i'm in the process of putting together a cheap b20/vtec build i am going for pistons and rods for the block but i want it daily driven and knowing that the b20 sleeves are a bit weak just wondering whats the highest i can go with stock sleeves this motor is going ALL MOTOR.

you dont really need more than 12:1

so i would say 11.5:1

 

yeah thats what i was thinking 11.5:1 on stock sleeves but just wondering is there anyone actually running that right now with stock sleeves?

 

anyone? before i go ahead and do this

 

I run 84.5 mm 12.5:1 comp Wisecos. 93 octane chipped p28. No tuning been running like a champ for 2 years.

I AM RUNNING 11.5.1 AND NO PROBLEMS

 

The highedt we have gone was 12.5:1. And i wouldent go any higher. I say the max i would do is 12.1.

hmm???

anyways. im sure you could get away with high 13 compression.

 

so you had no problems with the sleeves splitting and was this daily driven?

 

NA you dont have to worry about the block, you can go 13:1 crp but only thing holding you back is that you want to keep it streetable, and with 13:1 your going to have to be on race gas every time. 11:5:1 you can use 93 oct and be fine, so the best cpr for streetable on reg gas is 11:5:1
