I'm not too sure, to be honest. I have heard that the k24z block has different water port vs. the k24a cylinder head. I saw 4piston do it before. Is more common to swap a k20z3 head. I also seen jdm k24z.

What needed to swap this into an rsx type s and will i have clearance issues?

[@Almostboosted]

No issues, you would have good hood clearance, probably but the oil pan might sit a bit lower. Just swap over from the type s engine the: knock sensor, crank sensor and if you want which I recommend waterpump housing with oil cooler. Intake manifold with everything. And the intake vtc gear along with the whole oil pump kit. And make sure to get your ecu chipped with hondata.

You tank try I know is been done with the 9th gen si k24a7. The problem is that your engine has sensor not in the same location than the k24a. For example like the crank sensor. On the k24z is located near the flywheel. And on the k24a is by the crank pulley.

Did you complete your swap? Just did mine on the 04 tsx same ecu and harness. It runs great but eventually would get misfires and knock sensor code. Do you know if I need to tune the tsx to work properly or I there is another underlying problem? In order to tune, I would need to swap the ecu to a newer ecu/immobilizer to get hondata or ktuner to work because the 04-06 ecu is not writable. Leading to more work/money which makes me feel like I should’ve went with a used k24a2 than the k24a3 jdm.

[@Almostboosted]

If you try swapping a different head, you would need to change pistons because it would make contact. Your best bet is swapping the complete engine. And yeah, you could upgrade everything else, but it won't make much power. I'm sure ktuner has flash for the ecu, but it won't be that efficient.

There is no need to change the camshaft unless you want better ones. And ecu yes if you are swapping into older honda chassi you need a compatible ecu that has been flash or chipped.

To be honest, I have not personally measured them. But every importer that I seen selling RBB 3. Is way more expensive compared to the RBB 1 and 2. Not sure if it might have the more aggressive cams, but I'm sure it has the slightly bigger intake valve.

[@Astonmarvin]

Been trying to solve the same riddle myself. Based on my reading even the later RBB3 JDM K24a's stuck with the 04 USDM TSX cams - not the more desirable 06+ K24a2 USDM cams. As a result, in terms of power specs the JDM motors out of the box wont achieve as much peak HP however they do tend to make up for it in torque. Silver lining: this makes a drop in cam even more attractive on the JDM motors especially with 40+ degree VTC
