Ok... so whilst cleaning out some parts boxes... I came across an intake manifold for a 48IDA that used to be mounted to the motor in my 79 (motor was a 13B 4port from a 76 Cosmo).


The 12A that's in the car is pretty much shot, and I need to rebuild it anyway...



So I'm thinking of just creating my own 13B 4-port, using the 12A irons, S3 housings, and S5 N/A (or even Renesis, if I can get my grubby little paws on them) rotors.


I know I've seen somewhere that the water jacket holes are different... but I'm not sure.


Provided I go with this setup, will it all go together nice and happy-happy?

 

From what I understand, as long as you are using a GSLSE 13B and possibly e-shaft (not sure of this part) then you are good to go.

 

the old 13-B plates are the same as the 12-A. If I were you, I will use the ones with the largest/tallest ports especially in the intermediate plate.
