Well I was planning on putting a torquestorm supercharger on my 5.3 and then my brother starts to talk about doing a lsa supercharger on instead.
This company http://www.okw-inc.com/Products.html seems like it has everything I need as far as adapters for the lsa to 5.3 plus for it to fit on my truck accessories.

The torqstorm kit will cost me 2850 shipped to me. Think the lsa could be done for less? I feel the lsa will be a better upgrade because the torqstorm is only rated for around 600 horse where I should be able to make more if I wanted to on the lsa.
​​​​​ I have searched for a while and info seems to be hit or miss and only partial.
What's everyone's opinions on this?

 

Sorry to sound like a dick, but an LSA on a 5.3 is a real bonehead move. That's a rectangular port and 5.3's can only accept cathedral. The one exception to this is if you use one of those funky cathedral to rectangular adapters. At that point you are better off building a 6.0 with ls3 or lsa heads and just being done with it.

 

I completely understand where you're coming from but from a money point of view, definitely not better off. A 5.3 is 4 to 600$ I can't touch a 6.0 for anything under 15 1600. Not to mention I'm sure the heads for the 6.0 are exactly cheap.

The torqstorm supercharger on the 5.3 with a decent cam should meet my 4 to 500 horse power goals. However like I said that's all it will support and thats 2850 in a lump sum. I can by the lsa build in parts if I needed to and maybe one day I can find a sweet deal on a 6.0 but right now I cannot.

Honestly I think doing the lsa swap is gonna be a pain and I'm not even sure it would fit under the hood of my lemans. Just thought I'd throw out the option on doing one vs what I thought I was going to do

 

Where are you in the country. I find 6.0 for 1/3 that price often. My buddy has 4 sitting in his back yard ready to become 408's. I think he charges like 4K for a 408 with ls3 cnc heads and arp hardware lol. It's stupid cheap as far as I'm concerned. That's what friends are for. I got my 6.0 for 400. Got new rods and pistons with ls3 heads. It's either turbo or zl1 blower. Depending how hard ur is to sell my kit.

 

God damn 400 bucks for a 6.0. I'm in northeastern Ohio. Brother works at a salvage yard and his best price for me was 1400 bucks. They sell them all day long for 1600 up. Ls1's are retarded money up here and 6.0's are getting to be bad as well. That's why I said about the 5.3. **** my price for a 5.3 with around 100k miles full harness, ecm and accessories is 500 bucks.

 

I think I'm just going to pass on the lsa. Lol I like the idea of the turbo but I don't think I want to go through all of that again. I did do a turbo setup on my 87 trans am. I do have more room I this car though. Not really sure how cheap I could build a turbo setup for this thing though. Ughh I was pretty sure I was going with the torqstorm but I guess I'm not as sure as I thought lol. If I go supercharger that's definitely the way I'm going but who knows at this point

 

If you have a buddy with a welder, the turbo can be done pretty cheap.

 

Yea, the biggest thing holding me back is knowing someone who could fab the hotside. I might be able to get away using the cxracing thirdgen ls swap headers and maybe hotside. My bet is I could save myself at least 1000$$. So 2850$ for a bolt on kit or get dirty and save some money. There's more than enough people here to help me with what to use and where to buy for a budget turbo setup.

 

Holley has a relatively inexpensive cast iron log system. Pretty sure it will fit 3rd gens...

Speed engineering has a set of log style ones that might work. Doesn't need to fit a third gen. My car is a 68 lemans. Maybe I'll wait and see how the motor sits in the car before I decide for sure. I'd like to see how all the truck accessories fit in. I plan on running the sbc adapter plates. Might spend the extra few bucks and the the adjustable on from speed engineering.

 

This is blatant lie.

 

Where are you finding these? I've been looking for a couple of weeks and can't find any that low. What about 6.2?
