4G64 so.... out dated

[solofantasy]

i came across on autoconsumerguide.com, and looked every spec pretty much on everycar...

i discovered, most 2.0L engines can produce 140HP and have faster 0-60s..... wow. like Spectra, Elentra, Focus, etc (well heck with it, RSX-S 2.0 do 200, honda civic Si do 198)

I mean, right now, most 2.4L engines will produce around 160 HP.. for example, the new 9G, Scion tc, camery, (an Mazda3 2.3L produce 160hp) etc.

but our 2.4L SOHC only do 140 HP, 10.3 in 0-60, thats pretty sad. and heavy as crap. maybe the timing is better now with all the new cars, injection and timing must been improved i guess.

[AVERAGE]

Most 2.0's are DOHC which makes abit of a difference.

[cardude03]

i'm not quite sure i understand what your complaining about? of course its not the best engine out there, thats why they dont make it anymore. you even used a perfect example, the new galants, there is probably a good reason why they didnt use the same engines as the 8G's

i would think that things that are outdated our things that are still produced, using old technology and stuff, but if it isnt being produced, then.....?

x2. and if you think about it if the 4G64 came stock as DOHC. our 2.4 would be just as fast as the other cars mentioned. The Galant really isnt that heavy... weighs about the same as a regular EVO.

[DOHCstunr]

i think the 4g63 and the 4g64 are incredible motors.
probably the best out there.

the fact of the matter is your botom end is identicle to the evo or the eclipse turbo depending on your model year , (save pistons)
and to know that that bottom end can hold 350-400hp every day(400 with a glory tune) with nothing more than bolt ons..
well that says something.
the ONLY thing limiting you 2.4 guys is the sohc,
and at that you can still make a ton of power.

but besides power potential.

the key is the quality of those engines.
forged crankshaft, maximum quality bearihs, forged connecting rods, bulletproof cast iron blocks,
just an incredible motor.

to think i put almost 200k miles on my original GS motor dogging on it every single day.
every damn day beating it to hell flying through city traffic stop and go redline shifts race this car race tat car etc etc.
every damn day. i woudl always drive that engien like i stole it.
never leaked oil on me, never smoked a bit.
all i did (and the 1 owner before me) was use mobil one and oem filters.
and just ask matt(peanotation) about the absolute perfect condition that engine is in to this day.

mistu quality= oh yes!

best 4 banger out there hands down.

Here is a probably dumb question from a engine work noob.

Do they even make heads with dual cams for the 4g63 2.4L :duh:

u mean 4g64 right... a 2.4l 4g63 would be punched out or a stroker or both.

Performance wise:SR20. Reliability?Probably its younger brother:GA16DE

[milo111000]

also compression plays a big factor too.. i don't think we got like a really fast car but heck i would say it's pretty damn reliable.

[werperp]

hmm. interesting find i guess? everyone does have their preference.

spectra, elantra and focus arn't faster than a 4g64 carrying car, if anything, they're the same. RSX-S and civicSI both have VTEC and DOHC, which makes a huge difference. you can't look simply at the output per cylinder, since there's different heads, compression ratios, and valve timing.

a stock DOHC 2.4L will rape any DOHC 2.0L with the same compression ratios
a boosted DOHC 2.4L will make any DOHC 2.0L cry, running the same boost

mitsu took a high(er) displacement engine, gave it a relatively low comp. ratio, SOHC, and had it make 140hp EASILY. the 200hp 2.0L that are in hondas have an incredibly high compression ratio and usually the infamous vtec; those motors are making their peak hp output, and there's (relatively) nothing you can do to add to the power output since they're already squeezing out as much as possible. the only respectable friend i have with a civicSI turboed his car, but can only run 6psi at most, since his motors compression is rediculous. so the most he could get at the end of the day is 250whp. you can run 15psi+ on a 4g64 with either head, and easily break that.

[kolio]

I can speak from experience driving two diffrent cars.

