Nissan GA16 engine. Engine is similar to the A15, but distributor is in the back and only has fwd transmissions. This is a high output lightweight engine, some with 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.

Sources

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.

Sentra B13

1991-1994
110 hp 

USA Sentra B14 XE and GXE

1995-1999
GA16DE 1,597cc DOHC 
7,200 rpm redline 
115 hp (86 kW) @ 6000rpm 
110 ft lb @ 4500 rpm

USA Sentra 1999 specs

Look for the Bulge on left, which indicates NVCS variable-valve timing (115hp)

Transmission

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.

The 63A 5-speed input shaft will have to be machined.


Or in Europe or Aisia, source a Serena (Nissan Van C23 1992-) RWD transmission.

  • 32010-G2N69 RS5W71C [remote shift 5-speed 71-series transmission]
    • Europe
  • 32010-0C061 RS5W71C
    • 9106-9701 Japan
    • through 2009 Malaysia

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 convert your 1200 to EFI:

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

Oil Pan?

New exhaust pipe and use 1.75 piping and muffler and tail pipe
