yea i justed took my gsr out after blowing the motor and put b20 vtec, i don't have enuff money so i can't resleeve it ( heard b20b has weak sleeves) this my setup b20vtec, turbonetics t3, vafc, str blockguard, jg manifold vafc, and 370 rc injectors.
anyone have opinions on how much boost i should run till i have enuff money to build the block

 

The sleeves are 'weak' for the un-tuned.

You don't need to re-sleeve until you're runnning ~15-18psi +
when properly tuned.

Get a 'real' tuning tuning solution, AEM, Hondata whatever.
And your 370's are your limiting factor now anyway.

With your current management as it is: VAFC with 370cc inj. You won't be able to get much past ~8psi. NOT because of the 'weak' sleeves.

12.5 PSI is fine on the stock sleeves. If you go any higher you might want to sleeve it.

Mine cracked at 14 PSI or so , tuned ...

The B20 sleeves are of a one peice design rather than single sleeves
