Fund Raiser AB blew his engine

[Sir Roofy]

Ahhh so the 4.2s arnt bomb proof
seems like the older ones could be
like the 3lts of the same vintage
you just never know till you
start researching and gets
more intriguing as you dig
deeper

The blacktop is still a strong engine. Benny pushed on his pretty hard and I don't think it ever gave him troubles?

[AB]

Nah, nothing at all wrong with the NA black top at all Roofy, very reliable engine.

@Sir Roofy, nah all good mate, the TD42 is a Solid Engine, solid platform. Silver Top or Black top they are tough as guts.......... They are tuned to 65rwkw out of the factory. The TD42Ti is about 70rwkw and 9psi of boost. With just a Dyno run i have mine tuned to about 92rwkw and 15psi and its done 200,000kms there. good for another 500,000kms there too.

If you look around Facebook you will fine all this chatter about "Kettles" and snapping Cranks. Now we are talking about guys pushing 150rwkw and above or badly tuned, there is a big group of young guys chasing big numbers beyond 200rwkw that are snapping cranks. AB had 200rwkw and a bloody strong engine. if the cause was hydraulic lock from trapped oil then it would have happened at 100rwkw too.

Unfortunately the ZD has a reputation of going bang regardless of its treatment. Don't worry Toyota has exactly the same bloody problem but no-one is talking about it like the ZD.

For a Farm Tractor engine the TD42 is a Beast mate.

I have heard though that you shouldn't push a black top NA engine over 15 psi.

This was a between era of a dedicated NA engine and the Pistons and conrods whilst are still strong are somewhat lightened for a dedicated roll out non turbo.

Happy to be questioned on this though?

The pistons were lighter that was about it. Cranks seem to be the same and apart from little end differences rods arent any weaker. I put one together that ran 23psi and just over 200rwhp. it has done about 30,000km without issue.
