cheers for your input

love

discount the atr mani
fuji or mugen is a difficult choice

depends on condition - some pics would help

dyno all three will be very expensive for you but interesting for us

ATR will be less restrictive than stock but still not great assuming its the same as the Type S in design.
Even the Mugen IMO wouldnt be the best. But still great.
I think the Fuji is the dark horse.

But unless its Hytech its wrong.

I'm going to go out on a limb here and say Mugen and Fuji will be the same.

they do look very similar

how much better than a standard ATR Manifold do you think either will be, will it be worth the hassle of making it fit?

On a standard ATR engine with a decent catback exhaust and decat you'd probably see an extra 5-10 bhp I recon. The ATR manifold is superior over a standard Prelude mani because of the larger primaries and that, but it's still a mass produced cast item at the end of the day, so they all have their defects and casting marks.

How much work is required to make the Mugen or Fuji fit? Is it just cross-member clearance?

I wouldnt even consider the ATR manifold if i had the fuji and mugen.
