Any D-series engine will work up till 98 I believe
To keep the DPFI (not suggested) just swap the intake manifold, or wire your existing harness for MPFI (suggested) you will need a new ECU for this I believe
or go for a DOHC ZC 130hp drops right in ECU & Wiring are required for this

not that hard. convert it to mpfi as suggested above, get the mounts, etc. Do a search for it.

If you are going for a B-series engine, then you would have to buy custon linkage, or fab your own. If you stick with the D-series any manuel shift linkage would work

If you're looking for a easy and cheap swap you can find a D15b2 or b7 and stay dual point and it'll all swap in with plug and play. If you wanna stay semi simple with some alittle more cash a DOHC ZC will require you to get another computer PM7 or PM6 and also the DPFI to MPFI wiring and the CYP sensor needs to be wired. B16 would cost you the most with tranny, engine, custom mounts, custom shift linkages, ECU, jumper harness to the ECU and dizzy and vtec silenoid and still DPFI to MPFI conversion. You can swap almost any D series to your auto tranny. Converting to manual should be not be a priotity right now until you know exacty what you wanna do first.

I found a d15 at a local you pull it for $120. 150 psi on all four cylinders. I got it put in and it runs perfect. I think the timing might need to be moved up a little bit, its shakes alittle when at idle. It idles at about 750 rpms.

thats about perfect, you can retard or advance the timing by loosening the dizzy and moving the the angle forward or back till its just right

^ Yes but use a timing light or all that will be in vain. You could risk detonation or hot spots.

I'm still in shock that his stock DX motor is harder to find than any other motor.

What motors are available in your area???
