Is it possible (and what would it cost) to upgrade a pre-2017 86/BRZ to have the same improvements as post-2017 models? (+5 HP/TQ, better suspension, stiffer chassis etc)

Long story short, I don't think I could own an 86/BRZ without at least modding it with headers/tune, the torque gap is too real. I'm assuming it's a stupid idea to buy a brand new BRZ and then immediately cancel out the warranty by modifying it.

So I'm wondering if it's possible to get all the improvements from 2017 BRZ and apply them to an older model? I'm guessing this would not be cheap?

Unless you are drift king, you're not going to notice or be able to take advantage of 5 whole hp and a stiffer body. Let's be real, the car is better than 99% anyones driving ability here. What's that 1% more stiffness going to get you? Just throw a uel and tune on.

I bought a '17, wasn't going to mod it because it's dumb to void my warranty right away. It's now got a UEL header and a tune.

When you get a chance take a look at this:

The dealers have to proof that any modification directly caused damage to something that would normally be covered by warranty in order to invalidate, pro consumer!

Magnuson–Moss Warranty Act

The Magnuson-Moss Warranty Act (P.L. 93-637) is a United States federal law (15 U.S.C. § 2301 et seq.). Enacted in 1975, the federal statute governs warranties on consumer products. The law does not require any product to have a warranty (it may be sold "as is"), but if it does have a warranty, the warranty must comply with this law. The law was created to fix problems as a result of manufacturers using disclaimers on warranties in an unfair or misleading manner.

As far as I know, it's possible. If you search in this sub reddit, you'll find posts with pre-2017 owners doing exactly that. I think the post-2017 has the toque dip as well. For the extra 5hp, a ECU flash and a good air filter will do the job :)

Not sure about the chassis, that's kinda of a production line improvement.

The rest of them are more or less what we swap around all the time, and usually better than Limited spec.

Engine swap, and diff swap........ Might as well get a older model, ls swap it and make 500hp

Edit. Everyone. I'm talking the literal same 5 hp improvement here. There are some minor structural changes that can't be done without a literal engine replacement if you wanted the same 5 hp gains

Any other 5hp gain can be done with a drop in air filter..... But the final drive is still very noticeable.

Engine swap to get +5HP? I think you overestimated a bit...

To get the same engine improvements? Yes. There are structure changes done to the engine.

Here is a quick example of the changes to the block, valve train, pistons, headers, etc etc. Here is a huge PDF you can read up on with all the 2017 changes made that get the same +5hp over the 2013-2016 models https://imgur.com/a/1UZxB
