any suggestions? has anybody done this with stock internals?

for moderators.... i have done my research and different people say different things this is to clear the confusion so dont lock!

 

sorry motor is a stock gsr

 

can be done on pump gas pretty easily actually

 

One of my buddies has a 380whp bone stock all motor gsr that he daily drives and has been doing so for the past 3 years now......

 

That's easy to do, sure.

 

380 and its allmotor ...u ****in lier

 

that be 1 bad *** gsr right there loldam near 400 n/a would be hauling bootay

oh yeah lier

 

LOL!!!

I really hope you meant, "all of the motor" is bone stock, plus the turbo, rather than it being naturally aspirated...

If not, tell your buddy to stop smoking that ish...but to contribute to the thread...

OP, this amount of power is done quite frequently & easily on stock B series motors. Peform a compression & leakdown test to ensure your gsr is healthy, select the right turbo to match your goal, get a good, reputable tuner and discuss your goal with him, put it on the dyno & let 'er eat.

And oh, yeah...click the red button below & have fun...

i tuned my friends 140k mile stock gsr to exactly 300 whp on 8 psi 57 trim. its fine just go get it tuned properly and dont cheap out on stuff that matters especially tuning and management

 

thanks guys will keep u guys posted on the results appreciate the input cleared up the confusion others stirred

 

the "search" function has been acting funky lately, don't know if the mods fixed it, but if u type in one word, the search results would come up with some random *** threads lol!

 

you will find that a lot of older posts suggest the motors cant take as much power as the newer posts suggest.


thats because people keep pushing the motors further and further to discover their actual breaking point.

i bet if u searched u couldnt find any 450whp D series pump gas builds... but, i have one.

its just one of those things. people used to say stock d series sleeves were "good for 400whp", same with vitaras... and then look at JFK making insane power, way more than people thought u could with those components.

with the right tune 300whp is NO problem on a stock GSR.

 

not only can it be done but it can be done efficiently pretty much dirt cheap
how do i know this my dd has a 900 dollars in to it and is easily over 330 whp.
