how much boost can a b18b block handle? ive been told 20 i just wanna make sure everyone agrees that is safe enough not to blow it

 

a b18b can not handle 20psi on stock internals, who ever told you that is a complete moron. I wouldnt run more then 10psi with out swaping out some guts to be safe. Homemadeturbo.com is your best friend with all things you want to learn

 

well what would i have to change out? im still new to this shit...lol

 

if you seriusly no nothing about boosting a car then your very first concern should be to learn about it. Go to www.homemadeturbo.com and start reading all the FAQs and beginner guides, it will answer ALOT of your questions and help you choose a good set up for your desires.

To run 20psi of the motor is gonna need alot of work and that should not be a daily ran setting because thats gonna cause some issues regardless of how well the motor is built

 

i've seen 14psi (60-1) on a stock b18b with block guard & head studs.. but it was tuned to perfection. I wouldn't recommend going Any higher than 8 without having head studs & being tuned properly.

go study!

 

Ya twenty is a lot I've heard of 14-15 on stock sleeves tuned but I dono if they had done pistons and such...

 

yes.. supposidly stock sleeves can handle 450-500hp .. it's the pistons / rods that will fail. so if you went with forged internals, & made sure the cylinder walls didn't sway via block guard, & used stronger head studs.. u should be able to pull 450-500hp out of a b18 bottom end without sleeving.

i'll make my attempt to prove this when spring rolls around!

 

LIES!!

 

lol.. u wish!

i've got Four b18's in my garage right now.. 3 of which are mine! if i blow it i've got more!

 

Seems like you have a lot of wasted money into 3 B18's just sitting around, when that money could be put to use for other parts...just my two cents.
