Nissan GA16 engine. he Nissan GA16 engine is similar to the A15, but distributor is in the back and RWD transmissions are avialable and Asia and Europe markets. This is a high output lightweight engine, the GA16DE version has 16V head and variable camshaft technology. There are also GA13 and GA14 but it's not really worth all the work for these smaller versions. 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).

GA16 is fitted to FWD Nissans like Sunny/Sentra and Pulsar circa 1989-2000. Also to Tsubame Y10 (Mexico) through 2004 Tsuru B13 through 2007.

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, and so do three block-to-transmission bolts. The 63A 5-speed input shaft may need to be machined as it is a little too long for the GA16DE.
Use any 4-speed or 5-speed you want. Use the traditional method of using an aluminum adapter plate that bolts to the engine and provides new holes for the transmission and starter.
Or in Europe or Aisia, source a Serena (Nissan Van C23 1992-) RWD transmission. They have these in Japan, Malaysia and New Zealand too.
- 32010-G2N69 RS5W71C [remote shift 5-speed 71-series transmission]
- Europe
- 32010-0C061 RS5W71C
- 9106-9701 Japan
- through 2009 Malaysia
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. Instead, consider the stock Remote Shift version, with a floor shifter from another car adapted (remote shifter).
Swap Notes
Use a manual transmission GA engine flywheel, heat the ring gear and tap it off. Put it on backwards.
Remove EGR and block, since it points backwards.
Remove distributor and fit an inexpensive EDIS crank trigger system (about $200 USD).
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
Weber DCOE twin-carburetor manifold
Oil Pan?
New exhaust pipe and use 1.75 piping and muffler and tail pipe
Variable Cam Timing
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.
