What Is An S1 Engine?

[Informer]

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?

The only GTR i know of with above 206kw from factory is the R33 400R

This is the S1 engine. Just wondering what's so special about it.

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 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
