Some interesting things - K24Z1 (07 CRV)

We got one of these in the shop today and I was eager to rip apart whatever I could get to just to see what was diffrent. I initially thought that they carried over the original K24A1 to the new 07 CRV but I was suprised to find a K24Z1 in its place. Keep in mind these are crappy camera phone pics but all the same they work fine.

First things I noticed:
- Intake manifold is stamped RAA, not plastic. However there is a plastic chamber UNDER the metal one with the same sort of exhaust recirculation system as the K24A1's plastic manifold.
- Drive by wire
- Aluminum oil pan that is NOT connected to the transmission.
- From what I could tell with a mirror/flashlight(didn't want to pull the VC) it is still the 2 lobe intake 1 lobe exhaust design. There was no real VTEC crossover when I took it for a test drive. Could not find a head stamping.
- The valvecover breather seems to be a bit raised and smaller in size with no coolant lines routed around it.
- Same metal intake manifold design as the Accord.
- It appears to have either a relocated oil filter, or an actual oil COOLER. I couldn't get much light in there...4wd makes it very cramped.
- Either 2.36" Exhaust, or 2.5" - Pretty big from the header back.

Thought I'd just give a heads up that there is a newer version of the CRV K24, Hopefully another one comes in sometime soon so I can grab a bit better look at it. All in all it seems to be an improvement over the K24A1, I am however not certain of the compression OR if it would take a K20 VTEC head with the stock pistons. I guess that info will come in time.

If you have anything to add, or other knowledge of this engine...please post it here!

looks exactly like the rdx motor from the bottom (oil filter, oil pan, tranny), which would make sense since it seems as though the rdx and new crv are the same chassis

Post more info on the K24Z1
Well it has the same crank as other models. Pistons and Rods off the K24A4 (BS crap). The oil filter is in a different location. It actually comes off the girdle facing downward making it easier to reach from under the car. Cylinder head is also crap RAA head like the Accord/Element. What else do you wanna know?

Please beware of this head and piston combination. It can cause seriuos problems due to the piston to valve clearances. Glad to see you put it together, but that isnt the problem its the clearance. Yes change the pistons to either CRV or TSX if you use this block and your on a budget. Its not worth the risk to run the stock pistons of this block
