interesting.
Can this work with an after market header and no heat sheild?

Thanks, good to know. I know that the Mugen comes with a new heatshield but not sure about bolt locations on that one.
The brackets do work with the AP2 Mugen header.
Heat shield top mounting holes were opened a small bit..
I also cut a small area off of the front of the heat shield to make room for the lower supplemental bracket that supports the nose pulley.
The Mugen shield is closer to the block then the OEM one that why it was necessary to cut a notch in the shield to make room for the front supplemental support bracket.
The Mugen header should increase the end result power output at the wheels a small bit but more importantly this increase in power will also come with lower boost pressures (AKA more efficient engine = more flow+ more power and lower boost pressures)
Then there is the option to change out the drive ratio to increase the boost to gain even more power.

WLAURENT,
I wonder if you might answer a question for me. It seems you are running the supplemental injector on your setup, but I guess I am not following if that is because you are using a higher boost pully or if a supplemental injector would be necessary for whatever level the "Stock boost" pulley will be in the kit.
My desired path would be to purchase a pretuned NA EMU that Twizted is selling and play with that for a couple months in the spring, and wait for a few bugs to be worked out of the kit, pick one up and use the previously installed EMU and retune. I am just hoping to avoid the complexity of bigger injectors or supplemental injectors if stock ones will flow enough for a stock boost level.
Oh, and are you running a reinforced dif of any sort?
Thanks
Vader

I am planning to switch to larger injectors soon - probably 500-600 range Seimens DEKA, but will still keep the sub injector as it provides an evaporative cooling charge along with some added fuel. Of course I will only be spraying a small percentage of the over-all fuel with the sub once the larger ones are installed.
Next step is to install a 135mm crank pulley and re-tune.
I believe the base kit will come with the 110mm pulley and no IC, the 126mm with IC will be offered as an option.
Running stock clutch and diff - 1/4 mile and dropping the clutch are not really my thing.

To keep the stock injectors you would need a FMU to run up the pressure to get the needed fuel.
If not using the extra injector
I have looked at this configuration and this setup should work fine.
Stock Injectors
Upgraded pump (for flow and pressure)
FMU
Emamage ult
Basically what would be going on is the FMU would get the fuel delivery in the ball park and the ULT would fine tune the A/F curve.
There is a potential benefit to doing it this way. (unproven in the S2000)
The addition pressure and the use of the stock injectors would give a better spray pattern and better atomization of the fuel then a larger injector with lower static fuel pressure.
We were able to get 20more Ft/lbs out of a Supercharged Miata by using only a FMU and stock injectors then a set of 550

WLAURENT or MugenRioS2k, when do you think you will try to max out these kits. I mean run at or a little beyond the official redline of the blower.
I would expect that the AP2 would make more power since when stock, they are able to put down the same if not omre power than an AP1 at a lower rpm. This would equate to an ap2 being more suited to maxing out the blower since it would ultimately use a lower effective redline than the AP1 to achieve the same power. In theory I guess haha.
I was thinking a setup with the inlet similar to WLAURENT, running the blower ~ 18,000 rpm with a front mount intercooler and water injection would be the ultimate setup with obvious bolt ons.
