It seems to me that the only real reason to lay the rad. forward is to gain access to the back of it. This access comes in handy when connecting the water pipes to the radiator. If you add sucker fans with a high CFM rating (ie: flex-a-lite 220) you should theoretically improve your cooling. You can add the fans with the rad. in the stock position but connecting the pipes will be difficult. The hood vents are not needed and many people will tell you not to cut up your hood to add them. The airflow will still be directed under the car as is is now.
I'm in the process of doing this now and it's really a simple mod. I just need to find a decent rad. shop to flip the brackets for me, extend the in/outlet pipes, and devise a solid mounting method for the fans.
