Miata makes sense, the K20 is awesome. Are you talking about K24 swapped S2000s though? I could understand that, higher displacement and slight improvement in peak power. But that's not a 2L engine anymore.

Honda has a habit of doing one-run models...

And a 200hp/2.0L will respond to bolt-ons better than a heavily massaged 240/250hp/2.0L.

And a K series doesn't have anywhere near the lifespan of a F series when driven hard.

nah. im talking k20. it seemed that once you mod things the k takes off where the f doesnt. not an expert at all though.

You sir are wrong k20 last as long as a f20c or even longer. My k20 honda took so much beating track days after track day for 5 years it never burn a single drop of oil never had no issue. Sold it to my buddy and he boosted the car to 483whp on stock internals and shit is still running like a champ. For the guys that don't know, alot of s2k owners swap the f20c out and put in a k24. It's already been proven the the k series has more potential then a f20c. The 9k redline is all achievable in all k series engine. There a reason everyone favors the k20 it has been swap in to all kinds of car and makes redicolous power and reliablity

Well, the K has much less horsepower to start with so is that really fair? lol

I can't find any K20 swaps, only K24s but I'm not looking that hard.

Out of the box, it seems like the F20 is more well suited for making power though; oil pump is OEM designed for 9000rpm, shorter stroke and longer rods, bigger valves.

I suppose one could use a K20 if you are going to build the crap out of the engine for boost since K20 parts might be easier to get or something, but that still seems like an awfully weird swap to me. The F20C is basically a better K20 lol.

I haven't laughed this hard in a while.

The first time I drove the FR-S, I actually noticed the torque dip and how it felt kind of slow in the low RPM range compared to my 140hp 1996 Celica. Not a terrible engine but should not be on top 10.

This x1000. After driving hondas k20, the fa20 feels slow and underdeveloped.

that said, i will forever love the B-series <3

If it's more fun to drive than the FRS... Does it matter?

I agree with you, he was incorrect. The k20 is one of the most reliable engines avaliable. You can beat on that thing for 10 years, then supercharge it and beat some more. Truley inspiring engine.

Pretty sure F20C is the best..... Factory wise.... Honda quality at its best. Imagine if FA20 redline as high as it does, we wouldn't be chit chatting like this.

Agreed. The entirety of the s2000 is absolutely amazing. The f20c is mouthwatering ..

What's upsetting about this whole thread is that you can't walk into Honda and find anything appetizing anymore...

Honestly, I always wished they would just come out with a K24 or K20 RWD Prelude
