Howdy S2ki,

I don't want to write a review, but I've been getting a few questions on the kit lately & thought I'd start a thread where I can answer questions instead. So ask away & I'll answer when I can.

Some background on the setup:

03 Ap1
Installed back in late 2014 SOS TS max turbo kit, GTX3576R, ran the previous owners map until dyno on April 22nd 2017 @ Evans Tunning in PA Made 430 HP on a dynapack @ 13-15 lbs, boost by gear.
Berk header back w. a modified flange to accept 3" down pipe, gutted exhaust bc racecar.
1000CC ID
KPro w. Justin C RSX wideband
AEM 320 (currently failing, sticks all the time)
Toda pulleys
Stock Clutch + ACT PP + Toda Flywheel
Shell Rotella 5w40, b4 & after turbo kit
Turbo water lines disconnected this year.

I'm sure I missed something, I'll update this as I remember.

 

So the act HD clutch with oem disk combo is what you're using. Was able to hold the torque with out slip?
Any Reason why you went with GTX 3576 and not the gt3582 recommended by SOS?

 

Correct on the act + oem disc. It holds well when banging & WOT in all gears, but I cant launch the car, it will spin the clutch.

I bought this kit used from a member, so 3576r is what I ended up w.

 

Have you had other FI kits on your S2000 before the SOS kit?

I'd be curious to your thoughts on an SOS supercharger vs this kit.

Thanks!

 

I have not, this is my first kit.
I've never driven a supercharged S either, so my seat experience is very limited.

 

Curious what are oil temps looking like on your SOS kit w/o the coolant lines? I'd be interested to hear others' thoughts on removing the coolant lines. I read garrett's explanation but curious if the center section does get some needed cooling from the coolant while the car is running. I'm sure it can't hurt and probably would contribute to a longer last turbo. @spdracerut

 

This is a great question

Short answer, no oil temp sensor, read here for why turbos run coolant. https://www.garrettmotion.com/racing...or-your-turbo/

Looong answer:

I disconnected the coolant lines summer of this year bc of a leak, although they worked just fine for 5 or so years. I was still running Honda coolant & noticed a small pool while the car was idling in my drive way.
Snugging up the 17mm M14 thread banjo bolt closest to the battery was a breeze. The one between the block & the turbo.. impossible. I even bought a special ratcheting wrench per SOS recommendation, to get at it from under the car, still no go. The space is too tight by the SOS motor mount bracket, I couldn't snug up the bolt, & the goal was to not drop the turbo. So bye went the coolant lines. This was not easy since I had to remove the vtec solenoid, oil filter adaptor, & oil cooler just to get a wrench in there. This, in my opinion, a downside of the SOS kit. Accessibly.

Side note, good luck getting a 7/8th crows foot on the AN fitting from the turbo drain once it loosens up. You have to machine the mouth of it to git around the hose & even then it still wont be tight.
I'm looking at extended turbo drain flanges, but haven't pulled the trigger yet.

Another side note, If you do go w. this kit, do your self a favor & grind off that threaded tab on the turbine housing, it will help w/ installation. Oh & 2 bolts backed out on the down pipe. the one is impossible to reach, the other was easy.

I do wish SOS would of tapped & threaded a second port in the oil filter *ford* piece, to add an oil temp sensor. Either way, it's on me to add one, & I haven't done so yet.
IMO, oil temp shouldn't be negatively effected by removing the turbo coolant lines, if anything it should improve since the coolant isn't being over heated by the turbo while the car is running, & the oem oil cooler/heater has engine temp coolant going thru it. Come to think about it, I don't think the SOS kit clocks the turbo, I could be wrong tho.

Of course w. the coolant lines disconnected, I can't just turn the car off now. Once I'm parked I turn the AC (for the fans to kick on) & the heat w. recirculation on full for 3 min & watch the water temp thru an OBD Bluetooth unit.
It usually settles at 183°, running straight distilled water, then I shut the car off. I think having a beefy down pipe helps draw the heat from the turbine housing. I've been sending my oil in regularly to Blackstone, so I'll be interested to see if they catch any burnt oil particles or any of that.

 

The water cooling is primarily to prevent oil coking from a hot shutdown. It's not necessary for standard operation except for extreme applications like marine use. But those have water cooled turbine housings too. Garrett Motorsports turbos traditionally don't have water cooling (WRC, FIA touring car, DTM). Granted, those typically get replaced as a service item. If you drive easy for like 5-10 min before you get to where you're going, and/or sit and idle, you should be fine. Like turbos on diesels don't have water cooling typically because they run lower EGTs.

 

Are you still on oem radiator???
what fuel did you dyno on?
is the IAT still in the manifold location or have you relocate to intake pipe?
Do you have any video ?
Thanks.

I did relocate IAT to intake pipe. Had videos on my IG, but I recently deactivated it for reasons...
