Cosmo Oil pump on a 12A
 

I need to know if a Cosmo or 13b turbo oil pump will work with a 12A front iron, or if a gsl-se oil pump flows the same.

the 85+ engines have a different bolt pattern, so they won't fit. depending on the year of the 12A the GSL-SE would have the same pump

Would you know off the top of your head if the se oil pump would have enough flow for a 12a based 3 rotor? I'm worried about starving it for oil. Not really looking to go dry sump. The build will be N/a and plan on running a higher pressure oil pressure regulator.

My '85 12a omp is 2-line and the -SE is 4-line, and they have a different bolt pattern (and take different block-off plates). I'll take pics when I get home this evening.

I'm not looking at the omp. Its the actual oil pump inside the front cover. The omp is the first thing to go in the trash on my cars.

Ah, my apologies, I misunderstood ya there.

No biggy. I'm working on a project that has very little info so there will be plenty of misunderstanding.
