I have a 1996 240sx sr20det blacktop T28 at stock boost 7psi. i have a bigger aftermarket intercooler. I have a 3 inch downpipe and aftermarket exhaust. i just purchased the walbro 255 fuel pump. So i was wondering can i safely turn my boost up after installing the fuel pump and to what psi???
Can I turn up the boost? How much?

I was told that the factory head gasket can hold 15 psi so I would stay under that. I know other people run more but do you want to take a chance if its a daily driver.

I have a s13 redtop with a t28, stock fuel pump, maf, injectors etc. etc., and set it to about 10-11psi, and it spools to 10psi by 3500k rpm, and accelerates hard till it hits a little over 4k rpms, then it pops and sputters...Any ideas? Didn't want to start a new thread, but I don't think 10-11 psi is good for the stock fuel system.
Just bought a walbro 255 fuel pump, should be in in about a week...
