You can find pretty much all the info you need on this forum, it's been discussed several times. Basic stuff will be besides the eninge, the wiring harness(people have modified the CA18DE harness in the pulsar to work with the CA18DET and it's ECU), the ECU, a tranny( CA16DE tranny from a '87 SE pulsar, will have a cable clutch setup and seems to be geared to acceleration more than speed and supposedly won't support as much power as the CA18 tranny but it should handle the kind of power your looking for pretty easily with a proper clutch of course. The CA18DE tranny found in the '88-90 SE pulsars will have a hydraulic clutch setup and will handle over 300 HP as proven by Boost_boy, he says it's also geared more for speed than acceleration), you'll also need the axles and shifter linkage to go along with whatever tranny you choose. You'll need all the motor and tranny mounts, a CA or compatible radiator so the hoses will line up right, if your pulsar doesn't already have a CA in it. Ummm I'm sure that's not all but other people will add in what I forgot.
