then i would buy a D15B sohc VTEC motor from Hmotorsonline.com. I would buy the whole swap with TRANSMISSION. put a clutch in it, maybe a cheap ebay header an call it a day.

$1000 wont get you ANY DOHC vtec motors. MAYBE an ls motor MAYBE, but thats on the CHEAP CHEAP.

this is assuming you do all the work yourself
