A 50hp gain in a 2.0L 4 cylinder is a big jump. Your SR is factory rated at 145 +/- right, 120ish at the wheels? Unless you add some cams, raise the compression ratio, remap the ecu, raise the rev limit, and do some head and intake work 50hp is out of the question.

Start with the header, exhaust, high flow cat (or just get rid of it with a "test pipe", 1996 and up, no CEL = no fail emissions, I don't know how to prevent a light on an SR powered car, but I'm one cat down one to go, with no light on my QR), intake, SAFC. That's a start but nowhere near 50hp. By the time you get 50 hp you'd already be in the price range of a turbo. I don't think there is a kit for the B15 models w/ an SR, but I'm sure one could be adapted. If you really want more power but don't know where to start, you really need to consider researching first, reading some books, or ploping down the cash to have someone do it for you. Any way you go it's going to cost money. You could spend 1000+ plus just for a header, exhaust, test pipe, intake, SAFC and tuning, even if you install it your self and depending on which parts/brand you chose to go with. When/if you want more power you'll have to start taking the motor apart, cams, springs, head work, pistons, engine managment, and that's where it gets expensive. That's why so many poeple stop at header, intake, exhaust, pulleys, and maybe cams.

You need to look at what you want to spend, what you want the car to do, and what your options are. NOS will deffinatly meet your goals and is the cheapest way to go, no other mods needed, but it's hardly suitable for anything other that strait lines.
