uh oh, now that I am getting a gt2871, I'm afraid I'm going to spend more money on my car

so, what will it take to make a sr20det motor hold on to 20psi of boost on the said turbo SAFELY and RELIABLE as a daily driver?

rocker arm stopper, aftermarket headgasket and valve springs are nice head upgrades that will help keep your motor safe. any other aftermarket interals are welcome also. at high psi like 20+ though expect things to break sooner or later. how much hp are u looking at 350rw?

cooling: better radiator, efans, lower temp thermostat and a home made cardboard cooling panel if you're poor or one from ebay haha.

fuel: bigger injectors, higher flow fuel pump,

drivetrain: probably a 6 puck clutch.

hm, you are right, I shouldn't even be thinking over 15psi for the sake of long term reliability
