Does anybody know if a 05 rsx-s motor will be a direct bolt on into a 02 rsx-s?

 

Are you asking if the mounts bolt right up? The mounts will work.

 

Whats the difference in engines? And doesn't k-pro only work through 02-04?

 

I'm pretty sure it will drop right into an 02 rsx. You'll probably have to run the 02-04 type s throttle body though.

05-06 from the 02-04 has hp difference, different gear ratio, and drive by wire throttle body. I'm sure theres a few more difference from the different models.

Yeah, i think kpro only works on 02-04 ECU's so he'll have to get jumpers to convert the plugs to fit the 02-04 ECU.

 

will his 02-04 wire harness work? My friend rsx sucked up some water and the block went bye bye

 

bah to this idea. if you got money to swap, go for the k24 block. (if you've got a sweet deal, well.. duh)

 

correct me if I'm wrong, but I believe there is no differences (block) between 02-04 and 05-06. the head, camshaft, and a whole mess of other stuff is different too. but heres from crsx.com

The RSX Type-S Model Engine 2002-2004: K20A2

- Displacement: 1998 cc
- Compression: 11.0:1
- Power: 191 hp (*SAE Corrected 8/04*) (147 kW) @ 7400 rpm
- Torque: 145 ft·lbf (193 N·m) @ 6000 rpm
- Redline: 8100 rpm

*- The K20A2 was never SAE corrected/revised. If so, it would have been corrected to the HP shown above.

The RSX Type-S Model Engine 2005-2006: K20Z1

- Displacement: 1998 cc
- Compression: 11.0:1
- Power: 201 hp (SAE Corrected 8/04) (150 kW) @ 7800 rpm
- Torque: 141 ft·lbf (194 N·m) @ 7000 rpm
- Redline: 8300 rpm

so to answer the original question, yes, but if you are gonna run the whole engine (K20Z1) you need to swap out everything + ecu. I have an 04 so I dont pay attention to 05-06 people and their kpro problems, but I have heard of a persistant problem which leans out cylinder 3. search for it and im sure you can find more info.

 

yes it will fit i put a K20Z1 in my 02 after i blew the motor the only thing is that it runs kinda funny with the stock ecu so i recommend you put in k-pro

 

the differences between the two are, 3.115 crank pulley, as opposed to 3.465, 4.764 final drive, prc cams(more duration) countershaft driven speed sensor(so it is advised for you to use your k20a2 transmission) 8,100 redline, 8,300 fuel cut as opposed to 7,900 and 8,100. the 05-06 tranny seems to be a little more solid as far as the synchros go, triple cone carbon first through third as opposed to brass of the 02-04. though there is still sometimes a "false shift" for third gear when cold, but can be fixed with synthetic tranny fluid.

k-pro can be utilized, you must use an 02-04 ecu with for the k-pro daughterboard, a jumper harness, and an 02-04 primary o2 sensor.

the k20z1 is not drive by wire, that is the k20z3 in the 06 civic si, and other random k24's.

so, the shorter version, if you do a complete swap you may use an 05-06 ecu, or k-pro can be used to set up for a countershaft driven speed sensor. there is a box that can be checked to change it in k-manager. or you can use your 02-04 tranny, which would be the cheaper route. unless you want the final drive from the k20z1.
