14.5 psi

 

my friend used to go 12lb daily driven before he got a k20swap done on his ekhatch .

 

stock internals?

I wouldn't go more than 8-10 keep it on the safe side if its your daily driver.

 

sorry i dint read the guy had stock internals. my friend has fully built. sry shouldve read clearer

 

Sorry should have made it more clear how much HP can the block handle

do you have stock internals? if so then 250 would probably be about what you can get out of it. with a good tune. as soon as you start building the motor you can make more power.

 

my boy sean is running 16lbs on a stock ls motor

 

Yes I have stock internals.

btw. why don't people understand that
lbs of boost doesn't mean **** unless you describe what size turbo you have

 

it wont last very long.
you must upgrade your internals if you are running 16lbs boost.
watch it blow soon

agreed, 16 sounds rather high, most people with boosted applications i have seen running stock internals run 8 psi safe and not really ne thing more than 12. 16lbs of boost on a cold day when the air density is higher just watch......

 

he could run 16lbs all day long on a dsm t25, but not on anything bigger
it's all about how many cfm's your turbo can or will push

Oh really?

16-17lbs on a 57trim .63turbine t3/t04e DAILY DRIVEN FOR 2 YEARS!

I tuned it and it runs great. I now have a built engine, but it had great compression till the end. 300whp seems to be a safe limit if you have a healthy motor. Get a conseravtive tune and you'll be fine

Ruben...you're an idiot

o man

 

So you say 300 whp is safe?
I rebuilt my engine last year, have less than 5000 miles on it
i just want to be sure.
thanks for all the help so far guys

 

i know 2 300whp LS motors. both have lasted.

300whp with a good tune.
