k24a2 Swap (Page 1/3)

What up.

Im starting a new thread to show off my new project!
im starting a k24a2 engine swap on my 1984 2m4 (tired of dealing with a 40 yo engine)
I only know of maybe 2 or 3 other people whio have done this swap so i wont have much documentation to help me out on this one, so im going to document it to my best ability on this thread.

I have a low budget and not a whole lot of time so i wont be updating this thread super often but I will as much as I can.

engine shipped today so im excited to actually start working on this thing.










currently in the process of removing the old duke out of the car.

UPDATE 1 (9/28/24):TRANSMISSION

I managed to get my hands on a pretty decent transmission for the K series.

I ended up going with a 5 speed manual out of an 04' Honda RSX. I thought 6 speeds would be too much lmao. I'm hoping to get a stage 3 clutch and lightened flywheel for a snappier drive and I have my eyes on a few different kits.



My back seat is all stained now lol.

Currently I am working on getting the ECU and stuff wired up and hoping to get the engine running on a stand. I haven't actually worked on much, mostly just collecting parts for the build, I haven't done much assembly. Ill go more in-depth with pictures of parts and the set up I'm going with within the next week most likely.

One minor thing I have done was I did a little rust repair and repainted the engine bay. I was super lucky since most if not all of the rust was surface and I didint have to do much actual rust repair.

Before


After


If you have any questions let me know.

this is my first time legitimately attempting to document things so if you have any advice/criticism on my work, let me know please it would be greatly appreciated.


UPDATE: 11/4/24

As of now I've pretty much compiled all of the parts needed to get the engine running on a stand. This includes a 2004 TSX ECU (ended up buying the wrong one but can still use it for testing) the electronic throttle position module, the throttle position sensor, starter, control panel, adapter harness, engine harness, and a fuse/relay block.



Since I am currently going as cheap as possible with this project, it also means I'm going as stock as possible. This is going to be a challenge for various reasons. The stock 2004 Acura TSX comes with an electronic drive by wire throttle body set up. Thankfully, it uses a cable to move the throttle position sensor in the engine bay rather then having one built into the pedal. I have to figure out a way to tie the Fieros stock throttle cable to the throttle position sensor. In the future, I plan on swapping in an Acura RSX drive by cable throttle body when I get the funds to get a K-pro ECU.

I've also replaced the Flywheel with an RSX flywheel since its almost 5 pounds lighter then the stock TSX flywheel, hopefully will improve the throttle response a little bit.

While all of this is fine and dandy Im having some huge issues trying to get power to the ECU when on the engine stand. The ECU harness I bought sadly did not come with a wiring diagram so I've been having to fiddle with stuff until it works, and it has been taking forever to get it done. its a literal rats nest and has been the worst part of this project.



the good thing is, once the engine runs and I know that it can run reliably without issues, most of the work of fabbing it into the car will, not be easy persay, but it will definitely be a nice change of pace compared to dealing with the electronic rats nest this engine needs.

hopefully next update I'll have the engine wired up and running. once that happens I'll be able to provide a much more in depth break down of the set-up I'm running.

There is a Facebook page dedicated to fieo K-Swaps. Something I have been tossing around as myself.

If anything i will keep an eye on your build.

not a huge fan of k swaps tbh. I wish you the best of luck and I will say this.
please address gaskets and any known defects with k series engines now (I know there is a few)
Spadesluck AUG 08, 07:41 AM
Why are you not a fan? They are a very popular motor that make proven power. All motors have some sort a issues for sure.

I would definitely echo what CarterCarbs said. Make sure you go through the engine to a degree, and change out all the gaskets that you suspect are a little tired. It'll be a lot easier to do it now, than it will be to do it later when the engine is installed (thinking timing cover, rear main seal, etc.).

Don't worry about what they say here. Just look at what the rest of the world does with K24a2. Like someone said there is a facebook group specifically devoted to swapping this engine into a Fiero. Those engines are great and it is a popular swap.

yeah didnt think to much about that but ill definatly will be going through the engine before install.

the engine only has a little more then 45k on the clock so im not super worried about stuff like the head gasket.

im hoping to get it running on an engine stand to make sure every thing is good before final install.

oh just don't like them honestly. nothing really against them but my favorite honda engine is an F22 or F23 but definitely a j30 to drive or even the j32 out of a acura tl. I'm actually doing a g-swap (h head onto f23 block) with a Buddy so there's that.
as for this case? just really enjoy both the iron dukes smooth crappy power and the v6 screaming at high revs upon downshifts and just hearing that beautiful sound of a 60 degree v6