1997 Galant DE - manual - 2.4L SOHC - 140 hp

2006 Mazda S Grand Touring - auto-manual - 2.3L DOHC 160 hp

while the mazda is new i still prefer the mitsu. even tho the mazda isn't full manual, in't preety close. when i drive the mazda and get into my 7G i smile at how much better my car goes. engine wise even tho mines a SOHC i take it over the mazdas DOHC. the 4G64 might be a little old but i got 80k on mine and i haven't chnged a damn thing. the Mazdas gone back to the dealer twice for various problems. other than it having better suspension setup, 7G 4g64 SOHC hands down.

BTW the gay ass mazda people have the limit set 115 mph, i found it and was very disapointed!!! and my 7G goes better on gas.

Well said John....Well Said!!! 8-)

The 4G64 was Mitsu's multi platform powerplant choice..it was a STRONG and Quality built motor with enough power to move what it was put into. The 4G64 has been running in Mitsubishi cars longer than the 4G63....simply its a big brother of the 4G63 which is why both the 64 and 63 share ALOT of similarities. The 4G63 allowed Mitsu to have a engine to compete in the WRC...which one of the main rules is to have a production engine no larger than 2.0L. Trust me...if the WRC rules were a motor no larger than 2.4L's, the 4G64 would have the high profile legendary reputation that the 4G63 has. The 4G64 is no means a weak motor....it has the guts to make and handle ALOT of power, but just merely tuned for mainstream use. John pretty much stated what I would and wanted to say...so I won't blabber much on except for this:

Wolf in sheeps clothing= 4G64

Sorry
You are right, I was asking about the 4g64.

[Xrs2]

I'd say its more the Auto Tranny/ECU tune in the 8G that makes it suck compared to those other cars. A 5-Speed would make it a bit faster, by at least 1/2 sec in the 0-60 and quarter mile.

DOHC def. helps uptop. I don't have a 4g64 so I can't really say what kinda top end they have.

[4g63lover]

Here is a probably dumb question from a engine work noob.

Do they even make heads with dual cams for the 4g63 2.4L :duh:


94 GS (7G) DOHC 4G64. Proto's car. and a couple more

I share the same opinion
1st: 4G63/64
2nd:SR20DET (especially on a B13 Sentra.) 8-)

[Arty_Harvy]

Damn, you can run 15PSI on a stock 4G64? HELL YA!!!!!

[4g63lover]

Damn, you can run 15PSI on a stock 4G64? HELL YA!!!!!

just like the 4G63. but I wouldnt push it to 15 psi on stock internals... your motor would hate you... maybe 7-10 safely. with the DOHC of course.

[DOHCstunr]

i'd run 15 psi on it all day.
but only with a good tune and some knock control.

i garuntee the stock sohc 4g64 with a good tune could handle 18-20 psi. given the right turbo, the right fuel system, and the right timing.

with a stock block? i didnt know that.... good info. something to look into when i got turbo.

[DOHCstunr]

Underated is running 16 psi on a stock block with a big boy Greddy 18g turbo.
thats a 400hp capable turbo if you didn't know.

[jtaruc]

What's a 4g64?

[Xrs2]

I can't tell if you are joking or not?

It's the engine code for the motor in the 4 cyl galants

[milo111000]

What's a 4g64?



oh no you didn't!!!!! :firedevil: :firedevil:

[Evofreak7]

if it was out of date then why are there evo guys swapping out there 2.0 blocks for our 2.4 block?

500 horsepower on 93 octane....thats why.

[seth98esT]

Yah the 4g63t is outdated too. Such a POS!

[peanotation]

the 4g63/4 is about as out of date as french toast. been around for forever but it still owns all other breakfasts

[Kwikfox]

:laughing: Hell ya! Why fix something that isn't broke? The 4g64 is awesome, and has so much potential. For those of you who know Toyota motors, the 4age is not as powerful as its hi-comp 4age counterpart, but it has so much more power potential. Do they use the hi-comp 4age for the Formula Atlantic Racing, nope, they use a very tuned 4age motor, well they did, I am not too sure what they use now. :-D


UPDATE: They no longer use the 4age, but they used to.
