2 L67 Inlet manifold questions

[Brysha89]

1st pic is how ill extend the l67 inlet manifold to add the 4th port
2nd pic is how i want them set up on the block
3rd pic is inlet manifold top down view
4th pic is a side view of the inlet manifold
5th pic is the underside of a ls1/2/3/6 supercharged inlet manifold
6th pic is the best i could copy of a Eaton m90
7th pic is of how i'd like the Manifold to look like ( measurements yet to be done, internaly it will be plumbed to go down into the l98 heads by the bottom of the made manifold will look like the ls1/2/3/6 manifold)
all these are free drawn from looking at the pictures on pc so sorry for it not looking the best.
I am going to set it so the twin inlet manifold rises above heads enough so that the first thing to come off when the heads need to come off the block is the chargers and manifold by doing that will leave enough room to squeeze the fuel rail's and injectors under there.

losh i am fitting it to a l98 v8 not the old buick v6

No, but I'm curious about the manifold and how it's made as I might be able to get one made like you are I assume?

 

[Brysha89]

you just have to plumb it the way the buick is but i dont know how you would go about the injectors they are considerably different to the l67 as it was the l36 ecotecs needed to change heads as the injectors ran through the inlet manifold opposed to the l67 that had the injector holes in the heads and also the buick is direct injected or something or rather and the l36/l67 is sequential

 

[Brysha89]

so i wouldn't know how the charger would react to that, where as the l98 v8 is like the l67 and l36 where it fills and fires each cylinder in its sequence

Hey losh was looking for l98 supercharger inlet manifolds to draw and i think ive found what you need for the buick: https://www.ebay.com/itm/Dorman-Low...190162&hash=item48c4fd7006:g:rHEAAOSwzeldefRU

^^^ That's not a Buick manifold, the ports are in the wrong positions and they weren't produced that late even in the States. The only ones that really exist are for the M62 because of the different length of the blowers.

 

[Brysha89]

mhe though it would be what he needed as it dont look like a l67 inlet and says for buick 3.8ltr

 

[Immortality]

The ecotec is a Buick motor, we call it the ecotec here, in the US it's and L36 but they are all Buick motors and found in multiple Buick vehicles. It's the port spacing the gives it away as to what particular 3800 V6 motor it is from. Also, we have a different inlet manifold from the US who use a banana style manifold on their engines and hence the lower intake manifold you linked.

 

[Brysha89]

but that could be fixed by ether using the us heads with it and fuel rail or port the inlet manifold and heads to be same

 

[Brysha89]

anyway enough about losh's old 3.8ltr immortality and R_J_K_ what are you're thought's on my project?
