I've searched and couldn't find a answer

 

mine has seen 11psi with no problem.

 

what do you qualify as a search, give me a turbo, I'll tell you what psi it can handle. B18 internals can handle 300 hp when well tuned.

 

You should be asking how much horsepower the stock block could handle rather than a boost level. From what I have seen, you can make 300hp on the stock motor safely with a good tune. I made 338 on a stock b16a @ 14psi

 

you can run 12lbs, but get it tuned properly.

 

i want to make around 275whp and it still be a daily driver (and im using a T3/T04E turbo)

 

u should reach 275 with 10 or so psi with that turbo. i saw 290whp on my gsr with 9 psi. As everyone on this forum will tell you.... do not push that much boost without getting it tuned.

 

i would say since it is a daily driver run like 6 or 7 pounds of boost. and slap on a manual boost controller so that you can turn the boost up when you need to...but for a daily driver i would say keep it at 6 or 7 pounds

 

 

PSI alone means nothing. "T3/T04E" doesnt really tell you anything definite either.

Can you make 275whp on a stock block in good health...yes all day. At what psi...who knows, that varies (and doesn't really matter)

 

This thread is from 2004 lol

The correct answer is 1 million WHP and 2PSI.
