Good morning all 
Yes I have searched, countless times in fact and have got a solid collection of pages with really valuable resources, however, as said in my introduction thread most threads on HT are not specific to the EK9 and was hoping to get some clarification on a few items from those with longer term experience. I am fairly new to the EK platform but have had an "AP2" S2000 (yes I know it's a facelift AP1 lol) in the past and multitudes of VWs on which I do all of my own work and maintenance.
As it stands, in terms of performance mods I have a custom N1 style exhaust with a Tegiwa header, M2 whale peni5 intake, Spoon ECU and new service items such as plugs and leads. The car has recorded a 14.5 1/4 mile on Dragy at 155.63km/h with a very soft launch so it's no slouch as it stands.
Now, before I get bombarded with comments about the Spoon ECU and the need for an EMS, that's not my goal with the car, I wanted to retain the OBD2A ECU with lower vtec engagement and increased redline so the Spoon worked for my needs. I understand that any further mods may not give the best possible gains without tuning but that's a different discussion altogether, so without further ado, my questions :
1. My current Intake Manifold and TB look a bit sad, so I was researching the S2 Pro and S2 Ultra Street manifolds to add a bit of shine to the bay, however I can't see anything definitive that these intake manifolds are worth it on a B16B with minor bolt ons? I am leaning towards buying a second P73 manifold and cleaning it up nicely and potentially porting out with an S2 66mm Alpha series TB. Is the TB a waste, it's the smallest I can find but not sure it's warranted. S2 Pro would be better due to MAP relocation to the underside but at 68mm for the smallest option I fear it's too big.
2. Camshafts. Firstly I have been offered Toda A2s for the car, which will warrant valve springs and retainers, so would going for S2 Tuner stg2 not make more sense? I understand without an EMS I won't see huge gains, but really just looking to carry more power as close to 9k rpm as possible.
Secondly - Has anyone fitted S2 Tuner stg1 in an EK9? It seems they won't make more than a few hp than the CTR cams but the increased duration and minor lift might be what I want.
Spoon cams and throttle body would have been my go to, but sadly hens teeth they are LOL.
Thanks in Advance
