Weighs the same.
No. Same deck height between B20 and B18. The B20 intake manifolds are taller- but you should swap those over to B18 manifolds anyway for better top end power.
Yes, they're made of glass. They're engineered to crack under stock power conditions, not to mention after 100k+ miles of abuse by the average owner who doesn't know how to maintain them in an older CR-V.
They are NOT fragile. The B20 sleeve will handle quite a bit of power. As far as limitations, you're looking at people with bad tuning or who are just getting too aggressive on their builds or trying to cut corners.
If you're going to run a B20 straight up in a dirt track car, it'll run great. Pack on 300hp more from boost or a bad nitrous setup- then we'll talk about how "fragile" the sleeves are.
