1G Anyone put a 4g64 into a 1g?

Hi, I was wondering if anyone has put a 4G64 into a 1G, I find a ton of 2G threads, but no 1G. Thanks, -Dave

its pretty much the same thing. their is a pink 1g in the driveway with a 2.4 in it

I thought the 1g guys had to run a 4gcs instead of a 4g64 if they wanted a 2.4.

it really doesnt matter. early 4g64 that came out of the cars where 6 bolts. you can use the 7 bolt it works to. as far as the electronics you use the 1g cas. just thats what the 2.0 used. all you are is swaping a 2.0 short block for a 2.4 short block nothing really changes. all the wiring stays the same, so do motor mount. you use the same clutch. 6 or 7 bolt dependent.

Hmm never thought about it.... Only problems i can see is the motor mounts. And that may very between newer and older models of the 4g64. Im not certain on that though.

When you put a 4g64 in, you will need to use 2.4 dohc cam gears and timing belt for the taller deck height.

This is exactly what I was refering to. I know my 4g64 dosent have provisions for the motor mounts on the block that a 1g would need.

If it is a 6 bolt 2.4 than it would technically be a g4cs. The 7 bolt 2.4's are called a 4g64. The 7 bolt block doesn't have the provision for the front roll stop on a 1g. There are holes for the rear roll stop however.

your guys sure.... i know for sure that true for 2000+ blocks. and im 100% sure that they are there cause my roommate has a 2.4 1g

He has a g4cs if it has the engine mount holes on the front. Here is a 4g64 block, notice that there are no bolt holes in the front of the block for the motor mount bracket to bolt to, just like a 2g 7 bolt 4g63. These engines were used in galants and spyder eclipses which use the same mount setup as a 2g turbo engine with the mount brackets on the transmission.

nvm.

 

[bryanwheat]

nvm.

Have you ever worked on a 1g before? There are no bolt holes on that block for the engine mount bracket.

You see the bolt holes on the lower left side of the engine, the other block doesn't have those.

I am 100% sure that the 4g64 block that is is my Dsm dosent have the provisions for the 1g motor mounts. I'm not saying that there isn't a 4g64 out there that will work in a 1g since there are so many variations of the 2.4. I'm just saying you better make sure you get the right one to bolt into your car. I just remember during my 2.4 research for my own swap that 1g guys had to use the g4cs blocks if they wanted a 2.4.

Are all 6 bolts referred to as the 4Gcs? I know mines is but it came from a 1986 Galant. Same as the 4G64. Did mitsu change the block numbering when it went 7 bolt? And as stated above, just use 4G64 cam gears and a 4G64 timing belt.

 

[jimbob_843]

Just do some research on it. 2000 and up eclipses have a 4g64 DO NOT USE IT, it will not work it mounts 180* different. The 4g64 out of earlier galants and eclipses will work BUT they may not mount due to it not having mounting holes on the bock. The older g4cs as stated above does. That would be the easiest route. Dont forget,
You have to block off 5 oil drain holes in the block
You need 4g64 DOHC cam gears (from 96? Galant DOHC)
The rest is pretty basic bolt on parts specific to the motor.

Which timing cover works, 2g? I know about the front motor mount, cam gears, etc... I have read all available info on the swap, just haven't found info on 7 bolt 64 in a 1g.

 

[jimbob_843]

Depends on which block. The 6bolt i would assume needs the 1g style. Also you need the timing belt from that year galant with DOHC.
