Good choice, it's the softest engine combo left for the Turbo Dodges. That year the 2.2 used the T2 intake, and Mitsubishi turbo. The Mitsu is so small, it will probably realistically make nearly the same power as the '89 2.5 T1. But, it's factored much lower (I forget now what it's factored HP is). Plus the Shadow/Sundance are pretty light. Should be fun...

One more thing, the A413's differential is the weakest link in the entire drivetrain. If the weight difference between both front left & right tires is more than 100 pounds (may vary, but I base this on my experience), only one tire will spin during a burnout. The differential crossshaft will then gaul up and break the retaining pin. When this happens, the shaft slips out of the differential and collides into either the cover or the housing. Big mess either way. You have several options:

1. Mopar retaining pin clips. Paul Smith shows the part number and how to install. I currently use these along with having the front end weight balanced. So far so good, but I know it's a matter of time before the big "boom". http://www.turbovan.net/Trans3.html

2. Phantom Grip. Never used it, but I've heard pros & cons. Paul Smith's webpage shows it also. If the side gears aren't machined perfectly flat, it will most likely not work.

3. Buy either an OBX or Quaife LSD. These are designed for manual transmissions, but can be made to work with an A413 with a ring gear spacer & cover/housing modifications. Art Leong has excellent details on how to achieve that.

4. The Cadillac option, buy a A413 LSD from Gary Peloquin. A bit spendy, but no mods needed as its a direct bolt in! http://www.peloquins.com/products_A413.html

Good luck.

Just to add - Tim Kish made some spools for the A413 (his Neon runs essentially the same trans with a different bellhousing bolt pattern).
He may still have some available...

Thanks for the info. Ron

Lurking here trying to absorb as much FWD turbo Mopar info and a question comes to mind, are there any other bigger tranny/diff units that can be "modified" to run in the FWD Mopars ? Like out of ? Im just thinking and curious, a later model 6 ? Or SRT4 ? Or.....just thinking.....this was something I was thinking may and have been told is a weak link in the cars , As long as its a Mopar unit its legal right ?

Re: FWD Mopar Stocker

Super secret cam from Autozone. Keep the turbo legal and it will be consistant.
Sorry I haven't posted but I've been busy.

Re: FWD Mopar Stocker

I always ran the stock cam. Car could be very consistent (when and if I left it alone!).
Biggest consistency secrete? Run a stick like I did. Everybody thinks with a turbo you need an auto so you can build the boost while staging. Wrong. That in itself leads to inconsistency as the boost will vary as you try to stage against the brakes. A turbo will go to your pre-determined boost as soon as you side step the clutch. Instantly.
Stiff front shocks. I ran Koni "sport" with adjustable knob on top (still drove it on the street).
My Shelby had the Getrag trans. Never had a problem internally. Once I went to a lite aluminum flywheel and the stiff Koni's I never had a problem with trans axles.
Too much fuel is better than not enough!
I always ran C-16 and 20-22 #'s of boost using the factory inter-cooler. Man, I always wanted to try an aftermarket inter-cooler...it would have helped a bunch!

Re: FWD Mopar Stocker

I really appreciate all the info and please keep it coming. I am hoping to get to do some testing next month. Thanks Ron

Re: FWD Mopar Stocker

Is it just me or are these Mopars the "gateway drug" for Stock racers lol...
