I plan to put B16 vtec head for my b20 ,and some typer intake manifold ,big cams ,etc.. but with stock b20 sleeves.
Since we know b20 sleeves are thin ,im affraid it will cracks if i give it high CR.
Any sugestion for how big CR this sleeves can handle?

 

this topic has been covered many times....

up to 13:5:1 "tuned".....

HAAHAHAHAHAHAHahahaaaa

 

lets wait for a second opinion since a chick chimed in

before you go lifetime on my ***, im just kidding

 

female running 12's h'mmm where were you 4 fours ago!

 

We have 102 octane here, and one more question is how high is the safest RPM limit if it was everything inside this Shortblock on STOCK condition ??
Im sorry GAL ...

 

with 102 octane you will be plenty safe at 13.5:1 with tuning. although there are some guys who say there is not much more to be gained once you go over 12.5:1. personally i would aim for around 13:1,

save rev-limit on a stock B20 bottom end? if your using the stock rods then 8000rpm would be pushing the limits. if you get a set of good forged connecting rods you can buzz it up to 9000rpm or more as long as you can make power up that high.

hope this helps

FORZA ITALIA!

 

thanks no-vtec ,i see a lot of people in this forum running stock bottom end b20 with v-tec head above 200 whp
