2.4l / 2.3l??

[NeoStreamGSX]

if you use the 4g64 block w/ 4g63 head...outcome would be 2.4L. but 2.4L crank in a 4g63 would make it 2.3L. is all this correct. and are there any performance difference between the two...new rods and pistons will be used, but will still be 8.5 compression, possibly w/ the .020" oversize.

The 4G64 is 2.4L. Regardless of the head. But this is a good solid combination.
A 2.3L stroker is a 4G63 with a 4G64 crank and the cylinders bored .020 over ((85.5*85.5*101)/0.3145).

what pistons and rods does the 2.3 use, i know you should put in bigger rods and posably forged pistons but i was just wondering if they come frome the 2.0 or the 2.3

I remeber reading here on tuners that the 2.3 is really a 2.35, no?

1G Rods, and special stroker pistons (wrist pin moved up 6mm to keep the pistons from clearing the deck). Wiseco, Ross, and JE I know for sure sell them.

It's actually closer to 2.32:
Bore = 85.5mm
Stroke = 101mm
so, BBS*pi = displacement in cc's
((85.5*85.5*101)*0.03145) = 23220cc's = ~2.32L

or, if you don't bore the block, you come closer to a true 2.3L:
((85*85*101)*0.03145 = 22949cc's = ~2.3L

Hope that helps.

so does 8 hundreths of a liter make a big diffrence? and yes that helps a lot. thanks!

I'd go with the 2.4l and a .060 overbore. I know with the 2.4L 420A, a .060 overbore equates out to a 2512cc motor. This is plenty big enough to make people scared.

Ive heard that the 2.4 bottom end is out of a old gen galant, like a 87'? I was wondering If I bought one of those motors rebuilt to factory sepcs, would I be able to slap on a 4g63 head without problems? How much power would a block like that handle? Those 2.4 galant motors were 6 bolt right?

I'm currently building a 4g63/64 hybrid. I used a crank from a 95 galant 2.4 ($160 dollars from kragan). Where you get into big money are the pistons, you could save money and use your 7 bolt or upgrade to 6 bolt rods, but I wanted something that was going to take some power so I spen the extra 300 bucks and got Eagle H beam rods. They are really high quality and you get away from the OEM powder cast metal rods. The OEM rods have a structure like styrofoam. I learned my lesson in the past that it is cheaper to get the good rods early so you done ruin more later. By leaving stock rods in my motor and it broke, I ruined my block crank and heads. That was much more than the 300 dollar rods I could have prevented it with. Im serious when stock rods break you will really see how inferior they are. It looks like you broke styrofoam.
