-sct ba-3000 90mm
-mcleod rxt

I don't speak Arabic but I did serve in the Marine Corp during the first gulf war and I dated a gorgeous Jordanian girl and I picked up some of the language. Back to your set up. It looks like you have everything in order. But why would you go with a bigger upper pulley? Is it because of octane? Looks like you have a nice stable of cars. I would add the full tilt boogie racing to the irs. Who is tuning your car? Also what hand held tuner are u going with?

If you have the money I would get either kooks or American racing headers along with there x pipe.

I agree, with a whipple and all the mods you have it would be stupid not to do long tubes...
