Several General Questions

[quote name='Cheers!' date='Apr 26 2005, 11:46 AM']A 4 port manifold off a turbo engine can only work with a turbo engine.
A 6 port manifold off a NA engine can only work with a NA engine.
I'm not sure about the interchangeability between using S4/S5 LIM or UIMs. I don't know what teh difference is.
My comment is: You should fix the 6 ports on your S4 NA and don't worry about performance gains from the manifold. Unless you can polish the internals of it. To add to why you shuld make yuor 6 ports work:
An engine's performance is not measured by peak Horsepower, it's a measure of the area under the HP or Torque curve (HP is calculated from torque - so same thing). When you wire your 6 ports open, the area under the curve decreases because you have shitty power at the bottom end. You would lose in a simple drag race off the line if you start at anything below 5000+ rpms if the car beside you had his 6 ports working.
Oh and don't bother with the electronic 6 port, that is just another thing to go wrong. Stock worked, so fix it and keep it stock.

I was not looking at swaping manifolds for increased horsepower or "performance gains" as you put it. I only wanted to swap to FD maifolds because I am more familiar with the fd3 and it's throttle body etc.I was only looking to see if I could swap the intakes to something that I am used to. Come on man, Performance gains and naturally aspriated should not even be in the same sentence.
Regardless It seems easier at from what I understand to just leave it be and get familiar with the odd s4 N/A manifolds.
Thanks for the input.

I agree... if you aren't looking for performance gains... just increase your knowledge about another rx7 component.

You can always polish the S4 manifolds to a mirror finish like your FD ones.. Yum.. those polished FD ones you did on yuor blue car are so nice...

Why thank you sir. Yea I suppose I will just dress up what is there. Knowing my dad he will give it some weird *** two tone paint job anyhow.

[quote name='Rob x-7' date='Apr 27 2005, 03:45 PM']I actually think a S4 upper looks nice just the way it is
when its clean its naturally shiny, paint the fins with some black paint if its worn and it looks awesome as is.

Yea well this car was about as dirty and ugly as could be. It might make a difference with some new paint and a fresh engine bay.
