Eaton Swap Brackets

[decipha]

I have an 03 marauder and a complete 03 cobra engine minus the bracketry. I haven't been able to find the swap brackets as it seems those that were making them do not anymore. Does anyone have the dimensions for them? I have a full machine shop and a cnc machine. I could make them if need be but Id rather not tear the car down and have it immobilized to design the brackets if there is already a working prototype available. No need in redesigning the wheel. If anyone can share the details or direct me to someone i can order them from it would be appreciated.

Thanks man I got the brackets and I believe everything else needed for the swap as well. Only thing Im not sure of is the crank pulley. Can I use the original cobra lower pulley or do I have to get the marauder swap crank pulley such as these

Those swap pulleys in the ebay listing are to add boost depending on size of lower pulley and will spin the blower faster, but are listed in the eaton swap thread. I'm not sure if the cobra stock lower fits, but you have a cobra motor says first post so what are your goals for hp?

[decipha]

I have none really. The car is just a driver so hp is no concern. I just want to be sure I can use what I have so the car is not down waiting on parts. On the cobra I had a 6 lb lower and a 2.6"? upper IIRC. I was hoping I could reuse that if possible.

I intend on keeping the original cobra balancer on it of that determines the pulley or not Im not sure.

any details would be appreciated.

Spacing wise the same however if I recall, a +6 interferes with something. A few here have had to trim something on just the +4 but my +4 as well as many others here fit fine.

My Trilogy with a 2.8 and +4 was damn near in boost at all times. It got so hot it was cooking the paint off the blower.

I know there are many previous posts that talk about pully combinations and what kind of boost they produce. I think 2lb lower and 3.0 upper =12lbs
