Swapping a wikipedia:Nissan CA engine into a Datsun 1200 is perhaps the most common swap. It provides abundant horsepower (up to 400 hp) in a small, lightweight package. The CA18DE is a dual overhead cam engine, while the CA18DET if a factory turbo engine. It will fit into the 1200 without cutting the firewall or body. You will additionally need a stronger rear axle assembly to cope with the extra torque that the CA-series puts out.
For information on choosing a rear axle, see Rear Axle Swaps.

See:
Choose a CA engine
- CA16DE (Only available in FWD format)
- CA18DE
- CA18DET
- CA20 (Not a performance engine)
Choose a Transmission
Stumpy Transmission
The "stumpy" transmission bolts right into the 1200, and the gearshift lever comes up in the right place. Other CA transmissions will require you to cut a new hole in the tunnel farther back.
See:
S13 Silvia/180SX Transmission
- Manual tunnel needs pretty much all of tunnel replaced from 120Y, or 1200 Automatic tunnel. - Most will need a box section cut into the shifter area to clear the shifter area on the gearbox.
== Series 3 Bluebird (910) CA20E/CA20 5 Speed - This is a straight fit, and for low power applications this is a cheap alternative. Especially if you can find a low milage example.
Fuel Line, Pumps and Tank
Use high flow rated Bosch EFI pumps, Walbro pumps (watch out for the Ebay fakes).
Upgrading the CA engine
Injectors
Injector changes almost certain require a tune change, which needs either an aftermarket ECU, or a chip to be modified/burned and inserted into a modified factory ECU.
General recommendations for high powered CA18s require 440cc to 700c injectors to be used.
Turbo Choice
Sensible Street -> T28G, GT28 (s15 jdm), GT2810 -> GT2835. Drag Racing -> GT2840, Various large T3, HKS, Trust or GReddy offerrings.
Camshafts
Tomei offer: Hydraulic -> 256 deg to 270 deg duration at a nominal lift of 8.8mm Solid -> 264deg to 270 deg duration with 9.25 or 10.25 lift. Requires solid lifters and shims.
HKS: All discontinued, and no longer available new.
