V6 swaps anyone?

[Darkapollo]

So I dont own any V6 dodges, but i have been thinking of a really funky set up as of late. Last night as I was driving home from work in my moms van (98 T&C LXi Van with the 3.8 (she is letting me borrow it till the shadow is legally on the road)) I got the thought of swapping that torquemonster into a late V6 daytona. The thing has enough torque to burn off the tires in the van across an intersection (.. no.. i really.. have NEVER done that.. to know for sure...) and that is in a heavy arse van.
I wonder what it could do in a 'lighter' G-body.. Has anyone ever thought of it? if not the 3.8 maybe the 3.3? could it be done (i know.. with $$ anything can be done.. blahblahblah) REASONABLY cheap?

Chrysler put the 3.3/3.8 into the AC/AY body K-based cars and of course the minivans
So In theory the engine/tranny should fit right into a G body I would think ?

But I'm not sure about the mounts and the wiring harness will be a nightmare to say the least

A 3.3 or 3.8 P-body :love: would be cool

[turbovanman²]

It should bolt right in BUT if memory serves, they only got the 4 speed auto so you'll need to rewire for that or run a standalone type setup.

i did a 3.0L with a 604 in my one k car.

1990 caravan harness plugged right onto the factory bulkhead after i moved 2 pins for the windshield wipers.

a later engine (like 98 or something) into an earlier car (like a 90's daytona) will require a little wiring tom-foolery to get it to attach to the bulkhead (or whatnot) and work with the gauges and things like that. earlier engines are easier but they dont have the wallop of the later stuff. using a earlier harness on a later engine would be a tuning nightmare i would imagine.

if you separated enough of the harness, you could use the engine/tranny harness separate from the rest of the car. gauges would be a pain in a car with ecu driven gauges.

in my k car, gauges were easy cause i used a speed sender from the original car dunked in the 90 604 case.

it'd be pretty darn easy if you get a 3.3/3.8 ac/ay as a donor. I've frequently thought about it but decided there was no point since my 3.3 dynasty is already the same weight as a spirit or daytona anyway. btw, it ran 16.2 with a cone filter and extra weight. newe 3.8s have 50 more hp and 60 more lbft plus you can gear down the tranny and put a stock converter from a 413 in for higher stall, and in a lighter car... etc.

[gkcooper]

I am an ex-Chrysler guy and I heard from a guy in development that there were Daytona mules running around Auburn Hills with the 3.3/3.8 5-speed. He said it was very strong. If you can find a 2.7 V6 5 speed tranny, it should bolt up.

[WLKivett]

FYI: Their are about 35 used or remain. 2.7 5 speed manuals on car-parts dot com for sell.

The 5sp's for the 2.7's are not easy to find, but they are out there. But I have yet to hear from anyone who's actually mated the 2.7's 5sp to a 3.3/3.8 to verify that indeed it will work.

However the 3.3/3.8 with a 604 should bolt in place of a 3.0 no problem(other than the wiring, as mentioned already). The 3.0 version of the 604 won't bolt up to a 3.3/3.8, however the 3.3/3.8's 604 is the same externally except for the different bolt pattern to mate the chryco engine. Also, as for motor mounts, the 3.3/3.8 should bolt right in where the 3.0 was, and maybe even be a little smaller because they were pushrod engines and did not use overhead cams. But I think the later 90's 3.8's used a larger intake manifold that may interfere w/ your hood.

You are the ------- man. You really are. I think I talked to you a long time ago in PM's asking if you ever wanted to sell that thing. Well if you ever do, let me know :thumb:

Take that thing to NED one of these summers!

[Aries_Turbo]

naah im not selling it. :) im actually planning on taking the engine and trans out and putting it in my 87 daytona pacifica and putting a 2.5L tbi back into that k car as the k car is getting rusty from the winter that i drove it. i might turbocharge it once in the daytona.

i did take it to the track (NYIRP 12 min from my house) when i first put it together, left it drive and just stood on it and ran a 15.7 @ 87mph. im sure its much faster than that now. with the 5-speed, it rocks. nice and torquey, smooth and fairly quiet.

Brian

[Ondonti]

too bad once you install the nasty factory harness, it doesnt look so clean :(

[Aries_Turbo]

yeah i know. it looks like a bundle of snakes then.

im planning on getting a 89 3-speed harness so it doesnt have all the insane amount of wiring like the 604-harness has. plus rob did that well-defined code for the 89.

Brian

[gti_7]

i always thought it would be cool to do something like that -mitsu v6 in a K, or to do something with that 4.6 dohc v8 motor ford put in their fwd lincoln's.. i know its a ford motor, but the wow factor would be neat to have 280hp 285 ft-lbs of na v8 power at your disposal :)

Neat idea in theory, but then you might as well go RWD and put a mopar small block under the hood. More WOW factor and a lot more fun to drive. Plus the required parts for the rwd conversion of a daytona are avaialable.

What code? :confused: :eyebrows:

[Aries_Turbo]

Simon, 89 3.0L V6 code. fairly well defined. should be out there somewhere.

