Can a stock internal 2003 g35 with 150k miles handle 6-8 psi?

 

sub'd for answers. been wondering about this myself...

 

If the motor has been taken care of and tuning is right on, then I dont see why not

 

You must do a compression and a leak down test to be sure.....but i woudnt

 

Also be honest and ask yourself if you have the means or a contingency plan (other mode of transportation) when things go bad.

I don't have deep wallets myself but at least I can live with periods of downtime oh my car

<----hasn't driven my STOCK g in nearly 10 months

Sure it can. Or it could go boom on the dyno one pull into the tune. you'll never know unless you try, some guys have had great results on stock blocks, but unless you have $10,000 to just throw away don't even consider it.

one thing i have noticed with a modified car, is always have a backup plan. I had an evo for a few years. Stock it was a great car, but as soon as i started messing with the turbo and fuel and such, things went terribly wrong. i was months without that car. It finally got to the point where i had to buy a little honda civic to bomb around in. THEN i bought my G

 

From a boosted stock block owner. I have been through it all. Plan on having a back up plan. I am only running 5.5lbs of boost with 66k miles. Already cracked two pistons once. It is all about the tune and supporting mods. Find a extra stock block (about $1500 on average) and plan on building one. Its a hit or miss with that many miles. Good luck!

 

Do it, if yours blows up I have one for sale.

 

Stock block, 86K, 9 psi 373 rwhp, no issues..other than trying to self tune the PMAS and not having done that before...lol

 

150K i wouldn't do it..
