ATP vs. INA manifolds

[Ibiza125]

Right I know there is alot of information on this, but I sort of need a quick answer before I sell my INA.

Basicly my question is which one is better? In terms of flow and build quality.

I know that Issam has a very good customer service if it does crack, what about ATP?

Also my ATP will be used, whereas the INA is new so I would have more come back on it... Probably just talked myself into keeping the INA and selling the ATP just writing this post!

From the pics I have seen they look identical and in k0x terms I don't think you'd notice an appreciable difference in flow. Both are known to crack in the same place

I wouldn't say there's anything between them though I've not seen an ATP mani in the flesh

I think the ATP runners are larger internal diameter.

"on the road" difference nothin at all

Cant comment on which manifold is the best really, but like you have mentioned I would go with the INA as its newer and you will have some kind of warranty on it.

It also depends on what the ATP manifold looks like as they did do a revised version, due to the cracking problems, I have a brand new revised version sat waiting to go on my car, it has some large reinforced ribs on the runners on the underside. However I would like to add I dont know if this does stop any cracking as its not been fitted yet.

Hope this helps, decisions decisions.

How do you know that?

assume he's talking about daily, town style drivin

So an extra 5-10bhp at the most probably Dave. Be perdantic if you like but which ever manifold fitted, one may pull slightly more than the other on the dyno but the difference will be so marginal If nothing at all that it will come down to driver skill "on the road"....

I'm not being pedantic.

I'm always concerned when I see sweeping statements and misinformation posted on SCN.

Ok Dave on a KKK turbo between the two manifolds yeah it's a really sweeping statement.

Your right, withot proper research, logging, back to back dyno tests, my original statement was foolish and premature!

I retract my original statement, there could be massive differences, you might break the 300bhp barrier with the ATP mani and only ever achieve 280 with the INA one, so the difference could be light and day

but we dopnt know for sure, could be pap all of difference,

shall leave you to decide which one you sell on.
