The official designation is 4G69. The link I posted above provides all the detail changes to the engine and how it is different from the 4G64 (lower deck height, lower weight, etc)

 

The US Starion came with a turbocharged G54B truck engine which was a 2.6L SOHC. I have seen some Starions from Austrailia and UK with 4G63's in them but I'm not sure if it was swapped in or came stock for those countries.

 

Dah...that's right. I've seen pictures of an Aussie Starion (which is probaly where I fubar'd) that had some sort of ancient 4G63. As for evomk8, I'm a retard and should actually look at posted links. Yummy tech info on that, thanks.

 

A G63 is a swapped motor for the starion/conquest.


"The official designation is 4G69. The link I posted above provides all the detail changes to the engine and how it is different from the 4G64 (lower deck height, lower weight, etc) ."

Why G69? It hasn't increased in displacement.

A G91 = 1.5L. A G92 = 1.6L. A G93 = 1.8L. A G94 = 2.0L.

A G61 = 1.6L. A G63 = 2.0L. A G64 = 2.4L. A G69 = makes no sense.

A G72 = 3.0L. A G74 = 3.5L. A G7x = 3.8L on the endeavor. I don't know the number.

Mitsu has steadily followed this rule, unless hinting the end of the line for the block.

Also, there is a gen 1 and two for the G64. Also, applies to the G92 with 3 gens of the motor. then, mitsu followed another whammy by having two different gen for the true G93T.

 

As far as I understand there are two reasons for the jump to G69:

1) The block has been reduced in weight (including lower deck height for the head design).

2) This will be the LAST version of the 4G6 series. After this, will use the Global Engine Alliance engines. They actually displayed the 2.4l I4 that will replace the current 2.4l I4's. It is expected to be a MIVEC GDI combo...

Access the Tokyo Motor Show site to see.

 

Oh, Ok. So, Mitsu is making the end of the 4g6x block. I also see Mitsu is about to end the 4g9x block. It can't get any bigger in bore.

What's the engine code for the endeavor's 3.8L? It has to be 6g7(something).

For a global engine, I'm kinda thinking Chrysler w/ Mercedes string pulling might have some say in the 4 banger market. Well, it's global streamlining of products and profits.

 

The 3.8l V6 in the big Montero, Endeavor and new Galant (and presumeably the next Eclipse) is coded 6G75.

In terms of the Global Alliance engine: Chrysler, Hyundai and will all do their own tuning (like MIVEC and GDI) on the shared aluminum block designed by Hyundai (but originally based on a design... I think).

 

Huh? 16 valve sohc engines have been around for a while now. You've heard of the 1988 Honda Civic DX right? 1.5L 16 Valve.

Hmm, one look at the block and head design, I don't know. They seem different to me. You know how some parts on the 4G63 and 4G64 are interchangable and some parts on the 4G93 and 4G94 are interchangable. There must be a simpler reason why they chose the engine code 4G69. They changed the design enough to where the engine is different enough to need the drastic change of 4G64 code to 4G69 code. One example of Mitsubishi's engine code is that on the Mirage 1.8L and the Lancer 2.0L. According to Dave at RPW, the engine is the same with reworked internals, and made as a higher liter engine. When some folks at the Mirage site wanted to swap the head for the Lancer head, Dave at RPW said it wasn't worth it since the head was almost the same and power small power gains wouldn't be worth the trouble. A second example is the 4G92 Mivec motor. There has been a rumor that the DOHC Mivec head of the 4G92 will work on the 4G93 a.k.a. the Mitsubish version of the Honda LS/Vtech Frankenstien conversion. That being said means that the 4G92 is also similiar to the 4G93. Now if the Rallyart motor is essentially the same with 4G64 but with a Mivec head then Mitsubishi probably would have had the 4G65 code. Would it also be safe to say that a Mivec head swap be possible on the 4G64 from the Rallyart motor if it is essentially a 4G64 with the Mivec head. When I went to Mitsubishi and looked at the Rallyart engine with my uncle who is a Mechanic at that dealership. We agreed on one thing, this motor if based off the 4G64, has gone through some drastic changes. The 4G94 motor looks more like the 4G64 than the 4G64 and the 4G69. Only when peeps starting tearing these engines apart will we really know how different they are.

Oh and for the peeps who want to swap in the Rallyart Motor, OBD III is in full effect on this motor. Have fun.

 

Whether or not it's a good thing, you haven't told me anything I don't already know. You may think that the new 4G69 looks like standard Lancer motor but that still won't do you any good. 6 series heads will not fit on 9 series blocks since THEY ARE DIFFERENT ENGINE FAMILIES with different block and head mating points/surfaces. This was brought up a long time ago when the idea of putting a DOHC 4G63 head and intake manifold on a 4G94 was proposed. The 9 and 6 series also have different shaped intake/exhaust ports.

 

Huh? Of course the 6 series don't bolt to the 9 series motors. I don't know where you got that idea from on my post. Also you said that I said that it looks like a standard Lancer motor, wrong, I said that one look and you can tell, this AINT NO 4G64 WITH A MIVEC HEAD! That was the point that I was trying to make. Re read the post and let me know when you really read it. Then you'll learn that 16 valve in SOHC is old school heheheh.

 

well i think the argument here is that the 4g69 will fit in the 02-03 lancers because the 02-03 and new lancers have the same chassis and more importantly, same engine bay.

 

but will it bolt up to the tranny???

 

probably not, in this case u'll most probably need to transfer the 5 speed that comes with the ralliart lancer. there will be VERY VERY minimal modifications tho. that's my guess..

 

ITs 4G69
