Hello,

Posted in the wrong place so lemme try this again….
Im looking to swap a k24a4 out of a 2003 honda accord 2dr into my 1989 Acura integra.. I’ve had this car for a couple of years now kept it mostly original, I’ve painted it an had the exhaust done, I’m looking for more power cause this 98 hp D16A1 isn’t cutting it anymore.
I have the donor car an figured I can just “one for one” swap everything over, but I was told I needed an ECU from a 02-04 rsx to be able to do that, so I got one an I’m currently at a stop because the accord is a 5 speed an the ECU from the rsx i believe is a 6 speed, not sure if it’ll work.
Im looking for guidance on mounts, ECU, Harness, etc I’m sorry if some of this comes off dumb, this is my first k swap, I’ve swapped motor on other cars but never a Kseries.

thanks much 🤙🏻

pics are of a Kswap but someone else’s 1st gen integra, not in contact with them just found these pics on some forums idk where.

Not wrong, we didn't have an Integra swap subforum, so you were correct. I created and moved now your thread into Honda Integra subforum. Yours is the first one :). Thanks for the hint!

You may can start here: what do I need for a k swap in a integra? | Honda / Acura K20a K24a Engine Forum.

I would appreciate to see your Integra here.

Hello and welcome. Looks like most of the work is done.
I suggest you try our search engine as many of the topics have been covered.
Our archive goes back 20 years, so most topics at least have been covered to some degree.


There are several solutions for the ECU, especially regarding immobilizer. Here mentioned were KPro and KTuner. But there is more.

Ok so I’ve done a bunch of research and found a lot of controversial things..

lemme start of by sayin this car is a daily and will AT MOST get a crisp high five as far a performance goes

Some places here people are sayin if I have the whole running a driving Donor I could swap engine harness, ECU an Gauge cluster but would just need rsx axle shafts, not sure how much truth this holds.

Fuel system I’ve established that will need a walbro GSL392-400-939 inline pump, Works for me and easy install with the OSIAS FPR kit.

as far as motor mounts I’ve had recommendations on getting BBP 88-91 CRX k24 swap mounts and fabricating adjustments as needed I’m aware the trans on the Accord has different mounting points so might need to do a lot of fabrication but we’ll see when we get there.

thank you again for your patience with me an helping me figure this out!

edit**
The Type-S ECU i have, I don’t have a key or immobilizer for, buuuut “Kpro requires a key an immobilizer for them to install, not sure what the solution to this would be-IF I can’t use the donor car ECU.
