It has been done tons of times at this point, and is well-documented.
Updated Must Haves for K Swapping A Honda S2000 | Speed Academy
There's tons and tons of ways to do this; either the boujee way aka buying headers & intake manifold made for kswap s2000s, OR just cutting the flanges off of both and welding on K flanges. Personally, I'd keep the stock header and just cut off the flange and weld on one for a K. For the intake manifold I'd absolutely go with the Kpower Industries one: https://kpower.industries/collection...ntake-manifold
It has all of the provisions for your IACV, throttle cable, etc, and has the bolt pattern for your throttle body (B/D/F/H).
Aftermarket ECU is not required - you'd just need to make some modifications to the wiring. People sell custom harnesses or jumpers, but realistically the best and cheapest way is to just get a wiring diagram and figure out what needs to go where and what connectors need to be changed etc.
I will NEVER spend 5-7k on someone's tired ass second hand F series with 100k miles on it....As these cars continue to age and replacement engines become harder to source I simply cannot understand why people shell out bookoo money to replace the motor unless they're trying to keep the car "authentic". The K is arguably the better engine anyway.

yeah ive swapped the engine once with a F series. and thats this motor. i paid 2.8k with transmission and lasted 3 years still it shitted on me.
again the whole harness would probably be the hardest thing for me to figure out. as i AM WORTHLESS with wiring. and even trying to read a diagram. so id probably be able to do the rest if i did extensive research but i honestly need someone who has done this before to walk me thru this whole process. as i know issues with arise.. during installation. well see.. i know a K series is so much cheaper and i wish i can do this with ease.

K swaps are not all up-sides. There are negatives as well.
There are a lot of up-sides to keeping the F series. Not just for originality.
I disagree that the K is a better engine.
It has a better head design, however. And its dirt cheap. Don't get me wrong, it is genuinely an excellent engine. But...no...its not a better engine than the F series (without adding some kind of qualifier to that statement).
I would do objective research before diving into a K swap.
OP, you haven't found the root cause of your problem with your current F series. Its likely going to stem from someone doing something incorrectly. Would you agree?
Your original engine failed because someone forgot to put oil in it, right? The K series is not immune to that either.
This is probably gonna sound harsh...but the pattern of issues follows your attempts to keep rebuilding the engines with sub-optimal parts.
If you had bought a box-stock F series and swapped it in and kept oil in it...it would probably run until the end of time.

Something like 7200 in stock form.
8K after installation of a type S oil pump. But it would vibrate everything to the point of potentially breaking parts.
And it would have an abbreviated life span.
I've had a couple K20 and K24 swapped and stock K series cars. The beauty of a K24 is NOT needing to rev it. Most people only stretch the shifts to 8K when absolutely needed. Buy a K20Z or K20A-R if you wanna rev it.
Again...an excellent overall package and a lot of the downsides can be mitigated thru expertise. But...I wouldn't go out of my way to K swap a S2000 to "cure" it or something.
