Hi im wondering what manifold is good value for money.Im guessing all fleabay manifolds are junk?
Do i need to intercool at 6psi , also are there any good water intercoolers available?
Cheers.

 

Someone here uses a water intercooler, Y8S I think. You dont need one.

IMHO you should intercool at anytime if you can, if you cant 6psi is fine as demonstrated by the begi S kit.

Begi manifolds are awesome, fleabay manifolds are hit and miss.

 

Y8s used to run a water to air IC. He now runs air to air. The water-air ICs are less efficient and require more equipment to work. I also think richyvrlimited has one on his supercharged miata.
You don't really need an IC at 6 psi. If you didn't want to run an intercooler you could run water injection and even have room to turn the boost up. I recommend intercooling or water injection just because I like a cooled intake charge.
