so, one of my boys is building a nissan RB motor for his datson and says that the 7M is one of the crappiest motors ever made. i know the 7M has its faults like any other motor but i also know that the 7M isnt the crappiest motor and is verry capable for good numbers and performance. my friend and i are now arguing about the 7M and why i think its a good motor and how he thinks its a crappy motor. i wonder if i can compair the 7M with nissan's RB? our debate is getting kinda rough so i need enough ammo to end this crap and make him know that the 7M isnt a bad motor. can you guys help me out? is this a doable debate?
