Quick question, are I think the 4G63/4 pistons are interchangeable, but are the 4G63/4 rods? Or are the rods different lengths. Will I need 4G64 specific rods?

Thanks in advance,

Rods are the same, pistons are not.

What are the differences with the pistons?

For one thing the 64 is a bigger bore, so the piston is bigger.

So 1G 6 bolt rods from my extra 4G63 block will work just fine?

Sorry guys. I wasn't paying attention. I'm slipping in and out of typing and pretending to work.

I will explain...

The pistons from your 4g63 will not work because the bore of the 4g63 and the 4g64 are different.

4g63 85mm
4g64 86.5mm

So no... the 4g63 will just slap around in there

You will have to buy aftermarket pistons for the 4g64 if you want to do the hybrid combo

If you want to do the stroker combo (4g63 block/ 4g64 crank) you will have to buy aftermarket pistons as well

but what are you trying to do is the question...

4G64 block, stock 4G64 crank, 2G rods, not sure on the pistons yet.

Is it a 7 bolt 4g64?
I usually deal with just the 6 bolts

If it is just a stock 7bolt 4g64 can't you just slap a 4g63 DOHC cylinder head and be done with it? (granted the pistons wouldn't be as strong and other stuff but it would get you by)
