Can anyone confirm that the internals of a 1994 silver top are the same as an 88-93?
I might of found something but its out of a 94, It's silver top and I heard stories of mixed internals on a 94 and 95 models.
Can anyone help me???
Ooh, can't help but hope it's all good. . .
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?
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?
There are 28mm and 30mm gudgeon pins. So obviously the little end (piston end) will be different. This seems to be more of a disassemble to know. Although I think the silvertop maye have 28mm gudgeons and the blacktop and NA have 30mm gudgeons. Ben-e did note some of this is in his engine build thread Im pretty sure.
Good little read here ab

The easiest was to tell a true silvertop block (if it is dismantled obviously) the ports for the lifters. Silvertops have 25mm lifters, NA blacktop and T have 27mm.
My 96 blacktop had the 30mm gudgeons. The sludged pre Aug 95 blacktop I was offered for replacement of my POS pile of scrap was a silvertop with a black rocker cover. 28mm pins, 25mm lifters.
The article above saying black tops are unsuitable for turboing is nothing but an opinion based on a guess.
Yes. I did crack 3 pistons, 2,4 and 6. All originating from the centre of the swirl chamber, cracking perpendicular to the gudgeon pin. I cannot see the cracks on the under side of the crown. I haven't done a proper crack check though and likely wont. I'll add that I was turning a 30 psi boost gauge pretty much back around to zero,
I didn't strip the motor because of the cracked pistons, it was always going to happen. I just was not surprised when I found them.
Might have found something folks!!!
I'll let you know tomorrow!
Excitement!
Fingers crossed for you AB
