[QUOTE="yacob.naif, post: 1594107, member: 565696"] Boost's just an easier way to read airflow. Someone said boost is boost, which is 1/2 right. 28psi is twice as much flow as 14 psi ON THE SAME ENGINE. 14 psi on a grand national might be 2x as much flow as 14psi on an srt-4. And 14 psi is out of a t4 is the same as 14 psi out of a gt28r but the 14psi out of the t4 might be cooler, but later in the power curve. Comparing different cars, or even the same car with different turbos is difficult. The only way to figure out what's going on with your car is to actually have it looked at. Spearco intercoolers are great quality, and one with pre-welded endtanks can be had on ebay for under $300. Aren't there people who run their nationals hot, as well? Never understood oldschool tuning. Anyways, i'd do a compression and leakdown test before anything, just to make sure the headgasket and rings are in good shape before you start adding boost. Shouldn't cost much at a shop, an hour of labor tops, or free if you can find someone with the equipment. Good luck! [/QUOTE]
