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.

The extra valves make it breathe very, very well which mean a lot more HP. All CA Double Overhead Cam (DOHC) engines have 4 valves per cylinder -- it's worth seeking out over the older SOHC versions.
-	= Choose a Transmission =	+	* 2-valve CA18E 113 hp
-	* CA16 uses a smaller clutch & gearbox. E16 & GA16 use a different bell, but same transmission series	+	* 4-valve CA18DE 131 hp
-	* CA18 & CA20 use a factory adapter plate & larger tranmission	+
-	NOTE: RWD & FWD blocks are the same.	+	4-valve:
		+	* CA16DE 122 hp
		+	* CA18DE 131 hp
		+	* CA18DET 167 hp turbo
		+	2-valve
		+	* CA16S 80 hp
		+	* CA16I
		+	* CA18S 90hp (Single carb)
		+	* CA18I 91 hp (single point EFI)
		+	* CA18P (LPG)
		+	* CA18E 113 hp (EGI/port injection) 113 hp
		+	* CA18ET 135 hp
		+	* CA20S 102 hp
		+	* CA20E 105 hp
-	You can use the typical CA18 gearbox. It is longer than a Datsun 1200 gearbox, so the shifter comes up about 4 inches aft of normal.	+	== CA20 and CA18 SOHC ==
		+	CA18S/CA18E, CA18ET, and CA20S/CA20E are 2-valves per cylinder (8 valve head), so not as complicated as the DE models. However a CA20E turbo'd with stock rods will suffice for 300 HP if not taken beyond 6500rpm with 12psi. CA20 have around 9:1 compression.
		+	The USA CAs have better made-in-Japan casted alloy heads; the made-in-Australia castings are reportedly not as good. Also CA20 twin sparks are so economical for a 2 liter they really are underrated -- the CA20-powered Stanza got 43 mpg with [[NAPS-X]].
-	Or you can modify a L-series "stumpy" gearbox to fit the CA series front case. Then it bolts right in, shifter in the stock location for a 1200, and stock 1200 automatic driveshaft works too.	+	CA20 with turbo added

-	The stumpy Skyline gearbox, refers to the R30 Skylines with the L24 (six-cylinder) engines. The R30 came in sedan and hatchback styles.	+	== 4-valve CA20 ==
		+	It is possible to put a DE/DET head on a on CA20. See http://club-s12.org/v3/index.php?topic=23985.0
-	You need a CA20 or CA18 gearbox to get the bellhousing (front case) to fit a CA18.	+	269 HP

		+	drill out the head bolt holes, re-tap for the larger CA18DE bolts
		+	Turbo: Lancer EVO III TD05H-16G
		+	timing belt: extensive mods
-	To use the gearbox on a CA18, you must switch out the front section of the gearbox from a longer S13 gearbox, or a more common CA20 (e.g. 910 Bluebird Series 3) gearbox. There are conflicting reports about some of the swaps needing a different sized bearing to make this 'gearbox surgery' a success.	+	== 8-port ==
		+	USA and JDM CA16DE/CA18DE/CA18DET uses 8-port heads:
		+	<br>{{Upload|10243_4dd5529b6b83b.jpg}}
-	Beware: if the bearing doesn't fit right, the box will not last a long time. If the bearing is spot-on it can last for years behind a CA18DET.	+	There are two kinds of these heads:

		+	== Inlet Butterflies ==
		+	The butterflies are important for torque below 4500rpms:
		+	* If you are running after market ECU, and not programming the butterfly function in, then you may as well remove them.
		+	* If you are running a light flywheel and are only interested in power between 5000-8000rpm, then pulling out the butterflies is a good idea.
-	Once modified, 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.	+	== Carburetors ==

-	All gearbox options for the CA will need you to fabricate (or get someone to fabricate) a new gearbox crossmember to attach the gearbox to the floor of your car. In the case of a stumpy 5 speed just a piece of 40mm box steel will do the job. Bolt it to the rubber mount of the stumpy and then bolt it to the floor - add some spacers as required. Here a pic of a crossmember I made. (It only gets wider at the edges as I had some existing holes in the floor of the Datto I wanted to use.)	+	<br>{{Album|9029}}

Current revision

Swapping a Nissan CA engineᵂ into a Datsun 1200 is perhaps the most common high-power 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 is the factory turbo version. 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. On the down side, ^POST quote: "It does unbalance the car...lets not try to lie to ourselves."

