4.3 compressor bracket

So my buddy that tuned my blazer has been talkin a while and gettin parts together to swap his s10 and he has already made his own accessory brackets for alternator and powersteering and i mentioned making a bracket to use the stock 4.3 compressor and original lines and this is what he came up with.

these are the brackets he already has done. uses a jeep powersteering pump that requires a remote resevior. this 5.3 is obivously in a jeep xj but the brackets will clear in a s10



this is the compressor mount. there will be a block that goes between the 2 plates and replaces the spacer that the compressor mount will bolt to.


he was thinking of selling these if theres enough interest in them. there isnt a final product yet so i dont know when we can have one ready or what the price will be. we can also powdercoat them in any color that you want. so if we were to offer to make these how many of you guys would be interested in one?

Re: 4.3 compressor bracket

I was talking to a buddy about this last night. If someone produced a bracket that placed the stock compressor in about the same location and stock lines could be used, i think there would be a lot of interest. That means someone could do the swap without opening the system.

Isn't that what Holley makes?

Or are you talking about the other style A/C bracket that they used on some years?

Also make it for Sanden compressors now

Re: 4.3 compressor bracket

I think it's a great idea, I just wish I wasnt so far down the rabbit hole, I dont need one, now.

Come up with something that maybe uses a 5.3 truck bracket to hold the power stearing pump, mount the 4.3 compressor to the top where the 5.3 alternator used to be, and make a bracket to mount the 4.3 alternator to the passanger side, and sell it for under $500, I bet it would sell like hotcakes.

I was talking about the 96 and up style compressor, however the holley bracket is a great option for the older r4 style compressors

Re: 4.3 compressor bracket

the holley setups still place the compressor on the passenger side, and dont work with the stock 4.3 compressor. keeping the compressor on the drivers side allows the use of the stock lines, depending on condenser i guess.

Re: 4.3 compressor bracket

Oic I thought that was what he meant but the bolt holes in the middle of the bracket threw me off. It didn't look like they would fit but it might be looking that way to me because of the different size pics. It is an excellent idea as long as the high pressure line is still long enough.

Re: 4.3 compressor bracket

There will be another block that goes between the 2 plates of the alt brackets and replaces the spacers. It will be drilled and tapped for the compressor mount to bolt to. It will work with all the stock lines so you won't have to have any custom lines made or have to pay to go get it charged up.

Re: 4.3 compressor bracket

Yep that will work great for folks who have their condenser in the stock location. Mine is in front of core support so I could probably get parts from trans air to make a small extension for my high pressure lines. If it is budget friendly for all the bracketry, it would be very cool.

Re: 4.3 compressor bracket

I'm sure we could make it as budget friendly as possible. My condenser is on the front and his will be too so I don't think there will be any issues with the stock lines. They're soft aluminum so if they need rerouted a little it won't be a big deal. Putting the condenser on the front is only moving it forward maybe 1-1.5"

Yeah, I keep having a brain fart that others have different stuff than I do. I even looked at the pics, and still THOUGHT it was on the passenger side

Re: 4.3 compressor bracket

Yeah those Holley brackets will probably work with the old style compressor. Tbi 4.3s I think. But we're going to make this bracket to work with the new Vortec 4.3 and all the stock lines. Probably wouldn't be too hard to make a mount for a 2.2 compressor. They're mounted in the same place aren't they?

Re: 4.3 compressor bracket

It all mounts with the brackets shown in the first pic. Instead of the spacers between the two plates there will be a block that's tapped for the compressor bracket to bolt to. I asked him the other day about what price he was thinkin and he wasn't sure. Maybe around $500 for the whole setup but he wasn't for sure. He hasn't priced out all the material and all that. The compressor mount isn't finished yet. I'm sure if I can get a few guys to commit to buying it he can get the price down a little. He can also powdercoat for extra too. I'll talk to him more a out it soon. They just got the dyno fixed so ill be takin my blazer back down there soon.

Re: 4.3 compressor bracket

Bumping for update. Has he thought about just milling the factory a/c bracket and figuring out a way to mount it to the LSx instead of creating one out of billet? Seems like it'd be a lot more cost effective and quicker to go that route. I've got a couple laying around I could donate to the cause. (READ: I NEED ONE BAD!!!)

*EDIT* the Holley a/c bracket is just a modified TBI R4 a/c compressor bracket. Someone on a malibu / el camino site has a full write up on how to mod it to make it work. Think the only problem 2nd gens would have running that bracket is the ECM / coolant reservoir.

Re: 4.3 compressor bracket

Of possibly all angles
And it uses a jeep ps pump
Capable of handling a hydro boost?

