First of all two kids so that is why four door second of all I have owed a 97 civic that started out as a 1.6l vtec that got hydro locked and swap to a b18 and missed have vtec this was it

now I have the 04 with the d17 and want bigger motor I don’t race it I just want to swap it and the only thing I think that can be easily put in this year car is a K24 so that is why I want to do it and who has done a four door for the longest time while I owed the 97 I want to buy a four door and swap the si motor into it until I was pushed into a guard rail on the highway and had to part out the 97 I step away from Honda for a while and it would make me happy to have a four door with a K24 and no I don’t want a accord or crv so what if it is a four door and I don’t want the si

Well my 04 TSX is portly at 3,300lbs.

A heavy 04 Civic is 2,700lbs. K24 fully dressed is about 100lbs heavier than a D series fully dressed so..... I mean 500lbs is 500lbs. And with limited HP weight is king.

I mean I went through all the trouble of plucking a K24 out of a 12 SI to plug into an 11 CR-Z. All said and done the CR-Z is only 300lbs lighter than the Si. But a K powered CR-Z is COOOOOLLLL. Or so they say anyway. Okay, it is cool. And I would much rather have the CR-Z over the 9th gen SI, so ugly.

Even the TSX with the factory body kit? Like a strange mix of JDM and Euro trash. Only thing I don't love about the TSX is the steering wheel looks like it comes out of a big rig. Why the monster wheel diameter?

I mean go for it. Hasport makes mounts. The halfshaft options are out there and documented. You can do the RSX PCM and retain mostly everything. I do believe you need Hondata to reprogram an output on the RSX PCM to control AC in this swap. I think there is even a power steering line kit to use the K series power steering pump on the Civic rack. The big torque of the K24 will be a really nice addition to a daily driver.

Also my thought is Honda should have made every EX model With the best motor instead of just adding VTEC to the original motor that came in DX and LX

EP3 was K20 but that is just being pedantic. But having something in the same generation come with a K series makes the swap a bit easier.

You are certainly not the first to take this on. I would recommend searching for some completed builds and take notes on what is needed to complete your swap.

Or just look in the stickied thread that says "► FAQ's and Guidelines - READ BEFORE POSTING!" since there's a K-swap guide in there.
