Stock FA20 block - Force Induction

[86TOYO2k17]

one thing to consider despite the hefty price tag after doing this, and the questionable reliability, at 480crank hp / 420whp, and minimal weight reduction to 2700lbs power to weight at the crank is 5.625.

This is a few years dated but, top 10 power to weight ratios under 100k$, don't expect it to be as fast as most of these though (better gearing, weight distribution, a lot more power in general which is more important then power to weight as MPH increases etc..) but it should be able to hang for a little bit with most of them maybe 40-130mph (if you can put the power down and hook)

2017 Dodge Viper SRT ($87,895) – 5.24
2017 Chevrolet Corvette Z06 ($79,450) – 5.42
2017 Chevrolet Camaro ZL1 ($61,140) – 5.97
2017 Dodge Challenger SRT Hellcat ($62,495) – 6.29
2017 Cadillac CTS-V ($85,595) – 6.47
2017 Dodge Charger SRT Hellcat ($65,945) – 6.57
2017 Chevrolet Corvette Z51 ($60,450) – 7.17
2017 Alfa Romeo Giulia Quadrifoglio ($72,000) – 7.53
2017 Mercedes-Benz AMG C63 ($65,200) – 7.59
2017 Lotus Evora 400 ($89,900) – 7.88

Heres under 50k$, should be faster then all of these no problem. (Although put 15k$ into any of these and its game over.)
at 340 crank / 300 whp and 2700lbs PTWR is 7.95 and should hang with a 1SS or GT from a roll at least till around 40-120mph maybe 130mph

2017 Camaro 1SS ($36,905) – 8.1
2017 Ford Mustang GT ($32,920) – 8.5
2017 Camaro 1SS Convertible ($42,905) – 8.69
2017 Dodge Challenger R/T 392 ($37,995) – 8.73
2017 Ford Mustang GT Convertible ($42,440) – 8.79
2017 Dodge Charger R/T 392 ($39,995) – 9.07
2017 Mercedes-Benz AMG CLA ($49,950) – 9.2
2017 Mercedes-Benz GLA45 ($49,900) – 9.22
2017 Nissan 370Z Nismo (($41,990) – 9.54

Its currently stock, of course I will upgrade internals and fuel system. My top top goal would be reaching 450-500 HP Now some people say a turbo kit could do it after upgrading the rods and trannies, but my main focus right now is getting force induction.

What turbo kit do y’all recommend that in about half a year I could push my desired HP (After the upgrades)?

Will the stock FA20 block hold this much HP? Or would I need a built forged engine?

Also would appreciate some does and don’ts

I think you're shooting a little high with your power goals there considering how light this car is. I built my BRZ up to 340hp with a supercharger kit and E85 conversion and believe me it is plenty fast enough.

With some upgrades the BRZ can be a track monster, but it's never going to be a killer on the drag strip.

Plenty of people do it. Mostly when they blow their stock block and they don't have a choice but to swap it out.

That engine eventually blows up even while trying to drive at 10% throttle.

For our cars, I think 9-9.5 ratio is ideal for performance gain per cost. Since this is achievable with one of the basic FI kits and minor support mods like an oil cooler. And that makes a twin very close to a base Cayman.

Agreed, if its 9-9.5lbs per WHP and not crank. 2700lbs/285-300whp is a beautiful combination. Definitely pushing the limits, but not enough to be considered unreliable if done right.

I'd just get a different car if that HP was your goal. A waste of money IMO. It would be an insane car though....

My question is, why do you want that much power? Potential reasons:


1) Hobby, you want to do it because this is your toy car, you want something unique, not your DD, and you're bored


2) You live in a completely flat area and the only way to get your thrills is straight line runs down the interstate, but you bought the wrong car. Also you live in NC, not Idaho, so there should be fun drives.


3) You want to be part of the import scene, and talk about car mods more than exploiting the capabilities of this car, maybe an occasional street race. All good, respect to others and their hobbies, just be safe on the roads



I now have a Vortech supercharger on mine, making something meager, well under 300rwhp, and I can't drive it full out on the backroads here in CT. Just gets going too fast, with blind curves, bikers, walkers, etc., too dangerous. If you're planning on tracking the car (where you can potentially use that power), you'll need to spend a good amount of $$$ on mods to manage heat, traction, braking, etc. Depending on what you want to do and why, you might want to consider more reasonable goals.



If you're option #2 where you can actually play with that much power on the street (relatively safely), you might be better off buying another car, especially if it's your only car. Nothing sucks more than having your only car blow up

Go the Sikky LS3 route for 500hp. It would be cheaper in the long run..

How many "trannies" you plan on fitting in there anyway?

Maybe he needs a bigger back seat? Jk!!

New to the car scene and want to get 500 HP out of a 2 liter engine?


Maybe you should spend a little more time "in the scene" and possibly reconsider.

[86TOYO2k17]

You know how many people hated on and doubted Jeff Bezos. This guy could be the Bezos of the 86. You never know. Dream big. Why settle for 500 out of a 2L go for 600. Don’t put limits on yourself or more importantly your car’s engine.

James Martin from HRI tuning runs 550 hp fine.
