2010 4tec 215 SCIC into a 2004 4tec SCIC boat

Hello,
I've got 2004 Challenger boat that uses a 4tec SCIC engine ( not sure the HP rating). I did a little digging and found that all these 4tec engines will bolt up to the same mounting holes so I figured what the hell and bought a running 2010 GTX 215 with IBR to use as a donor. I've got them both sitting and ready for the swap, just want last minute confirmation that the concept is valid and that I should be able to use my 04 ECU to control everything will fit and run properly ETC.

Thanks,
 
There are several differences that need to be addressed like TOPS system, correct CPS timing, CB venting, etc. but it is doable.

Hello, for the TOPS, can I leave the 2010 TOPS valve in and unplugged then for the original tops, swap in the oil pump housing with the TOPS valve and oil pressure sensor plugged in like normal. For CPS, can I just leave the 2010 wheel and sensor in like normal and expect the correct timing trigger to be sent or do I need to modify? For the CB venting, do I have to do any drilling?? I'd rather not put shaving in my block. Anything else I need to consider? Additionally, I bought the boat used and they put a cone style cold air intake on. What does the stock air intake look like and is there any reason why the previous owner would have switched? I'm really excited to get this boat on the water!

No, this will have improper venting and not work well. You need to completely remove the 2010 system and use the complete older one including the cam cap if you are using the old electronics.

Yes

The 2010 has the vent hole in it even though you don't need it but it will still run fine.

This is probably stock. Most of the boats have the open air filter from the factory.

Thanks for the responses, I ordered a new oil pump housing from ebay because mine was scored up from the catastrophic failure of the last engine. Will slap that on, remove the old tops, swap over the cam cap and try to get this thing running this week.
