well it is about 8 lbs of boost depends on the day and how many miles are on it. Mine is an 2003 and it is pushing like 4 lbs of boost making 800 HP on the dyno stock.
I've put down 44 psi with a tune.
I think around 14-16 psi
14.7 psi
7 psi is safe to boost on a stock d-series motor
35 psi with stock turbo or 49 psi with stock head gasket.
The 87 turbo z was 6.7 stock, but when they get older they could lose boost do to age. It could also be your stock boost gage not reading the correct boost. You should buy a after market boost gage and a boost controler, with a high performance exhaust, intake from K&N and a boost controler you should get huge horsepower gains. Just make sure you dont go over 11 psi without an intercooler and run high octane gas. If you want to go over 8 psi, you will have to remove the stock pop off valve.
The stock boost of a 1987 Toyota Supra Turbo is 6.8 psi/0.46884349504 bar.
I believe it is in the ball park of 14 to 15 psi of boost. That is what my turbo talon run. Edit: A stock 1g DSM (Talon eclipse laser) has it set at 9-12 PSI. while the stock gauge says 14 sometimes it should not be trusted. get a aftermarket boost gauge and find out yourself
that awnser is wrong its 17 psi and 15 psi for a 95 to 99
it is usually running about 8 or 9 pounds stock but if you get a boost control the most you can push is 15 pounds
While it's very changeable via tuning and physical modifications, I believe the stock WRX is 7-8 psi, and the stock STi is 14 psi. To get really into it, an Eaton M62 supercharger installed with stock pulleys is usually between 2-5 psi, and an Eaton M90 installed with stock pulleys will net 7-9 psi (just incase you're cool enough to try going the route of supercharging)
i hear with a propper tune with a stock turbo on a 2.5 sti the highest safe boost is 23 psi
