, I am definitely the first cause. any help would be appreciated, Ill try and get a couple of pics up for you.
cheers Burty.
Forgot to add,i replaced the rod at 8 litres, should have done it sooner maybe???
cheers again.

Cheers Stefan, lesson learnt the hard way lol. thought it might have been my tuning, but it always ran brilliant, damnit, I knew I should have replaced it sooner, I am a tool. it was always in the back of my mind that the I should have done it sooner.
Ill definitely be getting another murnan anyway, was a sweet motor.

Im sorry to see that. Hard to say what caused the failure. It could be a faulty rod, fuel. I replace the rods in the 35+21 each 4 liters if I'm pushing the engine.

Gday again Uriah, thanks heaps for all the help, I'm going to get another one of your motors and I was pretty set on getting another 35 +,but im torn between it and your M21 , tracks tight and short, M21 work well with nova 2015 and med header? What plugs for the M21? I've got a few c8tgh novas, but if I get the m21 would also like to get picco plugs.

What model RB is this? I can't find what it is and it's not on your website. The motor is supposedly brand new and is coming with the 2012 nt1 I just bought. He says there's less than a gallon thru it and IMO its not fully broken in if that's the truth. I paid $100 for it not including the car, did I get a good deal?
