Does anyone know where/if there are hp/tq numbers or (god willing) dyno sheets for the HKS FA20 complete engines run NA? Ideally, I'm looking for info on the Step 3 top end one (23011-AT005) to ballpark the capabilities out of the box but the entry level Step 0 (23011-AT006) would be helpful too.



Goog-Fu doesn't seem to be turning up anything, HKS is tight lipped about mentioning any power numbers in any of their documentation, and even the state-side vendors selling the engines don't post any numbers on their websites. VERY strange.



To head off the inevitable comments ( :slap: :) ), yes, I know $42k is a bit off the wall for an NA FA20 but I'm trying to do a comparison here for research. Also, the AT006 Step 0 is only $20k and keep in mind an IAG Stage 2 or Crawford short block alone is about $5k and that's nowhere near ready to drop in to a car and go, especially if you wanted an all-new engine and not pieces salvaged from a donor.



Thanks!

Setups and dyno's very so wildly I wouldn't want to put numbers on it if I was them either.

The thing I don't buy about this though is that you can flip open a Jegs, Summit, or any number of performance catalogs and pretty much every available crate engine will have the HP/TQ specs. The manufacturer can safely run an engine dyno in-house and post those numbers. That's what really makes me think the numbers are underwhelming at best.

Honestly, they are so prohibitively expensive for the majority of owners, you might have to pioneer it. That’s the only real way to get data.

Fair enough point. Though companies like Blueprint who build those for companies like Jegs probably drunkenly trip over more SBC's then the number of FA20's HKS builds a year.

I got my IAG stage 2 built, timed, and shipped longblock for less than 1/2 that price. Spending 20k on an FA20 is crackhead tier imo. Also if you are going NA you dont need a stage 2 either.

Pretty much. You can go order a complete NA K24 with a warranty rated at 340hp, 360hp, 400hp, 440hp, etc on up from 4Piston but they get there through volume.

That's a whole other discussion that (for the most part) starts and ends with not being able to get my daily driver inspected (yay, NY). Past there, the lack of torque and the sound combined with the all-in conversion costs and modifications makes it a less and less appealing option (for me). I do like the HP bump and weight drop though.

The only difference is the HKS isn't a long block, it's a "complete engine". I take that to mean drop-in, connect existing air/fuel/water/electric connections and turn the key (plus break-in obviously), just like any other crate engine.

If you were to start tacking on intake manifold, TB, coil packs, etc., it's easy to see the price climb. I'm not saying it's in any way rational to spend that kind of money on one of these engines, but I can see how it could get there.

On the Stage 2, it never hurts (other than the wallet) to over build. I have a custom Merkel 400ci SB in my Vette that I way over spec'ed. This year makes 20 years it's been in the car with no more maintenance than plugs and oil and it still runs like a champ. Expensive, yes. Worth it, definitely. Especially when you amortize the value. If you had no car payment, would you spend less than $150/mo for the next 20 years knowing your car would give you North of 500 all day every day?
