Im doin this for a friend.He want to know how much power he can build on stock gsr just with a block guard and arp stuts.

 

Your friend is asking a pretty open-ended question; realistically it cannot be answered. I could assume so much from your question. I am sure your intentions are to help your friend but the biggest assumption I am making is that your friend should not be boosting if he can not ask his own questions. Boosting is a responsibility. With that said, he can make decent power with a stock engine; but there are so many factors that it is not even funny.

I am not even sure what direction to point your friend in but the FAQ section is always a great spot to start. Read, read, read, read, read, and when he has scoured the internet of everything boost related re-read everything 100 times.

Here's some great reference.

Been stated a million times, give or take 350whp regardless of turbocharger. there are other threads on this please take the time to look

 

I usually don't like Telling people to search, but it's been covered so much that almost any question related to boosting a gsr has been asked time and time again. Like others have said, read, read, read, and then if you are unclear about something, ask a specific question about what your confused about. Also, make sure you give as much info as you can when asking a question, as it will be easier for someone to give you an answer. Simply asking "how much power xxx will make" is usually not enough to give any type of accurate answer as so much stuff is dependant on one another. For example, one turbo may make xxx power with one mani, and xxx with another. Take care.

 

make sure you get a good tune i dont push more than 300ish on my built bottom end just for reliabilities sake

 

thanks guys for the opinion.Now he understand what i talking about.Go build if he wanna make power.

 

prob make close to 350 with a nice intake mani/ TB

 

probably around 300 unless its on e85..then you can assume 350 or so..

 

a decent 350 shld be enough. i have a built motor nd i dnt even wanna push over 300 plus cus i drive it daily

 

my stock gsr made 363 hp on a 35r, depends what size turbo "your friend" is interested in

 

My stock gsr makes 360 at 13 pounds.
