Which FI kit for automatic daily driver?

[ayau]

Coming from a 2015 WRX with full bolt ons and E85 making about 350whp. The power is nice, but I'm getting tired of shifting for my daily commutes.

I'm looking at potentially picking up a used automatic twin and adding an FI kit. Which FI would you suggest? My goals are the following, from highest priority to lowest. I'm indifferent between turbo and supercharger as long as the following requirements are met.

Reliability
Little to no extra maintenance over a factory twin
Ability to drive all year (90s in summer, 0 in the winter)
Ease of install (I may try to find a twin with FI already installed)
Ability to use flex fuel with automatic tune adjustment depending on E85 levels

As you can tell, I'm basically looking for a factory-like FI kit.

Your asking for a hard ask. Lots of good kits but imo SC what you described was the eddlebrock kit.

Simple.
Sell car.
Buy a new turbo Civic.
Or.... a nice base wrx.

Do you have a 2nd car? If not, don't do it. If you do, I'd go Vortech myself. But I wouldn't hesitate on installing any other CARB legal kit.

JRSC.

Sounds like Edelbrock E-force is for you

If all your concerned about is essentially getting an auto, you may be better off jist selling your current wrx and buying a auto\cvt wrx.


Especially considering the cost of going FI on a brz\86 and tou want to drive it all year rounf i suspect in snow conditions a wrx will be way better than a FI brz\86.


To go fi your looking at say arround $3500 for a fi kit plus usuall addons like catch cans, oil cooler. Then add fitting and about $1000 for tuning plis say $600 for flex kit to ise e85 and with e85 you will usually need bigger port injectors and a fuel pump


There will alwags be extra maintainance in an fi modified car over a stock na car, be it sc belts , more frequent oil changes and fhe usually niggly little issues that come with aftermarket fi kits.


My suggestion would again be buy a factory fi auto car like wrx

Unfortunately the factory WRX CVT is made out of glass and won't take more than stock power reliably.

The cheapest solution would be to buy someone's used auto turbo BRZ/FRS, but I'm sure those are very rare.

Fair enough, but the stock brz\86 auto might be a bit unreliable once you add a turbo and e85 pushing much more than stock wrx power levels

Yeah, that crossed my mind. Probably best to avoid non-factory FI car and trying to add FI if reliability is your top priority.

Probably better with a 340i or something with one of those new B58 engines for my daily lol.

The auto trans can handle.more power than the MT trans by quite a bit.

Edelbrock, JRSC, and Innovate 210 all seem pretty reliable and low maintenance. They each have pros and cons and different potential known issues etc. you would be best reading the forums of the specific kits to see others experiences with reliability.

As others mentioned the auto can handle more power then the MT, also shifts a lot faster and more consistent as well. Only real down side is you cant launch at such a high rpm but at least on my setup i just spin tires to the top of 1st if i take off any higher then idle. As long as the FI kit fits should have as good or better reliability on an auto compared to a MT. So nothing specific to an auto, your question could be, "what is the most reliable safest FI setup" transmission is irrelevant here.

For overall vehicle reliability less boost, hp, and a more gradual linear torque curve will be more reliable. You don't want a big sudden hit of torque snapping something. A little turbo like the SBD would be dirt cheap and meet these needs as well.

As for kit specific reliability and maintenance of the supercharge itself just read the forums for each one.

Glad to hear the auto trans is that stout. Makes you wonder why there aren't more auto twins if you're just using it for daily commutes. And why didnt Subaru give the updated 2017+ power upgrade to the auto trans? Too little budget to test with the auto trans?
