my friend wants to boost his gsr with stock internals, how much boost would be safe, i heard 15 psi with a good tune is possible, possible?

 

6,7,8 for a dd will last a while (depending on trim and other components, as well as tune)

 

agreed...but with a really really good tune, 12psi should be safe for the "track" but if its a DD, i wouldn't push the boost past about 8 or 9psi...but thats just me....he could build that motor for $400-$100 (depending on parts used, extent of the build, source of parts...etc.) and push that 12psi or even more safely. but like i said, i wouldn't go past 8-9psi for a dd, and that much psi with a good tune wont really hurt the longevity of the motor much. (pervided he doesn't beat the hell out of it all day)

 

*sigh*

What turbo?

 

garret t3

 

Ok, how about something not so vague? What size T3? Super 60?

No more than 12psi with the stock honda map sensor, if he goes with a bigger map sensor he will be able to run more boost tuned correctly.

 

12 psi on a DD application is not hard to do and would be safe if you have the fuel enrichment to compenstate for the boost.

 

i think if he wants to be safe then he should stick to 8-9 psi. if he doesnt have the cash to rebuild the motor then tell him to stay within the single digit psi limits.

 

^ yea, i guess im just looking at numbers my crappy 270cc injectors will handle...im not sure what size the GSR injectors are. but with a better map and real good tune 12 psi will be ok, but i would just stay to 8-9...something like that.

 

you might want to get bigger injectors, stock hondas are only 240cc
