hmmmm, i think damn nail is making me lean towards a whole swap. i want the more power, so that would make sense.

 

mk so what ive gathered from other forums is they are different cams...one has a higher lift but a shorter duration and the other has a longer duration but a smaller lift. i want to say that the d15 has the higher lift and shorter duration and thats part of what makes it a sweet turbod engine.

 

It does not have a different cam, I have had them laying side by side and done measurements on both. Same exact cam. Either way I know for a fact the D15B likes boost. I mean I was making 170+whp on 7psi and 155+tq. Not bad, reved out to 8000rpm for me constantly, made power clear up to there also.

 

marty, you just convinced me to get it. i really like how you guys are batttleing over the specs and such of the cam and how much it likes boost. that said, im gonna get the d15.
