2V S281/4V TT Cobra swap need write up links!

C MY 4D · July 17th, 2008, 06:05 PM

I am about to start ordering parts for a S281 Supercharged to a TT Cobra swap. I have tried various searches but haven't had luck finding any writeups. Do any of you have any helpful links?

So you are pulling out the supercharged motor and dropping in a TT motor? That should be a pretty easy swap.

Yes but I am doing a 4v swap as well. Considering I haven't done a 4v swap yet I would like to read as much about it to make the swap as smooth as possible.

Is there a benefit to converting to a NA 4V PCM and using knock sensors? From what I have been reading they really aren't worth a shit on mod motors and I know if we go with a 03/04 cobra setup we won't even use them.
Have you ever converted a 2V harness? I know the COPs need to be relocated and from what I have read they need to have the polarity swapped. Is there anything else other than the alt. and COP wiring that needs be changed?
Are there any pinout issues between the various PCMs?
Or better yet what would you recommend doing with the electrical system as a whole? Should I just go with a complete 03/04 Cobra harness and PCM?
