Easy, use a tailors tape measure and multiply by 1.0053 (correction factor for belt thickness) and it will get you as close as you can get without actually trying a belt.

Nice to see more LSA swaps so that I can get ideas from.

No

Take an old long belt and cut it so its a strap. Route it and mark where the overlap ends. Repeat with the tensioner at full compression. AVG the two measurements and compare to the chart. Bias towards a slightly shorter belt than the calculated number

The correction would change based on the number of pulleys and which direction the belt landed on it. Since this is a universal application, its better to just measure it

LSXConcepts

Yes, that works fine if you have a belt to cut up that is long enough, but if you use a tailors tape measure and take the measurement and multiply the value by 1.0053 it will compensate the value from the inside of the belt to the outside of the belt. that calculation will get you closer than 1/32 (.031) of the actual belt size.

Well finally was able to install mine. Still need injectors though. As well as bolting up the alternator and power steering.

I wanted to post up some pictures of the arrangement I came up with.

I started with 2010+ camaro accessories, water pump and balancer. I wanted to use LSA pullies, so here is how it came together.

I made this bracket out of 1/2 6061 aluminum, which uses the top bosses of the water pump.




I mounted it to the water pump, and spaced the pullies correctly.




I did have to grind these bosses down flat. Originally, I was going to use shims, but I couldn't get the thickness exact.





Giving me this belt arrangement




And the Zl1 lid clears the cowl. Perfect.




I did have to cut an access hole to get to the rear bolts of the cover, so I made a plate for it.







And I had to notch the frame to fit the low-mount AC

Well to start off you'd need the cathedral to square port adapters. Then you'd need to figure out a way to run the pulleys there's one person I only know that offers them to work with ls1 accessories but im not sure if he is a member on here pm me if you want his info.

drseabo

i seen the adapters on ebay for fairly cheap .... if i can work it out ill start gathering... and yes please send me his info

Is anyone pinning the balancer to the crank ? If so what is your approach ? Thanks , JOHN

I put two. It is an absolute must.

I used a kit from SLP, I think? Someone gave it to me. They are pretty pricey at about $75.

If I had to do it without the kit, I would probably just do it by hand. Get a good 1/4 inch drill bit, and some pins, and just free-hand it. I don't think the guide added much support.

Got a kit from eBay. I personally wouldn't risk drilling my crank without the fixture. It comes with two pins but IMO only one is needed. I plan on selling mine with the extra pin when I'm done.

I would think having 2 pins vs. 1 would help in keeping it in balance. Maybe not. lol.

Symmetry. Balance. Feng Shui. 5 extra minutes worth of work.

The material you remove is replaced by the pin. One pin or 10 pins, balance isnt affected enough to matter

casias

I agree. I didn't do it for balance or symmetry. I'm not even convinced two pins is better than one. I just had two pins and wanted to practice drilling holes. HA!

Let me pick yalls brain. I have read through this thread and many others for the last 3 months. I have a lsa on my 08 sierra. I ended up using a modified lsa fead. Has anyone modified the truck compressor bracket to work on the corvette spacing?

Its quite a bit off. Easier to use a LSA compressor and bracket. They use the same peanut ports as a truck compressor, so the lines should work with a bend or two

i have a 2002 Camaro z28 and a 2012 ctsv. I wanted to do this swap myself for the Camaro. I have read through this entire thread and have not found a definitive answer on "lsa swap not ls9". is there a kit I can use for just the pullies? can lsa pulley setup work on these cars ? I also want to do this on a 347ci which was originally ls1. I have seen the adapter plate for cathedral to square port but have a hard time figuring out how the blower would bolt on to the adapters? thanbks everyone and anyone for any input
