Greddy FMIC 2 row ?
 

I know that the radiator gets moved closer to the engine and stood up 90 degrees. I have a newer stock radiator ( aftermarket warrenty paid for it) Will i have room to keep the stock fans on the back and just do the fan mod. Or is there not enough room and i have to find a aftermarket fan.

There will be plenty of room.
You shouldn't have to worry about any aftermarket fans the stock ones fit and work great.

will that be enough cooling???

It depends, in most cases it should be.
Are you going to be using it for road racing or something similar?
The car will run warmer no doubt, but you have to make sure everything else is in working order.
A already weak stock cooling system doesn't get any better with something blocking the airflow to the radiator.

I have a GReddy 2-row FMIC with a Koyo rad. No overheat, @ open track, but the motor does run warm (110 C in 90 F ambient). Keeping the boost turned to 10 psi (0.70 kg/cm^2) helps keep water temps stay under control.
