i still cant decide on what to put in when i get a s13. i know that the black top has 15 more hp off the bat BUT it is on an average $1200 more than the red top. and for me the 1200 is an issue.. but if you think about it to get the two engines the same hp you have to pay about the same amount of the difference in after market parts to get the two engines to equal power..so is the extra wait to get the money worth the Black top or should i just get teh red top...please help! :12dunno
