i read a post a few days ago about TB porting. i thought someone had said somehting about using an N/a Tb on a T2? i was wondering if there would be any benefit to this? i've got an extra n/a TB and am picking up a T2. also is there anyhting else i can use off an n/a upper manifold on a T2. like the fuel rail maybe?

 

No sense in converting to a N/A TB. Just mod and port the T2 one.

 

does the n/a tb flow more air or somehting? if nothing else i could put the n/a tb on while i port the stock t2 one right?

 

Id imagine the T2 flows better, as its the high end model fc.

 

They're both the same size (3 x 45mm), so they'll both flow the same.

 

bt eh linkages and adjustments would be backwards so you couldnt do it if you wanted.

you dont think mazda bothered making 2 seperate throttle bodies for no reason do you? a t2 TB is upside down to an NA one, meaning the front and back sides are different.
