I know that this question was asked before but I don't rember what the answers were.

do I have to mod any thing or can I just bolt up my origonal intake w/the carb on it?

 

Check out the 1st gen archive. There are quite a few write ups in there. I know many people here have done it. Lot's of stuff don't line up when swapping a 13b engine and using 12a parts.

No. Your 12A engine mount brace and oil pan also won't work with a 13B. Depending on what year 13B you use, the 13B front cover, engine mounts, and oil pan will have to be changed.

 

Ok!! what about just bolting the whole thing in my 85 GSL, do I have to replace the computer or anything like that, or is the oem harness GSL-SE compatible? cause if I can just throw the whole motor EGI and all without any headaches, I would just do that. Cause for only 500 cash this motor that I found is a screaming deal!

 

I doubt it, FC engines are different in a number of ways from SE engines.

 

500 bucks buy 79+80_rx-7's bridge ported housing and plates..

 

Well I guess THat I'm back on the search for a motor I was just hoping that I could use this one.
