I hope this belongs here. S/C Plans for a 3.0L

[02gcaravan]

Here is what I have and following is what I would like to do in the long term.I'm partial to S/C’s like the Powerdyne and more likely the Eaton M90 or M62. I say the Eaton more likely due to the info I have found related to it's application on several Mopars that I have found.

1995 Plymouth Voyager
3.0L Mitsu Engine
A670 3 Speed Auto Tranny.

I have seen the 3.0L Neon with the Eaton mounted on top of the Plenum and was really intrigued that the blower sat right on top of the Plenum. On the Neon it was a little outrageous due to the amount of room needed, but it was still nice to see that it fit.

Now, some basic questions that I have are listed below. I have done this type of mod before on a Saturn and, well, since then I am driving the Voyager now, that spells out what happened to my Saturn If I only would have added an IC I'd still have it today.

Anyways, with the Saturn I installed a Powerdyne BD600. I had a larger exhaust to help with the increased air intake volume, 2 steps colder plugs to help tame any detonation, and a separate fuel controller for 2 extra injectors I had right before the TB. Everything else was stock.

Now, after some preliminary research around various Mopar forums including "The Dodge Garage" and Turbododge.com, I was wondering the following questions:

1) Would I need extra injectors IF I upgraded the stock injectors to say a Turbo II style?

2) Does the M90 / M62 "really" just bolt on to the Plenum or is there a custom type of bracket that I would need to be made?

3) How much WHP is the stock 3 speed auto tranny good for?

4) How does the TB for the van fit onto the Eaton? Do I need a different type of TB or can the stock one be used?

I've seen the website that has the Lebaron that has a Eaton blower installed BUT, that install was totally custom, IE: The blower was mounted next to the Plenum and the firewall. I've also seen the turbo kit mentioned and listed here at AllPar but like I said earlier, I'm kind of partial to S/C's.

If no one has any answers perhaps does anyone know of someone that I might be able to contact about this? In my searches around the web I've noticed that "some" of the sites have not been updated for a couple years.

Thanks In Advance!

P.S. Is there any one here that lives in the Northern Ohio area that may be able to lend a hand here or there? Specifically with tuning, if I ever get that far with this project.

Hi! I am planning on the same setup you saw.

The Eaton M90 / M62 will bolt to the plenum, but you will have to cut a hole in it. Another member from this board used the throttle body from whatever car it came from. Both throttle bodies were from Holley, and had the same voltage output. You simply make a block-off plate for the throttle body.

The stock 3-speed auto is tough. It's not uncommon for people from this board to put 220, 250 hp through a dead stock transmission. How long it will last like that, is unpredictable.

You would still need extra injectors, even if you did upgrade to TII injectors.

*raises hand* I'm in the Toledo area.

How much boost were you pushing into the Saturn?

On the first dyno run it came out to 6psi but that was not a reliable test, as far as the psi was. That was a gauge estimate. At that point it came out to 158 whp. On my second run, about 2 weeks later, the shop had some type of gauge that they hooked up to the vaccum line itself. This one came to 8 psi.

Supposedly the S/C kit I bought didn't need a IC. It was the charge temp that caused the detonation that killed the lands on two pistons

For while it lasted the 158 whp was fun, especially in a plastic car

The Voyager idea I have is a long term project. That's the only way to keep myself sane at the same time as keeping my wife sane as well.
