Thought I'd start a thread about LSx Accessory Drives, and their options.


With the addition of the Gen IV blocks and the 2010 camaro and other models, there are some other options available both OEM and Aftermarket for engine Accessories.

Hopefully, what this thread can cover is how we are all approaching the accessories options with our swap. Here Are some that I've found so far:

1. 98-02 F-body LS1:

11. Camaro PS/Alt/PS with spacers on truck spacing (for VVT)
(found on LS1Tech.com)
Information:
Allows you to keep VVT on engines so equipped. Water Pump Spacers are supposed to be available from Mast Motorsports, though I could not find it on their site.
Alt & PS spacers are .75" aluminum bar stock that was cut to fit. Should be fairly easy to do.

Pros:
-Similar to Camaro in fitiment
-Can retain VVT and Stock Truck Crank Pulley

Cons:
Same as Camaro LS1




12: Gen4 Camaro PS/ALT & Gen5 Camaro Water Pump with spacers
(found on LS1Tech.com)
Information:

Pros:
-Similar to Camaro in fitiment
-Can retain VVT and Stock Truck Crank Pulley


Cons:
-Notched or Tubular K-Member required for AC mounting in stock LSx Location
-Need to have the L99 Tensioner as well due to casting differences
-Requires different upper radiator hose due to different routing at water pump

GTO LS2 requires notched or tubular k-member to accomodate A/C and possibly the alternator as well. Idler arm may hit A/C compressor. I believe it has the same spacing as the F-body, but I'm not sure.

When you say expensive to start with a truck block is it just because you have to buy the complete setup or are there other parts needed? I was looking at the C5 setup on a truck block is the reason I am asking..

Falconiroc

Yes, the reason why it is expensive is that you have to buy the complete setup, as corvette and Truck spacing is different. There are however some people that are using spacers to use other car's accessory drives at the truck spacing. there are only a few reasons why you would want to do it this way though. For instance, if you had a VVT motor and you want to retain VVT.

Great thread idea! I think you mean Gen V for #3 though right? IV is 4th gen.

Pretty sure the GTO LS2 is the same as the LS1...with the only different being the remove power steering reservoir...correct me if Im wrong.

With any of the combos that require notching of the k-member for the a/c, you're going to have to slide the idler arm all the way down, and fiddle with things a little. But it all goes together as this thread suggests.

Its actually rather surprising how well everything fits. I expected way more issues when I started my swap. This will be a great reference for guys finding motors in things other than the f-bodies..

I am running an f-body pump with the spacers. The reason being is that i originally started with a truck motor that i ran a carb on so i built custom PS and ALT brackets to fit the truck pump and balancer. Now i am converting to fuel injection and i didnt want my custom accessory brackets to go to waste.


f-body pump with 3/4 inch spacers


Also tried a gen IV truck water pump but it didnt quite have enough space for the throttle with my edelbrock 90mm. I hear some people get away with notching it like this depending on the brand on throttle body.

Shift06

I believe he meant a Gen 4 engine not a 4th gen engine.

Ah...I saw camaro after it and thought he was saying it was for the Gen IV Camaro. Ah well.

I have seem this mentioned before in other threads. What sort interference is encountered between the idler and a/c comp? Moving the working position by sliding the idler all the way down off-plane from the pitman will change steering articulation and handling. Any pics available?

The nut and stud from the center link can be close to the compressor or the line coming from the compressor depending how things go together for you. At least...this was my experience.

You only have a little bit of adjustment with the idler arm bracket. I dont think it will ever cause any ill handling or adverse effects to your steering. At least on a street car. Maybe on a super precise racing set up where you'd notice tiny changes. Ive had it this way for years and my car out handles me still. I think my idler was about 3/4 of the way up on my 87, and it was right in the middle of my 86. I took note of each so I could at least try to put it back...but ultimately ended up sliding both down all the way.

No pics really. I had read about some guys sliding them down further by slightly notching the slots, but I didnt see any reason to do this.

J.

