Hi all, just wanted to know...besides the difference in port sizes between the two what are the big obstacles preventing the small port intake manifold mounting onto the big port head? Bolt spacing different? Manifold hitting engine parts? Port/cylinder spacing different?

Re: 4ag big port small port
is the bolt spacing on both the manifold totally the same?
Re: 4ag big port small port
Smallport manifold runs 4 runners whereas the bigport manifold has 8.
Why dont you just get a bigport manifold?

Re: 4ag big port small port

thats the TVIS sitting on the smallport head. no chance
the bolt holes are in the correct positions though.
Re: 4ag big port small port
ahh Grega thanks for the great pic postup needed that, +rep points postedby any chance would you be able to provide me with the small port width and lenght measurements?
Re: 4ag big port small port
thanks for the post, no I dun need to go back to carbs, it's just that I need to know why it's not possible to use either one of the manifolds over the other.Originally Posted by oldcorollas

This is what you need, or need to produce.
Available from: http://www.technotoytuning.com/productdetail.php?p=374 or probably producable locally. Depends on how much your time is worth.

Used on large ports to narrow the port and improve port velocity.....

Re: 4ag big port small port
yah looks neat.. bit pricey for the setup tho, but does include a head and manifold (without the ghey bend for brake booster)
