Built Turbo K24 Swap?

[Calmwhiteguy]

Hey folks
I'm ready for a lot more power and I've been looking at a lot of articles and a lot of discussions on FA20 FI and engine swaps.

I have opinions about the 1, 1.5, and 2j platforms as well as LSomethings however one of my performance gurus recommended an engine I haven't really thought much of which is a k24.

The reason he mentioned this engine is because stock engine and turbo can get me a reliable and consistant 400+WHP. If I splurge the extra $4,500 we could dump in a total engine rebuild and aim closer to 800+ WHP. This seems like the most affordable and long term durable option from the research I've done (I've never owned a honda or payed really any attention to what they put in their cars).

The reason why I like the idea is
A) Reliable (as much as 450+WHP can be)
B) "Economical"
C) Very close to FA20 weight
D) Unique

I couldn't really find much of ANYTHING about built k24's going into the ft86 chassis does anyone have any opinions about such a venture? I've seen a youtube series that was last updated on wiring a year ago and someone below posted their white 86 with a k series swap but not a ton of seriously useful info aside from k swap the world
Or am I really that crazy for considering something except a giant v8 power plant or JDM 2jz?

I suggest lighting a bunch of money on fire.

An ls will get you more power for less money and be more reliable for the same amount of work.

The cost of swapping an engine (any engine) into an 86 is just about the same. The only part where the cost changes is, how much money you spend on the motor/trans. and what ECU solution you use. This is the reason why an LS is almost always the answer for "cheapest" of all swaps. Plenty of aftermarket support, you can still go to any GM dealer and find any part needed and it's a simple motor to upgrade and work with while giving you a start at 300-400+ HP. Prime Motoring is doing a K24 swap in their 86.

The main thing to keep in mind on this swap right now is that there is no CANBUS translation on it for an 86 swap. That means right now there is no system that will support working your AC, ABS, traction control, power steering, among others. Now, Pure Automotive is doing a F20 (S2K motor) swap and they would provide a CANBUS solution for that swap which may or may not be similar to the coding needed for the K24 swap.

Edit: Pure is providing a K24 CANBUS solution (see below)

We have both F20C and K20/24 CAN solutions in process. Just need to test them out before they are released as we never sell anything that doesn't 100% work.

I'd much rather dump that money into fully-building up the FA and boosting it.

A fully built FA20 may still throw an arm rocker through the valve cover, may still get a P0016/18 code whose fixing may require up to replacing the ECU (among other sensitive annoyances of the FA20), while also still needing to beef up the transmission, which cheapest is swapping a CD009 from a 350Z in place at a cost of around $4k.....


After adding up building the motor, turbo kit with all supporting mods, upgrading trans, you're already in swap money territory where you'll get a more reliable, proven and known motor and transmission that will hold strong for years to come.

[Calmwhiteguy]

Thats my concern. Im not engine biased and really couldnt care less about what is put in necessarily.
The FA20 and its transmission have proven to be pretty weak.
I have friends in the community who have gotten properly tuned well innstalled FI who yell at me saying the FA20 is reliable and to "do more research" but it always comes back that in my WHP goal range many FA20's have blown RIP.

At that point theyre giving me 6-8k for install and supporting mods no built motor. So what add 4k for a built motor and you just spent 12k on a FA20 capping out at 500~WHP on e85 everything maxed.
How is that worthwhile?
Spend 12,000-15,000 and suddenly I have a turbo k24 at 450WHP 92 octane... build the engine and swap the turbo forn something bigger down the road and from other builds I could be around 800-900WHP if I felt like it.

It seems like you would be crazy to build an fa20 like that.
These quotes are if I didnt to a shred of work myself. Obviously things get a lot cheaper if I do my own labor.

Do you guys have an ETA

[EAGLE5]

A custom engine install is like a custom anything. You're going to end up spending loads of time and money on troubleshooting, and things you expected to work will either not work or will work inconsistently. Don't blaze a new trail with an engine unless you know how to do the work yourself or the money just doesn't matter to you.

I'd personally like an EV FR-S. A Spark EV would make a great swap.

This kinda depends on your goals. If you goals are to regularly autocross, track, drift or do any other high intensity racing with your car then a swap makes sense. If your goals are to have the power for often doing rolling races on the highway against the occasional Mustang or Vet then maybe all you need is a built FA20. If you want 450whp+ for spirited driving on the mountains or the occasional highway onramp pull or to beat that Mustang that revs on you that one time then it is your car, but 450whp+ is overkill.

If you want 800hp then I'm guessing you're more of the highway racer type. Honestly, do what you want; it is your car, but just know that a 460hp GT can be had new at $35k and the used models with 435hp can be had for under $25-30k. Here are some supercharged units that are like new for under $40k making 700+hp:

A 450 hp+ ls wouldn't cost anywhere near 12-15k and would weigh less than a boosted honda motor. It would also be infinitely more reliable.

Yeah LS is still on the table it's just pretty heavy. Im still 50/50 on the k24 vs LS its just on paper if I didnt do any of the work (absolutely no time to do it and ive got a racing company who does a phenomenal job in Momroe WA) the K24 ends up being cheaper.
They've got a k24 s2000 with 1008whp as their drift car so they're got plenty experience with it.

Heavy? What is your source.

People who have their 1000+ HP k24s in a Honda 2000 (I love F&F) have deep pockets. They literally show you the end result and not the failure or the sleepless nights or let you know the unsurmountable time of all the individuals puto together to get the car together for a few drift events.

From the post, it seems you think this is a quick and easy route. It's not. How much do you think a turbo strapped to a k24 would reasonably weigh? I'm thinking it's pretty damn near an ls1.

I don't think you appreciate the amount of resources that goes into making a Hondacura engine run 500 or so HP at the crank.
