Sup guys, my stock gsr motor have taken a few beatings due to boost spike, but it was just a few times and so far so good.

Lately I have been thinking about attempting to build the motor a little simple beause I don't want problems in the future since i'm going to be a graduate student within a year and I don't really have any income to support car work.

First though, I have an idea of how much a stock gsr motor can handle but I want to double check with the people that have them turboed

I'm running a SC-61 on my stock motor and therefore It doesn't see boost everyday since it doesn't spool still liek 4500 rpm.

I don't drive it hard a lot, just few days here and then.
Also, i'm running 10 psi.

With that, would I get some opnions on how much power a stock gsr motor can handle under boost?

Any help will be greatly apperciated.

 

Search, it could handle 350 hp for a little while but people are pushing the limits of what stock motors can take every day.

I know what you mean, i see #s all day for stock GSR but I can't find much info on how long they last. I'm guessing I would be close to 300whp, just need it to last. I have been tuned since day one. Just need it to get me by all 4 years of pharm schcool

 

what manifold are you running? remember, it's not how many #'s you running that blows your motor, it's how much power you're making... with that said.. dyno tune your car, i think you might be running more than 300whp @10 psi with the right manifold/exhaust setup
