Does anyone know what flange the factory 12a turbo manifold was.I have a factory 12a turbo manifold, and I'm trying to find out what flange it it so I know what turbo to get.engine is a half Bridgeport with streetported primaries and ported exhaust ports. I have a brand new garrett t25 that fits it, i looked up what flange that turbo is, and it could be a T2 , a t25 flange, or a t3.if anyone knows what flange the factory 12a turbo had, I would greatly appreciate it. Thank you

 

If a t25 fits it than more than likely it's a dsm flange so any 14b, 16g or 20g Mitsubishi turbo should fit it.

I would be curious to know this as well.

 

I believe the turbo is off of a nissan, if this will help

 

Turns out it's a T2 flange afterall which is very similar to a T3 but smaller, also could be interchanged with an adapter plate.

 

Thank you
