12a first gen to carbed 13b.
 
Having issues hunting down information on all the parts I will be needing to do this swap. I will be using a s4 6port 13b but I am not entirely sure what and all is needed for the swap besides the engine and carb setup. I have searched and everything I have found seems to be people going to EFI.

Anyone know what I need for this?

Parts u will need:

Gsl se oil pan & front cover if u plan on keeping ur stock omp lines,& 1 of 2 things either slot ur engine bracket or swap out ur crossmember w a gsl se crossmember since the 13b is bigger.

u will also need to use an oil pickup tube from a 1st gen, and if your gonna just run premix and eliminate the OMP any 1st gen front cover will do. i just got done swapping a S4 6 port in my FB, check my sig ;)

So I could hunt down another 12a front cover and slap it on the 13b and use the dizzy and what not from the 12a?

Or am I going to have to use GSL-SE stuff still. I am trying to avoid EFI and go with weber 48ida since wiring is not really a strong point of mine lol.

I have a DCOE 45 with racing beat manifold that bolts to the stock 6 port lower for sale. Its on my summer daily driver and works awesome.

12a dizzy is the one to use

I think he's planning to use the stock fc external oil cooler, since it will bolt up to a fc engine.
