the d15b only came in 3 stage vtec in the 0bd2 models, obd1 is just regular one stage, correct me if im wrong and 450 is a little much as ive posted th is site before you can get the motor for 380 dollars or so at www.alljapaneseengines.com, if the site isnt working i have the guys email addy, also he said shipping in florida to a buisness would be like around 40 bucks, so its not bad
