One of the few beautiful reasons why I chose to swap this motor into my car was how modular this family of motors was.  There are just so many Factory configurations, let alone stock ones.  Here is a short list:

• 4G61 - 1.6L (Summit, Colt Motor)

• 4G63 - 2.0L (Turbo, N/T, DOHC, SOHC, Wide, Narrow, 6bolt, 7bolt, Evo 4+, aka: G63B)

• 4G64 - 2.4L (N/T, SOHC, DOHC, Wide, Narrow, 6bolt , 7bolt, aka: 4GCS, G64B)

People have also mixed up some of these parts too!

• 2.3L "stroker" motor (2.0L Block, 2.4L crank, Custom Rods/Pistons)

• 2.1L "destroker" motor (2.4L Block, 2.0L crank, Custom Rods/Pistons)

• I'm still waiting on a 15,000rpm 1.6L crank in a 2.4L block :-D

In this section I'm going to talk about what little I know about these different blocks and combos.

This is my latest motor of interest.  DSM guys have been using this bottom end for a few years.  It comes in several varieties: narrow and wide bellhousings, 6 bolt and 7 bolt (1G and 2G).  The really interesting thing is that its basically the same casting as the 4G63.. only with a 6mm higher deck height, a larger bore and longer stroke.  It doesn't have as high of a redline as the 2.4, but it still kicks the 2.6's ass.

I think I skipped the most important thing.  The 2.0 DOHC head bolts to the thing!  And even more important to us RWD guys is that the wide 6 bolt version is available in U.S. D50 trucks.  This, as you might have figured out means we can use the Starion flywheel, clutch, slave cylinder and transmission.

There are many technical details of this motor that I am slowly learning.  I know it uses the same rods as the 4G63s, has ~9.5:1 compression (yuck).  So basically I have to buy a block, head and pistons and get started!

Sorry.. not too many photos right now... no money either!
