WOW. That certainly was an eye opener. Thanks. That cat put a lot in to that mod. I wish he would have stayed with that a little longer.

Here's the math I did when I bought my used LS.
MSRP: $40,600
Invoice: $37,300
Rebates: $6,000 + $1,000
Your price: $30,300
So a new LS V8 would've been $30,300 assuming you paid invoice and financed through Ford for the extra $1,000 rebate. I don't know if the rebates are still that high now.
Yea...That rear mounted turbo stuff is cool. I saw the Two Guys Garage episode just the other day! That is the first time I actually got to see one, even though I read about them last year. That would be something to look into for the LS. The compression ratio being so high, we need as much power as we can get with as little boost as possible. Turbo baby! I was going to post about this yesterday, but the Nyquil kicked in. Glad you guys beat me to it!
As far as the 3.9 taking 400 hp, I would be surprised if it didn't. Most bottom ends will take that much power, as long as it is a nice even flow and not a sudden shock, and not riding along with detonation. The problem is getting it there in the first place. I would feel better sticking 8 psi on the 3.9 if it was at 9.0:1. Every once in a great while, I get a little detonation in my Mustang and I have it tuned right. I would probably blow a head gasket before anything else on that 302, but on the 3.9... I would probably waste my underwear if I heard detonation.
Also, I would have no problems using the 4.6l. They are not my favorite but they have proven to be reliable engines that can take the abuse I would give it with an LS. I wouldn't trust a stock 4.6l 2 cam with 500hp, but I don't want that much power in my LS. Who wants to replace everything in the drivetrain on a monthly basis? I just want a clean, reliable 300 rwhp. You start talking wild power and you need to think about the driveshaft, mounts, suspension, and other stupid things let alone the transmission, rear-end, and engine. Save the big power for the weekend warrior car that weighs 2800-3000 pounds.
We need a limited slip diff too.

You can always regrind the cams. I would bet nobody's done it yet, though.blk04lse said:

the owner of the LLSOC did re-grind his cams and ported the heads - 36hp gain. had a problem with the heads been cut too deeply and had a water jacket leak.....

Interesting. Not great gains, but he probably had to do alot of guessing as to which cam provide would be best. That guy's a real trail blazer. Did he have any sort of chip or dyno tune to ensure he got the full benefit of his work?

Man that article on the STS turbo is great. I havent bothered to look em up yet though. Does anyone know what they cost?
From reading what I have read so far it sounds like a great system and now that the PCM can be tuned this thing and the might offer up some serious ponies.

A few things...
1. Besides the tire and spare, where can we lose weight w/out deminishing the integrity of the car? On the car, not the driver... ha ha ha
2. $4000 - $5000 + for a supercharger is ridiculous, especialy when you can get a Powerdyne (6 lbs) under $2000 for a 5.0 L Mustang... An option is the pick up a used supercharger head unit, but fabricate the plumbing and brackets.... May want to increase the fuel injector size (if available) and install a fuel pressure regulator...
3. Only 36 hp out of port heads and custom cams???? Man, that is where NMRA Mustang engine builders/modifiers come in like Ed Curtis or Rick Anderson, where they can port and freshen up the heads, and create custom cams that are built to match the flow rate of the heads (they have software that spits out the cam specs based on all of the variables of the moto and setup of the car - they do make emissions legal cams too).
4. Unless I am mistaken, I do not believe there are Stalls out there for this car... Are there steeper rear end gears? Will the 05 GT aftermarket gears fit? And we do not have limited slip?

Not that I know of. I mean you can pull the rear seat out (it's fairly light).
blk04lse said:
The supercharger I am testing should be half that in price.

remember - that was back in the day before we could adjust the tuning.

between $3,700 - $5,000 - without tuning.eL eS said:

hmmm turbo or sc?
Quik LS
Dedicated LVC Member
SC will be eaiser, the turbo has more hp potential. I think either will produce more than we can handle - so I'm going with the easiest to maintain and lowest initial cost....eL eS said:

yeah despite their propaganda about it being safe mounted low and to the rear the jury is still out on the turbo gimmick. Fortuneately or Unfortuneately their is still time to decide.

Not to highjack the thread, but how is the getrag 5sp used in the v6 models? I've been serioiusly considering my next project using a 3.0 v6 5sp LS with a turbo....
I know quite a bit about turbocharging and would very much have been wanting to play with a 24valve 3.0, an awesome motor by any means. I figure a solid 400hp on street gas should be a walk in the park. Anyone know where I can find more info on the manual transmission, as I could not find a search button in the forums.

well - apparently the reason the V8 did not use the 5spd was that it couldn't handle the v8 tourque......

man the LS would look so good running the GT SCCA Circuit. I get sick of seeing the CTSV just lay it down. We need equal representation.
I did read in automotive that the head of SVT, Hu Tang, is looking to start tuning Lincoln and Mercury vehicles. They would not share the SVT name but they do have thier sights set on the luxo brands.

Anyone have a model number for the trans? I can get ford part numbers at work but that doesn't do me much.

5r55n for the 00 and iirc the 01

I was looking more for the manual model number, as I know what the auto is.

there was the one ls (black) that was turbo charged. It ended up blowing after over-boosting (or something). I think it was here on the forum.
