I was wondering what you guys think would be a better engine build to run 13 flat or even high 12's: a b20 buildup or a b18c5? Because the cost for a b20 build seems kinda steep and seems like u get the same amount of bang for your buck if you just buy the b18c5 and do a little work here and there. Besides that, you get more reliability in trusting ina type r motor, so what would you guys say would be best for your money?
