lsxrt
I got one the day they were released from Thunder Racing. I bought the fuel rails thru FAST, although Thunder should have them as well. You will also need a fuel regulator, and associated fittings, hoses and hardware. The whole thing will run you over 1500. I used an LS7 90mm because it has the ETC I need on my Hummer. Otherwise, you can go bigger if you need to with a cable throttle. I thinks it looks good under the hood, and the engine performs great. I don't know what the difference is, since I did not use the old intake after I built the motor.lsxrt.jpg
