New member here. Recently purchased 02 Z. Trying decide if I want to upgrade internals, add cam and SC along with upgraded trans, or let MTI Racing install 403 ci LS3 NA with LS7 clutch. Not sure about cost and HP with SC route but I do know MTI route will be 500 RWP and cost around 12k. And they keep my perfect running LS6 with 78k miles. I love a SC as I have one on my Tundra. Car will not be tracked or raced. I just want more power along with a fresh motor and trans. I just don't know if MTI is the way to go. Any thoughts or suggestions.

 

12k for 500rwhp? PASS!

 

holy **** $12,000? Straight highway robbery.

 

*laughable

 

Yea. That's 12K and they keep my LS6 that's worth what, maybe 3K. So it actually comes to 15K+. Think I'm just gonna beef up internals and install good cam/blower combo and isntall better clutch. Does anyone know of any good head shops around the south MS area? Guess it doesn't really matter. I can just pull the heads and send them to whoever.

 

For 12K, I hope they at least offer a reach around and buy you dinner first.

 

If I were you I'd do the SC first and see if I was happy there. Buy a used A&A or ECS kit off this forum and have it installed and tuned. You'll be in the $6k neighborhood and maybe 550whp depending on kit/pulleys. Don't bother with a new engine or a rebuild unless yours is dead - add boost and beat on it, then rebuild it after it dies!

 

not gonna get 3k for a used LS6 long block....not gonna happen.

 

I just threw the 3K out there. Don't really know what it's worth. I was just pointing out the cost was around 12K plus the value of the motor whatever that is.

 

Just add a SC kit upgrade when needed!

 

I did this, it ain't cheap no matter how you do it unless you do the work.I'm not sure the 12k number is high if it stays at that for someone else doing the work and putting in a high performance ls3 (500rwhp) all done with a clutch. JMHO

 

I've decided to go wth A&A SC, good exhaust, upgrade clutch, and might add meth. And probably a couple more items. Need to decide which exhaust I want to go with. Don't want to spend a whole lot as the car will be occasional driver and won't be tracked but don't want junk. I want it to sound good. Not too loud. Any suggestions are greatly appreciated. Bowtie Automotive in Kenner LA is only an hour south of me and from what I've read they are really good. I'm ready to get this project underway.

 

Just ask them then.

 

I've got a couple of questions for those in the know. What's a good cam/A&A SC combo for the street. Just looking for something easy to drive. Will the venom II CAI work ok with this SC? I've decided to go with ARH headers but haven't picked out mufflers yet. Just want it to sound good. Not too loud. I need to order new valve springs. Was thinking about comp dual spring package. Need to find out which one will work best. Any suggestions would be great. I'm sorry for being so ignorant but I just don't know. You guys know a lot more than I ever will.

 

Oh yea. Since it will be an occasional street car, what should I do about the clutch? I know it will have to be upgraded but don't know the best route for my setup. Thanks

 

How much miles you put on it so far, is it slow? Have you found its weak points? Currently it just sounds like you just want to through money at it

 

That's being polite...

 

I just got off the phone with Hobart, and got him all squared away. He just needed some coaching from the best Supercharger company in the business. He is going to love the boost!

 

'Way late, but maybe you haven't committed yet... what's your goal? Why do you wanna swap out a perfectly running LS6 and install an LS7 clutch, too?

"Fresh motor and trans"... which is going out? I bring this all up (late) because ifn you haven't stepped into it yet, you might have a chance to do more research. $12K sounds about right if that's an LS7 clutch installed behind the 403, labor all in for a turnkey. Not sure I'd recommend it though.

I researched for almost a year; I probably had an easy 120 hours reading just about tuning, N/A, SC, and UPP. My goal was "more rwhp" up to the point of having to reinforce/replace the transmission and/or the differential.

In the end, I decided against it all. Location, location, location. You're in Hburg; I'm in Purvis. Ain't nobody "REPUTABLE" near here with a touted national reputation for tuning 'Vettes. I just couldn't find anyone with more than incidental testimonies about great results on dyno tunes. Fortunately, I started my search after Lethal Racing closed up; they were the closest to us and left LOTS of guys in the lurch in their wake. There are two speed shops that have "decent" reps but not a lot of enthusiastic feedback-- Ragin', and Futral.

Lastly, from all my research, the 'common' ante for SC seems to be around $6-7000 depending on the options one chooses. The "accessories" mount up-- $1,500-2k for installation alone--not including headers, larger intercooler, meth, gaskets, better suitable springs, etc., etc. In the end, without labor I figure I needed at least $9k to commit to an SC conversion. Instead, I decided to go with a Lwt. flywheel, 4.10's, headers, and a clutch (because it was due); the flywheel and 4.10's were just because the clutch was R&R'd at the same time and labor was redundant.

Maybe it's something you might want to consider.

 

He already went with our A&A SC kit, headers, and having Darren Blanchard do the install and tuning.
