J-spec car or no?

I run 30lbs on my stock turbos (but I could be fibbing!)

I dont go more then 18 to 20 MAX in nice cold weather :)
some run up to 22psi, but it really hurts the turbo life


on a side note, with meth injection people run 26psi without problems

18psi on pump gas and even then its good to be cautious (check your egt's and a/f's with a wideband). People run more on race gas (100+ unleaded), but you are slowly entering the inefficiency range of the stockers. I would aim for 18psi with a good tune and wastegate spring mod and you will see not only reliability with the stock twins but a mad power curve for stock turbos. After that its time to go single...
