4age intake side (port) dimensions

[Project D]

YES ^^
Fixing Point are exactly the same
Like I said, the only difference is the lenght of the port

Yes, but the smallport head ports from Bible are much larger than standard.
Looks like these are dimensions after enlargement, because thats almost bigport port size

I have some previus drawing friend made when he was making adapter for bigport head.

There were no dimensions in CAD drawing so i printed it out and made it by hand... sorry
And than photod by phone. sorry x2.



If anyone need it in DWG, just let me know your email and i'll send it
I still need smallport head sketch

[Project D]

It's definitely NOT smallport head on TRD bible
If you take a look on the page 202 (juste before the size) you will see the CR: 9.4:1 is for bigport! smallport have 10:1

I will take some pictures after my work (in 1 or 2 hours) I have a smallport head on my desk at home

[Project D]

Ok first, the pictures !

-Smallport VS Bigport:



And bigport gasket on smallport head

As you can see, 65mm (the length of the port on the gasket) is bigger than the exterior of the port itself
That's why I was sure about myself when I said that is not smallport head on TRD Bible.

Now I have to check on my files to find my CAD drawing of the smallport dimensions


EDIT: My CAD drawing HERE