Brian

[Darkapollo]

just looked at the engine specs on allpar, the 3.8 only makes a dainty 150hp 213lb/ft in '93 O_o
The T1 engine made more hp than that...

[Big_P]

Yeah but not that kind of torque.

Look at the specs for an 03 or something.

[Aries_Turbo]

the high torque 2.5L did make that kind of torque.

the 3.8L i have is the 215hp 245tq version. 2001 caravan. maybe ill put that in my daytona instead of my 3.0L.

Brian

[inmyshadow]

I always wanted to do a mitsu 2.5 V6 swap. The motor is 160hp and is suppose to bolt to an A543 transimisson.

That was until I started reading what the avenger crowd started doing. The are swapping in mitsu 3.0s, 3.5s and 3.8s into avengers and eclispes.

Then this dude showed up

According to sean dalton, that motor is a turd. Guaranteed to run slower then a 12 valve.
the 2.5L has no torque and then also cant breath in the high rpms. lol.

Those 24v sohc heads just arn't great.

They sell 3.5 and 3.8L DOHC and also a 3.8L 24v sohc mivec head that flows 360cfm with minor port work on stock valves. People have done 300 at the wheels (not crank) on the 3.8 mivec with a few mods. Imagine boost.
3.3L dodge probably has more chances of 300hp then a weakened 3.8L dodge :P

3.8L mitsu annihilates the dodge pushrod and it actually bolts up to the a543.

I want to get the AWD working for us so that we have a good platform to bother usign all that power/torque in.

Holy crap. 3.8L turbocharged variable cam timing motor with 9000 rpm capabilities and AWD in one of our light K based cars.

[Vigo]

3.8 mitsu annihilates 3.8 dodge in many many ways.

1. MUCH harder to find
2. more expensive
3. less reliable (too many 200+k 3.3/3.8 minivans on the road to argue this)
4. harder to work on
5. much bigger/more cramped in engine bay
6. must fabricate mounts
7.slightly more stock power
8. vastly more power potential on stock parts


honestly, if you compare the highest non-mivec ratings (cuz even if a mivec head v6 fits under the hood...... you cant run it without work and higher cost$$) of the mitsu and dodge 3.8s, its not too far apart.

i think its apples to oranges. I know the mitsu has much higher potential, but for all intents and purposes its not any easier and probably harder than the dohc 6g72 swap that everyone asks about and hardly anyone has done. As a practical matter i think the low cost and relative ease of swapping the dodge motor will find more takers in an audience like this forum, heh.

the 5spd thing is a big plus, for sure. people here are very anti-604. after a few people build badass 604 cars, everyone will jump bandwagons like they were never on the last one but for now... the 543 ease is probly the biggest plus for turbo-dodge people who have no preexisting v6 loyalties.

[Aries_Turbo]

id love to mate my 3.8L with the T850 from a stratus r/t 2.7L. that would be pretty fun.

Brian

[Shadow24]

there are a lot of motors that can be bolted up to the dodge 3.0 drivetrain. ANY 6G7x motor (2.5/3.0/3.5/3.8) even other ones such as the hyundai tiburon 2.7 are supposed to bolt to the trans as well.

there will probably be fitment issues with the 3.5/3.8 as they have taller decks and the MIVEC heads are bigger than the normal 24v SOHC heads. no one (that i know of) has done anything with swapping the 3.8 for a few reasons ATM such as: Cost, drive by wire throttle, returnless fuel system to name a few.

I personally stayed with the 3.0 because it is oversquare, with a VERY strong bottom end and can potentially rev to high heaven. With a supercharger project in the initial stages, there is a lot of potential in the 24v 3.0. Currently im spinning to 7000rpms and putting down close to 200whp without anything more than a poorly tuned Megasquirt, headers/2.5 exhaust, and a CAI on the motor.

the potential of boosted 6G7x motors in the TD cars is quite high and opens up avenues for more POWER :)

[Aries_Turbo]

and with the awd swaps underway, we may be able to put that power down on the street as well. :)

Brian

[Shadow24]

thats my eventual goal - supercharged 24v 3.0, 5 speed AWD P-body :D

[dodgeshadowchik]

^ just the thought of that is amazing.

:D

[JDAWG]

the 09 i think has a 4.0, not an inline, its the same as 3.3/3.8, 250hp lol

[Vigo]

no, thats another good idea noone has done, but its not the same as a 3.3/3.8. its based off the old sohc 24v 3.5 dodge, which itself was based on the bottom end dimensions of the 3.3. the 3.5 has a 3.3's stroke and a 3.8's bore.

Anyway those motors (any 3.5/4.0) are a ------- rocking motor compared to the 12 valve 3.0 and 3.3/3.8, and in fact, IF anyone would crack the sbec code for the 3.3/3.8, you could hook it up to 3.3/3.8 electronics and tranny, make a passenger motor mount, and run it. Its a strong stock motor. Uncork a 1st gen 3.5s intake and exhaust and you're already over 230 hp easy. 2nd gens rated 250hp stock with worse exhaust manifolds and a few more rpm. My 97 3.5 intrepid with mods would run stock 4.6 mustangs when it ran right, and the car weighed like 3400 too.
