3.0 to 3.3

[19omni87]

i wanna find out whats all needed to put a 3.3 out of a 93 voyager into a 92 acclaim with 3.0. im thinking everything will botl up being as its same tranny and all. only problem i forsee if that the 3.0 has a distributor and the 3.3 has a coil pack. so im thinking it falls down to engine harness. id have to match the voyager engine bulkhead to my acclaims underdash bulckhead. anyone got any wiring diagrams for that? alright just figured id post on here thanx

um, not sure why you want to pull that off. You will be stuck with an asuxO4 tranny and a crappy engine. Put the 3.3 tb on the 3.0 and they should make about the same power.

The 3.3 4spd auto and the 3.0 4spd auto have different bell housing. That being said why don't you do a 3.8 instead of a 3.3? Or if you are feeling real ambitious a 3.5 mounted transversely. Wiring would be a problem for either....

Why not just build up the 3.0L with a stroked crank? There are kits out there that will allow the 3.0L to become 3.3-3.5L strokers.

But, if you really need to put in a Chrysler 3.3/3.8 motor into your car, then you'll have to get the motor with trans, trans controller (if you don't already have one), complete engine wire harness, PCM, and lots of beer for the work you'll be doing.

Yes, the transmission housings are definately different between the Mitsu built 3.0 and the Chrysler built 3.3-3.8 engines. The PCM setup is entirely different since the 3.3-3.8 use DIS with a crank and cam position sensor (both of which have to work for it to run). I agree with the idea of enlarge the 3.0 engine, but you may have to tweak the engine cal to get enough fuel for the larger displacement. I don't know how much of the 3.5L SOHC 4 valve stuff would work, but that's a real strong engine in the Intrepids etc. The dual throttle bodies might be fun to make work sideways though and the cooling system would be another issue.

way to much work for the small power increas and lack of support. the 3.3/3.8 has no standrad transmissions avalible for them. the tranny as said will nopt bolt up. there would be really no room left. the mounts are a little diffrent. wireing harness diffrent. comp. and the 3.3 plenum might have clearnce issues with the hood. but maybe not. i would just get some stuff and upgrade the 3.0. many of us have and many more will. cant go worng doing something that others can help you with.

Anyone who thinks the a604 tranny is different then the a sux tranny in the 3.3 or 3.8 should not attempt a motor swap.

They are IDENTICAL internally. SAME CRAPPY TRANNY.


the 3.3 and 3.8 are pure crap. The only one I would touch is the newest 3.8, and I would only play with that if I was driving a minivan that was meant for soccer mom/dad. Not in a sedan that is obviously looking for a power upgrade.

when is the last time you saw a semiquick 3.3 or 3.8? The 3.5 chrysler is a whole nother issue and would not work. You would be much better off going 3.5L mitsubishi mated to a chrysler tranny. Geez, the 3.5 mitsu can actually use a tranny besides the a604.

Unless you want to spend $3000 on a performance tranny rebuild for the a604 (and can only be used dragracing, no other racing), this is something that should be rethought.

yeah i actually looked at the engine today. too much bs for a engine with only the horsepower and torque of a 2.5 t1. i did however grab the tranny computer out of the van and probably tommorrow the calipers rotors brake pads and shoes and the tb. the tranny computer bolted right up and works i might add. guess they didnt change the tranny wiring between 3.0 and 3.3

[Moparbishi]

it is the same tranny computer. smae tranny just a diffrent bolt pattern

[capev86]

a 3.8 and a built tranny would be a good idea if you were gonna use the car as a tow vehicle! i'd swap in a mitsu twin turbo 3.0 and use a daytona/shadow 91+ V6 5spd tranny! go all out w/ rt brakes, shelby suspension, etc while you are at it! there is a guy on allpar that is putting a twin turbo 3.0 in his "still auto" non-es 3.0 spirit!

[jonny mopar]

IMO the 3.0 is a better motor then the 3.3. that and they sound better with no muffler HEE HEE. But if you wanna do some work "like it looks like you wanna do 3.0 to 3.3" just get a 3.0 5sp car and rob the trans and all the goodies out of it and put them in your car.

While it would be lots of work to get the 3.3/3.8 to fit, it could work. And you obviously have never driven a 3.8L car. The service station I used to work at was owned by a guy who was also a car flipper. He had in a 3.8L Imperial and I took it out for a drive, and let me tell you, the bottom end power of that thing made my parents 3.0L Dynasty feel like a freaking honda. That 3.8L could pull that larger car from a slow speed much harder than the 3.0 could pull the smaller dynasty, and both were 4sp/od cars. I never have driven a 3.3 though. If I had to choose between the mitsu mill and the all chrysler motor, I'd take the one with more cubes. But it really depends on your HP goals too. While there is a limit of practical hp upgrades you can do to the 3.0 and the 3.3/3.8, if you want to put stupid amounts of money into your engine, the 3.0 has some aftermarket support, where the other's don't. And the 3.8/3.3 is gonna be automatic only, where with the 3.0 you can go 5sp, if you can find a 5sp for a 3.0, which is a big IF. But if I already had a decent running 3.0, I would say it wouldn't be worth the effort to go to a 3.8, unless your 3.0 grenaded on you and you were feeling really ambitious.