Ok I lied...found a couple pics. Ignore the messes...most of these are in progress shots from both builds. Here you can see the interference area...



The other reason for me moving it down was to clear my lower hose.



In this picture you can actually see how the center link is slightly tilted. Its not as bad as the pic makes it seem...but as I said, I also havent seen any ill effects. High speed stability is great, cornering is great, everything works perfect.

mwfrels

The second makes it look as though the a/c pulley would be hitting the top of the idler arm as well if not before the the bottom of the compressor would hit the stud/nut at the center link attachment. This is helpful though. I might be able to mock-up something when I am fitting and modifying the crossmember I am going to use.

Thanks,
Mike

ill be swapping in a 5.3 truck motor switched to carb. with the kwik performance brakets for alt power steering and AC.

Ive searched on the kwik performance wed site, do the ps/ac/alt use the stock 91 camaro compresser, pump and alt? or does it use the accessorys off the truck?? (the web site is confusing)


thanks you guys.

Falconiroc

The Kwik stuff uses LSx accessories. The ones you use depend on the kit you buy. they have kits for Corvette, F-bod/GTO/others, and truck. They do not provide a kit where you use your third-gen accessories. You will also run into differences wiring-wise between the third-gen accessories and the LSx accessories.

IMO the better route here would be to use either the truck accessories with the brackets, or buy F-body accessories.

You may also want to consider using the 2011 Camaro water pump with your setup, which will retain the truck accessories spacing but provide you with a water pump that will not interfere with your throttle body/intake. (Keep in mind you will also have to use the 2011 Camaro tensioner)

I bought an L92 I'll be swapping into my 84 camaro. I will be keeping the VVT. I have all the F-body LS1 accessories except the water pump and drive pulley. I'm thinking that the L99 water pump and tensioner from 5th gen will work best, as I need to buy a water pump anyway and then I won't need to buy spacers for an LS1 water pump. Would this be wise, or should I just buy the LS1 F-body water pump and spacers. It will be about the same price.

hicksport

I am swapping in an ly6 truck motor with vvt and using the truck acc. I modified the alt to fit on the pass side and moved the tensioner to the drivers side. Should be in the car in a few weeks, we'll see how it works??!!

jbone

iTrader: (2)

Nice work... keep us updated

Thridgen60

iTrader: (2)

Looks good. Did you just relocate it so it would be mounted lower?

hicksport

Yes the truck alt bracket puts it into the hood from what everyone says, I havent been able to find camaro brackets, so I just started modifing what I had.

hi all,

I think this kit into 3rd gen..

That is the corvette setup.

bigal's1991

I'm doin a 5.3 swap on a tight budget, here is my plan truck accessories with qwik brackets, no AC to start off but it will be in my harness. And use an fbody water pump with spacers(ill be running the ls1 intake) I will try to notch my truck water pump first tho, I'm jus going to use the stock truck thorrtle body.

CTS-V accessorys are shorter (closer to the timing cover) than the GTO/Fbody setups, they match the corvette stuff when it comes to spacing.

jbone

iTrader: (2)

I'm thinking I want to use an L99 water pump on my L92 6.2 with vvt instead of an f body water pump, and then buying spacers. I have all the rest of the 4th gen F body accessories. I see that the plumbing direction for the hoses will be different. Has any one used the L99 water pump with a third gen yet, or does anyone foresee any problems? Thanks.

Falconiroc

The L99 will be more similar to the 4th Gen Camaro routing than the Truck one will be. The truck water pump puts the coolant intake tube at a very steep angle and can interfere with the throttle cam.

jbone

iTrader: (2)

Ok cool. So would the L99 pump and pulley be a better, as good, or worse option than the F-body pump? This will be a throttle by wire.

Falconiroc

Its going to be similar to the F-Body pump, but with the appropriate spacing without spacers. You will need to use the L99 Tensioner too, the Truck tensioner is spaced too too far.

jbone

iTrader: (2)

Ok so no routing issues with the discharge being located different than the F body pump?
