yeah del sol chassis are exactly like integra chassis. And I beleive your del sol is 95 or older (OBDI), and I think the SI civic that came with the b16 were all OBDII.
So you're gonna need a conversion harness ( www.RYWIRE.com is cheap ), integra motor mounts and the integra rear mount. I may be able to scrounge up all the integra mounts you will need, let me know if you're interested. And if the B16 you're buying came out of a 99-00 SI civic then ebay that thing, alot of people that are swapped B's into civics are lookings for them, I have the integra mounts you're looking for so you won't need it.
