I thought because of the EVO 4G63 block being flipped to the other side you could not use a 4G64 bottom end on an EVO? Or is it the bottom end off the 4G eclipse 2.4L 4G69?

I have a 2.4L 4G69 sitting around so if that’s the case ill just send that to SBR to get it done but if not I would rather order a 2.3L from AMS.

Please help me figure this out I just sold my old DSM’s and want to order my short block on Monday.

 

nope, not a 4g block

galant block as it commonly known is the 4g64

 

So on the EVO 2.4L setup its using the 4G64 bottom end?

 

well, it uses the block and crank but you after market rods and pistons to maximize rod/stroke ratio.

 

Ok got it, I was just trying to be cheap and get some use out of the 4G69 block I have but hey I like the 4G64. Does this also mean that the 4GCS block will work as well?

 

no. and the guy who said yes is only 1/2 right. i literally have a 4g63 block with 2376cc (2.4l), i believe, of displacment.

 

How did you manage that?

 

Really?

Because we DO use a 4g64 block. Its increase in displacement is from the increase in stroke. 100mm (64) vs 88mm (63) and also a bit of a bore increase.
Stock bore on a 4g64 is 86.5mm (64) vs 85mm (63)

The 4g64 is also a taller block than the 4g63. 6mm taller. Which means you need a longer timing belt as well. Other than that, its basically the same as a 4g63 engine of the corresponding chassis. 2G style 7 bolts sat on the drivers side ala' DSM. So did 4g64's in Galants etc of the same years.

When it went over to the passenger side in the 3g stuff. They were able to be used in an Evo. Just like a DSM.

All your misc bracketry etc will bolt up, with the exception of the H20 pump, but we include a spacer. Oil pumps etc. All bolt up stuff.

The 2.3XX motor he's talking about, is the 100mm crank in a bored 4g63 engine. Or commonly reffered to as the "2.3l". Different deck height, different pistons etc.

If you are after a 2.4l short block. Please, I'll be happy to build one for you.

 

While on the topic, What head gasket is used with the 2.4L with a standard bore, 86.5mm??

I was looking at cometics website but couldnt find the right gasket.

 

just fyi, I called cometic to talk to them about it and ordered a 87mm gasket that works with the 2.4L's
