Even if you plan on modding it, you can still take advantage of a new car warranty. Most of the body, and other features will be unaffected no matter what modifications you make. Do what I do and start with wheels/tires, suspension, etc... and you can do quite a bit without voiding the majority of your powertrain warranty. The warranty is selective, not all or nothing

But yeah, if you plan on swapping in a V8, and tearing the whole car apart within a few months, maybe the warranty isn't quite as useful, lol.

I was thinking new wheels, first the winter ones (safety first) than the summers.

No V8 for me yet, who knows what the long future lies ahead. Maybe down the road if i get a new DD, i can mess with it more. I always wanted a project car.

Crap, you're right. Turbocharged. Gotta read.

When EBF kicks in it's really obvious, Like when you try drifting but fail @ it & front tire just brake/drag like no tomorrow even with traction off.

Am I reading the curb weight numbers correct? A 20-30lb gain depending on the model?

The rest of their lineup is going modular isn't it, won't be as bespoke and probably won't be as good.

Hopefully there is just continues updates like 911s through out the years...(&Subaru basically use it to test their new tech first before putting it in WRX)

I mean that's what tada san said he wanted to do few years ago....

Save your money and mod the 15!!!!!

Obviously I don't really know. It just makes more sense for it to be the same since they're coming off the same assembly line, and they've shared every other color except for the brand unique ones. It's an educated guess rather than thinking a name means anything. WR Blue is a perfect example of this.

They're pretty good on the Corolla, but they still lack the width of HID. LED does consume less power though...

If that's the case, that confirms that they're 100% bolt in and compatible. Here's hoping it gets rid of the crickets.

Amazing how far LED technology has become, a palm size flashlight now can output like 1000 lumens.

Head with LED's could take up an entire thread, but they generate less heat for their equivalent output because they're more efficient. (Their efficacy is also better usually, and efficacy has been coming up over the years). BUT, the components can't handle their own heat, so a thermal solution has to be found to remove the heat from the diode. So it's a little bit of both, they output less heat for the light output, but they have to have a thermal solution to deal with the heat or they'll fail.

So I Google FA20:

"The FA20D features both direct and port injection (Toyota's D-4S injection system) and Subaru AVCS variable valve timing system. It is used in the Subaru BRZ, and is identified by a Toyota engine family code known as the 4U-GSE, which is installed in the Toyota 86 and the Scion FR-S.[7] According to Subaru, 0W-20 oil is recommended."

and under that:

"FA20F: A version with Subaru's own direct fuel injection and twin-scroll turbocharger was introduced in 2012.

Displacement: 1,998 cc
Bore: 86 mm
Stroke: 86 mm
Compression Ratio: 10.6:1"

So the 86 uses Toyota's DFI system, even in the BRZ, but the F model uses Subaru's DFI system, and it's supercharged? Is it basically the same engine? Curious how this affected the new 86 version.

Curious as well as the FA20 in the WRX is a bit beefier than ours.

They have quite a lot more sound damping material in them, as well as a few added braces.

Then brembos.

This. Most people interested in that sort of thing have already gone the 4.56 or 4.88 route honestly, but an OEM option would be quite the difference

.

My 2015 Rogue has LED headlights and they work perfectly, perfect width and depth, the self leveling makes a world of difference. I think the GT86 had a self leveling setup where as the BRZ had a manual adjustment, a self leveling system would really help.

Ofcourse, there are reinforcement ribs outside & few small changes But it's not high rpm "friendly" like ours. Then again the 2017 FA20 engine gets different kind reinforcement too that's around the crank & head.

(You can miss-shift our engine to like near 8.5k & it will be fine on twins with updated cam/valve (2014 late model onward), try that on WRX one.)

Looks like my car still has the old style fuel pump. Build date is 3/16.

Depends on the market. For example EU regulations require cars with HIDs to have self leveling and headlight washers, the GT86 and BRZ in Europe would have these as standard equipment.
