From Datsun 1200 Wiki

E15 (http://datsun1200.com/modules/newbb/viewtopic.php?topic_id=6054&forum=1), E15ET (turbo) or E16 OHC, crossflow engines is an interseting engine swap These are plentiful in mid-80s Pulsars and Sentras, are similar to the A15 and have plenty of go-fast parts available. The E-series was a re-design of the A-series engine with the same bore spacing and other critical measurements, but tailored for front-wheel drive installation. A-series transmissions do bolt to the block but the starter location is different. Some question whether a stock E15 has any real advantage over an A15, but there is no question that the E15ET is a superior design.

Swap Notes

• Distributor is in back of engine, which will the Datsun 1200 firewall. Remove and use a crank-trigger system like EDIS.
• Starter?
• Transmission bolts up and matches the locating dowls, although two holes on each side don't match. Use a modified A-series engine plate.

E15ET

Turbo Power! Right from the factory. Some question whether a stock E15 has any real advantage over an A15, but there is no question that the E15ET is a superior design. The cylinder head flows more than other E-series engines.
