I have a 97 town and country with the 3.8 that I bought this summer. It is my first time using a minivan as a daily drive and I'm sold. Maximum utility appliance of all time, and after blacking out the grill and wheels I even think it looks kinda cool.

Having a minivan maybe a little too utilitarian because I was using the van to gather firewood and blew out reverse trying to back it up a hill to the wood shed. So this got me to thinking that if I am going to swap the trans anyway can I switch to a manual? Is it possible to swap a stick behind this motor? I don't know a whole lot about the 3.8 (and haven't found much after-market help) but I would really like to wake it up a little while I am at it. Up-size exhaust, add cold air intake and a 100hp shot of spray? Or is there a swap to a different motor I should consider?

I'd also like to lower this thing below nose bleed height and stiffen up the suspension a bit. Out back I can change the leaf spring mount, shorten the shackle a little and get the leaf de-arched. Up front I am less sure how to go. Are there any junk yard struts, sway bars or performance mods for this van that anyone knows of? I am also contemplating adding lightness and gutting everything behind the front seats. Some one help me... I was even seeing how much clearance there is between the sliding door and the rear fender for box flares.

I think you're on to something, but I can't help you in any way other than to wish you luck. I'm still waiting for manufacturers to recognize the untapped potential of the High-Performance Minivan market--for I truly believe that there are untold hundreds of dollars of profits there, available for the taking.

I know daytona struts worked on the earlier vans, stiffens them up and drops at the same time. Not sure on the trans, if it's got the same bellhousing as the 3.0 there are options.

I put a bunch of poly bushings on my 89. Was pretty impressive. I miss that old POS.

Unfortunately, the 3.3/3.8 has a unique bellhousing pattern and no manual trans I'm aware of. 3.0 or 2.4 have mtx in other cars, but that mopar 6 is stuck auto. You would need belhousing adaptor fabbed.

Thanks for the tip on Daytona struts. I'll investigate that a little further.

Thats too bad about the 3.3/3.8 having a unique bellhousing. I wonder how hard a 2.4 and mtx from a turbo neon would be to shoe horn in there.

Does anyone have any idea about the performance potential of the 3.8? My google kung fu hasn't revealed much.

Pretty sure 2.4 was available in that generation of van. Should drop in. Somebody has to have already done a SRT-4 swap.

All you need is a DOHC 6g72 out of a Stealth/3kGT. They come with turbos. Who DOESNT want a TT Minivan!

SRT swap's been done a few times. It's fairly awesome.

Maybe check overseas if there was a 3.3/3.8 in one of their yards that has a 5-speed? I know they were sold in the UK and other markets.

Otherwise, yeah a SRT-4/PT Cruiser Turbo swap would yield you something better than nitrous, boost! Of course boost + nitrous = mo' betta.

Exactly. Why have one power adder when you can have ALL the power adders?

Then dig up the AWD goodies.... TT AWD minivan....then N20 on top of that.

I've been perusing the classifieds for a rolled 3kgt for that very reason. They made some of those vans in AWD, so unless the pan changes, there should be a tunnel and room for the rear end.......

From what I can make out, if you want a 5-speed minivan your options are as follows:

Early Caravan 4-cyl

1g Honda Oddessy 4-cyl with accord or Prelude trans

Astro with S10 trans (RWD minivan hoonage? Yes please!)

I don't know that you can bolt the 3.0 into the vans that came with the Chryco 3.3/3.8 as the 3.0 was used on the older platform.

Though if you could do that, then perhaps go whole hog with a Mitsu 3.8 DOHC from one of their trucks with the TT bits tacked on.

Those would be better than the hamstrung POS solution that Chryco dumped onto the 4-speed auto. They just needed to add a couple of limited slips and it would have actually worked. Instead, you lose traction on one front wheel and you only have one wheel drive as the rear drive was driven off the passenger side of the differential, you know the one that is less loaded with one person in the car? Yeah, thanks marketing dorks, thanks a bunch.

3.0 SOHC 6g72 was available through a good portion of the 90's into the early 2000's, IIRC. I wouldn't leave the chrysler slushbox in there anyhow, so if I had some of a 3kgt, some custom shift linkage, and the engine mounts for said 6g72, I'm fairly certain I can make it happen. Ideally, i'd like to find one with the 3.0 out of the box, but that'd be shooting the moon.

Early Astros were offered with stickshift from the factory. Early Aerostars, too

There IS a 5spd that will bolt to the 3.3/3.8, but it's semi-rare.. t-850 from a 5spd 2.7L stratus r/t sedan (ONLY sedan) and sebring convertible (ONLY convertible). Its basically the same box thats in the SRT-4 neons. Which did have a factory quaife.. just sayin.

That body style of van was sold as a manual elsewhere in the world, so a factory pedal setup exists. Getting your hands on it might be something, though.

The shifter is standard neon stuff, except the shifter handle is longer on a van. You can use the shifter out of a 90-94 manual caravan, it's a proper height for minivan use.

You may be able to adapt the older pedal setup, but i never eyeballed that myself. I did have a 96 at one point (and 5 of the 84-95 ones so far) but never looked at that possibility.

The 2.4/3spd auto drivetrain is a factory swap. Just be aware that out of boost, it's going to suck. The 3spd can be built to hold any amount of power, but unless you do it or find an enthusiast to do it, a regular trans shop would probably charge you 2k, do it wrong, and then you'll be pissed. There are several strong 5spds that will bolt to a 2.4, though.

Those would be better than the hamstrung POS solution that Chryco dumped onto the 4-speed auto. They just needed to add a couple of limited slips and it would have actually worked.

Incorrect. The t-case is splined directly onto the diff carrier, so any time EITHER one of the front wheels is moving, it's also sending power to the back.

3.0 SOHC 6g72 was available through a good portion of the 90's into the early 2000's, IIRC. I wouldn't leave the chrysler slushbox in there anyhow,

3.0 ended in '00. Either stock auto (3spd or 4spd) can hold a E36 M3load of power (think 600 hp) if you spend a grand on it. With the 3spd you have to build the internals. With the 4spd you mostly have to drop $700 on an aftermarket controller and run completely stock internals.

The sohc 3.0 is a ridiculously strong motor, btw. It's been pushed to 500+whp on stock pistons, rods, crank etc. The dohc has gone 1500+hp in full race builds but that's pretty irrelevant.

As for using 3k gt parts.. i dont know what you would use or why you would want to. The engine is turned the other way so the trans is out, and the dodge trannies used on the 3.0 are easily some of the strongest FWD transaxles ever made.

Nobody has pushed the 3.3/3.8 very far, so it's weak points are unknown. The main thing it needs to make more power is a cam, a different plenum, and more rpm. But that's more work than putting a turbo on it, honestly.
