I beleive I am the first site member to get this kit installed. I will use this thread to provide some detail on the kit installation and my impression of its performance and fitment.
Installation:
The biggest issue in installing the kit is that it requires the relocation of the Air Conditioning lines and the battery.
AC lines
I had the AC system purged at an AC shop (no charge) - brought the car home and removed the lines.
I cut the lines and measured the appropriate hose length to have flexible hoses made - then I brought them to a local AC shop. Here are some pics that detail the process:
First you need to cut the lines to get the parts you will need to have the hoses made: The high pressure line (smaller one) can be easily bent by hand if you are carefull - or you can just have the AC shop cut it and re-weld it so it points left and down from the bulkhead fitting that mounts in the firewall. The low pressure line (larger one) will likely need to be cut and re-welded - mine cracked while trying to orientate it left and slightly down.
While your lines are out you should cover the lines that are left in the car so that they do not get any dirt/etc.. in them. Also a good idea to have the AC shop provide new o-rings and a schrader valve (bring the old ones in so that they can match them properly).
To get the hoses made you can use these dimensions:
Make sure you pay attention to the orientation, as you can twist the hoses a little - but not 180 degrees.
Installation will have the lines oriented so they go towards the passenger side from the firewall and then run under the relocated fuse box (shown later).
(this info will be in the install guide - added the detail here since it may benefit some of the turbo guys).
Total cost to have the hoses made was $110 - I re-charged the system myself, expect to pay $75 to have an AC shop do it.
Battery Relocation
The SOT kit will include the parts and wiring required to relocate the battery to the trunk. I wanted to keep my trunk space so I elected to relocate the battery under the hood:
I used an Odyssey 925 dry-cell battery and made my own mounting bracket. The bracket you see below the power distribution block is included by SOT for mounting the fuse box. I have an Odyseey battery tray on order to replace the one I made:
Heater Hose/Valve
The next thing you need to do is re-configure how the heater hose and heater control valve are orientated. The kit includes a new mounting bracket and hose extension that allows you to remount it so that it clears the SC and new Throttle Body.
The hose they included was a thinner wall, and I opted to use a thicker wall hose so that it could be bent at a tighter radius without kinking. They have changed this in the kit so the hose will be black.
Supercharger Bracket
The SC is mounted using a combination of three of the exhaust manifold bolts, the heatshield mount bolts and a lower brace that is also off the manifold. The bracket is 1/4"stainless and looks to be quite strong:
Kit Installed
OK - so I jumped ahead just a bit. More detail will be included later on - inserted into this thread first post.
Here are some pics of the non-IC kit installed. It made its debut at the Arizona clubs annual meet.
I installed the kit with little more than a couple pics from the initial prototype care that was done last year. I would estimate the total time to install at a weekend. Again the pain will be having the AC lines re-routed and the battery relocation. The AC lines can actually be done post SC install if you like - just bring it to an AC shop and have them do it.
Performance
The SOT kit uses a piggyback called an ELF (emissions legal fueling). The ELF uses boost (on board map sensor) and the injector cycle that is being sent from the ECU to determine how much longer the injector needs to be held open. You adjust the tip in (where added injector duration is required), the amount of additional duration per pound of boost, and the maximum duration. My early impression is that it works and leaves the car in a very drivable condition - but it is not perfect. I would prefer that you could map on boost, rpm, etc.. Idealy it would be nice to have a piggyback that allowed you to set a target AF ration (from a wideband) and then have it manage from there.
My current AF is running mid 11's below VTEC engagement with a spike at VTEC engagement to 12.8 that comes back to the low 12's (12.1 to 12.3) almost immediately. From about 7000 rpm to redline it slowly richens up to about 11.8 at 9k. There is a little bit of partial throttle fluctuation (goes rich) but the car is quite drivable.
I will be tweaking the ELF for a few days and will get it on the dyno this coming Wednesday. Not sure what to expect - but assume she will be in the 275 to 285 range at peak with a boost of 6 PSI. The one thing that is nice is that I have 4-5 PSI from 3k to 5k and then it is 6 PSI to 9k.
I will post more updates as they happen and will be adding the A/W IC kit in a couple weeks which will push it to about 7 to 7.5 PSI.
Kit price has not been finalized - but I expect it to be about $4200 for non-IC and $5500 for the IC Kit.
nice install. though it doesnt seem like that there is much more boost you can squeeze out of thing since the pulley is already very small. i like it though, cant wait to see the IC addition

You actually change the crank pulley instead of the SC impeller pulley.
For the S2000 it looks like 8 or 9 psi is the max (due to max rotational speed limit of the Eaton SC) - of course you drop 1 psi of it with the IC. Looking for 7.5 PSI with the IC kit.
WLAURENT the kit looks great! Can't wait to see the dyno numbers.
you seem to have a direct line of communication with them, i am interested in the Heater Hose/Valve kit only. Would you be able to ask him how much it would be just for that kit (bracket, hose, etc).
