*ca18det Faq* updated 3/16
Basic Info
Displacement - 1809cc
Bore - 83mm
Stroke - 83.6mm
Compression - 9.5:1(DE) 8.5:1(DET)
Horsepower - 135 HP @6400RPM(DE) 175 HP @6400RPM(DET)
Torque - 115 ft/lbs @5200(DE) 166 ft/lbs @4000(DET)
Tune up stats
Timing marks -The six marks on the crank pulley read clockwise are -5, 0, 5, 10, 15 and 20 degrees respectively.
Timing - 15*BTDC(DE(T))
Idle speed - This is set via a valve solenoid on the intake manifold. In the center of the plenum aiming to the front is a valve with a gold cylinder with a plug on it. Unplug it and adjust the idle speed with the 10mm bolt on the back of the valve then plug it back in.
Idle speed - 800RPM(DE) 750RPM(DET)
Spark Plug - NGK PFR6A-11 or equivalent Gap - 1.1 mm
Fuel Injector - Top feed, 370cc
Oil filter - Fram 3682, 3614 or equivalent (4qts with these)
How to PROPERLY set the timing on the CA
-warm car up to NOT
-remove decorative coilpack cover
-remove the plug going to the coilpack on the #1 cylnder
-remove the 4 bolts holding the coilpack in place
-remove the coil pack
-get a spark plug wire
-attach one end to the spark plug
-remove the rubber boot on the coilpack
-using electrical tape, attach the other end of the plug wire to the coilpack
-plug the coilpack back in
-set coilpack someplace that allows the body of the unit to be grounded
-attach the inductive pick up to the plug wire
-attach positive and negative power leads to the battery
-start the car
-point timing light at the crank pully
-it should read at 15*BTDC
-if timing is incorrect loosen the 3 bolts that secure the CAS and adjust left/right until the timing is at 15*BTDC
-retighten the 3 bolts and recheck the timing
-turn off the car
-reinstall the coilpack, plug the coilpack in, and reinstall the decorative cover if desired
-enjoy your newly timed car!
*Important Facts*
- you can use any low imp. top feed injectors (dsm 440's will drop right in with the lower CA o rings
- stock bottom end has been proven to hold over 300hp with proper fuel management
- these engines are a minimum of 15yrs old, so expect some parts to be in need or replacement
- its not a bad idea to tear down the bottom end an inspect main and rod bearings
- install is almost identical to the sr, same with mods to the wiring harness
- head design is better than sr CA-8 port head /SR-4 port head
- KA clutch will bolt right in, one of the pins on the flywheel just needs to be pulled off with vise grips
- use ONLY the CA18ET water pump, the DE pump does not align correctly when the DET pully is used, unless you use the DE pump and the DE pully
- iron block and all forged internals
- lighter than the SR (44lbs)
- any KA radiator works perfectly
- s13 SR hot pipe will work for a fmic, but not smic
- SR downpipe works fine with the sr o2 housing
- SR t25's and t28's are both upgrades
- nismo sr/ka mounts will work but engine sits about an inch higher (nismo does make CA specific mounts, havent found them in the states tho)
- KA sohc maf works
- ca18et and ca20e bellhousings will bolt onto your ka tranny with no alignment probs, and youll have a longer 5th gear
- head bolts are a 10mm allen wrench
- oil filter is same as 240sx unit
- 3 wire universal o2 sensor works fine
- stock flywheel is 26.8 pounds
- flywheel bolts ARP #151-2801 (Ford Pinto 2000cc)

that site lists alot of good part numbers but basically the rwd det is the same as the fwd de that came in the 88 pulsar nx se, some parts can also be used off the 85 200sx with the ca18et
