b20 man by the time u spend money on the b18c u can build a decent b20. plus more torque and more power. and b20s have been proven to be reliable.

thats about it just waiting on a V2 final tune as ive installed new parts and need to make use of its potential.
Building a b20 vtec isnt that hard right??
I heard the b20 block needs to be reinforced is that true?.
Hear too much people saying bolting the head and new pistons plus a good tune can make a reliable b20 vtec.
If i can build one running at 110atw ill be happy if alli need is head + pistons + b20 block.
BYP tuned
correct.
you need to rebuild the bottom block to ensure it hand handle the VTEC power and extra pressure.
keeping in mind that the B20 never was built for vtec, so therefore you will need to ensure you have a breather kit, and the oil pressure return to the VTEC head otherwise VTEC will not engage.
thats right Adrian .. do u recall what cam pulleys it had? coz right now it still has adjustable cam pulleys ..but the cam timing was detuned by previous owner.
my final V2 tune would involve cam timing, s300 touch up, fuel delivery, 70mm tb matched ported IM.
correct.. the ITB's made the extra power .. dunno bout the exhaust size ...as mines got 2.5inch now ..
i initially wanted to Kswap ..but it was way over the budget ... 10k+ kswap ...might as well buy another car.. lol
