I have a d15b2 with about 195000km. I recently did the multiport swap with the PM6 ecu. I currentl have 2 " full exaust from crappy exhaust manifold to a high flowing muffler and out. Also have stock intake piping with a cone filter.
I am very interested in getting an aftermarket cam. I have heard of the regrinds similar to the delta 260 and 272. I know that any real 10hp gain from these type of cams is going to probably be around 7000rpm. I honestly dont think that is the safest place for my d15b2 bottom end to be reving.

Are there any suggestions on the 260 or 272 type lift/duration cams and how their power range will affect the life of my d15b2 bottom end...before I can put in my b18 next year
