So, I really am a beginner when it comes to most automotive things. Would new engine internals help the longevity of my engine with the Mountune tune? Benefits/Downsides?

Only if you’re looking for more power. The stock internals are only good up to a certain point and application. If you’re wanting to increase boost beyond what your tune is making and maybe spend more time near redline, then it’d be worth the purchase and effort.
...But once you start down that road in the pursuit of moar power, then you’re going to be replacing more than just engine parts. Clutch, diff, trans, cv-joints, etc...

If you are going with a simple tune keep the engine bottom end stock. If you are going to turn it up to 11 then you should consult your tuner/speed shop.

I’ve had the tune for 2 years. Just wanted to know if it would improve longevity for the engine

If mountune stands behind the tune you’re running on stock internals and you’re not running it hard for long periods of time very regularly(track use etc) it should be fine.
Also if you’re like me and you spend $2k building an engine capable of bigger power it would be a tough temptation to not then also go for a more aggressive tune and bring the longevity back to what it was.

Long story short is that you should keep boost low in order to have the best reliability. The problem with aftermarket forged internals is that even if you run no boost, aftermarket forged internals do not have the same heat expansion rate as OEM intervals so you will require rebuilds relatively often compared to stock

I agree with WRX.
1. Rods - If you are having enough power to require Forged Rods, you probably have busted 4 or 5 other things that should have been upgraded first. You don’t need them.
2. Forged pistons - I have raced cast pistons for year without issue. Forged pistons are better if you are above the redline rev range for the engine. They also help if you have significant pre-ignition but they are no bandaid. If preignition is a problem you would be better served by getting better gas or a better tuner.
3. Camshaft/Spring/Titanium Keepers - These are all tools of the devil and will definitely will decrease the longevity of your engine. The cams increased ramp/duration and lift plays hell on the springs and uncontrolled spring hamonics will saw through a titanium keeper like nobody’s business. I know. Unless you are a racer and plan to replace these parts often and plan to get an expensive education, I would leave these alone.
If you are wanting to boost performance but keep OEM reliability, I would talk to someone on a forum or at your tuner’s shop that has done it, liked it and driven it for a year.
