808 Muscle,
I picked up a Saleen Extreme HE from eBay. I did what is quoted below. However, I used a 40 amp relay (I think it is because the 40 amp relay I had was water-proof). I can't recall the draw on those fans but they are Spal fans and the Spal website was helpful with fan specs. I could not match the fan connectors so I ordered a two pin connector kit from another eBay seller. If you hard wire the fans, you will have to cut wires to remove them and I did not want to install them that way.
The install is relatively straight forward. The Saleen HE has a 1 inch hose inlet so expect to account for that. It is pretty wide but still fits. I opened up my lower grill to utilize the extra size. The lower bolts on the fans sit too low for a stock GT lower splash shield. I had to cut 4 relief holes in the shield to make the shield fit. I bet that is not an issue with a Saleen front fascia.
