Nismo S-tune S1 engine is a nismo engine , yes its something special, its better than your stock nissan one. nismo made S-tunes for each model. You will notice the middle one is the nismo 400r which possibly utilized a Tuned version of the S-tune engine :) can anyone confirm?

I've seen some GTRs with S1 engines, according to Nismo they have around 400ps which is not all that significant compared to what one can do to increase power. Are they overrated or something special?

I see you're comparing the S1 engine to something alot more 'unstreetable'... are you asking because of the low bang for buck value it seems to have on paper?

The S1 engine are for increased power and torque across the rev range, giving a useable boost in those areas with less stress on the engine. It's a 'street performance upgrade' for GT-Rs (and others) and outright power is not the main focus. Think of it as a higher power RB engine from the Nissan factory, with all the reliability that goes along with it.

Thats not a 400R.

The 400R has a REINIK 2.8 litre engine called RB-X GT2 (N1 block with forged internals etc etc) 400bhp 478nm lazy

S1 is a rebuilt engine with N1 parts has 400bhp 450nm by nismo

R1 is a N1 block with N1 parts has 450bhp 480nm by nismo

F-Sport is a 2.8L engine with GT block and mostly Gt parts like the Z-tune not sure of the power

hope that helps

ps saw a N1 block (new) on Japanese yahoo for A$1400 GT block was A$4500 new on yahoo nice start

      I'm going to slap an old nismo logo sticker on my spare one and sell it to the land of the free for a thousand bucks

      Well - they have arrived.  And they are easy on the eye to put it mildly... These only have three bolts - but for a start there is a key that fits with vacuum like precision..  And as you can see by my ruler, the interface is large..   I listened to a podcast on HP Academy about Dan (KiwiCNC) and I'm more than comfortable he knows what he is doing. R35 Bearing assembly should arrive later today so can mock that up for a look. Can't wait to get these on and get some brake pressure logging too. IMG_3860.MP4

      I would be very confident that they are the same parts (the 2 different SKUs). It seems very clear that you can drop the cam in the 2-way opening, or in the other opening. If you arrange it in the other opening in the same way that you see any other 1-way diff, ie, with the flat of the cam up against the 1° side of the opening, then it would work as a 1-way. It can only spread the ramps when driving forwards - cannot spread the ramps on overrun. It would then appear obvious that if you put the cam into the opening "backwards", that you would get the angled flats of the cam working onto the "points" of the 1° side of the opening, which would give you ramp spread in both loading directions. I do wonder if the forward direction of the 1.5-way config is equivalent to the forward direction of the 2-way, seeing as the cams are flipped and the angled surfaces on those would need to be the same on each side - AND - clearly when installed in either the 2-way or 1-1ay configuration they are not intended to work exactly the same (the ramp angles on the 2-way are 10° different between forward and backward, and the ramp doesn't exist in the 1-way config). 'twere me, I think I would rather actually have a set of rings that offered the 2-way with two different sets of ramp angles, say the 55/45 of the existing design and maybe a 45/37.5 combo for a less aggressive effect), AND another set of rings with a dedicated 1.5-way opening and a dedicated 1-way opening. The 1.5-way opening would actually have the steeper angle on the overdrive side that causes it to be less pushy than the forward drive angle, like you see in many other diffs. But really - if this Nismo thing is thought out properly and all those surfaces work on each other the way that they need to, who am I to argue?
