I have been browsing posts and noticed alot of bogus info being posted about these motors so I want to state some facts about these motors from personal experience.
First of all a 4g64 is a 7 bolt 2.4l bottom end. If you like crankwalk this is the block for you. I myself wont ever use this block for anything. There are ways to fix the crankwalk problem but it tends to be time consuming and useless when you can get a stout g4cs block that will work just fine.
A g4cs is a 6 bolt 2.4l block. This is the block you want to avoid crankwalk or having to plug holes in the block. I am running 2 of these motors. I have a g4cs with a 4g63 crankshaft in it which creates a 6.9:1 2.1 liter engine that responds very well to boost but has very little low end power. I created this engine as a bandaid to get my eclipse back on the road.
For those of you wanting the cheap route you cannot use the stock pistons and rods with the stock crankshaft and then bolt up your 4g63 head and a big turbo. The reason you cannot do this is because it creates an 11:1 compression ratio. The knock is uncontrollable even using 120 octane fuel (trust me I fried 2 crankshafts finding out). Trial and error has taught me alot about these motors.
For those of you thinking you can use a g64b block best of luck getting your 4g63 tranny to bolt up to it. The bell housing is too wide on the block.
On the engine stand I am building a g4cs 2.4l beast. Wiseco makes forged pistons in a standard bore size which is great if you have a nice block that doesnt require boring. Eagle rods mate perfectly to this setup. I am going to post some pictures of the buildup so you can all see what actually goes into the block and the proper way to build one. This is the fifth one I have built. If you like the feeling of being in a 747 during take off this is the motor you want.
For any of you that have any questions on this setup please dont hesitate to post I will answer your questions to the best of my ability.
