K24 Swap Parts Thread by SwapYour86.com and Pure Auto

He probably wasn't thinking this was a built motor with 16:1 compression, high flow head, ITB's or any other crazy configuration.



I posted the same link earlier in this thread, just fwi. That article shows a build that costs $10-15k+ for just the block and head. Add some titanium bits, dry sump, forged crank, etc and this engine is north of $20k. See below:

Ashikabi and I weren't suggesting the K24 wasn't the better platform for power. Perhaps throwing $20k into the FA20 motor wouldn't produce the same results, but it sounds like all the guy was asking for is 220whp. Clearly a 2.4L stock K-series motor will outperform the FA20, but this swap kit seems silly considering the cost versus the goal power. All he really needs is motor mounts from Pure and some tid bits. He wouldn't need a custom wiring harness that integrates with a Motec system and the stock wiring system, so that all stock features are usable. That is all we were saying.


@Icecreamtruk ...How did you settle on the K24? Have you considered the 2JZGE motor? 225hp/220tq stock. Obviously reliable. Definitely upgradable. Too heavy?

Agreed. He mentioned weight a couple times so I'm sure that's why the 2jz and LS are out. I understand the desire for a drop in system but I kinda thought the necessary parts already existed. I get that he's waiting to blow his current motor up but really just selling it while functional would probably be more prudent.

I don't want to argue with anyone, just seemed like he's waiting for an "expensive" kit with a bunch of features he doesn't want when he can do the swap right now for maybe a couple grand on top of the motor. Taking the CAN electronics out of the picture makes this whole thing so simple

Yes, weight is the main concern. Another thing, a k24 on the engine bay would free up a bunch of space. Why is space even a consideration? I have plans regarding aero that would be much more easily achieved if the motor wasnt as wide and far foward as the FA20 is.

Exactly, he could do the swap now and cheaper if he wants or put that same money into the FA20 with some weight reduction mods and be in a similar situation.

The K24 will be further back, but it looks to be the same distance forward, just fyi. The FA20 has the steering rack in the way, which is why it wasn't placed further back. The K24 has two extra cylinders, so I can't imagine it being too different in distance back. Maybe an inch or two difference. Maybe less. Perhaps Pure Auto can give us a measurement.

I noticed that after posting and deleted the statement.

Yeah, the front looks about an inch or so clearer than with the fa20 (from pics at least). There will be big gains on the sides, so I should be able to work more easily with that.

Just a comparison. Definitely seems like there is more room to work with. I would love to see handling comparisons between an inline four and the stock motor. If the car kept its characteristics then an inline swap could be in the future for me when the car is a track rat too. For now, I am happy with a boosted FA20.

Coincidentally, I hydroplaned my boosted FRS into a ditch yesterday. It has now been promoted to project car.

Very cool!

Pure automotive what level of integration are y’all shooting for same as your ls/2jz swaps?

same as LS/2J. cluster, drive by wire, stock fuel pump controller, stock fan controller, abs, custom traction control, push button start, cruise control, etc.

What will the header, mounts, motec setup run?

I know it sounds like a shifter will be an issue, is the S2K trans further forward?

I know many KMiata guys are starting to use the BMW 5 speed, thoughts on using those in the 86?

For those of us who plan to stay NA, I think having the option to purchase an adapter to keep the 86 transmission would be well worth it, compared to the headache of modifying the S2000 shifter, on top of the purchase price for that transmission, plus the need to use a different adapter anyways to connect the K motor and S2K trans... I get that the S2000 trans is stronger, but not everyone necessarily needs that in the first place.

This guy makes a good point. What all is involved in an adapter anyways? I'm not familiar with adapting transmissions. Probably some kind of bracket for the bolts and then something for the driveshaft?

Adapters are about allowing different engine and transmission bellhousing patterns connect to each other, plus setting input/pilot shaft depth correctly for the flywheel and clutch assembly used.

An adapter is already being used to connect the fwd K motor to the S2K transmission anyways, so the cost of the kit should theoretically be the same. Plus you'd be saving the actual cost of the S2K transmission, plus whatever shifter/console modification would be necessary. There would also be the chance of the 86 transmission actually staying in the same position in the car, further eliminating the need/cost for a custom driveshaft. That one I'm not sure of, but it'd be a nice perk if so..

For those of us whom this swap appeals to for the sake of losing weight and cleaning up the engine compartment, rather than being the basis for a high horsepower build, this would seem to be a much more attractive option.
