The SR18DE, AFAIK, was only availabe as a base, 126-130hp engine. It was dropped when Nissan developed the QG-series... (seriously off topic).
Back on topic. There was a 195 hp SR16VE in the N1 pulsar. Badass engine. Our local Nissan actually had one lying at the dealership here a while back, as they were planning to use it in a Sentra touring car, but they never got the budget for the project. This was a boxed engine and they were offering it for sale. If I hadn't sold my SR20 Sentra, I would've bought it.
This is a factory car engine mind you, sold in a straight from the dealership car. Was hella expensive to produce, very expensive to buy, but the Honda Type R still pwned it on the track.
There are also the various 170++ hp B16 Hondas here and there...
But if we're talking modern engines, Nissan doesn't use the SR16 anymore, just various SR20Ms, VEs and VETs.
I think the John Cooper S Works counts as factory, doesn't it?
