Take a look at this thread.

There is a photo of a newspaper article on the changes Nissan made to the T version of the SD33. It states that the camshaft journals were enlarged - although I can't see why they did that ! Maybe there was some other problem Nissan fixed when they did the SD33T

So, in answer to your q, based on this, yes there is a difference.

It means engine block's are different :roll:

I was hoping to find some info abouth cam lobe differences (Some non turbo engines intake and exhaust valves are open longet time or larger then turbo versions)
In the manuals is that the cam hight for limit when checking them is for the sd33 and the sd33t both 36,8mm

There are three different ordering codes =
'79-'83 SD33 = 13001-90109 & 13001-90111
'83-... SD33 & SD33T = 13001-C8600
seems - some are same - some are different :roll:
