Just a lil extra info.





I found out more info on the Series 2 QGs (CVTC- E-THROTTLE).

CVTC advanced and retard timing depending on driving conditions. VTC only ADVANCE to improve torque at low to mid range.

EDIT: CVTC plunger (valve) can shift direction of oil, hence, it can retard timing or advance it, and it seems VTC plunger cannot, only in one direction (advance)....There are no detailed information on VTC in service manual, but CVTC is nicely explained...

CVTC retards timing at high speeds to increase power from mid range to high end.

CVTC equipped QGs has an alumium valve cover vs the VTC black plastic top.

CVTC also came without EGR (exhaust gas recirculation)

The series 1 has a different lower intake plenum, with this thing nissan calls a "swirl control valve" that stays partially closed at low RPM to increase torque, and dissengages at WOT. It was disconinued for the series 2.


QG's are lean burn ENGINES...it uses a bit of extra air to improve performance at early rpm


The solenoid valve controls swirl control valve’s shut/open condition. This solenoid valve is operated by the ECM.

I'm quite proud of the low maint, fuel economic, QG18.

Nice engine. Not a very tuneable one, but real sturdy.

Check out this link ppl, a QG18DET in Australia competing in race events.

[azis]

i have a local almera with a qg16 very good on gas to mileage
and i drives well. it only doing 20,000k's tho

[RadDogJr]

Gots a manual QG16. Mad as hell & I love it!!!!!!!!!. Fuel consumption is boss

[sufferrar]

Ah posting for me wife since she have the 2004 wingroad QG15de.

[formula_1]

QG 16 - reliable and low on fuel consumption , considering our traffic conditions and the amount of time spent in a stationary vehicle

[QG]

Good, good i know there are proud QG drivers out there...here's an advice that you all should take; buy the PETROL PLUS injector and gas cleaner at LAUGHLINS & DE GANNES for only $25 and u will see greater improvements on the gas mileage.

[juicy_j]

QG for life

[Trini_tech]

Have A QG15 in my nissan AD

[Reyos]

You do ah engine swap or what? Tranny or gears?

Bought the car just so......is a Tranny...4WD is the way to go yes
I will try that "Petrol Plus" thing and get back to you on its performace ....
I have to make some time to service that car yes..it real burning gas lately......
BTW...someone tell me that if i looking for new parts for the 4WD AD i would not get it because no one bringing it in....anyone know if that true ....

[azis]

well even if you cant get it outside just walk with ur chasis # and go neal and massy or motorist

[achillies]

qg15 in a b15

good gas mileage and i run ac all the time

no problems at all

[QG]

Well Quicksilver, you will get parts for the 4WD AD but you'll have to alot of asking around. Or if you know south good, go to DIAZ ENTERPRIZE in Duncan Village; opposite the LEN HAP Grocery and i'm sure you'll get yuh parts ...if not simply go to Neal and Massy like Azis said.

[QG]

I read that a QG18 comes with 4 O2 Sensors, do you all know if the other sizes of QG comes with 4 or just one?

[RBphoto]

Here is a another idea, get your injectors and throttle body cleaned twice a year and use premium gas. Proud QG18 owner here. My mechanic tell me doh use de cleaners, but I still put one in about a month before is time to do a tune up.

[Strugglerzinc]

for a moment i thought you meant QG18 in the Tiida ^^^

Nissan QG15DE, you can do what azis say. You would be surprised.

[quote="Strugglerzinc"]for a moment i thought you meant QG18 in the Tiida ^^^

QG will not fit in a Tiida. the HR and MR engines specially made for that small engine compartment to boost interior space and legroom. Because of the pushing forward of the firewall, the Tiida has more legroom than a Cifero.

D QG18DE in my bluebird. It has 1 O2 sensor after the cat and headder. The california model sentra have 4, on the headder before the cat on each pipe I think. For emission regulations I guess. The american sentra shop manual for the QG18/ QR25 is downloadable on the net. Worked well for my car.

Mr QG15,
You had that headder made or aftermarket? What did you do with your O2 sensor and emmisions control? Also, think you should put some insulation on that (Lagging)
