Has anyone tried a race manifold header? If so, what results have you seen?? See the attached link for header details..

How exactly does that work? Since the turbo assembly pretty much bolts directly to the block I dont see how that would fit.

 

Looks shinny.. and it's located only a couple hours from me.. It's mine! lol j/k

 

I've heard good things about these- fitment, quality, etc- however, I don't have one so I'm not sure.

 

All i see is red X's

 

The RX7 Performance book by Mike Ancas suggests that the stock exhaust manifold is the most restrictive component in the RX7 exhaust. But I do not know anyone that has used one of these after market items to open things up.

 

So can somebody explain exactly what that is? Is it for use with the stock turbos?

 

It says, it's a turbo manifold. But doesn't explain if it's for the twins or single..

 

it's for a single turbo

 

are you sure...... cuz there are two opennings in the manifold
