2.4 in Talon?

[badabing33a]

i finally found a motor. well, 3 of them. i was wondering if a galant 2.4 will fit in my 91 talon nt. how will the wiring be? a guy that races at my track has a talon, and 4 engines. 3 2.0's and 1 2.4. i want the 2.4 if it will work. just wondering. let me know. thanks guys.

I think the 2.4 is the 4g64 stroker. I am pretty sure that this engine will fit in you talon. I know alot of people who switch to this engine to get to get a better response from a larger turbo. If you are keeping the car N/T, I would say that's a good idea for an engine. Just upgrade you exhaust so the engine is not so restricted. This might help you for future referenced Mitsubishi Engines

you can see that the 4g64 is almost 2.4 liters at 2350 cc. It came SOHC and DOHC and was used in the GS and RS. Hope this helped

You will need 2.4l engine out of a 89 sonata. Not a 4g64, that is a 7 bolt version. The sonata's have a 6 bolt 4g63.

 

[badabing33a]

hmm...2 different responses. Uhh ohh.

 

[Hubbell91Tsi]

sonatas have a 6 bolt g4cs... Different block.

Which is what he would want.

 

[agentorange313]

thats right, sorry about that. The sonata does have the 6 bolt set but. I had the same idea for my n/t 91 talon but I sold it before I could complete that project.

You can use a 4g64 block if you want to, and use a 4g63 DOHC head too, unless you get a 4g64 DOCH from the 94 Galant. If you are going the 6 bolt route, you can get a 4g64 6 bolt engine prior to 95 in most applications that had the 4g64.

 

[badabing33a]

so if its a 6 bolt DOHC, itl work? This is probably a stupid question anyway but ive never even seen what the galant engine looks like. I did some searching on here prior to asking but couldnt find anything helpful.

 

[interex]

The DOHC 4g64 only came in the 94 Galant. If you want to make your own 4g64 DOHC, my suggestion is to use a 4g63 head on the 4g64. The 4g63, and 4g64 look almost identical in every way, as with the g4cs. I have a thread on here of my 7 bolt 4g64 with a 4g63 head build, which is on hold for now... you can see by searching 4g63 to 4g64 swap.

What year Galant motor is it?
You need the motor out of a SOHC Galant 1985-1987 2.4L.
Motor code G64B.

You don't necessarily need just that engine. Also the OP could also use the G4CS out of a 89-91 Sonata, or a 7-bolt 4G64(a few oil drain holes have to be plugged). Keep in mind that putting the 4G63 head on the G4CS/4G64 block raises the compression to 11:1 from the smaller 47cc combustion chamber.

do you have any proof of this

 

[dylnwit]

a g4cs block is nearly identical to a 4g63 block, the main differences are that the deck is ~10mm higher, and the bore is a little bigger. On the 4g64 block, some oil passages on the block must be plugged because the 4g63 head does not have the same passages. Probably the easiest route would be to do a g4cs block with the 4g63 head, or the 4g64 block, also with the 4g63 head, this way, you are really only changing displacement, instead of all the sensors. Stick with your 1g head, and it should go smoother than trying to swap to the SOHC head that most 2.4L blocks have.

I've been researching this subject for quite some time, and if you have searched this forum there is plenty of info on this.

The 4G64 deck height is 6mm taller than the 4G63. The 4G64 has a 86.5mm bore and a 100mm stroke.

I can't find any threads to back up what you are saying. I have always read info saying that if you take a 9:5:1 compression 4g64 block and put a DOHC head on the compression stays the same.

how are you calculating this increase to 11:1

 

[rush2252]

AJ what most people are failing to say is this is going to be alot of money. Im still assuming your on a tight budget?

I think youd be better off finding a wrecked turbo car and accomodating all of the wiring ecu engine and swapping it in as I suggested when the motor went. You idea will work but in the end your going to have as much money as the turbo swap and still be Naturally Aspirated.

Good Luck either way

I remember seeing it just got to go back and find it but mean while read this.

How dare you make me work , here check it out:

[m_0ney_pit]

there seems to be confusion in these threads. The only thing that matters is the volume of the dish in the SOHC head and the DOHC head and they have been measured and confirmed to be the same. so the CR will NOT change.

in the case of the SOHC--->DOHC for the 4g64 swap the bottom end is what determines the compression ratio.

If you really want a 11:1 CR your only option is to get some new pistons but I don't think any one makes pistons like that for the 4g64. I have only seen stock CR aftermarket pistons and ratios lower than stock.

Ok, yeah they are the same(47cc). I found the reason the 4g67 has the 43cc head and the older 8-valve 4G64 is the the larger(68cc?). I thinking thats where the confusion is coming from.

 

[jrohner]

Using the 8-valve engine (pistons) with the 16-valve head is what makes the high compression.

 

[interex]

But I don't know if it's as high as said above. I haven't found anything that says it's 11.1, especially without knowing the compression of the pistons.
