		+	The {{wikiEx|Nissan GA engine|Nissan GA16 engine}} is similar to the A15, but has the distributor in the back. This is a high-output lightweight engine, the GA16DE version has 16V head and variable camshaft technology making 115 hp. RWD transmissions are available in Asia and Europe markets. It is also possible to adapt a [[60-series Transmission]] from a Datsun [[B210]] or [[B310]] as well. There are also GA13 and GA14 engines but it's not really worth all the work for the smaller displacement. A GA18 is perenially discussed, but appears to be a global legend, always existing in some other country but never actually seen. The GA engine series was replaced by the QG series in 1999 (the QG18DE has 126 HP).

The compelling part of this swap is 116 HP from variable cam timing. You could even carburete this engine and still use the VCT with an RPM-activated 12V relay.

<-- back to Engine Swaps

The Nissan GA16 engineᵂ is similar to the A15, but has the distributor in the back. This is a high-output lightweight engine, the GA16DE version has 16V head and variable camshaft technology making 115 hp. RWD transmissions are available in Asia and Europe markets. It is also possible to adapt a 60-series Transmission from a Datsun B210 or B310 as well. There are also GA13 and GA14 engines but it's not really worth all the work for the smaller displacement. A GA18 is perenially discussed, but appears to be a global legend, always existing in some other country but never actually seen. The GA engine series was replaced by the QG series in 1999 (the QG18DE has 126 HP).

Overview

The Nissan GA16 engine is similar to the A15, but distributor is in the back and RWD transmissions are available and Asia and Europe markets. The compelling part of this swap is 116 HP from variable cam timing. You could even carburete this engine and still use the VCT with an RPM-activated 12V relay.

Transmission

A-series Transmission

GA engines may use the E-series bellhousing pattern — reportedly it shares enough bolt and alignment pin holes with the A-series for the transmissions to line up. Just like the E15, the block dowels line right up.

Use an A-series gearbox. Three block-to-transmission bolts line up. The input shaft may need to be machined as it is a little too long for the GA16DE.

Or, use any 4-speed or 5-speed you want. Use the traditional method of an aluminum adapter plate that bolts to the engine and provides new holes for the transmission and starter.

• bolt up 3 bolts
• redrill 4th bolt
• machine GA flywheel to accept A12/A14/A15 flywheel ring gear
• grind GA block corner where A-series starter fits
• Cut extra length off the A-series spigot (or drill the GA crank deeper)

GA uses B22 pilot bushing, as fitted to many Datsun engines

GA RWD Transmission

Or in Europe or Asia, source a Serena GA RWD transmission (Nissan Van C23 1992-). They have these in Japan, Malaysia and New Zealand too.

This is a large 71-series transmission, so tunnel mods will be required. Possibly could be converted to floor shift using Z-car or Silvia rear housings. However, the shifter will be too far back.

Swap Notes

Use a manual transmission GA engine flywheel. If using a 60 series B210/B310 transmission: remove the GA starter ring gear [it's facing the wrong way for the FWD starters anyway]. Use the [smaller] A series starter ring gear and machine the back of GA flywheel to fit it [it's an interference fit]. Then heat the A-series ring gear and install it backwards from the original GA gear. You can notch the GA block for clearance and use the stock A-series starter.

Remove EGR and block, since it points backwards.

Remove distributor and fit an inexpensive EDIS crank trigger system (about $200 USD). Or simply cut an access panel in your firewall for clearance and use the original distributor.

Weld up new motor mount brackets -- typical engine swap stuff. This is not a bolt-in swap.

Fit a carburetor (custom manifold) OR use the factory EFI and ECU (convert your 1200 to EFI):

EFI fuel pump
Surge tank
Fuel lines
Return line to fuel tank

On a GA16DE the standard throttle valve will be against the firewall. Either relocate it with a custom intake, cut out the firewall to allow intake piping, or use twin side draft carbs.
