So I did a bunch of searching on what possibly could be different between the two and the only thing I can tell is the water pump on the GEN 4 is different but all the bolt holes are in the exact same spot because they have to be. The GEN 4 also uses a 2 bolt tensioner compared to the older 3 bolt design. The 2 bolt design just removes 1 bolt but looks to retain the same spot or area as the older design making fitment almost mint. The pulley stays directly above the thermostat housing neck like the GEN 3 does.

Also your recent pictures also looks to proves it fits. That is a GEN 4 L99 or similar camaro water pump using the same bracket that is on the LQ4 posted in prior pictures.

Nothing else is really different, the crank pulley will fit like normal as it replaces the stocker that is the same from 99-13. What I don't know is they are going to add in the 09+ MAF piece to their charge tube or if that is something that would be required for the user. It's only a 20-25 dollar part that needs to be welded in place after the blow off valve.

I totally understand wanting to confirm an install on your end before adding the kit to get ready for sale. The pictures make it look like it already fits. It's already August now and I'm been thinking about it since last December/January when you talked about new kits and been waiting 3-4 months on confirmation about the 07-13 kits, I'm thinking about ordering the kit for the 99-06 anyway and make it work for me if it came to that.

 

Top is a GEN 3 water pump off a LM7/LQ4 and below is the LC9/LMG etc etc water pump from a GEN 4 5.3.

 

Buy supercharger... or get car painted. That's my dilema right now.

 

Boost will make you smile more.

 

Normally I would agree, but I have been restoring my 72 for 7+ years now. I really need to wrap it up and start enjoying it. It literally needs paint, tires, front end alignment.

 

Paint it next year, drive it this year lol.

 

Never heard of this brand before? do they have more info to read up on?

 

 

I might have to look really close at this for an 03 Hummer H2 (LQ4) when I pull her in the shop to work on a ton of stuff this winter. Bottom end is where the H2's need some extra grunt so I'm digging that this setup really pushes in down in the lower end.

 

If anyone is near the Grand Rapids Mi area, you may have heard of the local cruise/car show, The 28th street metro cruise. Well we are hosting our 5th annual Open house at our new facility this friday the 24th. Come out and see some cool rides, food and drinks provided.
