I have a red top sr20 in my car....i am just wondering that how much boost can my intercooler, injectors, and my turbo can take. i have a walbro fuel pump upgrade already.

 

stock .... 40psi

er... injectors are the limiting factor. the 370ccs cut out at around 230-40rwhp

I think that is somewhere around 10psi ... sr guys help me out here

 

Everything depends on the condition of the units are in. You really don't have to worry about the intercooler or the injectors, they only have one purpose....and if properly maintained then they should last a while. The stock turbo on the other hand can handle app. 18 psi. and that's not saying you should go that high. A safe level is from 8-12 psi. depending on your driving style. BUT REMEMBER IF THE TURBO, INTERCOOLER, OR INJECTORS ARE IN BAD SHAPE THEY WON'T LAST LONG, SO TAKE CARE OF YOUR SHIZNIT.

 

Search in the future please

The motor: around...22psi-27psi(this is
stock)
Intercooler:ARound 10(stock sidemount)
Injectors: Around 12 I would say...maybe even hit 15-17psi
Turbo: 15psi MAX
