I swear I've seen threads on this, but couldn't find any with my apparent lack of technical prowess with the search function.

04 LS6.....

I have a chance to get a V2 blower for cheap. What would I need to to fit a V2 blower on it?

All I have seen are "tire kickers" on the V2 blower threads. I haven't seen it successfully done yet, so you'd be the pioneer. Don't know if the pulleys would line up, or if you would have to swap over to V2 pulleys, or how much room there is for the HEX or routing piping. Seems like the cheap V2 blowers have created interest in this, but none so far followed through. Good luck, definitely want to see if this is viable.

See if ronr has looked into this. He was a pioneer maggie adopter, and recently replaced his LS6 with an LSA block and even put his old maggie on it. I believe he looked at a few options and may have some insight on it to help out.

The belt routing for the blower is the problem. The V2 blower drive is exactly the same distance from the block as the truck belt, which puts the balancer in the radiator fans.

It can be done, but anything can be done with enough time, money, and rage after you get too far in to quit.

Brian (07CTS-V) is helping someone do the conversion. First off, you need rectangular heads, which means you would need to get small bore heads (more expensive, I believe), and the blower/throttle body don't clear the hood up front. There is room for the pulleys, but you will need a decent hood bulge to fit everything.

If you have an LS2, you can get LS3 heads (821 cast) and then you'd have to pay mind to the brace and to the pulley setup. There'd be more involved, but the first step would be rectangular heads like the LS3. If its an LS6, idk which heads would work.

This dude, thirdgen's, is making cathedral-to-LS3 port adapters from aluminum and phenolic material.

Get the phenolic material...

Geometry isn't my strong suit, but wouldn't you have to mill the blower manifold with spacers?

Looks like it just raises the blower another inch.....perfect. Lol

1/2"

Unless you can score a new v2 sc complete for less than 4000$ this upgrade is almost not worth the trouble

Making it even tighter for under hood space. But what I mean is installing spacers would mean the gap between the heads and manifold is smaller, so wouldn't you need to mill the manifold?
Like when you mill the block it changes the geometry, if you mill lots off you sometimes have to also mill the manifold to fit.
Anyway, for a 1.9l blower it would need to be much less to pay for all the extra parts, and all the work involved. Or getting a 2.3l tvs or eforce seems like a better option to me.
Plus there is a problem with the bearings on the jack shaft, or something, that v2 owners are getting fixed. so you wouldn't want one that has that problem, unless you plan on fixing that.

The blower moves straight up...the attaching bolts go straight down.

I have a LSA s/c that I'm into for 475....i need injectors and a fuel rail.

Plus if y'all read the thread, it states a couple different sizes are available...primarily 1" and 1/2"

Looks like these are on eBay for $200 in Aluminum.

If the guy was smart he factored that geometry into the spacers.

No need to mill. Read the thread...or at least the first two pages.

I've been looking into this option as of recent too! I have an idea for bolting the LSA blower directly to cathedral heads using a special gasket.

hefftone

That might not even be possible due to the funky injector placement. Check out this thread, near bottom page 2.....has some good pics about how the s/c runner goes straight down, then straight down through the adapter plate, and into the heads port.
If you used the plate with a LS3 manifold, it would interupt the flow alot...as the air would flow drop down and turn again....basically making a hard chicane in an N/A.
I also found some similar on ebay for $200 shipped (Aluminum). I don't know if I can resist that....I'm not popping for a set of Trickflows and honestly I don't even want to switch to stock LSA/LS3 heads....if it works out well, then a built iron 5.3 would be a suitable replacement engfine down the road (or in a different vehicle)

Well, ****

The difference in size/shape of the rectangle port and the cathedral port is not much. the cathedral port is slightly skinnier but slightly taller...but not much. I feel like if you had a gasket that would block off that small tiny section right at the top of the cathedral port and would hold boost.... it would allow the use of the LSA blower to the cathedral heads. we're not talking a half inch of blockage... we're talking very small minute area where the cathedral port wouldnt be covered by the rectangle port. I think its doable.

There's a couple people running them. Im having a hard time finding the links. There's a guy that makes aluminum adaptors. I've seen the blowers on ebay for $500 several times. The biggest issue is going to be belt space. But if you want to flip your fans around so they are pusher fans that would make you enough room for belt clearance.
