psi stands for pounds per square inch. A turbo builds up pressure (measured in PSI) in an engine's intake manifold which means that more air and and fuel are taken into the cylinders at each stroke thus producing an increase in power.
carb: 4 to 6 psi tbi: 9 to 13 psi mpfi turbo: 26 to 32 psi mpfi non turbo: 41 to 47 psi
Non-turbo: 14.5 psi Turbo: 55 psi
35 psi with stock turbo or 49 psi with stock head gasket.
between 7-8psi.
12 psi in both ranges
You can put a turbo on your nissan but have the psi turn down to 5 psi if everything is stock, you should be fine. Then you'll have more pick up but the problem is you'll have to make room for your turbo by removing your fans in front or find a place to mount your turbo.
output is 2 to 7 psi.
48 to 55 psi, non turbo engine
depends on the turbo you use and in the psi you want. With a gt35 @ 7 psi you can have aprox 4 sec, and in the 1/4 of mile like 13 sec
Turbo 3 bar, or simply termed 3.0 bar, is whenever a turbocharger produced boost pressure of 27 psi, since 1.0 bar is equal to 9 psi.
Actually a genuine 16g turbo (not those cheap Ebay knock off turbos) can run a lot more boost than 19psi. Hell a 16g is just starting to hit its efficiency range around that 20 psi range. I've seen plenty of car run over 30 psi on a 16g! Trust me run 18 psi on one and the turbo's kick is so-so.... crank it up to 25 and that turbo will kick like a horse!!
14 PSI
