dabating building my 76'13b rather than selling, need some help and advise
 

i have a 76' 13b with 2000 miles on a mazda rebuild. i was planning on selling it and purchasing a streetported 12 or 13b near me, depending on how much cash i could come up with. im wanting to get rid of the 76 13b due to its lower power i suspect are due to its low compression. after thinking, wouldnt this be a good engine to use if i just got a set of higher compression rotors installed(GSLSE,89-91, or rx8 if possible)? or if i wanted to go for boost ive always heard the 4 port 13b is the best way to go, so i could use the low compression rotors and boost it pretty high? just need some help guess so i can make up my mind in what to do.
