SA engine in a FB
I am looking to have an engine (I think from a 79) as a back up in a racecar. I would like to have it for the most part ready to drop in if my current one dies. I have an 85 which is gutted and stripped of everything that I dont need. I currently have a bad 12a that I can pull parts from to install on the 79 . I am running a stock stripped intake with a modified Nikki carb.
It looks like there are two ways to do the swap. 1) Switch to a lightened flywheel to be able to use the same 85 clutch/pressure plate. I would still use 79 front and rear counter weights. 2) Stick with the 79 engine as is and buy a 79 clutch to bolt up to the 85 Trans (this is what I am panning on doing) Questions: -Will the 79 engine bolt up to the 85 trans? -Will the 85 front cover, water pump, and oil pump bolt up to the 79 and can I now use the distributor from the 85? -Are the oil pan and oil pickup swappable? It looks like the 79 and 85 intake ports are the same |

It looks like the 79 and 85 intake ports are the same 2. the pan and pickup and pickup are interchangeable and identical. 3. both are 4 port 12A's. |
Done it a couple times. The only difference between an SA and an FB engine is the emissions control layout and the changes in emissions port location/function. In a non emissions application, they're interchangeable.
You're on the right track with the clutch. |
I've got a 6 port 13B and a 4 port 12A engine that I swap back and forth in my SA22.
I think the motor mounts are different between the two, but I just keep the clutches and motor mounts with their respective engine. I do have seperate carbs for both the 12A and 13B and I don't have any emmissions for either. I also have seperate headers and catback systems for both.... I guess it would help if I knew the origins of the mysterious 13B engine. haha :D |
Any one have a SA front counter weight they want to sell?
