I was just wondering if anyone had any advise such as tuning, specs, etc on building a b20 vtec motor. Also if anyone has one, built one, or drove one could you let me know how it is. Thanks

there good motors if done right.. just get a h/i/e and cams and cam gears and your set for now then you can start saving up for the dyno to get it tuned... cuz if its not tuned thats what makes those motors fall apart. drove one i love it. it had i/h/e and cams with a chipped ecu and vafc and a 6 puck clutch... the car hauls all day!!!!

 

I have a b20b4 block wit a gsr head its pretty much a fully built motor except its not sleeved but its a good motor and its fast has good low end torque but kinda crappy mid range power but then again my vtec doesn't kick in till 7500 rpms. It clocked 12.9 @ 104 with full interior and sounds. The most commem problem is the blocks aren't as well made and the other b series cause its basically a bored out ls. My best advice is to build the block.

 

i got one i still need tuning but i like it better then my lsvtec becuase of the extra tourqe. just do it right get arp rod bolts and some after market pistons i regret not doing the pistons

 

they got good petential but not with the stock sleeves unless you are not doin alot of modifications to it.

 

the sleeves are fine for allmotor but any boost then you need to work them
