3.0 motors

[ecs]

The K-cars are the ole chrysler/dodge cars of the 80's and early 90's such as the: Aries, Lebaron, Reliant, Spirit, Shadow, Dynasty, Imperial, New Yorker, etc etc.

The particular K-Cars that i'm referring to with quite a bit of engine space is the Lebaron, Spirit, and Shadow. All of which came with the option of a 3.0 IIRC.

Not to mention you'd end up re-wiring the whole car. Also, do you know the components of an AWD system? If you did know... then that would definitely not be fun making it work or having problems with it. I'm not trying to discourage innovation, but it gets to a point where you ask.... is it really worth it?

Another post where you are just making stuff up.

3.0's have been installed in Neons and omni's

Also, most TD guys say the Neon has more room in the engine bay so this making up information stuff is getting very tiring.
You shouldnt tell people what to do if you are just making up your facts or guessing. .

Brent it will be alright...no need to get so mad about it.

replying to an earlier post: the mitsu version of the SOHC 12v has a 10:1 CR.

[jory]

After some searching I found this info on automotive.org, the SOHC Mitsubishi 6g72 has 175 HP @ 5,500 rpm; 185 ft lb @ 3,000 rpm
And the only things that I know are different are the intake, cams, and compression ratio. Is there anything else that the mitsu motors have that ours dont?

[mwinkle353]

Other than the calibration?

[jory]

Yeah the calibration must be better too, so are those the only differences?

[c2xejk]

exhaust manifold is different.

Im not so sure about those numbers. 160crankhp for 3000gt's. Different numbers for different models im sure but I dont think automotive.org is the place to find mitsubishi info.
All the mitsubishi HP numbers seem to have very little relevance to actual power output. I can present examples if needed (even with the same motor during different years).

Most mitsubishi sohc 12valves (as found in 3000gt's) have only 8.9:1 compression (not 8.85 like early 12v chryslers). Apparently some early 1992ish diamantes etc have 10:1 compression and cams with a tiny bit more duration (to match the higher compression).

[jory]

hmm i see... So not all the 12v motors found in mitsubishi cars like the diamante have 10:1 compression and the slightly longer duration cams? I'm not saying the chrysler motor is weak compared to the mitsubishi because mine pulls pretty hard with its 150 horses, just want to know the differences.

the 12v variants had a few flavors depending on the vehicle its in. i think the montero's had a different cam than the vans with a tad more torque. some of the diamante's had the 10:1 12v, there might be a different flavor in other years/trim levels. as brent said, most of the 12v's were more "economical" than their 24v SOHC and DOHC counterparts

the 24v motors are a tight fit in the shadow/duster, see my thread on my swap (search Finished! 24v 3.0l swap, or something like that) to see how much room i have with the SOHC, the DOHC's have bigger heads and the 3.5L has a taller deck height to boot.

montero=chrysler cam.
Montero has an intake manifold that is like a mustang 5.0 that helps with torque.

[DustyR/T]

but the montero intake manifold won't bolt up or will it?

Its the only mitsu intake manifold that actually bolts up in stock direction.
I have some pictures posted on the yahoo group I think.
Wink is the expert here on what fits and what doesnt.

[mwinkle353]

Montero unit bolts up perfectly. The Stealth/Diamante units will have to be mounted 180* or modified to fit. Those units have a larger T-stat housing, that hits the distributor.
