maybe there would be an advantage.....abundance of cheap d series trannys is one instead of 1000 or more for b series transmissions. also the civic vx tranny is really
L O N G. it might drop out of boost range but it would hold it for quite a long time. anyway......there was a drag racer back in the day. purple/orange/green crx. fastest all motor sohc at that time. he had an accord f22a motor inside and he was running a d series tranny i believe. i dont know why he wouldnt run a h series trans but i remeber it was something that should not have worked. he made the adapter himself if i remember correctly. i know it isnt helping your question but maybe it did.
