So I was browsing around zzp and found this:

L36 SS M90 install kit
http://www.zzperformance.com/products1.php?id=382

"The new ZZP L36 SS M90 kit allows you to bolt a GM Gen 3 Eaton M90 supercharger to your Series 2 3800 non-supercharged engine with out the need for all the traditional components and without the extensive labor or special tools."

It's not available yet, but will be.
You also need to get their Intake manifold, Fuel logs, their Modified M90, and their custom pulley. I added the prices up and it comes to under $700. And they say they'll install it for $200-300.

Stock gains are said to be 40hp - 40ft/lbs. tq.
Read up. What do you guys think of this? seems like a much cheaper alternative to the $3K+ centrifugal kits (especially if you're not planning on changing out your tranny).

This is definately a very cheap alternative to the centrefugal (sp?) kits, and I'm pretty sure they are testing it on one of their GP's right now. If your looking for big power though, I would definately go with a turbo.

what i'm looking for is a nice power increase without having to worry about the tranny or engine internals (dont have the 3K for the tranny)

Thos is a post from one of the other GP sites.
Found it to be good reading;

Supercharger for the GT Engine and L67 in the GT and SE. (Post #1)
It appears that a lot of forum members want to know if the L67 from a GTP will fit or can be adapted to the GT or SE. Many of you also want to know if the supercharger from a GTP can be placed on the non-supercharged 3.8. The answer to the question of whether an L67 will fit is yes. But you must change the PCM, fuel pump, and will need to put the 4t65e transmission along with a host of other parts to make it work.

As far as putting the supercharger on the non-supercharged engine, it is possible but you need to use the heads, lower intake, PCM and harmonic balancer from the supercharged engine to make it work. You should also change the fuel pump and will need the heavier transmission (4t65e) to handle the power.

I hope this answers the question for those who want to know!

From what I here, with ZZP's kit, all you'll need to worry about is the transmission.

Hard to say.
They are aware you can't just bolt an Eaton S/C to a GT as noted on their page but the kit compensates for the other necessary items? This is a conservative approach, to the point where no PCM tweaking is needed.

Problem is, if you want a smidge more power, that's going to require all the other parts.

I'd still go with a complete turbo kit to be safe.

The ZZP's kit bolts on the Eaton, but with a larger pully making only 5lbs boost. This lets you get away with the higher compression and premium fuel. They say it makes power right on par with the L67. They had a news article on their main page about it that I read. Definately nice that they're offering it... too bad it doesn't help me. :p

im really thinking of going this route. i was originally going to go with teh $3K S/C and run a similar boost amount (5-6lbs) in order to keep my tranny semi-reliable. this is pretty good news to me, i think, because now I can go it for less than a third of the cost!
Then again, if I ever do get a heavy-duty built tranny, I'd probably have to rip it all out. I'd probly be getting a new GP before that, though.

Thanks guys,...and if anyone goes this route let me know!

People always say that supercharging a GT isn't worth it because the tranny will blow. Here's my logic.

People seem to get criticized for supercharging a GT, being told that their tranny WILL blow. Yet everyone is supportive of any other number of mods that will eventually get them the same power. So what is the difference? Why don't people like the idea of supercharging a GT when a nicely modded on will hit the same power gains, but probably cost more?

Chico, ever had a tranny problem, or the need to swap for the "e"?

Chico blew his and got a 4T65E-HD and built it up.
The difference between adding a S/C versus various other mods that will net you the same HP might be torque. A S/C will improve torque as well as HP.
I'm not sure if various mods that will net the same HP as adding a S/C will net the same amount of torque as a S/C.

...what, I think I lost myself on that.

ZZP:
"15. Will my transmission hold up?

The internals of the non-HD transmission are nearly identical to the HD version. The differential is weaker but that is only stressed during launching. Any modification that increases horsepower will increase the stress on transmission components but the stock transmission is fine to around 300 crank HP. The life of your transmission will be affected more by how you drive than by the installation of this kit."


oh yeah, i have 77K miles on me.

HP doesn't kill transmissions...
Torque is the real killer.

I suspect the installation of this kit will affect the way you drive

Later eh!

Slapping on a supercharger or turbo on the GT’s tranny will shorten the life of the tranny. But its not just going to explode once you hit the gas pedal. The main variable is the person’s driving. If you don’t abuse it, I think it will be ok for a while.

One person with a turbo with no intercooler is still using his original tranny. Hear similar ‘original tranny still going’ stories. However, I’ve heard two cases of people with light mods who baby their car but had to do a tranny rebuild.

My conclusion is:
If ( Drag Race = No ) and (Risk tolerance = moderate ) Then keep tranny.
If (Drag Race = Yes ) or (Risk tolerance = low ) The replace tranny.

One think everyone is leaving out is getting the S/C itself. Good luck at the junk yard. Getting it from Eaton directly is not cheap.
Thoughts?

zzp core is 400. ebay had alot of them for 200-350

Pector55? He also does some major burnouts as well... I'm surprised it hasn't burst.

As for Chico's tranny, you have to remember, he's N/A. That means torque is delivered full power to the tranny at even lower RPMs putting additional abuse on it. With a FI engine, torque builds as RPMs rise due to the increase in boost, which puts lets strain on the tranny until it is already moving. In other words, FI is more gentle.

That is the best reply I have heard in weeks.

this webpage seems pretty informative about Horsepower v. Torque....

"Answer: Horsepower is King! (the more horsepower the more torque at the wheel)"

OK here is my take on the SC situation ,the ZZP ASS kit is a well thought out kit with room for lots of potential HP ,and sorry L-67 guys the L-36 with higher compression and lighter internals as well as a better gear ratio makes it a slightly better choice ,but in all things there are pros and cons the trans being one of the cons ,as a daily driver with occasional trips to the track you may be fine if your trans. is in good condition to start with,this is with the base kit at 5psi of boost but we all know that the mod bug bites hard and as you start to get over 300 ft.lbs of tq. your going to have eventual tranny problems .Chico.
