4g64

[x-pride]

Are you asking what brand of rods and pistons or what specs are needed to build your 4g64T?

Most people use the same rods as the 4G63 and then use custom pistons. I used Eagle rods and Ross pistons in mine.

You can buy the pistons from a lot of places. Magnus Motorsports has a wide selection of pistons with various compression ratios. I wouldn't go higher then 8.5:1 for a pump gas car but that's just me.

You dont need custom pistons (wrist pin hight) unless you are putting a 4g64 crank in a 2.0L block which would make it a 2.3L. Rods, wrist pin hight and bearings are all the same between the 4g63 and 4g64 motors. (6 bolt = 6 bolt and 7 bolt = 7 bolt.. Duh)

The 4g64 has a deck hight 6mm higher than a 4g63, there for since the 4g64 crank has a stroke 12mm larger, 6mm TDC and 6mm BDC... The pistons and rods are the same specs except for the cylinder size making the pistons 1.5mm larger in the 4g64. 85mm bore in the 4g63 and 86.5mm bore in the 4g64. Just some tech info.

Some of you know this but for others who dont...

There you go. You learn something new everyday. I started my 2.4 build in 2002 when people weren't as knowledgeable.

So i can use 6 bolt 2.0 rods in my 6 bolt 2.4 and dont have to use offset

Wiseco off sets the wrist pin to help with piston slap on warm up, Ross and J&E pistons have the wrist pin in the middle of the piston. So its a good idea to install the off set wrist pin piston the right way (arrow or dot to the front of the motor, i e timing belt side). But having the pin moved up or down in the piston to account for a longer/shorter rod, or longer/shorter stroke is not needed as the 2.4 pistons are over the shelf now. Installing a 2.4 crank in a 2.0 block would need the wrist pin moved up in the piston to account for the shorter deck on the 2.0 block.