Which is better - SR or CA?

• CA18DET = street legal in all States
• SR20DET = not street legal in a 1200 in Australia. A bit newer, a bit more power, heaps more parts globally, many more of these engines, so more parts for a long time

SR20 has more CCs -- and there's no replacement for displacement. On the other hand, SR20DET is too big for legal street use in some countries.

POWER
CA18DET 167 hp  stock
SR20DET 205+ hp stock

modded stock block (stock rods, pistons, head)
CA 400 hp
SR 400 hp
Cams, turbo, intake and exhaust are the mods
To go over 400 hp internal upgrades are needed

Naturally aspirated, bone stock
CA18DE 131 hp
SR20DE 140-169 hp

• There are more racing parts for SR engines. On the other hand, there are the same type of racing parts for CA engines (just not as many brands of them). There are even stroker kits for CA. It is easier to get parts like winged sumps etc for an SR. That doesn't mean the same parts are not available for the CA, it just means you need to look a bit harder.
• SR engine fits in a an unmodified 1200 engine bay. So does CA engine. Tie.

LOOKS - do you prefer the CA look or the SR look? Bulging muscles, or muscular athetic build?
Album 21787 Upload click to view

• CA is lighter than SR. On the other hand, both are far heavier than A-series engines. Yes, the SR has an alloy block, but it's still heavier than CA.
• SR is more expensive than CA in many countries. In USA, CA18DET is less expensive then SR20DET -- RWD versions of both are imported as used engines (both were sold in USA in FWD form only). In USA the KA24DE from S14 trumps both CA or SR non-turbo engines. Cheaper and more powerful.
• More 1200 fans are experienced at CA swaps, so there is a larger body of knowledge and know-how for the CA swap. On the other hand there are plenty of SR swaps too.
• SOUND: SR has a different engine note, which some may prefer. Others like the sound of the CA.
• SR has timing chain, which requires less maintenance than the CA's timing belt. CA coils on the other hand often go bad.

Cost

• Good used CA engines cost $400+ USD
• S13/S14 Front-cut cost $1500-$2500 USD
• Entire package with CA18DET and intercooler, fitted by a professional shop cost $20,000 AUD

   16. Get final engineering certificate

2-valve vs 4-valve

The 4-valve CA is a very special engine. The extra valves make it breathe very, very well which mean a lot more HP. All CA Double Overhead Cam (DOHC) engines have 4 valves per cylinder -- it's worth seeking out over the older SOHC versions.

* 2-valve CA18E  113 hp
* 4-valve CA18DE 131 hp

4-valve:
* CA16DE 122 hp
* CA18DE 131 hp
* CA18DET 167 hp turbo

2-valve
* CA16S  80 hp
* CA16I 
* CA18S  90hp (Single carb)
* CA18I  91 hp (single point EFI)
* CA18P  (LPG)
* CA18E  113 hp (EGI/port injection) 113 hp
* CA18ET 135 hp
* CA20S  102 hp
* CA20E  105 hp

CA20 and CA18 SOHC

CA18S/CA18E, CA18ET, and CA20S/CA20E are 2-valves per cylinder (8 valve head), so not as complicated as the DE models. However a CA20E turbo'd with stock rods will suffice for 300 HP if not taken beyond 6500rpm with 12psi. CA20 have around 9:1 compression. The USA CAs have better made-in-Japan casted alloy heads; the made-in-Australia castings are reportedly not as good. Also CA20 twin sparks are so economical for a 2 liter they really are underrated -- the CA20-powered Stanza got 43 mpg with NAPS-X.

Inlet Butterflies

The butterflies are important for torque below 4500rpms:

• If you are running after market ECU, and not programming the butterfly function in, then you may as well remove them.
• If you are running a light flywheel and are only interested in power between 5000-8000rpm, then pulling out the butterflies is a good idea.
