i want to buy a built motor but cant decide between the too!?!

the 4g64 alm block is a few hundred cheaper even without a core and it supports better low end tq then the 2.3

the car will be used as a dd with an fp-red & pump gas

i dont care about the price, not that i'm a baller i just want a reliable 500whp motor

as of rite now im looking at the buschur 2.3l built short block w/stg3 head or a sbr 2.4l built short block & built head

i was hoping to get some good info between these two short block before i buy but theres not any out there, anyone that has any experience with both these motor please help me make a good choice

i'm also curious about this. i am looking at doing the same setup with a red or maybe even a black. i'm looking for similar power but i will use it for autox

 

the new 2.4 blocks are doing great. They might become the new 2.3..

 

BUMP....im looking at this as well

also,how easy is the 2.4 to work with,will i have to buy alot of galant parts(or which ever car uses that motor)

 

we really need a 4g63 to 4g64 swap thread pinned to the top!

from what i gather they use the same oil pump, 4g63 water pump with a 4g64 gasket and a spacer. 4g64 timing belt, 4g64 head gasket.

timing cover and all that, i have no clue. someone fill in the blanks please!

 

I am currently building my 2.4L high compression motor on E-85 using the FP Black. I will be using this car for road racing and autox/ daily street driving.

 

Everything is the same as the 4g63 except that the 4g64 has a taller deck.

 

yeah, but the incidentals like the water pump deal would be nice to know about.

 

The 4g64 uses all of the same parts as the 4g63. The 4g64 block is plug-n-play into the Evo.

 

not true.

 

The 2.4 is what i'm going with when I build my motor, I have a couple friends with 2.4 and 2.1L from Slowboy and they make sick power and are very happy with them.

 

4G64 has a larger bore.

STD 4G63 = 85mm
STD 4G64 = 86.5mm

4G64 has a 6mm taller deck, so you can run 3mm longer con rods on the same compression height pistons, and same stroke as you would in the 4g63... giving you a better rod to stroke ratio... which will make your ish last longer and rev higher.

 

I'm also currently building my 10:1 2.4L Long Rod w/ 156mm rod and 87mm bore. It should have no problem reving 8.5k all day long. Honestly you can make a 2.4L more rev happy than a 2.3L for a lot less money. The 4G64 block is the way to go.

The other thing you may be interested in is the 4G64 block with a 94mm crank 87mm bore (long rod motor like the 2.2GSC 1.7r/s or 2.3RR from AMS...) You would have a 2.2L that revs like the 2.0

I wouldnt trade my 2.4 for anything.
