ok... i have a ls in my hb... i just bough a gsr head... compleat and taped for lsvtec... no can i pit a crv crank in my ls to make cr bvtec.... and what one is faster.

 

i believed that a crvtec requires a b20 block from a crv

 

c i heard... that the crv... b20 crank will fit and change your stroke so it makes it 2.0L... just like a b17 crank will fit in to a b18.. or b16...

ls and b20 cranks are the same stroke. 89mm. only difference between the blocks is that the b20 has a bigger hole (84mm) compared to ls (81mm) that is why b20 is a 2liter.

 

my opinion just stick with the ls bottom end its way stronger and cheap to get another one if u ever do something stupid on it lol

 

true!
if you want to make your ls to 2.0l. you have to sleeve your block to 84mm.
everything else is the same

 

cool... thx... so will i get any better peformance out of a 2.0l ls-vtec... does ant one know what ls vtec runs for hp to the wheels

 

Depends, I have a all motor LSV bored out to 1.9 with P73 pistons, running 12.5 : 1 compression and single layer head gasket. Crank balanced and edged, egale rods, arp bolt and BLOX stage 2 valve train setup, on indivisual throttle bodies and a s300 hondata. It's a beast, she pushes 251 at wheel, and 208 lbs of torque. Haven't ran it yet, I am waiting on a JDM ITR tranny....I guess what I am trying to say is, you get what you pay for...And the reserch botton, is your only friend!
Best of luck in your new project!

oem p72... on eagle rods... w/12.5:1 CR.... 1.9 w/stock crank... whats the bore?

anywho, back on topic.

im in the reverse situation. ive got a b16 head [not installed] and b20b in my car now ... i cant decide if i want to build the b20, or pick up this LS real cheap....

probably end up going LSvtec.

 

if you are not sleeving/rebuilding the b20 on your build, it may be better to go ls.

 

a am going to rebuild eather the ls or b20... what one will give me a over all faster and stronger running car... o ya i plan to dino tune and run to 8.5krpm... any other toughts
