Description

300hp+ On a STOCK Engine?? Yes please!

QG Engine Swap Mounting Kit. This kit will work with QG15DE (1.5L), QG16DE (1.6L) & QG18DE (1.8L) Engines.

Developed as part of our Time Attack program, these mounting kits will allow you to bolt in a QG Engine From the later Nissan Almera/ Primera chassis without any cutting or welding of the chassis to move the mounting locations. This engine mount kit uses the K11’s existing mounting points.

The QG Series is Nissans revision of the once popular GA16DE Engine. It has a revised cooling system and overall revised engine block – in our eyes superior to the GA16.

The Kit

• The kits consists of 3 Mounts including the timing side engine mount, engine mounting bracket and the front torque mount.
• All the mounts are poly bushed.
• powder coated and supplied with hardware.
• This kit re-uses the OEM Rear engine mount and OEM Transmission Mount.

The Types of QG Engine

• There are 3 capacity sizes. QG15DE (1.5L), QG16DE (1.6L) & QG18DE (1.8L)
• The QG16DE is Mainland European Market Only.
• The QG15DE & QG18DE are the common sizes found in the UK.
• There are 2 Types of QG Engine, Silver Top & Black Top

Silver Top

• Aluminium Engine Cover
• VVT Solenoid In the Engine Cover
• Tubular Inlet Manifold
• Electronic Throttle Body.

Black Top

• Plastic Engine Cover with Bulge
• VVT Solenoid On rear of cylinder head
• Cast Aluminium Inlet Manifold
• Cable Throttle Body.

Water Pump, Crank Pulley and Clearancing 

Just like the old GA16 Swaps, because the engine is physically longer, you will need to consider the following for the water pump

• Notch the chassis leg to clear both the water pump pulley and lower crank pulley in order to run the OEM type Belt driven pump
• or opt to use an electric water pump & trim the outer section of the pulley meaning no cutting of the chassis leg is required.
  • We can provide you with a Billet Water pump cover, message us for details.
• For RHD Models, the inlet manifold may be a clearance issue for the Brake Master cylinder depending on the type of inlet you have

Transmission

The whole point of this kit was to make the easiest engine conversion possible in terms of mounting the physical engine.

• Factory K11 Transmission – which means you can also retain the Drive shafts, clutch operation & gear linkage.
  • It is understood you require a later coil pack type flywheel and clutch.
• QG15DE/QG16DE Transmission – You will need to use a Later K11 Micra Coil pack OEM transmission mount. This transmission is Hydraulic Clutch (Compared to K11 Cable)
  • Retains QG15/Qg16DE Flywheel & Clutch.
  • Will require to either convert the transmission to Cable Clutch, swapping components from the K11 Transmission
  • Or, convert the clutch pedal to Hydraulic using P12 Primera Pedal & Master cylinder (The pedal mostly bolts in with some trimming, Master cylinder is direct fit in place of cable guide in the firewall)
  • Slightly stronger transmission compared to K11 Micra.
  • Requires the gear linkage to be extended.
  • Custom Drive Shafts Required (We cannot supply)
• QG18DE Transmission – You will need to use a Later K11 Micra Coil pack OEM transmission mount.
  • “70A” Gearbox. This transmission is easily spotted due to a removable plate on the front of the casing with 6 bolts.
  • This gearbox shares the same gearset as SR20 FWD Transmissions, Such as Almera GTi.
  • This gearbox is considered much stronger than the K11 Transmission and is better suitable for high power builds.
  • Using the QG18DE Flywheel, allows you to use SR20 Clutches.
  • Will require to either convert the transmission to Cable Clutch, swapping components from the K11 Transmission
  • Or, convert the clutch pedal to Hydraulic using P12 Primera Pedal & Master cylinder (The pedal mostly bolts in with some trimming, Master cylinder is direct fit in place of cable guide in the firewall)
  • Requires the gear linkage to be extended.
  • Custom Drive Shafts Required (We can supply)

Engine Upgrades

• The QG15DE and QG16DE use the same cylinder head designed for the 75mm Bore of the QG16DE
• The QG18DE cylinder head uses the same overall cylinder head design, with the exception the combustion chamber is suited for the larger 80mm Bore.
• Performance Camshafts do not exist, However Qg18DE can be considered a upgrade for the QG15DE and QG16DE with there slightly longer lift and duration.
• The QG15DE uses a 73.5mm Bore and the Qg16DE Uses a 75mm Bore. From our testing – you can use Honda D16 Pistons (Come in a range of sizes from 75mm).
  • Our testing saw us using Forged Honda Vitara Pistons with a 75mm Bore with the engine block machined.
• The QG18DE uses an 80mm Bore. Its from our understanding that Z16LER (Vauxhall/ Opel) Pistons could be used. We are expecting to confirm that later this year (2024)
• All 3 Engine Sizes use the same crank and stroke (88mm)
• Forged Rods are available, GA16 Rods are the same.
• Whilst all variants of the QG Series has VVT, it does not work like Honda VTEC. Rather it engages to promote low-range torque for town driving (Rather than engage for high RPM Performance)
  • We tested the VVT on the dyno and it does not pose any performance benefit.
• USDM Market KA24DE ARP Head bolts are a direct fit.
• The QG Series uses a Steel, MLS Head gasket as Factory.

From our testing. We saw 280hp on the QG15DE stock Engine & 320hp on the Stock QG18DE Engine!

The weak point at these power levels is the stock OEM cylinder head bolts. We saw at 280hp & 320hp respectively, the cylinder head lifting. Consider upgrading the head bolts at these limits.

Wiring and ECU

It goes without saying that the factory K11 Wiring and ECU will not run this engine. You will either need to produce a custom engine loom & ECU or modify the QG Engine loom & ECU to make this engine run.

Considerations

As with any engine conversion, there may be issues you will face not covered in this extensive FAQ. So please enter this engine conversion with due diligence that there may be some additional work not covered here.
