I was wanting to know how much boost I can pull out of a vtec head and crv block. has anyone done it and how much HP you pull out of it.

 

A LOT!

 

lemme bust out the ht calculator

b20 block

+

vtec head

+

boost

calculating...

= cracked sleeves and spun bearings

 

i got the same answer on my ht calculator

 

it has also run a 9sec 1320' in a street car...... when they are built right.

 

B20's suck. Paperthin stock sleeves lead to explosions.

They can't even handle high compression N/A setups. Sleeving them is another story... in which case I'd use an LS/GSR/B16 block regardless.

 

your question sucks

 

was jason using the b20 crank too though?

B20 crank should be the same as b18 crank. Just different bore size.

stock, of course.

 

He asked if anyone has done it. Where has he been...like he is from blast from the past

 

b20 is an easy way of running mid to low 14's with i/h/e. Anything else = KaBooM. Buh bye $900 longblock. Just save yourself the headache and go b18
