Question Reliability Mods

Whats up guys, I am looking at Getting an STi, or and STi swapped wrx when I get back from my deployment and I am wondering, what are some good reliability mods? I am trying to avoid repeated massive failures that I have experienced with my wrx. Thanks in advance!!

What are your goals besides reliability? Do you have a power range you want to achieve? Modding your car is never a guarantee to be reliable, but I would have to say stage 1 or 2 and protune would be the safest imo.

An AOS would be top of my list, oil pickup tube, not sure if I'd consider gauges to be a reliability mod but a oil temp gauge can't hurt. Send in your oil to get analyzed and possibly prevent a mishap. These come to mind first. Stay sharp out there!

Its going to be a DD primarily, with maybe some occasional track use. I would like alittle more than 300 whp. I already know that the KillerB oil pickup is a worthwhile investment so Thats definitely on the list. I just dont want a repeat of my wrx(Cracked piston rings, then spun bearings/headgasket failure)

The Killer B pickup, a smart tune and sensible driving = best reliability.

Anything other then stock can't be considered for a "reliability" mod. Keep it stock if you want it be reliabile. Without an idea of a year of STI you're looking at, we can't tell you much.

Reliability? Don't but an STi-swapped anything. Leave whatever you buy stock.

Preventative mods? Oil pickup tube and pistons/ringlands.

Buy an STi, whenever **** breaks, replace with name brand good parts. Use a stock oil filter, and change it every 5k.

A 160 degree, or any other lower than OEM opening temp thermostat is not a reliability mod. The car will never be fully warmed up and in that sweet spot for optimum combustion. The ECUs (especially on 08+) have tables in them related directly to coolant temp. Cold motor is no good in many other's opinions. Not sure how big a deal it is on the older models. 180 degrees is not a high opening temp considering combustion temperatures.

No need in starting another internet war over this 160 degree guys.

What year are you looking at?

Run good oil, swap out the oil pickup, get a good stage 1 tune and add a tenth or two of fuel to it, and then just keep up with regular maintenance.

The best reliability mods you can have:

1. Religiously follow the maintenance schedule listed for your car on subaru.com
2. Do not modify your vehicle
3. Do not drive like an assbag

4. Smoke cigarettes while everyone admires how badass you are for owning a STI

Buy a Honda. Seriously I was super religious on maintenance and running stage two levels and got a cracked ringland. It would be nice if subaru put better pistons in these motors.

Not driving like an asshat is easily the best reliability enhancing mod there is.

Regular maintenance / fluid changes, change the oil pickup, AOS, 2 core radiator and water wetter in coolant, maybe ceramic coat exhaust manifolds/ up pipe and or wrap them, undercoat/put dielectric grease on electrical connections if you're up north, clear vinyl or plasti-dip to protect paint, good tires... and not drive like an asshat.

People report lower egt's on cylinder 3 when they replace certain exhaust parts. Just my $.02
