i spoke with my nissan guru mate and turns out he's the guy who may have been the original source of d's info about the terrible rod/stroke ratio of the qr25

his estimation is that the qr was originally designed by nissan engineers to be a 2.0, but marketing demanded a torquey 2.5 to please the smiths

so they cobbled it together, much the same way guys put z24 cranks in l20b's and thought there was no replacement for displacement

I was more worried about the fact the water inlet and outlet was at the back of engine. Z20 flywheel should match up with the crank . After having a looker at an S15 gearbox it looks to close to call so I will need to line them up together. Will do what I can with my limited funds I have for the time being. Throwing alot of money at my 240C daily ATM.

yeah but look where that top water aoutlet pipe juts out... should be able to be worked around easy enough

A serviceable location for an oil filter...wow!!!

Looks like a normal engine after all the plastic and pipes are removed.

Good Luck with the project.

The QR less intake manifold and 'box.



And from the exhaust side.

Seem you can use the gearbox bellhousing to adapt to either a nissan or toyota box for a RWD setup.
Good buy. These engines are the best with the big bore and short stroke. 200hp should be easily attainable with some freeflowing exhaust, lighter flywheel, twin balancer shaft removal and custom ecu.

Good on ya. Yes, use the gearbox that comes with it. It has a yoke I suppose you could count the splines.

The wireless throttle should be easy -- no cables to run. Just a couple of wires. Use the pedal from the truck?

If I had time, this is what I'd fit to my 1200. The QR engine now has lots of parts available, lightened flywheels, cams, etc. But I would keep it all stock. Stock computer, wiring, etc.

More spam kinda. Just bought that engine.

I found out 110kgs for the engine haven't found out anything about the gearbox weight.

Anyone have an idea of complete engine + factory X-trail gearbox weight?
