4g64 Block Height / Cyl Head Volume

[spyderdrifter]

So I'm starting to do all the planning for my performance build and have begun designing it on paper before I start the process of buying my parts. I need the block height for the 4g64 engine so I can start this. I've looked but haven't found it yet. Does anyone have this info available? Would be great.

The deck height is 6mm taller than a 4g63 I believe.

You are correct, but I haven't been able to find the 4g63 block height yet either.

2.0 deck height 229mm
2.4 deck height 235mm

Thanks 2slow4now You are awesome.


Okay, I just changed up my title. Can anyone tell me what the cc volume is of the combustion section of the cyl head (4g63 of course)?

Cylinder head volume changes, depending on how much milled, what valves are installed. how old the casting was when it was poured.

Advertised is 47cc

The average I see with stock valves is 44-45cc

The smallest has been 42cc with +2mm os valves.

If you check my bit of a build thread, more like my notebook. You can get an idea of how different head builds work out.

Good info. Right now I'm just trying to get the baseline OEM values so I have a good starting point to work with. I won't be building the engine next year, but want to get all this done ahead of time and enjoy the process going from the math and paper to the real deal. With the OEM numbers and can tweak and change everything to see which way I want the engine to go. I'll use 45cc for now. Thanks Bogus (those rings will be going in next weekend).


Very nice. I just read through the first post. It's now book-marked for my reference