Re: 4.3 compressor bracket

Yeah that bracket on Malibu racing would be perfect for a 1st gen.
I'm sure you could reuse a stock 2nd gen stock bracket cut down but it would probably be as much work modifying it than to draw up a complete one and cut it out. I dunno I'm not the one making it but he's going to do it out of billet since he water jet the rest of the accessy setup. He was working on it the other day when we got done on the dyno. I'll have to see if its all done or what. Yeah jeep pump that doesn't have the reservoir on it, truck/4.3 alternator. There's a bunch of aftermarket ones too. It's what I use on my racecar. I doubt it would have a problem running hydroboost


I'll check later this week and see how far along he is. Maybe if a few of you guys would commit to one it could get the material cost down a little...

Re: 4.3 compressor bracket

Yes 2 pieces. Belt alignment is all figured in and not adjustable. The lower piece takes place of 3 spacers shown in the first pic then the mount bolts to it.

Re: 4.3 compressor bracket

Any concern with the strength of the piece where it transitions from the horizontal mounting part to where the compressor mounts, possibly cracking in that area?
Other than that, it looks really nice!

Re: 4.3 compressor bracket

Not sure of exactly where you're talkin about but I doubt there will be any issues. That billet is pretty strong. He'll run it on his truck for a while to test it out once its done before he sells any.

Re: 4.3 compressor bracket

It does look good, but has he looked @ vortec brackets? I'm sure he could knock one of them down to mimic exactly what he did and not burn up all that milling time.

Re: 4.3 compressor bracket

If your buddy is serious about making these I might be able to help out. Between the waterjet and press brake I figure you could make one of those pretty easy with less material and pieces, with a little millwork to finish...

Plus I think that's the same buddy who does your tuning right? I need some of that lol

Re: 4.3 compressor bracket

Alright. Talks to my buddy again keep in mind he's just building his for himself and I'm the one pushing him to get it done and make more for other people to use. So he's got got the bracket done and cut out as seen in the last pics. All he needs to do is fit it in the jeep since its all we have available with his bracket setup on right now and get the belt alignment perfected and the 2 bolt holes to fasten the compressor bracket to the spacer drilled out.

What I need to know is how many people are seriously interested in getting one. If I can get a few guys committed to one I can get serious about this and start getting some done.

If I can't get a few commitments then it won't be worth it and he will use the one bracket on his truck and it'll be done and that's it. We're not tryin to make a killing on selling these brackets just figured I'd share it with the lsx s10 community to give everyone else another option to make these swaps a little easier.

Let me know you're feedback guys. Thanks

Re: 4.3 compressor bracket

I can't swing that billet piece and not have a solution for the alt/ps pump as well. That's why I was pushing for modifying a stock bracket.

I'm notching the frame and using stock silverado compressor.

Re: 4.3 compressor bracket

Do whatever you need to do. There's nothing wrong with the silverado compressor. Either way you're gonna need custom brackets or custom lines. He mentioned something about when the bracket is done he could mold it and start casting them. It would greatly reduce the cost. More on that once he gets it all closer to being done.

Re: 4.3 compressor bracket

Went ahead and pulled his engine out of the truck so he could get the bracket test fit. He is going to change it a little and cut down the spacers for the whole setup to line up with a f body balancer. So once it is all done you can use these brackets with the stock 4.3 compressor and lines, won't have to do any notches or recess the radiator forward into the core support. The compressor pulley clears the hood by 2" and the top of the lines is about 1.5" and he still has 1/2" that the compressor can be lowered in the bracket if need be. It's going to need a small notch on the bottom to clear the valve cover.

Coil bracket might need to be modded also
Especially if he lowers mount more

Re: 4.3 compressor bracket

Yeah #1 coil might be in the way a little. Nothin a little work to the bracket won't fix. I don't think it will need lowered anymore with 2" of space to the hood.

Re: 4.3 compressor bracket

Gettin some more brackets cut out so we can test the brackets. Might be throwing them on my blazer for a while since he hasn't even started making the turbo headers for his truck.

Re: 4.3 compressor bracket

Any ideas on pricing yet? Looks like price could get pretty high really quick. Great solution though, im watching closely! I had a very similar idea, but instead of using the milled piece having the front and rear plate come up higher and having 2 3/4" thick rails run back that are notched to bolt between the plates similar to how you mounted yours that the compressor would bolt to .

Re: 4.3 compressor bracket

Not yet. He's still working on it. The billet can get pricey really quick that's for sure. I think he said the 2 pieces for the compressor bracket were 150. Once it's done he's gonna mold and have that piece cast to keep the cost down.
