Well man,I cant believe you didn't have the car to drive for the last 4-5 months...And you have gone in quite a bit of trouble and much of it couldn't be fixed by you.
I couldn't imagine how you felt when you saw the car few weeks after few weeks and not be able to drive it.I can say from experience that maybe 2-3 weeks i could resist the WANT of driving the S2000 but after that you want to drive it more and more and its painful...
...I have few questions about the IM..
these are in case you took measurements..or maybe Hypertune can answer,its great when there is Manufacturer support.
First.How Long are the runners?What's the Size of them In Width? And how deep or how long is the space between the start of the runner and the Plenum Wall. I see that the plenum Wall isn't Straight. and the length i am asking about will be different in all runners. I Measured Stock is 25cm deep and that's around 10".The runners on stock are 18-19cm and their width is 52mm which is around 2".They are Oval as you know and the width is on the oval points.Also are the runners round or oval on the HT?
anyway i know that our OEM plenum is designed this way-short runners small plenum to function good at high RPM and that Honda engineers dumped the Variable IM Type in Favor of the short Runner/plenum.
it seems that this manifold is designed for use With boost and wouldn't Do much Good on Stock NA and possibly will loose power. Large plenum is probably Known Boost positive...And i don't know what will this IM do for SC Setup.Probably turbo only? Since SC relies on NA characteristic till 3-4000Rpm and doesn't see that much boost till the last 2-3000Rpms.At least stock boost SC.
I think the main reasons they didn't test the IM because it cant loose any ponies when boost is in the Equation,and i think that NA is another story,since air doesn't get forced in to the Engine.
I hope everything works out and was worth it. I am installing mine CF IM on the car and was thinking how the maker didn't make a IACV flange on the IM and that can be fixed tomorrow by me,but other than that everything went Quite fine like it was stock. The only problem i have now is with the BDL TB that matches the Port of the CF manifold that doesn't have a Second Hole for the IACV valve to get the air. The BDL doesn't have two IACV holes like the Stock TB but has only the upper hole and the CF manifold has the lower hole.So i plan to make another hole on the BDL TB.
And few words on the HONDATA gasket. I found out when i took it off that it is a bad copy of the Stock Gasket and it doesn't match Good to the Head opening and OEM IM opening.Somewhere its bigger and somewhere it stands out and hurting airflow and not by a little.It has to be trimmed to be Good as the OEM gasket so in the end i urge all Hondata "TO Be" users of the Hondata Gasket to compare it to the Stock gasket and make any Necessary Adjustments to it so it wouldn't hurt Airflow.(i didn't do this when i installed it since i Thought it was an Exact copy of the Stock Gasket which it isn't.)

Alrighty let me try this:
the runners are round, and as for the measurements idk at this point but i'll try to figure them out for you.
Where did you find a CF intake????
And i'm going to trim the gasket if it needs it when i do the head gasket seeing as there should be a deffinitive line where i need to trim by then.

By the sounds of the botched HYPERTUNE design , dont think many are having much luck in getting these going . There are a few problems of them cracking as well .
Nice looking manifold though , pitty bout the down sides .
