why do you want the a/m manifold? because it looks better? if you're still using t28 there is no point besides looks. ive owned 2 different aftermarket intake manis and id only use them for top end gains, a tune is going to depends on your overall modifications, and if you already have a tune and how fine that one is already. its just a smoother flow that gives more hp, the throttle inlet is the same size. the runners only change the peak hp and tq

some vaccum lines are different, brake booster line etc, i'd use the threaded holes on the bottom to add nipples for boost/map to make it cleaner.
the intercooler cold pipe is diff
the fuel rail needs to be modded, one of the mounts needs to be shaved off.
the throttle cable bracket needs to be fabricated or use an s14 sr throttle pulley: NOTE it is VERY common that this mod puts tons of stress on the throttle plate, the bar that holds the throttle plate in place with 2 screws often SNAPS and screws get thrown into the intake. many people have been lucky and found the screws in the IACV.
coolant lines to throttle body are now diff lengths at diff angles
unless youre running big HP numbers, or a show car with a NICE bay, this is useless.
