I am looking into putting a supercharged ls2 motor in my 92 z28. I understand the different headers and motor mounts and harness that needs to be added to the car to make this setup work. But my bigger question comes in the type of supercharger for this application. I currently own a D1X procharger rebuilt by procharger that I was going to use in the same car but under a 383 SBC. As I understand it it only one company makes a bracket that I can use that would make this charger work on a 3rd gen camaro and after the 3000 for the piping and brackets and a extra 1000 for a fast intake Im not sure this is worth it. Do you guys have any expierence with adding a magnacharger or any other roots style charger onto a 3rd gen. Goal is not a not a track car but street driven amazing car. I believe a roots on a LS2 600 hp isnt really a big stretch but was shooting for close to 700.

The car already has 4l80, roll cage subframes, 4" mufflex, upgraded fuel lines dual intank fuel pump

Since i have a tubular k frame I should be able to just buy the ls motor mount adapters and be done correct

The Ls2 is out of a 2004 denali that I got everything out of.

alot to support the previous set up just no rear yet.

Stepped away from my 3rd gen for a while bought a few 4th gens g-bodies bikes now ready to build a nasty drive to work 3rd gen.

I think a 2004 Denali has the Vortec 6.0L engine, otherwise known as the LQ4.

Basically, you have LS1 Corvette heads with larger chambers and lower compression (317 heads). Easiest path is probably Corvette front end accessory drive and water pump, with a LS1 Corvette supercharger kit. Those are the most plentiful in lightly used condition and the accessories will clear your power steering.

Screw type superchargers for F body are nearly nonexistent because they don't really fit in the car under the cowl. If you get F body accessories then it might take you forever to find a supercharger to match.

^ What he said mostly

If you're on a budget, accessory drive should be chosen after you nab a SC kit because the pulley spacing can fall into three categories: Corvette, fbody, truck. After that match your heads to the blower. There are cathedral ports like you have now and rectangular ports like LS3's use. Some kits like mine are locked in which head it requires, some like magnachargers can swap the intake tub to change head style. If you do that, I will buy the old intake tub from you

A downside to the SBC adapter plates you plan to use is it completely axes any chance to use a low mount AC compressor common on LSx engines

Thanks for the advice I believe I will pick up the supercharger first. I am looking at one now i may go ahead and pick up...One of the big priorities on my list is daily driving and it seems like the roots would be a better no issues daily...I did find one guy he was featured in super chevy that did a roots on a 3rd gen and it looks like there isnt a issue in space. My girlfriend has a 500 so i need to keep all the creature comforts and be faster so AC has to say.

Thank for the offer on yours but may have a line on something thats a better deal... but definitely going to pickup charger then heads...Just need to scour ls1tech for a good deal on low compression heads.

I thought some of the corvette and camaro accessories are similar or is the water pump the only thing they have in common and if so that should mean the accessory spacing should be similar if not the same...

You do have the low compression heads.

Camaro and Corvette have different pulley spacing and the water pump is matched to the pulley spacing. Parts do not interchange. I think you could make a GTO supercharger work with Camaro accessories.

Hes talking about the old LS1 WP that had the huge bell. It was wide enough for both pulleys

Ok.... i get it now... definatly going to buy the supercharger first and then figure it out from there....
Now as far as superchargers... Ive been looking at originally the Magnuson Mp112.... but it seems to have a limitation of about 500hp....next was TVS2300.. seems a little costly so ill put that as last resort.
It seems like people are making over 600 with the GM chargers ZL1, CTS-v, ZR1 chargers anyone have heard of any major reason not to go the gm route since there factory style chargers are they limited vs the aftermarket Magnuson, whipple edelbrock chargers.
Seems like if i want to save a little money but sacrafice a little hp the factory chargers are the way to go just a little surprised that aren't more of this combination out there.

MP112 is just too small for a 6.0L LS engine. It might be a small block but the heads flow more air than a lot of big block heads.

TVS 1900 is a baby blower too. That's what came on a lot of the GM engines. TVS 2300 is more "right sized" for a 6.0L and came on some higher end GM cars. Personally, if I was going to spend thousands of dollars on a supercharger then I'd do it right and do it once with a 2300. It can take you up to 800 Hp.

You'll get more help at a truck forum then about anywhere else. Those people go to superchargers a lot when they want to play. Try the truck forum that is linked to LS1tech.com

OEM kits are nearly as much as aftermarket when all the odds and ends are added in, plus the unique FEAD

A used maggy kit is about as cheap as it gets. TVS 2300 or go home. A twin screw kit will get you there too if you can find/afford one

Dont forget the other supporting parts like a hobbs switch and meth for big power blowers

Think im just going to wait and to see if I can find a good deal on a TVS2300... I figured Ill just build the motor with what i want and just need to buy all the other stuff to support the setup .. which should keep my checking account busy for some time. Hopefully Ill pick up the motor and start pulling things off next weekend.. Im probably going to run nitrous as a cooler since i already own a full nitrous kit and two tanks from the previous configuration... Ill use one for nitrous and the other for air for the air ride.

Nitrous is good for racing, but falls short for street duty. Methanol is an octane booster which helps against detonation. Nitrous just crams more air in there and runs out much faster

Just curious what sort of budget you have for this conversion? Building then engine, supercharging it, plus the swap in general, plus air ride... Lots of big ticket items

This build is definatly not a budget unlimited but not completely budget restrained. Im lucky enough to make a pretty good living and to not have a wife that to tell me No. My girlfriend drives a GT500 so im lucky...But I plan on gradualy work on the project.

1. Getting motor refreshed to hold supercharger
1A. Sell previous AFR headed 383 motor w/Custom Super Ram intake and D1X Procharger kit and long tube headers(new with Por15 coating)
1B. Sell Stage 2 700R4
2. Get heads ported
3. Set aside budget for purchase of supercharger(preferably gently used)
4. Rebuild of 4l80e transmission
5. Purchase supporting pieces to get LS in motor in car (including headers already own Mufflex exhaust)
6. Getting combination tuned
7. Setup suspension

I have alot of pieces previously purchased for old motor setup and hopefully this will off set cost of project..

Time goal ... motor running by mid summer.... suspension next winter... so its not a short term project based on lots of research and picking up good deals everything doesnt have to be new for me and I plan on doing alot of work myself or with help of friends.

I can cover 1, 3, 5, 6, 7 all in one package a heck of alot cheaper than you could piece it together yourself

Engine, T56, 8.8, driveshaft, tubular rear suspension, tubular K-member, big brake upgrade, harness, tuned PCM, big exhaust, meth, harness, tuned PCM, all the small parts

Ive got several engines available including an alum LS2 if you really want the best

Heck, I can even install the whole thing

I actually had planned on reaching out to you on the wiring harness part anyway i had read your post on the harness that you make... Just am waiting to make sure im going with a 4l80.
Send me a pm on what you have a big brake upgrade selling for (CTS-v 4 piston only matches my other camaro)
Is you can get ahold of a tvs2300... and supporting hardware then we definitely need to talk.
Its not unlimited dollar but spending smart money on the right things for a great DIY build that makes 6-700 hp
